Hi Folks,
Thought I would start a new thread for feedback on the new Bryston BHA-1 Headphone Amplifier.
Below is the response PMC got from their demo at the 2012 Bristol Hi-Fi Show.
MEMO: To All Bryston Customers
SUBJECT: NEW Bryston BHA-1 Headphone Amplifier
Dear James
Feedback from the Bristol 2012 S&V Show on the BRYSTON BHA-1 HEADPHONE AMP.
Demo System:
• Sennheiser HD800 & HD650 (Single ended)
• Bryston BDP-1 Digital Player
• Bryston BDA-1 External DAC
• Bryston BHA-1 Headphone Amplifier
(http://www.audiocircle.com/image.php?id=58658)
CUSTOMER RESPONSE TO BHA-1:
• Super product, thumbs up from all persons who used the BHA-1
(So much so that Sennheiser were sending clients for demos as it was far better than theirs)
• Easy to use
• Liked the build quality
• Superb bass response
• Has the ability to drive any phone plugged into it
• Greater high level performance than other products
Kindest regards,
Keith

Excellent, I'll get my PS's warmed up and ready :)

I'll have to demo the BHA-1 with my Ultrasone Pro-2900s as soon as it arrives at my dealer.
Amazing products..

Hey guys,
In anticipation of the launch of the Bryston BHA-1 in a couple of weeks (hopefully) and as a thank you to anyone who comes in on Saturday, to our PMC/Bryston open day at Zinc-HT, I've managed to get the bosses to agree to hold a draw at the end of the day for one lucky winner to receive a new pair of the award winning Grado SR325i's absolutely free.
These normally retail for around £350, it was the 325i's that I first heard when comparing different headphones which led me down the Grado path to the PS1000's that I eventually ended up with, they really do sound great, here is some more info -

I'm going to get Mrs Vipers to sneak in and register, I'm sure no one will notice ;)

How about a tubed model.

Oh please James , never go the tube route. I like Bryston for what it has accomplished in the SS world. :thumb:

Not a bad attempt considering we only opened 18 months ago :lol:
But that is good enough for me :wink:

Uhm... Oops... In that case it was another place that had Bryston.
I only strolled in then, but it made me realize that a Bryston amp would be a good replacement for my old Aaron amp.

I brought my Audeze LCD-2 at the Montreal show in hope to find a suitable amp for these. I currently have a Perreaux SXH-2 and it's sound really good but I have to push the amp at least at 3 o'clock position on the volume knob to feel my music (I listen really loud). As I was on a mission, I intentionnaly skipped all the speakers demos (much more present than headphone as you can imagine).
At the show, I tried Centrance Dac-mini, Yulong D-100, Grace 902 (all dac + amp) and Woo Audio WA6-SE. They all sound good but not better than my Perreaux (the Woo Audio was the best of the group).
Then, just out of curiosity, I have decided to stop by Bryston room. As a Canadian, Bryston have always been a proud and mythic brand for me. I have Considered some of their products when I was younger but never been able to afford any Bryston products.
I didn't expect to find any headphone related products. But at the end of the room, past all the speakers set-ups, there was this table with two headphone amplifiers prototype (one black and one silver) along with Grado headphones. The silver one was set-up for balanced headphones in balanced configuration from the source. Even if my Audeze LCD-2 have a SE plug, I tried the balanced set-up.
Listening to all genre of music but mostly to electronica, trance, psytrance, I am looking for a strong, accurate and fast bass but not at the price of masking low midrange details and with good high frequency extension.
How was the Bryston sound? in one word AMAZING! this is exactly the sound I was searching for. Smooth, detailed, ample and with extraordinary deep, tight and accurate bass. Listening to some of Deadmau5 tracks with the Bryston, was litteraly sublime. I immediatly felt in love with this beast. I never past the 12 o'clock position on the volume knob (with high gain).
But my budget was between $500 to a thousand. I listened to the Bryston before asking the price. I expect it to be around $2000 or something. No, in fact it had a retail of $1295! Wow! There is no way I am turning back to this unit for about $300 over my budget.
I tried my best to convinced James Tanner (a really kind man that seems down to earth) to sell me the prototype at the end of the show. He told me he can't because the prototype have not yet been approved. I told him it was approved by me! But James was really comprehensive about my enthousiasm and he brought me to a Bryston reseller who had a room near Bryston and facilitate the contact with the manager. In a minute, we had an agreement and I will be a futur owner of a Bryston BHA-1. i will link it to my incoming Wyred4sound DAC-2 in balanced configuration. I can't wait
I would like to sincerely thanks James Tanner for his patience (I think I shooked his hand about ten time!) and kindness.
Kudo to Bryston.

Thanks, James, for this quote. As an LCD-2 owner, this is just the kind of assessment of the BHA-1 I have been looking for - one comparing its performance against tube amps and the kind of sound produced on it using the Audeze cans.

Hi Dave,
Yes the BHA-1 seems to be getting great feedback so far.
We have used them at a show in England with Sennheiser and in Montreal with a group of different priced Grado's and of course the headphones that attendees brought with them.

James, Lappy writes that the BHA-1 price will be $1295. Is that now the correct Canadian retail price?
And what is the current estimate on when the units will be shipped?

Hi Dave
Yes $1295 and hope to be shipping worst case the middle of next month. We have a lot of units on order though so any new orders would be a few weeks after we fill the backorders.

Thanks, James. In the past I have bought new Bryston gear without a demo. I have that much faith in it. But over the years I discovered that headphone amps are a whole different animal - I've owned six of them, a couple of which were bought sight unseen. Made a vow the last time to follow your general advice - demo! Therefore, I'm looking forward to taking a test drive when the BHA-1 comes to my town.

Excellent news James, It's been far too long since I've unpacked a new piece of Bryston kit :)
Just hoping I'm in the first batch.

James,
Is there anything that should prevent the user from hooking up multiple sources to the bha-1 at the same time? I'm thinking my turntable for single ended and my cd player for XLR.
Thanks!

No problem - the switch on the front lets you determine which source to listen to.

Hi Folks
Just want to give you an update and an apology. The BHA-1 headphone amp has been a bit of a frustration for us. We finally settled on the circuit we want to use and we built 6 prototypes that we have used at shows and to allow some dealers to demo and to say the least it has been a huge hit.
The good news ( depending on your point of view ) is we are back ordered big time --- the bad news is many of the parts are being built to our spec so we are further behind from our suppliers than I was originally told.
Anyway we should be in production at the end of April and filling orders shortly there after. Again my apology for the delay :duh:

James,
In regards to the final circuit that you settled upon, is it the same one that you used in the prototypes, or did you further refine it?

Hi Folks,
Got this from one of our new dealers that specializes in Headphones and Headphone amps:
"So just spent some time this morning with a few phones on the Bryston. The Audeze LCD-3, Beyerdynamic T1, Fostex TH-900 & because someone asked the UE11pro. I used the same set up from CanFest. PS Audio Perfect Wave Dac w the bridge card as the input, pulling data stream from our HP Media Server. I used Black Dragon Balanced Headphone cable to be consistent on the T1 and LCD-2. The Fostex is not re-cabled as this is not mine and has to go back to Fostex. I used balanced inputs form PWD and balanced output on the LCD-3 and T1. Others where via 1/4" jack.
The LCD-3 and the Bryston are ridiculous together. Just absolutely WOW!!!! I used all types of music. Volume control on the LCD-3 and Fostex where at about 9-11 o'clock depending on original track recording volume. And the T1 was at about 10:30 to 12 o'clock. The T1 and LCD-3 had the most bottom end weight and wow factor. However the Fostex was crisper, not bright just sizzled more. Man do I like the new Fostex. So much level headed across the frequency spectrum over the D7000. So clean. I would say of the 3 it was the best for critical listening. But the LCD-3 was just liquid awesome. So musical....The T1 was no slouch, it is still my vote for best bang for the buck over $1000. All 3 of these phones are fantastic choices for this amp. The great thing about Bryston gear has always been it's neutrality. None of their gear over colors the sound. Always very clean sounding.
So the UE11pro in low gain setting did not exhibit any hiss which usually happens when using such a high sensitivity monitor with a full size amp. The background of the amp is dead quite. I mean darker than dark quiet. There is not a lot of gain flexibility with the IEM but there is no reason you cant use it."

James, I have to say that the BHA-1 has one of the cleanest, if not in fact the cleanest looking internal layouts of any Bryston component. It virtually looks like a mini city with some top notch urban planning. Thumbs up to those engineers!

Question for James Tanner,
Just curious if Bryston has ever thought of manufacturing a dedicated Headphone Amp.
Currently have my B60R in service to clean the volume and selector pots and will most likely trade it in towards a BHA-1.

Like others following this topic for many months, I'm anxiously awaiting the opportunity to hear the BHA-1. The initial impressions coming out of its appearance at shows only heightens the anticipation.
But I was reminded over the last couple of days how much different the headphone experience is from that of listening to speakers. And I emphasize the word "different" to mean precisely that, not better or worse.
I've been into headphones over the past couple of years as an alternate to my main system, having owned in that time three different headphones - Sennheiser HD800s, LCD-2s, and KRK KNS8400s, as well as previously purchased Grado RS-1s, SR80s, and ancient AKGs and Stax - and two different dedicated headphone amps - Grace Designs m902 and Schitt Lyr. My application has been very narrow, however, in that I used the headphones primarily not to wake a sleeping wife in the morning: a vital application if one seeks to maintain domestic tranquility, but narrow nonetheless.
But in pursuit of the headphone experience, I found that a vintage receiver (circa late 1970s) made for an excellent headphone amp. So pleased with that device, I decided to build a second low priced speaker-based system (adding B&W 685 stand mounts), which I discovered produced an excellent sound, without rousing my wife from sleep and, therefore, her ire. But, sadly, the vintage receiver betrayed its age and failed. Bought a Harmon Kardon 3490 receiever as a replacement.
But, in typical audiophile fashion, I wanted a better sound from the second system, especially improved bass extension, again without wife-raising issues. After looking closely at alternatives I decided on the Axiom M80s, which I should receive on Monday.
Pending their arrival, I'm listening this morning to my LCD-2s, via the HK 3490, rediscovering how great they sound - as a headphone experience.
Going through this long, round about voyage, has not dampened my wish to hear the BHA-1, but rather underlined what I should be looking for when eventually I get to demo it: whether it produces a better headphone experience, not whether it sounds better than my upgraded second system, assuming the M80s, as predicted will make for one hell of a second system. Altogether it will have cost, with tax, about $2100, which I believe is a bit less than the price of my LCD-2s plus the estimated price of the BHA-1.
As for my personal preferences, this voyage also has made me come to this conclusion: while the headphone experience can be great for me when I need to use cans or am just in the mood for intimate listening, it is not nearly as satisfying for me in terms of the presence, weight and fullness of music heard via a speaker based system, even when that system includes modestly priced carefully chosen equipment.
Does this mean I will give the BHA-1 a pass? Depends of two things: 1. As James advises, the demo is everything, and 2. How much money I have left after spending a small fortune on my (absurd to non-audipophiles) headphone/second system journey.

Hi Guys,
Just got my BHA-1 yesterday. I opened the box at my reseller's place as his young assistant and him would have like to hear the BHA-1 along with my Audeze LCD-2 (that I brought with me at the store). They put a really quick and basic installation right on the counter of the store consisting of a Cambridge player with balanced cables, the Bryston BHA-1, the Audeze LCD-2 along with my brand new Norn v2 (8 conductors) balanced cable by Norse Audio. They were both really impressed not to say floored by the sound coming from the trio in a balanced set-up from input to output.
The owner who has been in the audio business for more than 30 years told me he never heard better sound coming from headphones before. He was looking at the gears nearly in disbelief. His young assistant was litteraly extatic about his experience. The synergy between the Bryston and Audeze is definitly there. Robust, detailed yet smooth and refined sound with astonishing vocals was the general description.
I am at home right now and I am listening to music with the Bryston and Audeze with my Wyred4Sound DAC-2 linked to my computer with a Wireworld Starlight USB cable as I write this mini-review. I know it's really soon to give a real opinion but the initial impressions are really, really favorables. The sound is so robust, full bodied yet clear, detailed but non fatiguing. Simply great sound from top to bottom. Listening to the incredible voice of Leonard Cohen (accompaniated by magnificent female backvocals along with Hammond organ) in Darkness from his last album Old Ideas is simply amazing! The midrange is all there. Not to upfront and neither laid-back (to my taste at least)
OK, so far so good. The Bryston seems to do everything well (very well in fact) the way it should be but does it have a quality that it is standing out? Yup. The bass slam, definition, depth and control is unheard for me at this point. It's simply amazing. A part of that credit should go to the LCD-2, well known for their bass capabilities but believe me, it's incredibly impressing. I am listening to a lot of electronic music (as right now) and the bass definition and speed are fantastic.It's really close to the physical feeling and experience you can get with a good subwoofer save the lamps rattling and shaking. No kidding.
If you're a LCD-2's owner and you are looking for a suitable amp to unleashe all their fantastic capabilities, I can absolutly recommand the Bryston. At this early stage, I simply can't imagine somebody not beeing happy with this combo.

Simply great sound from top to bottom. Listening to the incredible voice of Leonard Cohen (accompaniated by magnificent female backvocals along with Hammond organ) in Darkness from his last album Old Ideas is simply amazing! The midrange is all there. Not to upfront and neither laid-back (to my taste at least)
OK, so far so good. The Bryston seems to do everything well (very well in fact) the way it should be but does it have a quality that it is standing out? Yup. The bass slam, definition, depth and control is unheard for me at this point. It's simply amazing. A part of that credit should go to the LCD-2, well known for their bass capabilities but believe me, it's incredibly impressing. I am listening to a lot of electronic music (as right now) and the bass definition and speed are fantastic.It's really close to the physical feeling and experience you can get with a good subwoofer save the lamps rattling and shaking. No kidding.
If you're a LCD-2's owner and you are looking for a suitable amp to unleashe all their fantastic capabilities, I can absolutly recommand the Bryston. At this early stage, I simply can't imagine somebody not beeing happy with this combo.

This is very good news for us LCD-2 owners.

Yes, I have to say after reading that I'm seriously thinking that I should audition a pair of LCD-2's to go with my PS1000's once I get my BHA-1.

Now I am tempted! :lol:
Actually I have been planning for it...just waiting for the right moment to strike!! 8)

I had a chance to put the BHA-1 to the test with HD650, HD700, and HD800 headphones at Audio Consultants yesterday. I tested with Bela Fleck and the Flecktones: UFO Tofu and Terry Evans: Blues for Thought, two of my favorite test discs. I had never heard the HD700 before or the Bryston. My ears are still ringing! You know you are having a good time when someone comes by to close the door to the headphone room because you are scaring the normal customers! Yeah it was one of those sessions. This amp is perfect for those phones. It tamed the 650's bass so it was nice and tight and punchy. On the other hand it smoothed out the treble on the HD800 and they sounded better than I've ever heard them.
I compared it to the Pro-ject Headbox SEII and Lehmann Black Cube Linear headphone amps. I switched back and forth between the amps on each track on each CD several times. The cables were single ended. Ultimately I liked the Bryston better than the Lehmann. The Bryston's sound was fuller, richer, more musical and less fatiguing than the Lehmann with all three headphones. I felt like perhaps there was a bit more ambient information being put out by the Lehmann, but it also sounded anemic and unnatural compared to the Bryston.
I never thought a headphone setup could do justice to Victor Wooten's bass, but the Bryston came as close as I've heard to that. With the HD700 and HD800s the experience was more like what I would expect from really good speakers. There was a LOT of synergy between the HD700 and HD800 phones, and neither the HD700 or the Bryston were broken in at all. So I'm sure it will only get better.
The HD650 sounded great too but the other phones were leaps and bounds better. With the Bryston I heard three very distinct levels of performance with those three phones.
I was using a middle of the road source, some very good but not great CD player. At home I'll be feeding it with an Ayre QB-9 at 24/96 material. The Bryston HD800 combo was the best combo I've heard so far. I ordered one. I'll write more when I get it home. :thumb:

I completely agree with all of your findings. I've owned the Senn800 for 2 years now and have tested it with many moderate to expensive electronics and found the Bryston/Sennheiser combo hard to beat.

Hi jimbles,
I have the Grado 1000's as well and as good as the SP-3 headphone section is it is not as good as the BHA-1.
Something I would like to add - I have been looking at headphone measurements and maybe someone can educate me - it seems that the frequency response graphs I have seen are all over the map :scratch: So unlike loudspeakers, headphones seem to have serious flaws when it comes to maintaining an accurate frequency response. I guess that may explain why certain people prefer specific headphones with specific headphone amplifiers :scratch:
I'm all 'ears'

Or this:
http://www.innerfidelity.com/content/headphone-measurement-proceedures-frequency-response
James, I have come to much the same conclusion recently. It seems that correlating headphones subjectively to objective measurements is far behind speakers at present. My take on it is that if one has found a headphone with a "tonal signature" that particularly appeals then it may be best to search for similar next time around.
I assume you're aware that you can plot multiple phones against each other on www.headphone.com. Here is an example with my current HD650s and a (cheaper) Grado phone that is probably representative of my first "serious" headphone some number of years ago. Coming from speaker measurements, it would be hard if not impossible to know which one might prefer from these curves:

I have had little experience with headphones and that little mainly consists of listening on Sennheiser HD 650s via the headphone jack of my BP 26 (which is fed by a BDP-1/BDA-1 combination. Never having used a dedicated headphone amp, I am curious as to how much of a difference an amp such as the BHA-1 would make (in very general terms!) using the same HD 650s. Any advice would be appreciated.

Hi Folks,
I compared the $1295 Bryston BHA-1 Headphone amp to the $3250 hybrid tube/chip Cavalli Liquid Fire last Sunday at a meet.
Bryston BHA-1 vs Liquid Fire (with HD800 off the Calyx DAC, Bryston using balanced, Liquid Fire on unbalanced, 800s on Bryston using balanced output.
The main attraction for me, seeing just where this Bryston stood among the Head-fi elite. What does a speaker amp maker know about headphones? Apparently plenty. Coming into this comparison I knew my tastes lately have been for more neutral, slightly biting/attacking, crisp, clean sound, and with Bryston's reputation for these attributes in the speaker world, I thought this BHA-1 was a sure thing.
After roughly volume matching the two, I started paying attention with the Bryston going first. I've had this pairing of HD800 and amp for a couple weeks, but the DAC was new in the chain so I wanted to get my bearings. Oddly the sound didn't seem all the much different than what I remembered from the Bifrost, but we didn't compare the DACs side by side so I can't be sure. I picked up the expected bite and extreme resolution from this pairing and readied myself for the Liquid Fire change off. Right away the Liquid Fire was a completely different sound. People who say amps make no difference in sound have no clue what they are talking about. The Liquid Fire impressed right away with it's smooth flowing sound that luls you in and relaxes you. At first, coming from the Bryston, I panicked, thinking.. the Liquid Fire is way better(!), but as I listened more, I could tell the accuracy is not what I'm used to. Things like birds flying across the stage sounded like a recording not as if they were really there like I hear with the Bryston. Detail was slightly smeared, and on the whole I started feeling less in the music/sounds, and more bored. The Liquid Fire was playing music at me, not taking me along for the ride.
Back on the Bryston, I hear the detail pushing the edge almost to harshness, but not quite. Exactly as I want it. Travis commented that certain passages with the Bryston were just too energetic and he couldn't accept that for his enjoyment. I can certainly see where he is coming from, but that rawness, when paired with an ultra clean headphone like the HD800 is really majestic, IMO. Bass seemed rather similar between the amps, no difference in volume I could detect, perhaps a slight warming from the Liquid Fire, but it was negligible. Soundstage and imaging edge goes to the Bryston easily. A marble (or something like it) effect used on a BT recording tracked left to right and right to left precisely on the Bryston, where there was some slight gap in the middle on the Liquid Fire. I think the Fire did better with meshing images in front of the listener, though, and with it's smaller soundstage brings sound sources together and blends them nicely with it's creamier presentation. Large wide tracked effects were a delight with the Bryston. Massive, but precise soundstage with the HD800 paired along with it put everything in place from very intimately near to very distant and all in between.
Orchestral music is as best as I've heard, short of playing in the orchestra myself, with this pairing.
I have no desire to buy anything else, which is shocking.

I had the chance this weekend to go to Audio Consultants in Evanston, IL and listen to the BHA-1/Sennheiser HD800 combo. Wow! Just ridiculously good. Last time I heard the HD800 was also at Audio Consultants, and I remember being sorely disappointed by the lack of bass response and the resulting shrill highs. The massive power of the BHA-1 just opened up these headphones and made them sing in a way that I've never heard before. About 12 o'clock on low gain and 10 o'clock on high gain were enough to put the headphones at a pretty loud level. There is an incredible synergy between the BHA-1 and the HD800. I was floored by the BHA-1's ability to resolve details against a jet-black background. I think that a higher-quality source would have made the experience even better. I listened with the Micromega CD player that they already had hooked up. It's a pretty good player, but I know that there are better sources for not significantly more money.
I've been searching for quite some time now for a headphone and amplifier combo that would satisfy my desire to be in the upper echelon of audio without having to take out a second mortgage. I've found it with this pairing. Bryston is going to have many of the boutique manufacturers of headphone amplifiers running scared because the sound quality of this amp is as good as they come and it costs about 1/3 of what some other companies charge for their amps.
James, just a quick question about the gain switch? Is the gain switch supposed to be used essentially as a volume control, like, if I can't get enough volume on low gain, then switch to high gain? Or should I be choosing low gain or high gain based upon the nominal impedance of the headphone, like, every headphone below 100 ohms should be set to low gain, and every headphone above 100 ohms should be set to high gain? (I'm just making up these numbers.) Thanks!

Hi
Glad you enjoyed the BHA :thumb:
The gain setting is more like a volume control in that the more inefficient headphones will need more gain that the more sensitive headphones. The impedances seem to corrolate to the higher and lower impedances settings as well but I would make the decision based on comfortable listening levels.
The volume control is designed to have a wide gain variation from say 9 o'clock to 2 o'clock and the BHA runs pure Class-A so using the volume control at say 12 o'clock on the low gain setting will probably give a lower noise floor than using higher gain setting at 10 o'clock.

This is the setup I heard at Audio Consultants as well and I concur with these conclusions. The amp is killer with the HD800s. The amp they usually have set up there is either the Pro-Ject Headbox SE (or more recently SEII, which I own) and the Lehmann Linear. The Pro-Ject amps can be shrill, so that may explain your previous experience with those headphones.

Can I ask? Was a result like "There is an incredible synergy between the BHA-1 and the HD800" accomplished by "voicing" the BHA-1 for the HD800 or similar? Or was a more "open loop" engineering process followed?
-
Maybe I've been a little unfair on the HD-800's in the past, I've heard them on a various selection of amps but the 800's have always left me a little cold, maybe it is time to revisit them again with the BHA-1.
So come on James, stop teasing me, any idea when a shipment is going to hit the UK?

This may help someone (from innerfidelity.com):
Headphone acoustics are significantly different than room acoustics because you are using an acoustic coupler as opposed to propagating the sound through free-space - technically called the “free field” in audio terminology, and defined as three-dimensional space where there are no reflecting surfaces. When measuring speakers, you measure the sound out in the free field with a reference microphone and assume if the sound measures flat, you’ll hear it as flat if you put your head where the microphone was --- which is true. But with headphones, there is no free field in which to measure the sound. Due to reflections and modal oscillations within the enclosed volume between the headphones and your ear, the sound at any particular point within that space may be different than the sound at another point. As a result, the only legitimate place to measure the sound from headphones is at the eardrum.
That’s a problem because if the sound is flat out in the free field and you stick your head in it, the sound is no longer flat by the time it hits your eardrum. This difference between flat sound in the free field, and the EQ of the sound you hear at the eardrum when you stick your head in the sound in the free field, is called the Head Related Transfer Function.
(http://www.innerfidelity.com/images/110401_measure_graph_headacousticshrtf.jpg)
The image above shows the independent of direction Head Related Transfer Function of the Head Acoustics HMSII.3 head acoustics simulator.
Multiple things come into play that effect the EQ of the sound reaching your eardrum:
Your chest and head volume provide some acoustic gain at mid-frequencies.
Between 2000Hz and 5000Hz the concha (the little cup in your outer ear around the entrance to your ear canal) acts as a focusing dish to get sound into your ear canals, and as a result provides some significant gain to the signal at these frequencies.
The length of the ear canal provides opportunity for modal artifacts; typically peaks at 3kHz, 9kHz, and 15kHz roughly, depending on the exact size and shape of the ear.
Flat sound in the free field is not flat by the time it gets to your eardrum.
This is the frequency response measurement sheet that came with my LCD-2 headphones showing the HRTF compensation:

Most recently, My Bottlehead SEX 2.1. (for sale if anyone is interested)
The 2 amps are close, but the Bryston pulls ahead with a bit more detail. The soundstage is also a little wider due to the ability to used a balanced signal all the way from the source to the headphones (yes I tried a single ended path too).
The Bottlehead might have a bit of an advantage in bass power when running the power hungry HiFiMan phones as it puts out 2 wpc. I'll need to run a comparison again once the Bryston gets some more hours on it.

Quite interesting. For whatever reason, ordering the BHA-1 has motivated me to learn more about the technical aspects of headphone listening instead of only focusing on 2 channel speaker setups and room treatments. I never gave much thought as to how your ears can and do amplify specific frequencies and I had never heard of HRTF.

Is it easy to convert over to balanced? I've got a pair of Grado PS1000's, if it offers a further improvemnt with balanced it is definately something I will have to look into.
Even though I've had my BHA-1 on order for what seems like an age I'm going to get my first listen on Monday over at PMC here in the UK so I'll take my Grado's along, see how it compares to the headphone out from my SP3.

Will the UK distributors being doing this over here on their behalf?

It depends on the headphones. If all 4 wires are carried to the plug, then it's easy to cut off the 1/4" plug and install a 4 pin or 2 - 3 pin XLR plugs.
Unfortunately, the last Grado's that I looked at had the grounds connected where the cable splits which only leaves you 3 wires at the plug. In that case, the headphones would need a complete re-wire.

There are quite a few 3rd party replacement headphone cables available (Cardas is just one), just google it.
A number of companies offer this service but they're all in the US.
PMC could do it over in the UK or maybe some new fledgling Bryston dealer perhaps?

Well at long last at a Bryston day at PMC on Monday I actually got to hear the BHA-1, I couldn't resist taking a picture -
(http://www.audiocircle.com/image.php?id=65394)
To say I was impressed was an understatement, I'm so used to my Grado PS1000's using the SP3 headphone out, which sounds fantastic, but I really wasn't prepared for how much better they were going to sound using the BHA-1, basically the Grado's just came alive, it does make you wonder how many people own good headphones and never unlock their true potential.
Using the BHA-1 just gave more drive at the bottom end, but kept the control so the bass was tight, powerful and detailed, but for me it was the mid/treble that just went on to another level, I know the Grado's are good and I'd heard them described before as the only Dynamic headphone to take the battle to Stax but on previous comparisons I still felt that the Stax headphones had the edge with overall detail and clarity, I'd love to do that comparison again now using the BHA-1 to drive the PS's as I was amazed how much cleaner the presentation was and the overall insight into the recording, I feel that the BHA-1 was really driving the Grado's to their max, obviously I'd have loved to have spent longer with the BHA-1 to get a 100% conclusion but early impressions are looking extremely favorable .
I had to wait a long time to get to hear the BHA-1 and it certainly did not disappoint, another high class product from Bryston, the only problem I can see is that I'm still waiting for mine, come on James get another shipment over to the UK asap :)

Hi James,
Im lining up for the BHA1, but still need some advice. Since I'd want to position the BHA near my favorite chair (that is not very close to my main setup) I'd want to opt for the balanced connection. My Bp26 balanced out is in use... How do I proceed? Ive got the tape out you mentioned before, or could use the second RCA out, but the latter is contrary to your advice I believe. the former already in use...
Is there some modification I could opt for, or would I have to wait for the Bp27 that would have a second balanced out? or a balanced tape loop of sorts?
I feel a bit in limbo here, so please help me out.
Marius
Ps wouldn't dare to ask for headphone advice. (but still do of course, the lcd2 or 3, sennheiser 800, hifiman and beyer dynamics t1 on my shortlist. Stax I would really want to consider, but then I would have to forgo on the BHA1, so not an option....)
-
Hey Marius, you could get one of these.

that looks really good, thank you Terry.
I'll note that as option 1. (maybe James adds to this option too?)

I've never heard the Beyer so can't comment on those, but of the rest I would go for the Stax, best sound by far of the ones you mention, then the LCD3, LCD2, Hifiman then finally the Sennheiser.
I gave the Stax SR-507, there again if you want the best, you'll regret if you listen to the Stax SR009. Once you've heard then you just need them! (They're quite expensive!)
Start off with a cheap driver then you can always upgade later.

Hi Marius,
I use the Tape Out from my BP26 to my BHA-1 but it is only a meter or so. The advantage of that is no volume control and a fixed output.

Tape out is the best route otherwise if you use the pre out you'll end up with two volume controls in your circuit

I guess it would depend on the distance, currently I have my head-amp (B60) behind the sofa so I'm running a 30' of unbalanced cable which picks up a bit noise, my 4BSST now gets the balanced connections from the BP25P. But when I get my hands on a BHA-1 I will definitely take advantage of the balanced connections for the headphone set-up and run the 4B single ended. :D

I have the same problem when my unit arrives. Do I use RCA's to BHA or do I just disconnect the balanced cables from the BDA or BCD. My balanced headphone cables are 6 feet so I'll sit next to the system.

Hi James
Is there no balanced option? What was the design choice for the balanced in on the bha1 then? I understand the volume and fixed output issue, but am
I right assuming you designed the bha1 without the bp26 in mind then? And linking it to a source component directly? Maybe the bda1? Would have to miss the record player only in that architecture, which would be a great miss though ...

Yes the BP26 was really not part of the design concept when it came to a balanced source - should have thought of that :duh: The BDA-1 would be a good source component.

I got my hands on some old favorites, Sennheiser 600 & 650.
Plugged in single ended, I was surprised that these used to be my favorite headphones. Kind of disappointing compared to the Hifiman 500 phones
I still had a balanced Sennheiser cable, lying around, so I hooked it up......
What a shock!
It was amazing how much the Sennhieser's improved simply by driving them with a balanced signal.
-
Have a balanced "pass-through" output associated with the BHA-1 balanced input. This way you can mate the unit with a balanced preamp or integrated without the need for physically switching or splitting the XLR cables when listenning to your audio system.

James,
I have been assuming all along that the BHA-1 would take balanced inputs from the BDA-1 balanced outputs. But since I use the BDA-1 balanced outputs to my BP26 balanced inputs, and my BHA-1 unbalanced outputs to a second system, that leaves me with the same kind of limitations being discussed here as I understand them. It is one of the (trivial) reasons I have been hesitating about the BHA-1.
So I have these questions:
1. Am I correct in assuming that a balanced Y cable would allow me to output from my BDA-1 to both my BP26 and a BHA-1?
2. I would have no immediate intention to get balanced cables for my LCD-2, so I would be using the simple RCA jack for output from the BHA-1 to my headphones. The question, then, is there any advantage to use balanced cabling into to a BHA-1 if you are not going to use balanced cables from the BHA-1 to your headphones?

HI James,
problem still is I would like to listen to my record-player through the BHA1.... if I'd use my BDA1 's balanced outs I'd have to use those Y-cables, but I would have to be without all the analog sources. would there be no option to make modifications to the BP26, so that I could have a balanced signal to the BHA1 without volume control in the signal path? I suspect more owners of the bp26 would love that. Especially those that invested in the BP1.5 (like me...)

I will ask engineering but I doubt it as our balanced circuits are fully discrete class A and therefor would be a redesign.
James
-
The examples provided clearly indicate the benefits of "Pass-through" (No-gain/volume) designs in components where their inclusion offers improved flexibilty with regard to the integration of a high quality balanced headphone system, such as the BHA-1. In a situation such as mine, a high-quality digital source can be routed properly to both the BHA-1 and a balanced Integrated amp without the need for a performance-limiting "Y" connection compromising the performance of a top-grade balanced interconnect. I would much prefer the sonic integrity of a direct connection to the BHA-1, outputed balanced / without gain to my integrated amp as opposed to a split to both. I am confident that any BDA-1 owner with an associated top-shelf Integrated and interconnect would prefer this also.
-
Since the BDA-1 is upgrading its USB resolution why not reducing 1 BNC and 1 RCA inputs and add another pair of balance out??
-
No please.... Already short of inputs on the Bda.... It would seem more adequate to update bp26 with balanced And unbalanced passtrough. That way all the other analog sources could be enjoyed over the bha1 and the tape/source could keep its designed function. As a tape monitor.
Or have the bha1 have a tape loop , but James repeatedly stated that was not in the works, when the bha1 was on the drawing table....

Maybe you should consider moving over to the UK, we don't do heatwaves, that way the BHA-1 would be a keeper :wink:
I feel for you though, couldn't have been an easy decision.
I'm still waiting for mine to make it over the pond and already there is one on the classifieds, crazy :|

From http://bryston.com/products/headphone_amps/BHA-1.html
"Features: 10k input impedance"
What's the advantage of such a low impedance?
Could there be any drawback, whatever?
... e.g.: Naim specifies 50k http://www.naimaudio.com/hifi-products/pdt-type/165 (http://www.naimaudio.com/hifi-products/pdt-type/165)
Why not 47k ? ...isn't this value a Standard?
Inquiring minds want to know ...
:)
-
High impedance pots will be affected by cable capacitance earlier than low impedance ( 10K) pots. It's just physics ! So with long capacitive cable you could have audible HF roll off. In this situation a 10K pot could possibly get away without a problem.
On the other hand some preamps or sources might be happy with high impedance loads ( especially tube preamps.......not all of them !). Solid state preamps can easily handle low impedance loads within reason.
High impedance pots (high input impedance circuits) also are more easily prone to noise pickup. But I prefer high impedance inputs , I prefer the sound I hear. But then everyone has his or her own personal likes and dislikes.
There is no audible difference between 50K and 47 K. 47 K is one of the standard values for resistors caps etc, but 50 K pots are common and it doesn't matter if they are higher or lower like 45K or 55k !
Most often you see 50 K on tube circuits and 10 K on ss circuits.

Hi, after I have now enjoyed my GamuT Di150 and Phi7s with a BDP and BDA, it's time for me to go headphones and I am eagerly waiting for my BHA. Europe is on the tail end of shipments, I think. I have read through the entire thread here and was thinking back and forth between a Grado GS1000i and Audez'e LCD-2...until I came across a Sennheiser HD800. Anybody got any experience, opinion, reco? Intend to connect the BHA balanced to the GamuT (yes, two volume controls unfortunately) and would use the HD800, that has exchangeable cables, with a balanced 4-pin stereo into the BHA. Since here was so much talk about Grados & Audez'es, hope anybody has a view on the HD800s. Appreciate.

Hi,
Yes it has caught me a little off guard.
When I did the research on Headphone amplifiers I got the feeling that there was almost an arbitrary synergy between a specific headphone and a mating headphone amplifier. I thought maybe a headphone amp (Bryston) designed to be as sonically neutral as possible may not fly :duh:
Obviously I misjudged the market.

In preparation for my BHA-1 arriving, surely it can't be much longer eh James? and the opening of my store, all my demo Grado's turned up today, also opened a HiFiMan account so I can demo the BHA-1 with the HE-6's, also got a Stax account, arguably the best headphones on the planet, so it will be interesting to try the PS1000's/HE-6's with the BHA-1 against a similar Stax system, would also love to get a Senheiser and Audeze on board as I've decided to have a dedicated Headphone room, but first I need to get some coffers back into the account :roll:
I have to say though it is great fun being able to buy all this great kit under the disguise of business :wink:

Hi Terry,
Found out yesterday after talking to the HiFiMan rep that there is a huge headphone show 20 mins away from me in Cambridge on September 15th.
http://www.head-fi.org/t/601003/uk-2012-head-fi-meet-september-15th-cambridgeshire
Huge list of equipment on Demo, no sign of the BHA-1 though, maybe worth coming over with one James :wink:
Personally I'm gutted as I'm at the Goodwood Revival Meeting that day otherwise I would have been there in a flash.
Btw, Terry, it's all your fault I've been chasing a Stax account, hoping to have the SR-507's and SR-007's on demo :)

Nice Greg, I'm not jealous, honest :)
The LCD-2's are the only headphone that I have not listened to yet that I'm really keen to, along with the LCD-3 of course, Audeze just don't seem to be very well represented over here in the UK.

Regarding Audeze, see my email earlier about Silverstone/Whittlebury.
No 009's then?
You'll need 3rd party Stax energisers next

As for Audeze, just got their UK Distribution no, maybe worth a call, saying that I think I'll go to Whittlebury and have a listen 1st.

Vipers - there are no Audeze dealers in our state and I purchased the LCD-2's without hearing them first. They are easily my favorite headphones of the five I have purchased over the last few years (Bose QC2, Sennheiser 545, Beyerdynamic DT880 & DT990). The BHA-1 drives the LCD-2's easily. Coming from the BDA-1 and using the 4 pin balanced connection I have the BHA-1's volume between 8-11 o'clock. Coming from our cable TV box the BHA-1 volume level is from 9 to 12 o'clock. I am using the low gain setting on the BHA-1.
I should mention that I am not a big headphone guy in general - I prefer listening to my 2 channel setup for music. I just wanted something that is closer to the audio quality of my main system for our bedroom that won't wake my wife up. The Audeze/Bryston BHA-1 setup does that and in some ways exceeds my main system (wasn't expecting that). I was a bit worried the LCD-2's would bother her since they are open - so far they haven't. I actually think I am finished buying headphone gear.

how long is the balanced cable exactly?
thank you,
al.

Thanks al. The balanced cables are 90' (27.43 meters) long. They are made with Mogami W3173 wire and Switchcraft XLR's.
The distance from the upstairs bedroom's BHA-1 to the downstairs family room's BDA-1 was approximately 77' (23.4 m), but I wanted to have extra cable just in case. Routing the cables was the tough part, but it was worth it.

Hi James,
I seem to remember reading a post from you on this thread (or possibly the equivalent thread on Audio Aficionado) in which you stated that Bryston is considering the possibility of adding some additional features, like additional inputs and outputs, to the BHA-1 so that it could essentially function as a preamp. (Unfortunately, I can't find the relevant post.) Is any more consideration being given to this idea? If so, what would be the timetable for this product to be released? What sorts of features are being considered?
Thanks!

Hi
Yes we thought that adding a pair of Balanced outputs on the back would allow the BHA to be a preamp as well. We will have to increase the price though so unless it is a desirable option for most we may have to look at it as an additional option rather than a standard feature.

Thanks for your response, James. I definitely understand that this would increase the price, but, at least to me, this is a highly desirable option. It would be cool if this could at least be available as an additional option for those who want it.

could you please explain a bit more what the balanced outs in the BHA would put out? How would this work: source:BHA:poweramp? How would we get all analog sources into the BHA then? Or would this be a complete replacement for the BP26?
Maybe I should formulate it the other way round: how would I get all my sources that pass through the bp26 into the 10bsub/28b's, into the BHA, without interfering my current setup?

bummer. :cry:
could you please explain a bit more what the balanced outs in the BHA would put out? How would this work: source:BHA:poweramp? How would we get all analog sources into the BHA then? Or would this be a complete replacement for the BP26?
Maybe I should formulate it the other way round: how would I get all my sources that pass through the bp26 into the 10bsub/28b's, into the BHA, without interfering my current setup?
Thanks,
Marius
Hi,
Use the Tape Outs on the BP26 to the RCA ins on the BHA.

Hi,
We can do it now as a special order I am told.

James, this is great news! I'll definitely get this when the time comes for me to order a BHA-1. Would I still be able to order this through my local dealer, or is the ordering process different for special orders?

Through the normal dealer is fine.

I am in possession of the amp, finally! I will post impressions tonight. My dealer also loaned me a balanced cable for my HD600s so I can test it single and balanced. Basically it is just a stock HD600 cable with an XLR.
I have a great setup but unfortunately my headphones are not the best. The HD600s are good but have limitations. I do not expect miracles but I do expect an improvement. This is to the lay the groundwork for better cans, probably the Grado PS1000s.
I also picked up the Ayre break-in disc so I will be running glide tones and brown noise through the amp while I am at work to speed up the break-in process, although the one I heard in store sounded GREAT right out of the box. Fortunately, my fiancee is out of town for a week and then we are meeting up for a little vacation so I'll be able to run some nasty break in noise through this thing 24-7 for at least 100 hours. And of course when I am not breaking it in or listening to music I'll be playing Battlefield 3 so I will break it in with the (hopefully blissfully enhanced ) sound of mortars, machine guns, and screaming jet engines!
Oh yes, this week is WIN.

To make a long story short, the amp is great out of the box and phenomenal after 48+ hours of intense break in. It is getting better all the time. Oh and I decided that my HD600 just wasn't doing this amp justice so I went back and picked up a set of Grado PS1000s. Both of those items now occupy permanent positions in my listening room.
This unit is first rate, James. The more I play it, the more I like it. Many thanks to Bryston, Grado, and the knowledgeable and accommodating folks at Audio Consultants in Evanston, Illinois for setting me up with the best headphone setup I have ever heard!
I can tell both the amp and the headphones are true audiophile products and will scale as I upgraded sources, cables, and find higher quality source material. I will have this one for a long, long time. Cheers! :beer:

Very interesting, James. It seems that for some users, like me, it could work out well as a possible preamp upgrade since I use only two sources.
But that raises this question: how would the BHA-1, used as a preamp, in terms of performance, compare to preamps you might introduce based on the outstanding preamp section on the SP3?
Dave

...this is certainly a very nice upgrade! well done, Bryston :thumb:

This is very interesting.
How would the BHA-1 compare in performance as a preamp to the BP6 and 26 preamps? Would it be the same level of transparency, output voltage etc?
Will there be a ne brochure and spec sheet out shortly?

Hi,
It has a bit more output (voltage/current) available because it was designed to drive difficult low impedance headphones so it will be interesting to get the feedback on what our customers think of the sound when used as a preamp.

Hi,
I do not think so as it would mean a circuit board change.

HI James,
Is it possible to have the BHA1 received balanced input (in my case from the BDA1) and the unbalanced sources via the Tape outs on the BP26, and then select inputs on the front of the BHA1?
Would this be useful (being a full balanced circuit, form source to output), or would you just advice to listen to the balanced sources through the Tape out too, that obviously pass there?
Since I believe to may have deduced from other fora on AC that playing a Balanced Headphone would be the way to go, Im trying to figure out how to end up with the optimal setup: best electronics for all sources, both balanced and not.
Thanks!

Hi Marius
Yes you can set up the system as you describe with the balanced out of the BDA to the Balanced in on the BHA.
James
-
HI James,
Thanks, just to be 100% certain before ordering: so balanced and unbalanced sources can be used simultaneously, and independently selected with the little input-selector on the BHA? In fact just like the BP26 source selection works? As opposed to the input-selection switch on the Bp1.5, where either MC or MM can be accommodated, but only 1 at a time in 1 setup)

Hi Marius,
Correct - the source select determines which input signal gets sent to the front panel outputs.

thank you sir, wonderful :thumb:
I take it the selected source gets sent to the newly added back panel outs too...

So, the back panel outputs are just a parallel connection of the front panel balanced headphone outputs?

MEMO: To All Bryston Customers
SUBJECT: Customer Feedback BHA-1 Headphone Amplifier
DATE: August 2012
Hi Folks,
The following are some comments of some “HEADFIERS” regarding the Bryston BHA-1 Headphone Amplifier and some of the most difficult to drive headphones out there.
james
“Some headfiers and myself, had a meet at my workplace last Saturday.
I had the chance to try the Audeze LCD-3 with the BHA-1. It was a really good synergy and some of the attendees thought it was the best match-up of the day. I compared the LCD-3 and LCD-2.2 for a couple of minutes. The sound signature of both headphones is really similar but the LCD-3 bested the LCD-2.2 in all areas except bass slam and fun factor. They were more refined and textured than the 2.2. I sure can live with the 3 easily but after a comparison of the two, I feel no rush to go buy a pair of LCD-3. I still love my LCD-2.2 (especially with my taste for electronic music). But the LCD-3 are definitely a superior headphone for musicality and accuracy.
BUT, the biggest surprise of the meet, was when we tried the Hifiman (insanely hard to drive) HE-6 with the Bryston. Absolutely everybody who listened to this combo, were blown away by it's musicality and sense of realism. Yes we had to push the Bryston to it's power limits on most songs but the results were nothing short of spectacular. I prefered the Hifiman to the LCD-3 by a nose. I would like to have the chance to demo them for a much longer session on my Bryston (Benjamin?). Even the owner of the HE-6, Benjamin, said that he finally discovered the full potential of the HE-6 for the first time. And he feeds the HE-6 with the supposedly matching Hifiman EF-6 headphone amp. He was thinking of selling the HE-6 but after hearing them with the Bryston he is now considering of selling the EF-6 amp and looking for a Bryston BHA-1.
The BHA-1 and HE-6, are really, really an impressive combo.”

That last paragraph has got me rather excited as I spoke to the HiFiman rep again in the week regarding being a stockist, he is very cautious at the moment about who he signs as a dealer as he has only just taken on the account himself, I think I may have to send him a copy of that message as with the BHA-1 on demo it would be great to have it paired with the HE-6's, well that is if my BHA-1 ever arrives, eh James :wink:
-
Dear all,
I just received my BHA-1 2 days ago.
People who know me know that I am not someone given to exaggeration. I am not usually dramatic about situations. I tend to be fairly rational and analytical when it comes to many situations. And my initial listening impression of this headphone amp fresh out-of-the-box: Wow!
Headphones used: Hifiman HE-6 (balanced terminated with a 4-pin XLR using the stock cable)
Source: an inexpensive NAD C542 CD Player
Interconnects: an inexpensive Belden 1505F cable with Canare RCA plugs (singled-ended)
Power cord: stock power cords which come supplied with equipment
Even with the above inexpensive set-up, I was able to have the best sound I have ever experienced from my HE-6.
I am not good with descriptions using hifi speak so please pardon me. I read hifi magazines and have been lurking in hifi forums for years and I still do not know what some of the commonly used jargons mean precisely. So I shall use a very layman approach to describe what I hear: the HE-6/BHA-1 combination allowed me to hear deep into the recordings.
I listen mostly to classical music, from large scale orchestral works to chamber music. Treble was crystal clear (in some orchestral recordings, the sound of the triangle - emerging from the back of the orchestra - lingered on for quite a while). Bass was solid, weighty and tight. Orchestral tuttis were 'big' (for lack of a better word). The soundstage was wide and gave the illusion of it extending well beyond the headphones. Solo piano tones were very beautiful. Recorded solo violins didn't sound shrill at all (and when miked closely enough, I could actually hear into the 'timbre' of the bow coming into contact with the strings - does this make sense?). Mass and solo string pizzicatos were very crisp.
A bit of history....
Before the BHA-1 was officially released, I had some correspondence with James Tanner through E-mail and also through this forum with regard to its expected driving capability for some of the more hard-to-drive headphones. In particular, I was concerned that the BHA-1 would not be powerful enough to drive the HE-6. In fact, I was so certain - although sight unseen, sound unheard - it WOULD NOT be powerful enough to drive the HE-6 that I went ahead to buy the less 'demanding' HE-500 (the second model in Hifiman's planar series) in preparation for the arrival of the (long-overdue) BHA-1.
Well, after my initial listening impressions, I can now breathe easy...(and end up with an additional pair of headphones I don't really need)
(For those interested, I set the BHA-1 to 'high gain' and use single-ended RCA input from my source. Depending on the recording level of the source material, my volume knob positions on the BHA-1 range from 9 o'clock to 11 o'clock. If I turn up my volume knob any more, the music becomes excessively loud and I risk damaging my hearing)
I have learned from this experience that my perception of things is often coloured, and unneeded paranoia caused, by people's impressions as posted on the forums. I pre-judge things too definitvely. I somehow got the impression from hearsay that the BHA-1 would not be able to sufficently drive the HE-6. "HE-6 needs a speaker amp to drive it optimally", so some say. That impression is now thrown out of the window, based on my own experience. The bottom line is, whenever possible - and I understand that it's not always possible or convenient - we should always listen to the gear ourselves and form our own (hopefully not too subjective) opinions.
The HE-6/BHA-1 are a great match.

Hi James,
Final question before ordering: would there be any advantage sonically in using my external power MPS-2 with the BHA1 because of elimination of power-noise? Any pricing consequences?
I would need a longer power cable than the stock one, so please take that into consideration?
(forgive me not reading through the whole thread again, I seem te remember a previous discussion about this, but can not find it anymore. sorry)
if there are any other special order options, could you list those please?

Hi Marius,
I would not go with the external power supply version. In fact i am thinking of dropping that option. There is no performance advantage and I think it limits the resale ability of the BHA as well as prevents you using it in other systems or rooms in your home.
Make sure you get the latest unit with the Balanced rear outputs.
james
-
Thanks, always appreciate an honest VP!
If I order one this week, it will be the latest with the rear balanced outputs? My dealer won;t have a stock BHA1 i suppose.

Dear James,
Was just wondering. Am the happy owner of a B100 integrated. If I were to buy the headphone amp (which I am considering for my Grado GS1000's), would I be able to use the preamp part of the BHA-1 and connect it to the poweramp in (after using the switch), or does it only come with balanced outputs.
If it is possible, do you think I would get a noticeable inprovement of the sound quality?
If not I would "need" to trade the B100 for a 4BSST2, which would have the advantage of the fully balanced connection. One would assume this would be a major step forward soundwise. As the B100 is some 200 euro's more expensive I might even get a good deal, but that obviously depends on the local dealer. As I am also (still) considering the BDP/BDA combo, we just might be able to work out a deal that would make everyone happy.
Cheers,
Bob
-
Hi Bob,
Yes BHA only comes with balanced outputs as all the others on the rear panel are inputs.
You could use the Tape Outs (RCA) from the B100 into the BHA-1 RCA ins and that way anything you play on the B100 gets directed to the BHA
james
-
Thank you James,
My issue would be that I would like to profit from the pre-amp section of the headphone amp, which you seemed very enthusiastic about and the balanced connection.
Would the: BHA-1 > balanced > B4 SST2 be an audible improvement over the B100, or should I just stick with that?
Bob

Hi folks,
Trying to pin down my next audio audnirvana, i started to investigate the balanced headphone definitions, and ways to realize that. Source Balanced out/BHA1/Balanced headphone . The last stage seems to confuse me, under the impression to have read that some Headphones have to be recabled to be able to use them balanced mode. Talking about the Sennheiser 800, Audeze 2 or Beyer T1, Hifiman seems a bit difficult to get overhere.
But then I read that the Headphones with detachable cables like the Sennheiser I would just have to change the external cable and be set? Is it really just that easy? Would be wonderful of course . really no internal wiring changes necessary?
Second question coming out of that is what cable to uses then. I love a good cable, http://www.headphone.com/accessories/cablepro-hd800-balanced-headphone-cable---10ft.php but 650 $ or more for 3 meters balanced cable seems a bit steep. Cheapest I could find was this Cardas http://www.headphone.com/accessories/cardas-balanced-cable-for-hd800-10ft-neutrik.php, but it looks a bit 'handmade' to be honest. What to buy? Does Bryston make some?
"The (stock HD800) cable is balanced as standard, so all you have to do is to cut off the jack plug and replace it with the balanced connector(s) of your choice." is it that simple?
As not all my sources are balanced (Phone and Tuner as most relevant) I do want to connect the RCA outs of my BP26 tape to the RCA ins on the BHA1. James confirmed this is possible simultaneously. I need some feedback please about playing these analog sources through a balanced connected headphone. There would be no noise/humm or other issues?
Thanks!
Marius

Hi Marius,
I personally think that Hifiman headphones (esp. the HE-6 and HE-500) are worth hunting down. Of course the other headphones you mention are also great and each has a loyal following.
There are many balanced cable suppliers, each claiming superiority over the others. Among the popular ones among users of www.head-fi.org are:
1) Toxic Cables (www.toxic-cables.co.uk)
2) Q Audio (www.q-audio.com)
3) Moon Audio (www.moon-audio.com)
I am not affiliated with any of the above.
When I connected the BHA-1 to the 'Tape Out' of the BP-26, running a pair of Hifiman HE-6, there was no detectable noise or hum, with or without music.

Marius - good to see you back in the headphone world.
I would say - stay away from cards - there are better cables in the market.
You may want to look into used market or ask virtue audio to make you a balanced to RCA dongle and see how things go before making the plunge.
Cables need to be matched with the headphone and gear ... Be sure to talk wit someone who has experience with various cables and headphone matching with them ...
Moon audio makes a great cable but I had a couple of less than desirable experiences that I took my business elsewhere ...
Good luck

Marius
Hi Marius
Just after market single ended cables not balanced yet ...
... Cardas clear seems like a great choice - did not know they offered clear option for headphones ... Shows how behind I am on the headphones after market cabling experiences ;)
The bottom Line is the cable has to match your system - phones and amp along with your listening preferences ...
I had silver dragon on akg701 and it was a great combo on both solid state and tube amps and gave akg1000 run for the money on woo audio 5
I have the he500 with Milan acoustics cable (thank goodness it did not sell) I am waiting to move to our new house before I decide on the headphone setup ...
Hd800 are more sensitive to cabling and amp than perhaps any other phone - so be sure to talk to a couple of people and ideally look for experiences on head-fi - people who have hd800 and after market Cale and over the honey-moon period and no longer feel that their phone is the best in the world :lol:

Hi All,
Please help: BHA1 is on its way, as is the HD800. Balanced cable is last point of investigation. The local Sennheiser dealer told me he failed to understand how a stock Sennheiser cable (4 wires) could be made into a balanced cable (3 left, 3 right) by cutting of the stock Jack and substitute that with 2 3-pins male xlr. Could anyone here point me in the right direction?
Ive found this, but since it is for the Audeze LCD2, would that be to Brystons definition of correct wiring too?:
www.headphiles.org/index.php?topic=1919.0
(http://i192.photobucket.com/albums/z21/blackmoly_photos/800px-Audeze-lcd2-wiring-scheme.png)
And since we're talking modification: is there any advantage in the double mono over the stereo xlr? I would think it be cable-safer to use the stereo?
is there no technical documentation on http://bryston.com/pages/technical.html? other than the brochure that is?
James could you/Bryston be of assistance with a HD800: "Bryston will also provide modifications to some headphone models to make them compatible with a balanced output configuration, along with an adapter cable assuring backwards compatibility to all traditional (unbalanced) headphone outputs."
Appreciated!

I searched Headroom for further info and correspondency with Headroom about their cable offering gives this by Jorge:

Is it normal for the BHA-1 to be warm, or even get hot after some long playing time, but only on the left side ( behind the volume knob ) ? I was expecting it to be warm on the right side since this is where the transformer is, but on the contrary, it remains cold on the right side. Being a class A, I guess it should run warm, but the transformer does not generate any heat ? Thanks

James, sorry, but this adds to my confusion, please make sure Stu gets this too:
Just received a phonecall from the local Sennheiser dealer. He had forwarded my question to Sennheiser HQ and they state that the HD800 is not a balanced Headphone, it's single ended, just like any normal speaker, and connecting through a balanced cable/amp makes no sense at all, no soundquality effect, let alone improvement :scratch: :scratch: in other words, keep my money in my pocket.
Now what to believe? How come the rave reviews of all those aftermarket cables if the manufacturer of the hd800 says its a single ended headphone.

Hi Marius;
A good resource for your questions is Tyll Hertsens at InnerFidelity.com. He is the original founder of HeadRoom and one of the true experts on headphones out there. He has been known to correct companies like Sennheiser and Beyerdynamic on their own misinformation, wiring mistakes, etc. :O He truly is a wealth of information and just a nice person, very approachable and without attitude.
Just FYI, there is no such thing as a "balanced" headphone, and so of course Sennheiser will repeat that forever. There are only balanced 'configurations' of headphones that can be accomplished with either modifications, or with after-market detachable cables. You sound stressed - don't be. With that particular model HD800, if you poke around, you can find used cables for sale and just experiment and go with whatever you think sounds better, balanced vs. single ended.
-
Thanks Grsimmon,
I'll see to contact Tyll. Saw his videos of reviews and understand your words about him.
Do you have any insight in the cabling scheme of things? Would the one i posted earlier be what I'm looking for with the HD800?

Marius, I'm getting HD800 today, and modifying the OEM cable to 4pin XLR, to add to my Denon AH-D7000 ( which I had modified to 4pinXLR at Bryston). I asked a local technician, who had modified a OEM HD800 cable to two 3pin XLR. He said that when you remove the 1/4" connection from the HD800 cable, you end up with 4 wires, and two ( left, then right ) are used for each 3 pin XLR ( + & -) . The third pin ( ground ) is not used. Now , I do not know if that ends whith a balanced or non balanced formula, but I'll be doing mine with a 4 pin . I don't know if there is any other way to connect the HD800 that will make a difference ( balanced or non balanced ).
-
Hi
Yes - It will get hot on the left side - it is normal.
Thanks James, one more question. Do the balanced inputs on the BHA-1 provide higher gain than the unbalanced ? I know I get louder volume from the front outputs ( XLR Vs 1/4" ), but was not aware of the input gain, as I'm getting louder level of music when I use the XLR inputs. Thanks
-

Hi
Yes - a balanced connection has 6dB more gain than a single ended connection (because it has twice the voltage swing). So if you use a Balanced Source you get the extra 6dB of gain and if you use a balanced XLR Output from the BHA you get a further 6dB of gain for a total of 12dB.
James
PS - another advantage of Balanced is a lower noise floor as well
-
Hi Grsimmon,
Tyll responded:
"You can't use a regular headphone jack to get a balanced connection. You have to replace the plug with two XLRs.
I'd suggest a cable like this: http://www.headphone.com/accessories/cardas-balanced-cable-for-hd800-15ft-neutrik.php
The diagram you showed is not good.
This page might help you understand. http://www.headphone.com/learning-center/art-i-balanced-vs-unbalanced.php
"
Headphone.com show this wiring-scheme: (http://www.headphone.com/images/balancedamp.gif)
on the next page "Balanced" is explained in all its variants, obviously I seek the fully balanced version, which with the BHA1 and a thus modified cable is reached.
Hope to realize this in the next 6 weeks, in the backorder still hold that promise
Thanks all,
Marius
ps James if Stu would confirm this, I'd be really at ease :?

Hi James,
Headroom mentions duo XLR/Jack outputs on its BUDA. Seems nice to be able to listen 'with the two of us" simultaneously. Could that be a special order on the BHA1 too? Or would that require a redesign, which obviously is not in order.

Hi Marius,
Not sure I understand the question but if you are asking if more than one output can be used at the same time the answer is yes. That is the way I typically set them up at shows with 2 to 3 different types of headphones attached to each BHA-1.

Hi Marius, great to see there are others in the same hunt as I am. :D I'm waiting for my BHA and HD800 to be delivered as well, so thanks a bunch for your little research.
I did call Sennheiser as well and they confirmed the setup of the HD800 is fully balanced and suggested to just cut off the unbalanced cinch connector and replace with a balanced set. Which I thought could either be 2 3-pin XLR for left / right or a 4-pin Stereo XLR, like "zeiter" intends to use. That also was my intention, since when I asked James some time ago, while I was still considering a Grado, as he stated that a 4-pin Stereo XLR produces a noticeable better sound and he was using such a config with his Grado, if there was any advantage of a left/right 3-pin XLR over a 4-pin Stereo XLR (as the BHA offers both options). His response was, if I recall correctly, that I should just use a 4-pin Stereo one.
Sennheiser told me, that there are essentially two cables (red = plus & blue = minus) going into each driver. So from that, it might though be just easier to connect each of the two pairs to a mono XLR and then use that configuration over a 4-pin one? If there is no difference?
But if Stu can still confirm, would indeed be great. Can't await my combo to play!!!

Stu's not around, so James asked me to comment. As long as you use either a single 4-pin XLR or a pair of 3-pin XLR's, you are using the BHA1 in balanced mode, and can take advantage of double the output voltage. This is, of course, dependent on the cable having two conductors per side; if the 'common' wire is joined at the phones rather than at the 1/4", you need to replace the entire cable...
I just modified a pair of HD800's yesterday, and the improvement vs unbalanced was significant. In that case, I used the single 4-pin XLR, as the wires are in a single braided jacket, but if someone wanted to get fancy, it would be possible to use a pair of 3-pin XLR's, although it would not improve the results.

James, unless I misunderstood the user manual, it does not recommend using both XLRs up front at the same time as this will create more heat bla bla bla...
-

It really depends on the load of the headphones combined - the more phones the lower the impedance - the more current draw required. The Grados (as shown above at the Montreal Show) are 32 ohms each so multiple versions of them are no issue at all for the BHA-1.
james

Hi James,
I mean this special neutriks:" A pair of Neutrik 'combination' XLR jacks await one balanced headphone OR you can use two standard headphones simultaneously via the full stereo 1/4" plugs housed within each XLR jack!"
Could be a nice option as special order, if at all possible of course.

Hi Mike, excellent and thanks a lot, exactly what I needed to know! So no improvement from 4-pin to a pair of 3-pin. By any chance, would you be able to document how to connect the 4-pin XLR just to make sure we do this right here in good old Germany?
-
Hi Mike,
Thanks a lot for this , make that +1 from the Netherlands.
Just to be sure, you mention you modified the hd800, did you do that with the stock cable? I'll order a spare one in that case and have it modified to your specs. Should have the 4 needed wires. Could you confirm that?

Zeiter, thanks for that hint. Good if one then has the manual....I have not yet seen it downloadable from the Bryston webseite like e.g. the BDA or BDP ones are. Hence it would just be cool to get a little hand from Mike since he just did recable the HD800, since both Marius and I are trying to accomplish exactly that. Cheers.

Sennheiser makes their phones with detachable cable so you do not have to hard wire. This way you can interchange any cable and not have to re-purchase the phones.
Why do you not just borrow cables from your local or not so local dealers and chose the one that sounds best to YOUR ears. This is the flexability of owning Sennheiser.

Hi James,
In deciding my recent BHA1 order/purchase I completely forgot the BDA1 only has 1 set of XLR outs. :duh: Talked about passthroughs on the BHA1, but never realized this before. Since I want the BDA1 to play over both machines obviously, and don't want to plug/unplug cables all the time, please let me ask this:
- Is there a way to connect the BDA1 to the Balanced BHA1 inputs and to the balanced BP26 simultaneously, without compromising the specifications at all? Would a Balanced-Y cable still deliver the voltage swing you always mention, to both machines? Maybe the new balanced outs on the back can be made to passthrough the balanced in?
- If not, what would you advise to be the best choice: BDA1/BP26 balanced and BDA1/BHA1 over the RCA or vice versa. Which machine would use/need the balanced connection most?
- Would there be any difference between the BHA1 connection on the Rca tape out (with all other BP26 sources, including a balanced connected BDA1) or a direct BDA1/BHA1 Rca connection (which is the only one left if I take the BDA1 balanced out to the BP26)?
Thanks,
Marius
-
Hi Marius - yes you could use a Balanced Y cable out of the BDA without compromising performance.
The rear Balanced out on the BHA-1 is in parallel with the front connectors so you could use it that way but both go through the volume control of the BHA-1.
james
-
Hi James thank you .
So no way of 'paralleling' it with the balanced In's instead ?

No, the same would not apply. What you are proposing results in shorting the outputs of the BDA and BCD together - a no-no. You may split the output of a line level device, but you cannot short two outputs together.

Bruce, even if using one unit at a time ? Still a no-no ?
Still a no-no. Matters not that one of the units is powered off since the output transistors will still be connected (shorted) together. You would need a switcher to connect one at a time, or plug and unplug one at a time.

HI James,
Just to be sure, cause I get some feedback about losing several Db with a Y cable? Don't exactly understand , but they seem to indicate if you split a line level output into two, both get less than when not-split.

Can I order a Y-cable at Bryston, to be sure its up to your standard?

Hi Folks,
News from the Front on the Bryston BHA-1 headphone Amp:
MLee
Location: Kentucky
I've had my BHA-1 Headphone amp a couple weeks now. First off I'll say this amp is way more than I need. I figured that it will be a nice amp to have no matter what headphones I try now and in the future.
My two current headphones are the Ultrasone Edition 8 and the Audio Technica W3000anv. Both are easy to drive but show improvement with amplification, and the Bryston made both sound exceptional. I'm not a reviewer nor an advanced audiophile, but the difference in the Bryston versus the Burson 160 or the Objective 2 is somewhere between definite and substantial.
The detail and the "Fullness", for lack of a better term, of the sound is exceptional. Crisp with impact. While the other amps pair well with these two headphones the Bryston is just a step up, no doubt about it. I'm sure others that have harder to drive phones are going to find the Bryston worth every penny. Yeah, it's more than some/most of us spend on an amp in this hobby, but if you have the ability to get it you won't be disappointed.

This BHA-1 is such a bad mutha!
I would honestly just get one if you can and then spend the rest of your head-fi dom playing around with Dacs, cables and phones. I hooked it up to the old DCS stack tonight and god damn it was good. I simply cannot imagine a better amplifier. All of the sonic signature of that system came right through, super black between the notes and dead quiet, superb soundstage and imaging, and detail and nuance to die for without a hint of fatigue. The material was 44.1khz and 96khz up-sampled to DSD via the DCS up-sampler.
I am simply done with headphone amps for now. Now it is on to better software, power conditioning, and little tinfoil hat tweaks. I have never enjoyed my music more. Even my dad (dCS owner) was impressed.
It isn't just an amp, this must be state of the art right now for solid state.
Now that it is broke in, I just love how right when those loud congested passages come in where you think you are going to get an earful of shreaking pain, the BHA-1 (and PS1000s) sort it all out into a million tiny little waves tickling your ear drums.
Yes, I love this system

Yes, those would do the job fine. Hosa is known for budget cables, with the other cable being the better of the two choices you show.

HI Brucek,
Thanks, I've asked Bryston whether they'd make me a cable too, hope they will, thus keeping it all in the family, and, more importantly, up to Bryston standards.
Since we're talking special order cables, would you think a longer Balanced Y cable, connected directly to the BHA1 and BP26 instead of through these short ones, with an extra connection, is preferable?

I would think a single cable with the two tails a suitable length to satisfy the furthest distance you could imagine your equipment being located would be best. If the equipment is placed closer, no problem as balanced connections are very forgiving of length.

My knowledge of the headphone world is what I read here, limited internet research and the use of a Bose noise-reduction headphone on airline flights. I am thinking about buying a BHA-1 and high end headphones and the issue of cables somewhat baffles me. It appears that most headphones are supplied with a phono connector but, for example, the HiFiMan HE-6 comes with a 4 pin XLR cable (gender unspecified). On this forum several months ago there was discussion about the BHA-1 being produced with the option of male or female XLR connectors and I see that AudioAdvisor is in-fact offering a BHA-1M and a BHA-1F. The female version seems to make the most sense to me; however, can anyone shed some light on this issue? When buying stock headphones and/or XLR headphone cables, what will I find on the amp end? Is one more prevalent? I am trying to understand which is most useful in order to avoid gender changing adapters. Anyone?

On this forum several months ago there was discussion about the BHA-1 being produced with the option of male or female XLR connectors and I see that AudioAdvisor is in-fact offering a BHA-1M and a BHA-1F. The female version seems to make the most sense to me; however, can anyone shed some light on this issue? When buying stock headphones and/or XLR headphone cables, what will I find on the amp end? Is one more prevalent? I am trying to understand which is most useful in order to avoid gender changing adapters. Anyone?
Tony
You want FEMALE on the BHA-1 as most headphones come with a MALE connector. I think that is where the confusion comes from. In the PRO market signal always travels from a Male to a Female connector and that is considered the standard in most consumer products as well.
I think the Headphone connector being typically a MALE 1/4 inch type connector morphed into a Male XLR cable because most folks were familiar with plugging the 1/4 inch Male into a female on most gear.

Thanks, James. That certainly makes sense to me but I had not been able to confirm it. Even the picture that Audio Advisor is showing for the female version as well as the male version shows the male connector.

James,
The top picture looks like one of those artist's rendering back in the development process -- no balance control and has a mini-phono plug.

check, +1, on the technical page of Bryston.com the Bha1 is missing....
Would there be a downloadable manual (not the Brochure) ?
Marius
Marius, just fyi - am picking up my HD800 the coming weekend, with a 4-pin Stereo XLR male connector. You by now probably saw the wiring specs in the BHA-1 owners manual that James would have emailed you. I had Sennheiser HQ Germany confirm the wiring specs of the HD800 as follows.
right driver (+) = red, (-) = white
left driver (+) = green, (-) = white
Hope that helps further. Cheers!
-
sure does, thanks a lot.
hope to hear from you and your HD800 soon!

Well, just got the message: 460 for the pair of y cables, which is to steep for me. Rediculous really. 3 sets of splitters would cost as much as the whole BHa1...
Thanks, but no thanks,
Marius
HI Brucek,
Thanks, I've asked Bryston whether they'd make me a cable too, hope they will, thus keeping it all in the family, and, more importantly, up to Bryston standards.
Since we're talking special order cables, would you think a longer Balanced Y cable, connected directly to the BHA1 and BP26 instead of through these short ones, with an extra connection, is preferable?

Hi Marius,
You sound like me - adverse to spending a disproportionate amount of money (relative to equipment) on cables.
When the BHA-1 just arrived, I conveniently connected the BHA-1 directly to my cheap NAD C542 CD Player. The headphones I use most frequently are the Hifiman HE-6. I was very happy with the sound.
I have since moved the BHA-1 to my main rig. In this main rig, my BCD-1 (SPDIF) and BDP-1 (AES/EBU) are connected to my BDA-1, which in turn is connected to my BP-26 Preamp. I then connected my BHA-1 to the Tape Out of the BP-26. I use a very inexpensive RCA cable (Belden cable; Canare RCA plugs) which I got a shop to custom-make for me locally for about US$50.
I am very happy with the sound I get. Despite using an inexpensive RCA cable, I am still able to hear "new" things on familiar recordings which previously eluded me. If you have a pair of RCA cables lying around unused - many of us do - perhaps you want to just try the Tape Out from the BP-26.

Hi Myview,
Thanks, good to hear! I will follow your setup, James advises this also.
Would love the Balanced connection simultaneously though, but can not justify these.
Will have them made locally.
Cheers!

Hi everyone,
Because I was a bit overwhelmed by the cost of the Y-splitter cables, I asked again and these were advised to me: Microphone Splitter http://whirlwindusa.com/support/tech-articles/microphone-splitters/
Can be had for as low as 15 $, up to about 200, don;t have the price of the Whirlwind, which probably is a bit more expensive, Whirlwind is priced competitively http://www.jr.com/product/productListing.jsp?Ntt=whirlwind+splitter 90 for the 2way, but note the 20hz - 20khz freq response....
Anyway, my question is more about the technique and quality of it, compared to a Y cable. Alleged advantage supposed to be: no BDA1 signal loss because of split, and galvanically separated, no physical connection between the two Amps (BHA1 and BP26).
Worth the try?
Thanks for any comments or experience

I think microphone splitters are MONO and not STEREO, which means one plug 3pin XLR only.

Don't take this the wrong way, but you're making this more difficult than it needs to be.
Simply purchase a decent splitter (http://store.haveinc.com/p-47684-haveflex-starquad-y-xlrf-2xlrm-6.aspx), and then add a couple XLR cables (http://www.bhphotovideo.com/c/product/68097-REG/Audio_Technica_AT8314_10_3_pin_XLR_Male_to.html) and the jobs done. Under $70.

Hi Steve ,
I'm no good doing that.... The aspect of connecting the two machines with the splitter is what started me doubting. Will see if it's indeed no good and deteriorates the quality if sound, requiring the galvanic separation, or whether theory and practice are not the same after all.
Thanks,

Hi James,
As I mentioned (of topic) on another tread, I was going to audition your headphone amp. Did so today. Brought my own Grado GS1000 headphones and my Lehmann headphone amp for comparison. Also listened to the Sennheiser HD800.
I fully expected a big difference in character between the Grado and the Senn. What I was not prepared for was the actual difference between the Lehmann and BHA-1. I used to think that I had one of the best headphone amps out there, Sennheiser even used them at the demo during the launch of the HD800. However, the sound from the BHA-1 was much more open and so much closer to “being there”. The Lehmann had an abundance of high’s and low’s, but sounded much more clinical. The BHA oozed music and was much more “3-dimensional” if you will. What a machine! :thumb:
IMO the difference between the phones was more a matter of taste than an actual difference in quality, both having an astounding level of detail. For classical music I definitely preferred the airiness of the Sennheiser, but the directness of the Grado was great for Jazz.
Needless to say I ordered the BHA-1 (and a HD800 for good measure). Had already decided on the BDP/BDA combo. For headphone music this is about as good as it gets! Now all I need is an aftermarket XLR cable for the Senn!
Cheers,
Bob

It will be good and there will be no loss in sound quality. My suggestion was the path of least fuss, providing a single cable to accomplish the task at hand. It had little to do with sound quality and was somewhat predicated on an assumption that people that purchase Bryston equipment will pay big for convenience. hehehe
XLR's offer a very positive connection, so the extra set of connections as a result of the splitter will not deteriorate your signal.

Hi Bob, am just about to get my BHA and HD800. Will have the cinch of the standard cable cut off and connect a 4-pin Stereo XLR, see pin specs in an earlier thread here. The cut-off / new connector way was actually a Senn HQ Germany reco. Senn will shortly also offer a balanced cable themselves, but they don't know yet when. So unless you want to continue to use the original unbalanced setup as well, you can even save an aftermarket cable.

Hi Marius, I will connect my BHA via RCA using the tape-out (of my GamuT DI150). I have recos from both Bryston and others, who had a bit of a look at the BHA setup and say, that the RCA connection will actually produce a very very good result. Initially I tought I must go balanced in this connection as well, but don't think so any longer. So I will get myself a decent RCA cable and am sure this will be it. But you can for sure maybe try both and see what fits your taste best. I just think all the splitter considerations may in the end turn out to be too much of a worry.
-
Thanks Joker,
Will see if I can get it with the XLR cable from Sennheiser directly.
Just as Marius I am hesitatant to cut the factory cable to pieces.
Bob

I did cut mine last weekend, just replaced the plug with a 4pin xlr. I'm extremely happy with the results. I did exactly the same few weeks ago with my Denon AH-D7000 and very satisfied also. According to the tech who did the mod for me, the HD800 have a very high quality cable from factory, copper with silver plating, so it's a waste to replace it . But, like with interconnects, to each his own. I like both headphones with the BHA-1 ( they're completely different ), and the amp drives both very well. Can't comment on the HD800 improvment, as I purchased them after the amp, and never used them with anything else. But the AH-D7000, I've had for a couple of years, and used with different amps, they're much easier to drive compared to the HD800, having 25 ohms compared to 300 ohms, and more sensitive, but regardless, they never sounded as good as with the BHA-1. My sourcs are the BCD-1 balanced , and the BDA-1 unbalanced for now. I would say with the HD800 and BDA-1 unbalanced, you have to increase the volume quite a bit, as I loose already 6 db to balanced connection as James explained it. Once I'm balanced, everything is perfectly OK, even having 300 ohms. Denons, not an issue with any input. End result, I'm in love with that amp.

HI Joker, Bob,
I ordered an extra factory Sennheiser cable, to replace the Jack of one of those with the 4-pin XLR according to Bryston's and Sennheisers scheme. Will have both connections that way, and I am very anxious to hear the various advantages/differences.
Great to read you all are so very happy with the BHA1 (and hd800). Hope to join you soon!

You're probably right. I guess we will have to decide which of the connections is served best with the balanced BDA1 route: BHA1 or BP26. Hope the backorder won't take too long to come to Holland.

Sanjay, no need to recable. I just purchased the 4pin XLR Neutrik plug at $6, you can change the plug yourself or have somebody do it for you. And if you don't want to, just use the standard 1/4" up front, and unbalanced RCA inputs in the back. Now for the price of the BHA-1, IMO I still find it reasonably priced compared to other amps, and given its performance, and warranty offer.
-
Today just turned into a great day. My local dealer called and said the BHA1 has arrived at his store. So, I am heading out shortly to collect this unit and will report back in a few weeks with a review of what I think of this long awaited acquisition of the Bryston family . :thumb:

Hi Christopher
I have used 8 pairs at shows for demo purposes but it all depends on the combined impedance of all the phones attached. The lower the impedance the more current is needed.
What is the impedance and efficency of the HD650's?
james
-
I would happen to know that since I own a pair... 300 ohms and 102 dB/... hm, the SPL is specced at dB/V. Unusual?
-
HI,
300 ohms is fairly high and 102dB is good sensitivity so my quess is you would be OK but I will ask engineering when I get back after the Toronto Audio show.
When I used the 8 pairs they were all Grados with an impedance of 30 ohms.

Hi James,
JohnR is correct....300 ohms and 102 db.
I would appreciate your asking engineering to find out if this set up would be ok. I am thinking of expanding the system to possibly 24 HD650's. Any info would be great. If the BHA-1 could handle 18 HD650 headphones with no problem, I would be seriously interested in purchasing one :-)

Hi Chris,
Just out of curiousity (I am really trying to learn here), under what circumstances would you need to run this many pairs of identical headphones together?

Hello,
I am doing a kind of workshop but instead of talking, I am performing improvised music and sound. It is not a concert, I am using sound vibrations which facilitate increased awareness in the listener . It is a touring system so it has to remain somewhat portable. Speakers take too long to set up and calibrate and are difficult to move around (I am in Japan). Speakers also require that the event space have acoustic properties and is relatively soundproof. The speaker scenario is too restrictive for this project. Headphones basically eliminate these problems. Also, I am using high definition 3D audio and generally, headphones work best for that.
Hope that answers your question ;-)

Found out today from PMC that after what seems the longest wait ever for a new product that my BHA-1 is actually in the UK and I should be getting it on Friday, I really never thought this day would come :)
I opened a Sennheiser account last week so I'll be able to put the Grado PS1000's up against the Sennheiser HD800 as well as the BHA-1 v the new Sennheiser headphone amp, the HDVD800 which I should have in a couple of weeks, exciting times indeed.

Picked up my BHA today. Listening to a pair of HiFiman HE-500. Wow, I have the gain up and listening in the balanced mode and these cans are loud at about 9 o'clock. I'm sure the BHA can drive some of the very efficient speakers out there. I'm interested to see what this sounds like as a preamp. Will report when everything breaks in.

HI James,
ordered my BHA1 a couple of weeks ago, any idea how long I will have to wait?
Needless to say you need to compensate for the long wait with your personal signature on this one :thumb:

Hi,
Engineering tells me maximum 10 pairs at a time based on 300 ohms.
james
Hi James!
Thanks for the information. It seems that my solution would be to have two BHA-1 Headphone amps. Currently, I am running 10 headphones on my system plus two more from my Metric Halo ULN-8 IO headphone out. This means I could use one BHA-1 with my current setup but If I expand, I would have to get a second BHA-1. Lots to think about ;-)
Thanks again for the info!

Who said miracles can't happen, after what seems like months of waiting my BHA-1 has just arrived, and as a bonus I've got a pair of Sennheiser HD700's arriving tomorrow :)
Right, must dash, I've got more important things to do than being on here :wink:

Today I made the journey north of my London home to visit Hi-Fi Lounge.
It took 45 minutes door to door - less time than travelling into central London. With the added bonus of having the car (in the car park) ready to take home any purchases (or stolen items).
The building (both inside & out) & surrounding area are beautiful, and there are no issues with noise - ironically.
Paul and his wife, Wendy, were there today. And they make a fine team. Paul is a very eager and enthusiastic man, friendly and brimming with energy.
And combined with the laid back vibe of the whole establishment, it all comes together to form a relaxed and very pleasant atmosphere. Almost akin to being at a friend's home for a night of hi-fi nirvana.
Inside, there are 3 rooms on 2 levels. The main room includes an AV set up & those huge PMC MB2s. Downstairs in the 2nd room it is more restrained, with various equipment, and the 3rd is a dedicated headphone lounge. And it is the contents of this room with which I was very impressed........
The Bryston BHA-1 Headphone Amp had only just arrived. With a full selection of lovely Grado cans on display I began at the very top - the PS1000, costing an eye watering £2000!
Sitting snugly on my little head I began with Alanis Morissette singing in my ears. And then moved on to Queens of the Stone Age, and some classic Faith No More.
I wasn't expecting the excellent detail retrieval or the bright presentation. They certainly didn't have the familiar Grado sound.
Next up was the GS1000, at £1000. These sounded far more familiar, nowhere near as detailed, but the warmth gave the sound a real charm. But they sounded a little muddy after their bigger brother.
Finally I tried the PS500, a snip at £700. And straight away I knew I'd found 'the one'. The warmth of the GS1000 was there, along with a great deal of detail and punch. The bass was full, energetic & nicely defined, and a real sweetness to the mids and highs. And a better balance to the overall sound, too - lovely.
The Bryston BHA-1 wasn't too shabby, either! Well done, James.

Hi James,
The shop takes me back to my youth, when I first discovered hi-fi and a love of music. There is a personal touch and I really can see the making of many a relationship in that shop, myself included. Something which has been sadly missing for many a year.
So yes, 'a class establishment'. It's got me thinking about the BHA-1 now!

Hey there,
I was unsure of who to send this message to. I just purchased a used Bryston BHA-1 from a friend, who purchased it from moon-audio.com on 8/21/2012.
I must first tell you that my Grado PS1000s have never sounded better. I have been grinning for 3 days straight, haha!
I couldn't be more happy with it. The PS1000s are low ohm, so I barely have to turn the volume up, but the sound is just so mesmerizing and textured. I'm blown away.
Thanks,

Hi Kyri,
Thanks for all the kind words mate, it was really good to see you the other day, although you did hog the BHA-1, I've only been waiting 6 months for it and as soon as I'd set it up you were in the hot seat, perfect timing on your part :wink:
I actually need someone to run all my headphones in so if you've got a spare week or so I have a job for you :) I have to say that I was amazed at the sound leakage from the Grado's, it's the fisrt time I've experienced that as they are ususally on my head, I was downstairs with Kyri upstairs and I could sing along to what he was listening to, they really are ear speakers.
I still can't believe that after all this waiting I haven't spent any time with the BHA-1 yet, I've got an install tomorrow morning then I've put a few quality hours to one side in the afternoon for me and the BHA-1, so hopefully I'll be able to post my thoughts tomorrow, I really can't wait :)
-
Quick question James, can the BHA-1's volume be controlled with either the BR2 or BR3?
-
Tomorrow I'm going to fit the BHA-1 into my Bryston system comprising of the BCD-1, BDA-1, BDP-1, 7B's and SP3, what is considered the best way of hooking this all up? ideally keeping the BHA-1 balanced, I really only need to use the BDP-1 as the source, keeping that balanced as well.
Is it a case of using XLR splitter cables? will this degrade the quality in any way?
Thanks,

Hi Vipers - no sorry the volume control is not remote-able.

Christmas has arrived early this year, :hyper:
A couple of day ago Santa came round to my house and delivered a neat BDP/BDA/BHA package, supplemented with a Senn HD800 and some up market interconnects. Have added them to my setup and have been glued to the cans ever since.
Have read a lot on burning in the equipment, but right out of the box this gear sounds just wonderful. Have been able to compare CD’s in my BCD (quite lovely) to the ripped versions from the BDP/BDA combo (so much better). The most striking difference is the sense of space and ambiance oozing from the digital player. A lot of the credit must go to the BHA however. Combined with the Senn (unbalanced so far) the sound is mesmerizing and on more than one occasion has made my hair stand up. After all we are all in it for the music and the way Ella’s voice and feelings are conveyed by this piece of Bryston magic (Intimate Ella; just about the best CD I own) is truly unbelievable.
So far I have mostly listened to CD rips, but I am now starting my journey into the fields of High Res music. Just wish the main stream music publishers would accompany their releases by the FLAC masters.
Cheers,
Bob

Hi Folks,
Which RCA brand cables do you suggest between BDA-1 and BHA-1?
Thanks for all constructive suggestions in advance!
:D
-
Hi Larevoj,
Would not want to suggest anything, as I did not compare my cables to other types or brands, but I use a Siltech (Classic) AES/EBU cable, with very good results.
Must be a substantial number of posts on this subject, either on this forum, or on the BDP sub-forum.
Cheers,
Bob

After months of waiting my BHA-1 arrived towards the end of last week and yesterday I sat down for a few hours to put it through it's paces, all I can say is BHA-1 = OMFG :icon_surprised:
Actually James I think you should have called it the OMFG-1 :) What a piece of kit, it was certainly worth the wait.
First of all I tried the BHA-1 as a pre-amp out of curiosity, hooked upto a 4B SST2 with the BDP-1 and BDA-1, all balanced, what an amazing system, it sounded fantastic, I think this feature really shouldn't be overlooked as this system is a cracking set-up and as long as you don't need more than one source hooked up offers fantastic performance
Then for the real test, the BHA-1 connected to the BDP-1 and BDA-1 using balanced cables again, with my Grado PS1000's, un-balanced unfortunately, I played with the gain settings but with the Grado's preferred the high setting. I have to say I really wasn't expecting the quality jump compared to the SP3 headphone out, which is no slouch it has to be said, but the difference really isn't subtle, through the BHA-1 the PS1000's just came alive, it was like I'd bought a new pair of headphones, it does make me wonder how many people have never heard their headphones real performance, I tried various recordings all with the same effect, but when listening to the Eagles 'Hotel California' from the Hell Freezes Over CD, as an example, I was quite simply amazed at the clarity, separation, dynamics and detail that the BHA-1 was retrieving, it was simply astonishing.
I tried the BHA-1 with a Naim streamer connected via RCA's, it still sounded fantastic but was not in the same league as when connected to the BDP-1/BDA-1 combo, if you are into your headphones then I really believe this to be headphone nirvana, it is for me anyway :)
Over here in the UK, the BHA-1 costs £1425 which I feel makes it the bargain of the century, especially at the moment when Bryston prices in the UK have been questioned a few times, as not only do you get a truly reference headphone amplifier but also a top end Pre-amp, you can't ask for more than that.
Quick question James, I tried to implement into my current setup, this worked quite well but I'm not sure if you'd recommend it ? All Balanced, I run the BDA-1 into the BHA-1 input then run the BHA-1 output into the SP3 input, then when selecting balanced 1 on the SP3 I would get sound from my speakers but nothing out the BHA-1 but as soon as the SP3 was turned off then the BHA-1 came alive, it seemed to work OK but I'm guessing that there would be some degradation to overall sound quality to the SP3 due to not connecting the source directly to it?
All in all though I'm amazed at the performance of the BHA-1, basically I've never heard my headphones driven properly, it is amazing how with the BHA-1 they came alive, well done to everyone involved at Bryston, the BHA-1 really is a true reference product :thumb:

Hi Bob,
Beautiful setup you have there, you are right though, the BHA-1 is very special indeed :)
I've opened a Sennheiser account, but am still waiting for my HD700's and HD800's to arrive, I've heard the 800's before but preferred the Grado's, but hearing how much my Grado's improved with the BHA-1 I think my opinions on the HD800's could be about to change.
I've ordered that Intimate Ella cd by the way, thanks for the heads up :)
-
Thanks,
If you like Elly, which you obviously do, IMO it is the best CD around, small backing combo, no big band orchestra, Ella at her peak, more than decent recording.
Would love to hear your opinion!
Have the Grado GS1000 myself, which is great for jazz and such. For classical, especially orchestral, music it is no match for the HD800's.
Cheers,
Bob

Another worthwhile great review James, I especially agree with the below, after listening to this track myself repeatedly yesterday it is if I wrote it myself -
'I then went back to a FLAC file Hotel California. Listening to slow rock and in this live performance by the Eagles is even much more soothing. The live ambience was delivered by the Bryston through my cans that made me feel that I was at the concert and audience are supplied with a personalised headphones. The drums and guitars on this track was so refine and detailed out that you can here every single strumming and plucking the Eagles. This was one track that I repeated thrice just because it sounded too good to be true that I had to confirm and reconfirm the statement I made above. And each time, the Bryston just keep presenting a lively experience.'

Look what has just turned up, not quite the 800's but a good start, some competition to the Grado's maybe, time to get busy :)

Vipers,
If you have a chance, try to get a pair of Hifiman HE-6 (the current top of the line) and/or the HE-500 and try them on the BHA-1. They sound superb and offer a different take on the music as compared to the Grados and Sennheisers.

Hi Myview, I agree 100%, I've been in talks with the UK distributors for HiFiman, Stax and Audeze, and to be honest they have been the hardest accounts to open.
I think they don't want too many dealers to be honest and as I'm the new kid on the block I think they are waiting to see what happens, I find it a little frustrating though as both the HE-6's and the LCD-2's and 3's will sound amazing on the BHA-1 and I bet there aren't many demo facilities that have it on demo at the moment, I guess it's one step at a time though :roll:
I guess I've got enough toys to keep me busy for now :)

Have tried the BHA-1 to 4BSST2 combination at a dealer (now own the BHA with the balanced outs as shown).

Here's a picture of a pair of HD800s being driven by a BHA-1 at last weekend's Sydney AV and Hifi Show. One HD800 was connected with the stock (single-ended) cable, the other by a balanced Cardas cable. The difference between them was quite remarkable - frankly I wouldn't have believed it if someone had told me. The rep there (Syntec, who is I believe the Australian distributor for both Bryston and Sennheiser) said that the difference was largely due to the balanced connection and not the wire.

as good as the balanced one.

Hi Guys,
Just got the LCD-2's in to play with on the BHA-1 at HiFi Lounge, I've had a quick listen and they sound pretty good, I'll give them a good workout later, seem pretty hard to drive to get any real volume though, looking forward to hooking up the BDA-1 and BDP-1 full time in the headphone room as the BHA-1 really does seem to respond to a balanced feed in, just waiting for the LCD-3's. HD800's and HE-6's to come in then I feel we have everything we need to offer the best headphones with the worlds best headphone amp :)

Hi James,
Not much you can do? I don't know, but as far as I am concerned, I ordered the bHA1, a rather substantial order, and it seems a bit odd that anyone, even the national importer, says the customers interests are less important than theirs...? Bryston selects their local distributors, so Bryston defines its own business-policy?
I mean, where does this end? Will Mafico give green light to my order when they see fit? Might be next year or so. The price increase would justify a single shipment anyhow....
I'd hope Bryston would have their own governance in this, and take customers as the ultimate reference. I buy Bryston, because you say that is the Bryston Philosophy.

If not packed yet: I need a longer connection power cable for my Bp1.5 to the MPS-2, could you drop that in the box? 1.2meter should be sufficient.

Thanks, James. I realized that I said RCA when in fact I meant single-ended. Of course, I'm referring to the single-ended and XLR headphone outputs, not the the new XLR preamp output. Still 3 ohms? Just making sure that we are talking about the same thing. :D

I will confirm with engineering for you but I do know it is very low.

James,
Considering the heat generated by the BHA-1, do you see a problem stacking another component on top of it.
Thanks

I would say as long as the unit on top is not generating a lot of heat you are OK. The whole chassis acts as a heat sinc so it is best to allow some airflow around it.

It would be great if this could be published with the other specs on the Bryston website for the BHA-1. I had previously looked there for the output impedence information and couldn't find any.

HD-800 arrived today, enjoying to the limit right now. Hope the BHA1 will come next week, and multiply this experience...

Hi Marius,
Seem to remember seeing one of your playlists on this forum, that indicated you are fond of music from the renissance period.
This seems ideally suited for the BHA-1 / HD800 combo. Have played a few Bach Cantatas that completely blew me away.
Hope the BHA will arrive soon.
Cheers,

Hi Bob,
Thanks, and yes, one of the first i tried was the latest Tallis Scholars hires download. Sounds wonderful indeed, though a completely different experience compared to playing over the speakers it is. Soundstage is big, but not in front. More in the head....(seems kinda logical ) Always feel more to 'myself' with headphones. Guess that also one of the main reasons to like it, a bit of a recluse....
Playing on my bp26, first thing to notice is that it lacks some juice for the hd800 to really come to life, the BHA1 is needed indeed. Comparable to playing the ESL's before the Bp26/28's, and them coming to after after that decision.
What i hadn't noticed before, is that the balance knob of the bp26 has definite stops before reaching the outer limits of turning. you can hear the channels kick in, instead of evenly coming up/going down to 0. I hadn't noticed that before on my ESL's. Apparently the HD800 are even better monitors?
3d thing i tried, because I never heard any significant difference, was playing the bcd1 over its own XLR out or connected to the BDA1 XLR out: again, there's no difference at all to my ears. Both sound as marvelous as they do.
So, as you can imagine, i'm looking forward to the BHA-1's arrival next week!
Thanks, and if you have some listening tips for the recluse, please let us know?
Marius
ps which Bach recording did you listen to? I am very fond of the Gardiner recordings on Soli Deo Gloria. Which reminds me of the next testcase for the hd800: Simon Prestons recordings of Bach organ music. Amazingly good recordings (organs are notoriously difficult to record in their Church ambiance) and beautiful performances. that is to top the sheer joy of Bach's music, both subdued and virtuoso.

Hi Marius,
Am a fan of Harmonia Mundi, for their talanted performers and the great recordings. At this time I mostly listen to CD rips through the BDP. Would be great to have access to the high-res recordings at HDtracks,but have not tried to get at them yet. They have a number of Harmonia Mundi recordings on there and I am certain they sound even better. As you know regular access is prohibited at this time.
The recording I heard was:

O yes, I agree, HM have a lot of great recordings in their catalogue, as a matter of fact, yesterday the latest recording in Rene Jacobs's Mozart Opera cycle was delivered: La Finta Giardiniera, http://www.harmoniamundi.com/#/albums?view=playlists&id=1851
I know the Collegium Vocale and Herreweghe well, Ive played in Gent for 17 years.
What do you mean with HD tracks being prohibited? I dl'ed a new recording 2 days ago....?

Hi Marius,
HDtracks does not allow payment with my (european) creditcard. Am currently in the US and tried again from a US IP-address, no such luck.
I know paypal payment might be better, but have not tried that yet, to busy listening to my new gear and ripping a few thousand CD's.
You said you played in Gent, wow, what instrument do you play?
Bob

this might wonder away from the topic, but to be quick: yes i always pay with my Paypal, works fine.
I play(ed) timpani and percussion at www.vlaamseopera.be up to 2006. And I feel for you in the ripping process.... been there, done that, still going strong.....

Hi James,
Just letting you know that I was able to pick the unit up from Audio-One last Friday .... thanks for the quick shipping!!!
After listening to them for only a few minutes I put my Trafomatic up for sale. It was really no contest. They sound fantastic with all the headphones I have on hand and I cannot wait to hear them balanced with my Fostex th900 when it gets back from modding.
Bryston really has done a great job with this product; nice to see a Canadian company showing others how it should be done.
Congratulations!

It did this evening! Had to leave immediately unfortunately :cry:
Was able to set it up, connected to the 'to tape' out of the bp26, and will test tonight I hope. James, thanks a lot for this great service.
Also, a separate package was delivered, with a tailor made cable I asked for, but was too late to throw into the box. Bryston, thank you :thumb: what a great company you have James. You neednt, but you did anyhow, amazing, how's that for a customer faced business model.

Hi Marius,
How are you getting on with your HD800's and BHA-1?
I got my HD800's through yesterday and I have to say when I was demoing headphones last year I demoed several pairs including the HD800’s at a reasonably local hifi shop, at the time I really wasn’t impressed with the HD800’s and ended up buying some Grado's, but after spending some time with them earlier I have now realised that it wasn’t the HD800’s that were at fault but in fact the shop I went to had the headphones but didn’t have a headphone amp to do them justice, which is criminal really, it was like I was listening to a different Headphone when using the Bryston BHA-1 to drive them, I can now see what all the fuss is about with the HD800's, extremely comfortable as well.
I’ve got them running round the clock on our Bryston BHA-1 at the moment to run them in to get them sounding their best, can't wait to get a few hours on them to hear what they really are capable of.

Hi Paul,
Gee, wish I had had more time this week, in fact only had the opportunity to hook them up really. Haven't got my balanced cable yet, and playing through the tape in rca's now. Will try balanced soon. the BHA1 certainly has the juice I found lacking in my initial listening on the BP26. I agree on the comfort you mention, but haven't tested a complete Ring yet.....
And, to be honest, I still have to get adjusted to headphone listening, I feel it is a completely different experience all together. The space and soundstage is excellent, as is the frequency response from deep down to up there in the highs. Tallis Scholars soprano;s don't distort, even in high volumes. Something even my ESL had trouble with.
I do feel the upper frequencies tend to take the stage, and believe some xtra playing-time is needed for complete balance to be able to judge. And that is something I never experienced before.
Which gain-setting do you use? James, if you read this, is it better for noise-levels or other aspects, to use the low gain and crank it up a bit, or just use the hi-gain. Hd800 feels comfortable with both I guess, and i like the extra 'room' the low-gain gives me adjusting the volume. And how would this change with the balanced-outs? Will I have to turn the BHA-1 down again for the same volume- level?
Hope to be back this week with more listening-hours.
Cheers,
Marius

Hi Marius,
You will get a different experience with headphones because the sound is not altered by room acoustics the way loudspeakers are, you will get a more honest representation of the music you are listening to. Also remember Sennheiser's HD800 driver's are angled and are the largest of any other headphone available and that will give you a larger soundstage and more fuller presentation. The only knock on the HD800 is the tipped upper frequencies which do not seem to bother me yet and i've owned them for 2 yrs already.
Glad you are enjoying them with Bryston's BHA1 - a very neutral and transparent combination indeed and with time gets better.

Hi Marius
It really depends on the efficiency of the headphones but other than the HE6 phones I typically use the lower gain setting.
I now have 6 pairs of different phones - and that's from a guy that never listened to headphones prior to the BHA :duh:
James
-
ok here goes: taking James's words into account about gain setting , i tried both balanced and unbalanced connection between the BDA1 and the BP26 respectively. (Can't have both balanced at the same time because of lack of double outs or passthrough....)
the difference is remarkable: the air, the ambiance, the whole soundstage, when connected Balanced, the BHA1 and the HD800 really sing, I would describe it best as 'life'. Being there. Have tried meticulously to adjust the volume level to see if it was not just that, but must come to the conclusion Balanced is the way to go. (and I still haven't even got my balanced headphone cable). O boy, what a luscious couple this makes. Mellow, sparkling, full-bodied and honest. You can almost see, feel and 'touch' the musicians. It's all there! :thumb:
Which of course poses the feared and dreaded dilemma: I (we) need the balanced connection in normal (speaker) setup too, for all the same reasons .... James, though the tape-in connection on the bp26 is a viable option for the BHA1, Balanced really is the way to go. ( To save the Balanced out for the Bha1, i tried the unbalanced out on the BDA1 too, but that still leads to the same conclusion...)
Couldn't you make some kind of small switchbox that concurs with Bryston demands and specifics, and allows for switching (not splitting) a balanced signal into different (BHA1 and BP26 in my case for now, but ymmv) amps?
Then your customers could enjoy both worlds of music-playing walhalla.
Cheers, and fingers crossed,
Marius
Will experiment further, especially considering that the BHA1/hd800 might be a much more revealaing combo than the BP26/ESl. Thus emphasizing the difference between Balanced/Unbalanced, which would be a reason to use the Balanced connection for the BHA1 for now and leave the Bp26 with the unbalanced? :scratch:
-
Hi Marius,
Good to hear you got to do some listening at last. Quite a dilemma, for which route to use the balanced approach. For me the choice is easy as I have the B100 which only has RCA in's. To quote a great Dutch philosopher: Each disadvantage has it's advantage. Would love to own the 28's one day.
Due to the proximity of my neighbors, I use the headphone for serious listening anyway. Does not get any closer to a live experience than that. As you are a musician, I am sure you are a better judge of that.
Have also ordered a balanced cable for the HD800 to see if this lifts the experience even further.
Enjoy!
Bob

HI James,
just because it's so different from the other Bryston gear: is it correct that the XLR-ins on the back don;t have the release-levers? I noticed because my cables came out by them selves moving the BHA1...If so, why did you decide on that? And, the little green power-led sticks out, where all the other leds are recessed within the aluminium frontpanels, is that as supposed to?
I know, the devil is in the details.
Cheers,

Hi Marius
We felt it was safer to use the non locking XLRs with the headphone amp as we did not want people forgetting they had headphones on and walk away and pull the BHA off the shelf or worst break the connection on the headphone cable.
Not sure on the power indicator position - I will as the engineer.
James

Thanks Marius for your impressions.
I have fond memories of 800 at shows and rather unimpressive impression of T1 and I am wondering if T1s were lacking juice, in which case this amp in balanced mode could be the ticket.
Anyone tried T1s on BHA1 and how they compared with the 800s.
I am undecided between reference in ear or over the ear system :scratch:

Hi James,
Sure, the front xlrs seems most safe this way, but I meant the back xlr in's.

Hi James, picked up my BHA and HD800 yesterday and just got both hooked up. So will give both a serious workout over the coming days and will report back soon.
Given the BHA produces more heat, would I be able to leave it switched on all the time as I do with my BDA and BDP? I have enough space left / right and on top and it sits on its own shelf. Or do you rather reco to switch it off e.g. overnight?
Thanks a lot!

Hi Joker
It does run Class A with high bias so it will get warm - a lot depends on the venting around it - I would tend to turn it off but it does have thermal disconnect if it should ever get too hot..
Looking forward to your report.

Nope, not yet. My options are 1) standalone with the BDA/BDP combo and hd800, or 2) incorporated into my main system, with bp26 and 28's. No need for the BHA as a full pre-amp yet. Maybe Ill give it a try just for experiments sake, but am struggling with option 2 for now...

Let us know how you get on with the spliced XLR cable, think that was your plan.
Bryston makes good XLR cables I hear, perhaps they can come up with a twin XLR cable.
You can't be the only one with this issue.
Would be interested in your findings one you get to compare the BHA as a preamp to the BP26.
(am considering a 4BSST2 upgrade in the future)

Splitting a signal in a high impedance connection doesn't effect the voltage swing.

Hi Brucek,
really? I believe James told me the total amount of line level was divided over the two when split :scratch:
second to that, apparently it is rather difficult to maintain the balanced construction with a splitter-cable. Difficult enough to cost about 460 dollar....
All the more reason I started looking for a switcher, instead of a splitter.
Cheers!

Splitting a signal from a low impedance source to two high impedance sources divides the impedance that the source sees - not the voltage. It's not a power connection - negligible current is being drawn, so the voltage is maintained.
The only difficulty in producing a balanced splitter is soldering two wires on a pin rather than one. I have no doubt they overcharge for it though. I can't imagine a splitter box would be less difficult or expensive to create.

Hi Marius,
Glad to hear that you are actually getting some quality time with your BHA-1 and HD800's, I've still got my HD800's running round the clock to run them in but hopefully tonight I'll get a chance to have a real listen.
Like you I found balanced is the only way to go with the BHA-1, it seems to make a pretty significant step up in overall quality, as does most Bryston kit to be honest, I'm lucky as I'll be running a separate BHA-1/BDA-1/BDP-1 rig so the whole connection issue isn't really a problem, but I've had a couple of customers now, and I'm sure this is going to be a common problem, one with a BP26 and another with a SP3 who want to to use balanced into their pre and into the BHA-1 direct from the BDA-1.
One of my customers has been talking to a guy who we have both used for Van Damme cables in the past and he has recommended the below splitter box, would this be a suitable solution James without degrading the signal from the BDA-1 as I think we all need to find a solution to this, here is also a link to more information with a manual with wiring diagram, cost is around £100 with gold plated sockets so not too bad really, it certianly looks the part, it's just missing a Bryston badge on the front :)

A quick look online shows a 6 foot XLR splitter cable from BlueJeans cables is about $30.00 to $40.00, using Beldon 1800F or Beldon 1508A and Neutrik gold plated connectors.

HI Brucek,
Please let me ask you to comment on these remarks made on another forum http://www.audioheritage.org/vbulletin/showthread.php?9605-balanced-cable-splitter:
"You will have no problem with a single hardwired spilt. The only issue maybe and that is a very very small maybe if by chance the preamp outputs and the crossover inputs were transformer coupled, again that is A very very very small chance."
How, in your opinion, would this apply to splitting a BDA1 signal in to the BHA1 and the BP26?
"Depending upon what you are interconneting, you might develop a loading (impedance) differential between the legs, but that is not a common result, so forge ahead. If there is a loading difference, it merely results in a gain difference - not big, but it can happen. If the loads are the same, this does not occur, particularly if you are doing the same thing to both L and R. "
Again, please reflect on the Bryston situation if you can? I wouldn't want the gain difference, as said, one of the reasons I'd opt for the switcher.
Thanks a lot ,
Marius
btw, if this splitting/switching hijacks the forum subject too much, i apologize, maybe we can take this to a separate thread.
Splitting a signal from a low impedance source to two high impedance sources divides the impedance that the source sees - not the voltage. It's not a power connection - negligible current is being drawn, so the voltage is maintained.
The only difficulty in producing a balanced splitter is soldering two wires on a pin rather than one. I have no doubt they overcharge for it though. I can't imagine a splitter box would be less difficult or expensive to create.

"You will have no problem with a single hardwired spilt. The only issue maybe and that is a very very small maybe if by chance the preamp outputs and the crossover inputs were transformer coupled, again that is A very very very small chance."
How, in your opinion, would this apply to splitting a BDA1 signal in to the BHA1 and the BP26?
In your situation you're proposing a simple hardwired splitter. No problem.
"Depending upon what you are interconneting, you might develop a loading (impedance) differential between the legs, but that is not a common result, so forge ahead. If there is a loading difference, it merely results in a gain difference - not big, but it can happen. If the loads are the same, this does not occur, particularly if you are doing the same thing to both L and R. "
Again, please reflect on the Bryston situation if you can? I wouldn't want the gain difference, as said, one of the reasons I'd opt for the switcher.
With regard to common mode rejection, it relies on exact adherence to matching impedance on both the positive and negative signal paths, and I believe Bryston equipment takes care of that. Your source and two loads are all Bryston, so I can't see where your hookup would result in a mismatch there.
With regard to a gain differential, it doesn't make much sense. I don't know any device that has different input impedance on each channel? So if the inference is that the voltage arriving at the left channel of one device would be different than the left channel of the other device - it can't occur, they're in parallel, so they must be identical.

Great,
Thank you Brucek. You've cleared up a lot of uncertainty.
I guess at least it it worth the try, and see what happens, found some nice manufactured cables for a modest price.
regarding the gain differential: I was lead to believe they meant the difference in volume with or without the splitter on the same line, and not a volume difference between both lines with the splitter. I do want the extra volume the balanced lines give me compared to the rca's, so if splitting will result in a lower volume, again that would be reason for me to opt for the switcher.
Cheers!
Marius

Hi Marius,
Here's a pic of my setup. I run the BDP to the BDA balanced XLR, dito from the BDA to the GamuT DI150. From there RCA to the BHA using Tape Out.
(http://www.audiocircle.com/image.php?id=70783)
I had the GamuT folks look at the BHA options RCA vs XLR and they thought that if you run a short RCA connection with a solid cable - I opted for a 1m Audioquest Columbia - you will also get excellent performance. Provided you use balanced for the HD800 cord itself. Since that is 3m vs. only the short amp to BHA connect and thus the balanced headphone cable will have a far bigger impact. Did you try that already?
Have done only little listening so far and will report more details, but sound is great, big soundstage in both depth and width (beyond the drivers so to speak), great detail. All "out of the box" already. And, excellent comfort on my head!
While I will try some balanced between the BDA and the BHA later on maybe, when I have time over the Christmas period perhaps :) and when everything is run in, I feel that inserting some switches or splitters into the chain can't make the chain stronger but rather weaker? So would try the headphone connection balanced first and then see. I think even James goes RCA from the amp to the BHA. And btw, if I have the BHA volume control between 9-10 o'clock using the low gain setting, it's almost too loud to bear already ... a lot of punch there!
-
wow thank you Joker,
beautiful it is.
Yes I will try the balanced hd800 cable when it arrives. Take your advice to wait for other insertions into the system.
Must say that the difference between rca and balanced on the BHA was quite substantial to my ears, so hope to keep that. Problem is i also want to keep it balanced to my BP26....at least for now, maybe the balanced hd800 cable will take away my worries.
Agree that the volume isn't the issue, Rca is indeed loud enough, but I felt other soundqualities came more to my ears in the balanced connection.
Thanks,
Marius

Looks like we may be getting somewhere on the whole splitting from the BDA-1 is concerned, let us know how you get on Marius, as like you the extra headroom balanced gives is one of the real appeals of staying balanced throughout.
What is the general consensus regarding balanced from the headphones to the BHA-1 as I'm just about to approach someone to make some balanced cables up for my HD800's and LCD2's, I take it is better to use the separate left + right balanced outputs compared to the stereo output?

Vipers, I had the same dilemma, but every forum I went to, I found that from an Audio point of view, left + right and stereo are 100% identical. I asked Bryston technical, and they replied same thing. So I went with a 4pin stereo for convenience. I don't know if besides audio, maybe I'm missing some other advantage not having the dual 3pin ?

I would think the dual 3 pin would allow for easy troubleshooting if one channel had a problem. Not the case with a single connector type. Since headphone cables are stressed more than regular cables, perhaps channel problems would crop up, and you'd like to eliminate the possibility that the headphone amp was the culprit.

I would say you're right , but only in case of non detachable wires, as for my HD800 I could alsways flip the left and right cable in the headphone to pinpoint the problem, but I have also AH-D7000 terminated also with 4pinXLR stereo, and if I had issue, I would be better like you say to find the problem. So maybe to play it safe, dual 3 pin XLR, also while looking for some headphone amps before getting my BHA-1, I found some amps had only dual 3 pin XLR and not the stereo 4pin. That might be another reason for versatility.

Marius, you missed one option out, Buying another BDP-1/BDA-1 combo solely for the BHA-1 :wink: All of a sudden all the other options seem pretty cost effective :)
You are right though, it really shouldn't be this hard to have a 100% Bryston balanced system, especially as there really is only one source to consider.
I think I'm more tempted by a switching box rather that the cable splitter to be honest, my customer has gone for the Monacor solution but he has specified gold pins making the total £100 so I'm waiting to get some feedback but that does seem like the safest solution.

Thanks zeiter, that's really interesting as I really would have thought that the separate Left and Right outputs would have been the way to go, makes you wonder why we have 2 options then.
I'm going to contact a company called Toxic Cables next week to discuss maybe supplying me balanced cables for my demo headphones as my HiFi Man HE-500's and HE-6's arrived today and it seems crazy not to run them balanced, so it will be interesting what they recommend, here's Toxics website, they seem to do a good variety of cables for all the top end cans -

Hi Paul,
Am considering the option of the new version2 set......
Please let us know what your findings are with the Monacor, i ordered the 2 tbl splitter cables to test. Hope to compare them soon. Got this nice test scheme setup, cause on the bp26 I've found out that playing the BCD1 over a balanced direct connection, or over a balanced connection over the BDa1 to the BP26, there's no volume/soundquality difference what so ever. Turning the source selector from bal1 to bal2 in fact leads to no audible difference. If these two new splitter cables hold up to that, i'd be happily surprised. Anyhow, a good and safe reference it will be.
Will let you all know.
Thanks,
Marius

Hi James,
Just read the manual..... in it you state the locking XLR's are already an option. Had I known that, I would have ordered those. :duh: :duh:
Is there a way to retrofit that? Or exchange for a factory delivered lock-version would be even better?
Thanks, Marius
We could offer locking as an option I guess. Most of the new amplifiers do not use the locking.

Hi Bob, enough of music recos here :D but you might love Melody Gardot "Worrisome Heart" and Curtis Stigers "Let's go out tonight" then as well.
I find it just amazing how the BHA-HD800 combo delivers from single voice / piano over small "combo" to large symphony orchestra!
-
Indeed!
Melody's "Worrisome Heart" was the CD that convinced me to follow the Bryston path in the first place, a BCD/B100 at the time (her latest CD I find extremely disappointing).
The BHA takes this to another level completely, almost makes you want to reach out and touch her.

Hi James,
fiddling with the crosstalk on the bp26, suddenly i realized that other than connecting the bha1 to the tape-to on the bp26, I could connect it to the rca outs on the BDA1 also. Missing the analog sources in that case of course, but there would be no need for the bp26 to power up.
Would there be any difference between the two choices? I'd be tempted to believe that 2 machines less, would mean a better signal?
Thanks,

Marius, bobNL or anyone else with a BHA-1 and HD800 combo I've got a quick question if you don't mind.
Over the last few weeks I've been running in all my new headphones for the shop and this evening I thought enough was enough and I had a little shootout, HD800's v LCD-2, both cracking headphones with very different personalities, but it was more the BHA-1 I have a question on, I'm using high gain fed by RCA's from a Naim streamer at the moment, until my BDA-1/BDP-1 pairs up with the BHA-1 when my version 2's arrive, anyway, on the BHA-1 I found that when moving the volume from say 9 o'clock to 4 o'clock there isn't much change in the overall volume with the biggest change happening in the last 10%, does anyone else find this? in fact with the HD800's and LCD-2's you have to be on almost maximum volume to get what I call a good listening level, and with the HiFiMan HE-6's there really isn't enough volume to drive them properly.
My BHA-1 has had a problem in the past and I'm wondering if this lack of apparent volume and subtle volume control is correct compared to others? or I guess I may just be deaf :)
What volume do most people listen at?
Cheers,
-
I had same result as you , almost nothing happening at all in that range when I had my HD800 ( just sold them ), and I thought it was due to the 300 ohms impedance. I did not have this problem with my Denon AH-D7000 as they were 25 ohms, and I think 107 or 108 db sensitivity, so by 9 position, had plenty of loudness, and did not need to go higher. I just received yesterday my LCD3, and put them on burn in with my BP6 pre, as I did not want my BHA-1 to run very hot for a couple of days, can't comment on them yet in that range.

Hi Vipers:
I have the BHA-1 and HD800’s and on low gain and balanced (stereo 4 pin) and I am set at about 9 o’clock listening to Eagles Hotel California right now with plenty of volume. I tried single ended and I then needed to move up to 10 o’clock for similar volume level. I think the balanced output is just awesome compared to going single ended which is still very good. To me the BHA-1 and HD800’s are a match made in heaven. I temporarily have no loudspeakers until my Bryston Signature Edition Model T loudspeakers are delivered so I’m spending plenty of time listening on headphones!!!
BTW I have read with interest your new venture and admire you for taking the plunge. It is a long time ago but I used to live in Harpenden working at Imperial Chemical Industries in Welwyn Garden City, Herts. No stores like yours when I left England to emigrate to Canada in 1967!!! Good luck with your store!
Cheers
Extra Information
Sorry but I should have mentioned I am running single ended Canare interconnect 12 metres from the tape monitor of my Moon P7 preamp to the BHA-1 on my desk. I wondered if i would have to tear my house apart now to put in a balanced interconnect but i know it would be better but the single ended works so well I hate to renovate!
-
Hi Vipers,
Use the single ended headphone out and my BDA is connected to the BHA by XLR interconnects. With this setup, and the low gain setting, anything above 9 oclock will blow my eardrums to bits. My BCD is (also) connected to the RCA so I gave that a try. I agree, in the low gain setting nothing much happens between say 10 and 2 oclock. When I switch to the high gain setting volume increases (for obvious reasons), but it is also more responsive tot any turning of the volume knob. Perhaps RCA works bettter with the high gain for some reason.
Never noticed this because I mostly use the BCD through the BDA.
Looking forward to a new balanced cable for my HD800's. Am also interested in your experience with the BDA2 (hope its not much better than the BDA-1).
Cheers,
Bob

I'm running XLR from DAC to BHA-1, with HD800's using SE output. BHA-1 is set on low gain. Volume above 9 o'clock is too loud for my ears.
Rick
-
Hi Vipers,
My BHA-1 is fed the analogue signal from:
- the RCA out of my BDA-1 to which my BDP-1 and BCD-1 are connected
- (additionally), balanced XLR directly out of my BCD-1
I just toggle between 'RCA' and 'Balanced' as source on my BHA-1.
I don't have my HD800 with me because I had loaned it to a friend. I use a balanced (4-pin XLR) HE-6 instead, which is a more diifcult load than the HD800. On either 'RCA' or 'Balanced' setting on 'source' on the BHA-1, I set the BHA-1 on 'high gain' and listen mainly with the volume at between 9 and 10 o'clock. This is already sufficiently loud for me.
Hope this helps
-
HI Vipers, Paul,
I've noticed a similar volume sensitivity: from about 7 to 9/10 o'clock the volume increase is about the same as from 10 to the max. Using SE in- and output right now. Hi gain gives a bit more spice, but the volume increase-Delta is about the same. I find the setting between 10 and 12, of course depending on source material, most comfortable.
I've noticed also, that like the BP26, the BHA1 still plays very softly, when volume is 0%..... So where Bryston technicians tell me that this issue is caused by total gain in the Amp-chain, (and the amps might be too strong for the speakers, 28b's and ESL63 in my case) the BHA1 causes this on its own....
Curious to notice that apparently the HD800 is so very sensitive it plays music with voume at 0%, and still the difference between 10 oclock and later is so very small :scratch:
James, care to comment please?
Cheers,
Marius
Ps will check this when my balanced cables arrive.

Thanks for the replies guys, seems to be a difference of opinion there, my findings are very similar to Marius's, I almost wish that at 9.00 o'clock it blew my ears off, it takes until I get to 95% to achieve that.
I think what I need to do is put it in a 100% Bryston rig and remove the Naim streamer and give it another go, I'd imagine balanced from the BDA-1 will help no end.
I'll give it a try tomorrow and see what happens.
Thanks again.

Hi Vipers:
Just out of curiosity I took the output of my BDP-1 / BDA-1 single ended via my 12 metre single ended Canare interconnects to the BHA-1 with much the same 9 o’clock setting single ended and 10 o’clock balanced volume settings for more than enough level just as I found when taking the signal from my tape monitor on my Moon P7 preamp.
I’ll be really interested to hear your results when your gear is set up the same way as the above. Your only difference will be a much shorter interconnects to the BHA-1 which could only be beneficial. I have to have the 12 metre interconnects unfortunately.
Interestingly I believe the sound directly out of the BDP-1 / BDA-1 is a little more spacious and dynamic than when I take the signal out of my tape monitor on my Moon P7 preamp. This requires more listening time to be sure but I’m glad I tried it.
Cheers,
Roger

HI Paul,
did some more earwork, and adding to the previous, I hear a sudden volume-increase between 4 and 5 o'clock.... approaching your 95%, because then it is too loud definitely .
keep us up to speed with your findings please.

Excellent review James, you couldn't ask for much better against the established competition the BHA-1 was up against, I particularly like the below ideas though, time to get your R&D department doing some overtime :) -
'I'd like to see Bryston introduce another model sitting above the BHA-1 with multiple balanced inputs, higher maximum output, a remote control and a volume control covering a wider range of output levels.'
-
Thanks again loopyground and Marius, Hopefully this afternoon I will get a chance to move my BCD-1 into the headphone room and do some furhter experimenting as at the moment I have to say that my BHA-1 isn't capable of driving my HE-6's at a volume I find listenable.

Hi Vipers, pls see my posting #450 here that documents my setup. In your case I assume the Naim source might be the "gap". The "problem" with these components is the vicious circle you create: you need to spend a lot on cabling to really unlock the potential of all these components :D
-
Hi Joker, thanks for that, I seem to be getting somewhere now, and yes looks like you are right, RCA's from the Naim streamer into the BHA-1 certainly seem to be holding the BHA-1 back, normally I wouldn't mix Naim with Bryston but it seemed like a good source to feed all my headphone amps which it seems to be other than the BHA-1.
Just now I took my BCD-1 and plugged that into the Balanced inputs of the BHA-1 and queued up the same song on the Naim streamer and one the BCD-1 and flicked between the RCA and Balanced selector, leaving the gain on high for both, WOW, what a difference balanced from the BCD-1 was, massively louder but also far more clarity and detail, it was a different league. Also when using the balanced connector from my HE-6's it went up another level, a fully balanced BHA-1 really is something quite special, which makes me realise that I need to sort balanced cables pronto for my LCD-2's and HD800's to really hear them at their best with the BHA-1.
So progress made, but there still isn't much improvement in volume between 10-2, but I guess that is just the way the volume works on the BHA-1?
Thanks.

Hi Vipers, I hear between 9-10 max. Beyond that I'd be afraid my ears would blow away ... and I feel I'm hearing loud already.

Hi Vipers and Joker:
Just measured the level at 9 o'clock setting with my meter (between the drivers) set on slow response and C weighting and that gave an average of 70dB playing Eagles Hotel California. At 10 o'clock more like an average of 80dB which is way too loud for me. I now going single ended from my BDP-1 / BDA-1 to my BHA-1 and 4 pin balanced into HD800 'phones. Previously I took the signal from my preamp tape monitor but found things sounded more spacious and dynamic directly out of the BDA-1. This is likely because of a slightly higher level. 9'oclock now gives an average of 70dB and is now too loud for me and I'm an old fart!!! Comfortable listening level on this track would now be closer to an average of 65dB and slightly below 9'oclock.
Cheers

Bravo!!! Once again I am happy to see my BHA / HD800 choice confirmed. I couldn't agree more with the findings and I think, James, that readout (incl. Otwin's additional forum comment) WARRANTS a translation!
P.S.: maybe James you did overlook my earlier question regarding the power consumption of the BDA and BDP? Since Bryston now specifies that I think first time with the BHA? At least I didn't see it yet for the other two fine components I own from lovely Bryston. Thanks!

Great review!
Well deserved, still happy as a bunny with the combo :hyper:.
They have also connected the BHA directly to some active speakers.
Abacus, never heard (of) them but the reviewers seemed happy.
Anyone have eperience to share on using the BHA as a preamp?
Still considering a B4SST2. If only it had a mute button :|.

Hi Bob, when I first got my BHA-1 I hooked it up to my 4B SST2 just to see how well it worked and it really surprised me, I've not had much experience of the BP6 or 16, only the BP26 and SP3, so I'm not sure how it compares with a dedicated pre and where it would slot in regarding performance in the Bryston range, but to me it sounded brilliant. The BHA-1 really is a Bryston bargain as being able to use it as a pre and a reference headphone amp makes it a steal, even at UK prices :)

Being a huge PMC fan and very unlikely to get to hear the Model T's for some time I would love to hear your conclusions on that little shootout Bob, I know the Facts extremely well and speaking from experience they are an amazing speaker that works brilliant with Bryston but having read all the great comments regarding the Model T's could make it a very close call.
Please keep us posted Bob when you do audition both speakers :)

Hi Paul,
Suspect the model T’s are "on their way" across the atlantic. Have heard the Facts before and was much impressed. As I tend to play at relatively low volumes I especially liked their dynamic nature. They are also quite pretty to look at. Although I have high expectations of the model T's, the looks will not be their main selling point. It will be difficult for them to hide in my room, the PMC's will likely be better at that.
If it wasn’t for the appearance of the Bryston speakers on the market, I would have bought the Facts some time ago. However, my admiration for our friends from Canada is such that I do not want to buy speakers before I hear the Bryston (Tanner) take on speaker design.
Have reached headphone nirvana (maybe a Cardas balanced cable for the HD800), but would like a similar experience with the speakers.
Will certainly keep you posted,
Cheers,
Bob

CONCLUSION:
"Now forget my small reservations and let’s recognize an outstanding bargain in balanced headphone amps.
If the Bryston sold for $2500 I would not have been surprised and it would still offer strong value. At its current price it is a steal.
Buy one today."

Can't blame you for the Bob, like you I admire both PMC and Bryston equally, it is thanks to both those brands that I rediscovered my love for music, and if I was on your side of the pond I would have to audition the Model T's also as all the reviews I've read have been unanimously positive.
Between you and me, I wouldn't be surprised if we see a new addition to the fact range early next year also, maybe worth bearing in mind, only a guess but keep it quiet though :wink:

hi,
Maybe off topic, but since we're all talking hd800 also here, please forgive me: my dealer called to say the extra hd800 cable to make into a balanced cable with 4pin neutrik is delayed, since it apparently is made of some special material, coated with teflon :scratch: seems to make the process of soldering somewhat difficult and they have to test before shipping to the customers. I love this dealer responsibility, but regret the extra time to wait and be able to enjoy the balanced BHA1 outputs.... :cry:
Anyone with a handmade balanced hd800 cable that had any difficulties?
Cheers,
Marius
btw James, got an agreement with Mafico on a special order BHA1 with locked rear XLR's, I hope you'll find in your orderbook soon :thumb: taking the proverbial customer-care to yet another level of greatness. Should we be surprised with this at Bryston? No. Are we glad we chose Bryston: YES! Thanks.
-

Lol, it is, as was my Garage.... even found some handmade cabling, that didn't make it to Sinterklaas' quality-standards in the end.

Hi
As long as your headphones have 2 cables coming from the ear cups (1 wire from each) you can simply remove the 1/4 inch phone jack at the end of the cable and replace it with a 4 pin Balanced XLR connector.

On Friday last week I received the demo BHA-1 from AViTech (Austria) who is responsible also for Germany.
After long hear-sessions, I've ordered this morning, a BHA-1 without integreted power-supply at my German distributer. :D The powersupply MPS-2 of my BP-26 will supply my new BHA-1.
It sounds so phenomenal. I've heared so many details the first time. I'ts not describable in words...
My setup 1:
Source: Cambridge Audio CD840 digital out. ==> BDA-1 ==> BP-26 Bal-In ==> TapeOut of BP-26 ==> BHA-1, RCA in ==> AGK-701 or AKG-702 on my ears
My setup 2:
Source: Pro-Ject Xperience with Ortofon M2-Bronze ==> BP-26 MM-Phono-In ==> TapeOut of BP-26 ==> BHA-1, RCA in ==> AGK-701 or AKG-702 on my ears
I'm a little bit sad, that I must send tomorrow the demo device back to AViTech... :(
I will report when my ordered BHA-1 will arrive. In the meantime I will use the time to modify my headphones so, that I can use the symmetric output of the BHA-1.
I'm so happy :-))

Hi Ralf,
Glad you liked the BHA-1 :thumb: I might suggest getting the unit with the built in power supply though. There is no difference in performance between the external and internal supply versions and having the internal supply makes it so much more convient to move from location to location and now that you can use it as a preamp even more flexibility. Not to mention resale value.
james
-
James,
The Bryston website pictures of the BHA-1 still shows the unit without the rear balanced outputs. Is there any chance that there are dealers with stock of that version and how would one determine the version of a new in the box BHA-1 without looking at it? Do you know the serial number of the first BHA-1 that had the rear balanced outputs?
Tony

Any serial number over 50 has the Preouts - we actually started shipping preamp versions months ago but held off having to raise the price as long as we could.

Hi James,
For me, the headphone amplifier is the logical extension of the basic unit BP-26, just like the phone amp PB-1.5 or BDA-1/-2.
From today's perspective, I'm not going to separate the headphone amp from this chain.
In my view, the external BHA-1 eliminates the only weak point of the BP-26.
Your objection to the higher resale value is absolutely correct. But in my case I do not speculate with the device. I only want to enjoy the perfect sound of the music. The BHA-1 gives me the possibility and this for many years :-)
The Bryston motto "Music for a Generation" is not just a clever ad copy, this is the core statement of your products. I would not buy a product with a short lifetime or short useful life. What counts is perfect sound and long-lasting quality. It takes a long time until I decide to buy one, then I am also sure that this is exactly what I will use in the coming years.
Ralf
-
Is there any sound difference after using the BHA-1 for 100 additional hours?
I know, it has already 100 hours of burn-in before delivery.
Best amp for headphone i have ever heard (using K1000, TH-900)!

I have noticed no change in sound since i've owned the amp for 2 months now.

Hi Hubert381,
Sorry for the delay in your response. I assume the balance control is there for recordings that have too much emphasis in either the left or right channel which would be done when creating the master from the studios - with this balance controller you can balance or level-off the soundstage from left to right so the listening becomes more natural.
I have never had to use this feature before but, i understand it's purpose.
That's my take anyway and hope it helps explain.

I see on the Bryston website that a table of new specs has been added for the BHA-1. But nothing listed for the output impedence of the headphone outputs. I'd really like to see the output impedence listed as part of the specs, so that I know exactly what I'm working with before I buy.

Very excited about the BHA-1. I am a long-time Brystonophile -- I have the BPA-26 (w/MPS-2) & 4BSST for my living room setup. In my office I currently use a HeadRoom Max Balanced Headphone Amp which I use with balanced AKG-701s and also connected to a pair of Dynaudio BM6 MKII monitors for nearfield listening. I have a Transporter for each setup (purchased in Bryston's pre-digital era).
The HeadRoom amp is really a wonderful piece of kit -- it's been on pretty much every day for the past six years. Sadly, it's been discontinued and I'm delighted to see Bryston step up and fill this gap. I think every music lover should have a high-end balanced amp like this. Nothing beats it in terms of $ per audio quality/listening enjoyment.
I was really pleased to see that you added a pair of Balanced Outputs to the back of the BHA-1. However, I noticed that there isn't a switch to turn the rear output on and off. It's kind of nice to have this to switch to a headphone-only mode without having to reach around and turn off the monitors. Just an idea for your next rev.
Anyway, congratulations on what looks to be a beautifully conceived & executed product. I can't wait to get my ears on one.
Best,

Hi all,
So, has anyone tried the BHA as a preamp? Impressions? I cannot try it till next week when my new speakers are finished being built. May sell my BP26 to fund the BDA2 if BHA compares or exceeds the BP26 performance.
Thanks in advance,

Having no remote with volume control is one of my annoyances with the vast majority of headphone amps. Maybe there's others, but the only ones I know of that do offer remote option is Grace m903 and Benchmark HDR. I hope Bryston adds it in the future.

Hi James,
I'm considering consolidating a B60 I now only use for headphones and a CJ PV5 preamp from a seperate system. I'm considering a BHA-1 for use as a preamp and headphone amp because I'm listening to headphones much more and won't need the CJ because I am getting out of vinyl. My amplifier has unbalanced inputs. Can I use xlr to phono adapters on the BHA-1 rear outputs and also does the gain switch on the BHA-1 effect the rear outputs? Since the BHA-1 seems to be being built to order, can a BHA-1 be ordered with unbalanced rear outputs? Thanks.
-
Hello James
Is it possible to get a BHA 1 with a mono switch like on a bp25 or 26?
-
Hi James,
Can I use xlr to phono adapters on the BHA-1 rear outputs
No problem with adapters
and also does the gain switch on the BHA-1 effect the rear outputs?
Yes it does
Since the BHA-1 seems to be being built to order, can a BHA-1 be ordered with unbalanced rear outputs? Thanks.
No sorry that would require a different chassis.
-
Thank you, James!

Well Ive had my BHA-1 for about a week now and I must say this amp is Fee-freakin- nominal :). I am running balanced from source to preamp to BHA-1 and I'm running the LCD-2 headphones with a balanced cable as well. This combination is a match made in heaven to my ears. Perfect tonal balance, super deep taut controlled bass, detailed fleshy midrange and smooth treble. I can hear every nuance and texture in voices, strings, synthesizers, drums or any instrument. The emotional content of the music just seizes you because of this. PRAT? You better believe it! Such a relaxed, natural, rythmic flow to the music....Its so intimate, so real and vivid..... just sublime. This is by far the best headphone/amp combo I've ever owned. The LCD-2s sounded great out of my McIntosh C50's preamp headphone jack but they're in another dimension now. I have the Denon AH-D7000 headphones as well but they're out having the crapp headband swivel repaired. I'll report back on how they sound. My little Grado SR80s sounded terrific and were pumpin the bass...lol. Anyway nothing but praises for the BHA-1 !! If you want a stellar combo pick up the Audeze LCD-2s to go with the BHA-1.
-
I am going to look into this more Greg.
James
What was the result of this investigation, please.

What was the result of this investigation, please.
It appears that units up to SN 100 could be either version depending on the chassis.

BHA-1 in the house! After exhaustive reading and research I bought the BHA-1 on faith, which is very, very rare for me to do. I have never listened to a dedicated headphone amp before today when I listened to my BHA-1 for about an hour. 'phones are Beyerdynamic DT250-80 which to me seem very neutral. I only recently started listening to headphones and didn't want to spend a lot without auditioning. I had a chance to compare the DT250-80, DT250-250, DT880 and a Sennheiser model of which I forget the number all at the same time and was impressed enough with the 250-80 that I purchased a set.
I have been listening via a B60. Initial findings reveal the BHA-1 is cleaner, crisper (not brighter), more detailed, has fuller bass, better separation, more sense of space around the instruments and what I like most of all, the improved sense of attack and speed of the music. (Did I leave anything out?) Inputs and outputs are unbalanced. I have balanced cables on order for the source and I have also ordered xlr to rca adapters so I can use the BHA-1 as a preamp. More to follow once the adapters arrive. I know several are curious about the BHA-1 as a preamp.
-
I am currently using the BHA as a preamp in comparison to the BP26. So far they are both very close to the same performance and cannot identify yet much differences, i'll keep posted when something new should happen with my findings.
Both BP26 and BHA1 units are substantially broken in.
System consists of: 4bsst2, BP26, BCD1, Oppo105, BHA1, Martin Logan Montis loudspeakers, Torus AVR15 and all cabling is Cardas Clear throughout.

Mark - would be interesting to get your take on how the BHA-1 compares to the 105's headphone application...

Hi Ron,
I did test the BHA and the Oppo 105's headphone output a few days after receiving it and letting it run in for 4 days. It only took about 1 song to realize that the BHA is far more superior even though the 105 has the infamous Sabre DAC in it. The sonic performance resembles the same as plugging in headphones to a preamps headphone output - I have to admit I was a bit disappointed as Oppo go on about it like it's the holy grail but, for me nothing special. Another thing to remember is that the OPPO has its own volume control so i had to using both - set the OPPO to max and then used the BHA volume to the level of your choice. The detail was as good as Bryston as well as all the layering of bass notes and ambience just no impact or dynamics when used as a headphone amp. I have not used the Oppo for music since but, really bought it for the Bluray capability that all the big dogs apparently are cloning. My new 70" Sharp LCD Elite comes in tomorrow so I will check out it's video performance as my TV demands top notch processing and scaling.
If you're using CD's as your medium then I would stay with a dedicated cdp and leave the Oppo for home cinema and live concert duties. This unit does a lot for its money and is worth it but at the end of the day it is still only a $1200 universal bluray player.

Hi Guys,
Are there any HiFiMan HE-6 users out there with a BHA-1?
I've had my HE-6's for a couple of months now, and obviously they are considered the toughest headphones to drive on the planet, the best I have heard them sound is on my fully balanced BHA-1/BDP-1/BDA-1 set up and they sound excellent and can be driven at a reasonable volume, but I've still got a niggling feeling that I'm still not quite getting the best from them.
So I've just got this HiFiMan little black box in, Its called the HE Adaptor and it lets me power my HE-6's direct from any power amp, obviously I'm thinking Bryston here :) Is it considered overkill to power a pair of headphones direct from a pair of Bryston 7B's :icon_twisted:
I can't wait to try it later, hope the headphones don't melt though. What I am really trying to achieve is to see how good the BHA-1 is at driving the HE-6's as it seems to do a stellar job but at least this way I can hear them at their max then try them on the BHA-1 and see how it compares, if the BHA-1 can drive the HE-6's as well as the adaptor then that is really saying something, it's almost the ultimate test of the BHA-1.
Hopefully I'll get a chance to test it out later.

From Audeze support :
When deciding what amp to buy It is very subjective and opinions vary a lot. Here are some thoughts on selecting a good amplifiers for LCD-2. We have tested the LCD-2 with quite a number of studios and recording engineers. The LCD-2 has an impedance of 50 ohms, which is purely resistive and is almost perfectly flat across the entire frequency range.http://www.audeze.com/2009/12/waterfall-plots-low-frequency-extensi... Lets us say you listen to symphony-orchestra. This type of music can have dynamic range of 60 dB. i.e if silence (room noise) is at 60 dB (LCD-2 is pen type headphone design with almost no attenuation of ambient noise) and the maximum occasional peak needs to be 120 dB. I am just giving an example here, but depending upon the type of music and the recording this varies. 120 dB is very loud - almost Rock Concert level close to the speaker. For the LCD-2, if you put 1 mw of power, you get about 90dB output. For this example, let us assume 90dB is the level you listen normally. To reproduce the occasional 120 dB peak without clipping on the LCD-2, the amplifier would have to output 1000 times more power than 1mw, i.e 1 W. So, an amplifier that can output 1w is the bare minimum. Amplifiers will have distortion metrics at different wattage levels. If an amp can output maximum 1w it would be barely sufficient and might have a lot of distortion at full output. So I would suggest an Amp that would at least be able to provide a couple of watts of output without any clipping. Damping in amplifiers is not a big problem for LCD-2 since the impedance doesn't vary.
Now I know the BHA-1 has 0.5 w of nominal power at 50 ohms, which is 1/4 of what's mentioned above for the LCD2. Yet I drive my LCD3 at volume between 9 an 11, and find that really loud, and do not need anymore. But am I missing something like more headroom or something else if I had that extra power ?
-
The writer lists 2 different headphones -
The Audeze website listing for the LCD2 claims a sensitivity of 91dB @ 1mW and an impedance of 60 ohms and the LCD3 claims to be 50 ohms and a sensitivity of 93dB.
For 120db SPL it will require about 1000mW for the LCD2 and about 500mW with the LCD3. The BHA1 will still have 10dB of headroom at these levels.
The BHA1 is rated at a load of 32 ohms and an output power of 500mW with distortion typically at 001% 20 to 20kHz.
At 2000mW the BHA1 distortion into 50 ohms is typically less than .004% and will not reach 1% distortion until it reaches 8 watts output or 130 db SPL.

Are you using the balanced output connections on the rear pannel to connect to your amp via balanced cables? And... are you using a balanced source to connect to the balanced inputs on the rear panel?
My BHA-1 has the balanced output connections on the rear panel, but the manual doesn't show them, nor does any technical info on the mfr's web site. I assume they've been added without an update to the manual. And... I assume they're used to connect to an amp to allow use of the BHA-1 as a pre-amp. But, I've seen no confirmation of that anywhere.

Hi
Yes the rear balanced outs are in parallel with the fronts and allow the BHA to be used as a preamp - a mighty fine one I might add :thumb:

Well... then I'll be trying it out as a preamp to my amp driving my KEF LS50's (phenomenal speakers) - but, I guess I'll have to get some balanced interconnects to do so.
I've also been impressed with it's performance into my Grado PS1000's and RS-1's - possibly the best amp I've had to drive them.
Though, the WA 6SEm and the Burson Soloist are also superb... the BHA-1 may have a slight bit more resolution, while the others have great PRAT, dynamics and weight, which may be a slight bit better than the BHA-1. Finese vs Power... I guess.
-
Hi Gradofan,
Agree that the combination with Grado cans is great, own the GS1000 myself.
There are many members that are interested in the BHA-1 as a preamp.
Please let us know, when your interconnects turn up.
What poweramp are you using?
Cheers,
Bob
-
Just want to say that I am very pleased with the capability/flexibility added to my system by the BHA-1. I have the BHA-1 inputs set up as balanced tape loop from my preamp and single-ended from my BDA-1. The BHA-1 output is to a single-ended amp (driving outdoor patio speakers) using female XLR to female RCA adapters. With this arrangement I can control the volume of the outside speakers separately from the volume inside and play different sources inside and outside at the same time. The BHA-1 works perfectly as a preamp and gives me good sound quality outside driving my Bose :peek: outdoor speakers.

After owning a BHA-1 for a couple of months, I agree with most of that review.
I'm not so sure about the benefits of recabling my Grados for using balanced ... they sound great single-ended

HI James,
Today received my BHA replacement, and this unit behaves differently form the former at power-up. The former had the power-led light red and when fully charged turned green, as all my other amps do (power, and pre-amp). This new BHA is green instantly though, did Bryston change the circuits in anyway to allow for this?

Hi Marius,
My BHA-1 also goes to green instantly at power on which is what the owner's manual says it does. If you were using an external power supply and the power supply was on and BHA-1 was off the LED would be red.

My BHA-1 goes red to green in the same manner as my 7BSST2's. However, the duration of the red indicator is less than that of the power amps.

Hi James,
Strange and unexpected as it may seem, the most missed feature of the BHa1 in my setting is the remote volume/mute control... The br2 would do fine!
Is there any chance Bryston is going to update the BhA with this option?

+1 on that. Remote volume control is greatly missed due to the different volumes of CDs.
Tony
-
+2. A lack of remote control volume is IMO a great failing of almost all headphone amps. It seems like manufacturers assume that I want to sit right next to my headphone rig. I don't. So Grace m902/m903 becomes one of my only options. If Bryston starts including a remote volume, I will buy BHA-1 almost immediately (if funds allow :duh:)

The same goes for me. I want to use it as a regular preamp as well, but no remote is a no-no for me.
-
I am on the cusp of buying a BHA-1x (no inbuilt power supply as I already have an MPS-2 with my BP-26) but the absence of the remote control facility is a problem.

I would think twice about the no internal power supply as resale will be nearly zero. Think about it, you will be limited to sell it to people that have an MPS2 only. :scratch:

Hi James,
Is there a way to have the gain reduced on the BHA? The reason I ask is because the volume is very sensitive on mine. If 7am on the dial is no volume then at 8-830 it is very loud. This is with listening through speakers. My 4B gain is at the lowest setting.
Thanks, Mark

Hi All,
Just signed up to post after having lurked for a while in the lead-up to my purchase of the BHA-1 a month ago.
I've found an issue similar to that described by Vipers and Marius a few pages back. Emailed James on the 2nd of March and have followed up once since, with no response received. Just wondering if anyone else has had similar issues and if Vipers/Marius read this, did you get anywhere in investigating or speaking to James/Bryston about this issue?
Re my issue, details of my email sent to James on March 2nd below.
Hi James,
Just stumbled upon something random with my amp which seems to be what a few others have found too.
http://www.audiocircle.com/index.php?PHPSESSID=iaat7supes1ddms77uaavbe483&topic=104028.msg1160641#msg1160641
This concerns a strange lack of linear volume increase on the knob.
Following the previous email re hearing some very faint music at 0%, when I was experimenting tonight by turning my DAC volume down and bumping my amp volume up, I found that the sound increased to about 80-90% max volume with the knob turned up till around 9/10 o'clock. Turning past this point yielded virtually no perceptible gain in volume until approximately 4o'clock. From approximately 4 to 5 o'clock the amp then boosted it's volume audibly.
Why is this happening and is it normal?
In normal usage, whereby my DAC is at max volume, I've never faced this issue as I've only ever needed to go to 8-9o'clock on the amp for more than sufficient volume.
Thanks,
Nick

On a more random/administration note, why is this thread not stickied like the other Bryston product threads?
-
So I read somewhere that James has added a pair of HD800s to his personal collection. How do they stack against the PS1000 with the BHA-1, I wonder... :icon_surprised:

HI
Its interesting because I am learning that there are firly large differences in headphones - I guess much like speakers :wink:
Anyway the Grados are much more balanced towards the low end so very full and deep. The HD 800's sound more linear to me but at the expense of sliding towards revealing the shortcomings in the source material.

Forum admins - as per my previous post - could this thread please be stickied like all the other Bryston product threads.
Further to my previous post regarding my issue surrounding uneven gain in the volume knob, does anyone else have the same issue or has anyone else even tried to test the scaling of their volume?
Quite simply, if we express two factors, one being total volume output (V) and the other being total physical rotation of volume knob (P), normalised from 1 to 10 with 10 representing the maximum, what has been observed is that:
- Where P is between 1 to 4, V scales from 1 to 6
- Where P is between 5 to 7, V scales from 6 to 7 (if at all it changes...)
- Where P is between 7 to 10, V scales from 7 to 10 (audible but not as strong as the first scenario)
It has taken 11 days and myself following up twice, as opposed to their usual 1-2 day response time(to his absolute credit, James used to respond extremely quickly - within hours, even during non-business hours), for them (James was unresponsive before I copied the same email to Brian Russell who eventually chased this up with his engineers and responded to me) to tell me in literally one sentence that uneven gain across the volume knob is normal.
I'm not entirely sure why this design is as such and would love to see if anybody else with a BHA-1 has the same experience as it just sounds rather peculiar to me.

Ahh, thanks Steve. Fairplay, it did seem incredibly odd that James had slowed down. I guess it wasn't obvious and I figured looking at this activity and timestamping around the place here that he was still active.
Anyway, posting on another audiophile forum online, a couple of people have told me that such uneven gain in volume is actually normal and part of a logarithmic pot + something that Bryston itself advertised somewhere re the BHA-1. Anyone have any knowledge of this?
I certainly don't profess to be an expert but from my experience trying quite a few different mid/high end amps, this kind of uneven gain doesn't intuitively feel right. Happy for anyone to lecture me otherwise.

Ah, makes sense. It totally doesn't sound like the ever-responsive and friendly James that I've dealt with to date, letting something go for a week ;) Hope you're better.
Have been speaking to Brian Russell who is following up with the engineer(s) but so far, it does appear that it is indeed a function by design.
Thank goodness there's enough volume for me to never even hit/pass 9 o'clock, this isn't really an issue. I just wanted to make sure I didn't have a defective unit. I still do maintain the opinion that this kind of uneven gain is weird.

I don't want to speak out of turn as the engineers know better than I but I believe we were concerned that very efficient phones would need lots of range to adjust for volume so the volume control is not linear. Also I am told this approach benefits from a lower noise floor.
James
-
Hi James,
That seems justification enough, thanks for that.
Elaborating on this topic just a bit, how would you explain that in my BDP/BDA/BP26/28B setup I can only dial up my balanced sources to lets say 9/10 oclock, before the music sounds far too loud (over my ESL63's) while the same sources over the BHA have to be dialed up to at least 11 , but mostly 14 or more, to start being groovy. I cant get it to be too loud on the BHA, gain high engaged, playing the rather easily driven HD800?
Thanks,
Marius

No, Im feeding it from the single ended analog outs of the BDA1. Planning to go the full balanced circuit when I finally receive my balanced headphone cable from Sennheiser.

OK can you try the tape Outs from the BP26 and see if it changes.
james
-
Check, I will, later.
James, there is some nuance to be applied here: the volume increase between 10 and 16 o'clock is rather insubstantial, as noted before in earlier posts. Dependent of the overall sound-level of the recording, the sound either starts to swing at 16, or already is kinda loud at 10....
My previous post obviously was made after listening to a Tallis Scholars recording, just now I tried a Miles Davis Bootleg, and that had me turn the volume control down for the first time...

I cant get it to be too loud on the BHA, gain high engaged, playing the rather easily driven HD800?
Thanks,
Marius
Whoa!
I'm using BHA-1 and HD800 as well, though in balanced operation (4V from DAC), so there's that, but most music with a dynamic range of 5-10 (most popular music) has my volume at 8:30-9:30 on low gain. Even 12 o'clock on low gain is brutally loud.
-
The volume issue seems to resolve when the BHA is connected through a balanced connection.
Had the BCD connected directely for a while, when the digital cable was under way, and had the same issue.
After rerouting the BDA through the BDA, I have rarely felt the need to go beyond ten o'clock.

Agreed. I run balanced from the DAC to the BHA-1, and anything beyond 10 o'clock would be far too loud.

finally, it arrived today:

first impressions: XLR seems to resolve the volume issue :thumb: :thumb: but most of all: gives a heavenly ambiance, lots of space, airiness in the recording. And it wasn't bad before.....
still connected unbalanced from BDA to BHA. Gain is Low.
Will try unbalanced from BP26 to BHA for James, and, of course, the very reason I bought the BHA in the first place, Balanced from BDA to BHA.

Hi Bob,
We ordered a spare standard cable from Sennheiser, and changed the connector into a Neutrik XLR, according to the schedule posted earlier.

So, in the end, it finally happened, I got to test the Fully balanced system, from source (BDA1) to HD800.
It happens to be the most influencial change made to my audio setup since the introduction of the 28B's in it. Was the unbalanced BHA a revelation, the Balanced cable to the hd800 a volume solution, the balanced connection from BHA1 to BDA1 is a uncomparable full system upgrade.
I just can not believe the change this makes, it 'degrades' the really wonderful setup before sound like a mere nice stereo headphone. In balanced operation, it is a completely different soundstage. Changing the rca to balanced makes you hear the two channels mix to the desired soundstage, and changing back is a no-go. Things really fall in place, thers one big picutre in your head finally. I now understand the raves.
I must say, I'm astonished about the world of difference. It is so compelling, the balanced connection to my BP26 is gone now. Took it out without any doubt. No brainer. Which in itself is too bad really, because right now I don't use the balanced setup my bp26 gives, and was the sole reason I chose the BP26 in the first place..
I really wish for a second balanced out on the BDA2 or 3 or some kind of other Bryston solution to let me play the BDA1 balanced to my headphone and the BP26 at the same time....
James, didn't you say before you'd be able to modify the bp26 rca outputs into an extra balanced set of outputs? I accidentally tried those today, and noticed neither the volume nor the input selector had any influence on the output, only the source-selctor on the BDA1 changed that :scratch: :scratch: Please explain what happened: I've connected the BDA unbalanced out to the Bp26 rca outs (can you believe it :duh: :duh: :duh:) No real problems occurred, it played fine over the speakers.

Hi Steve,
Thanks for your effort. We've gone over this route before though, have a look in this thread earlier on, and finally decided not to pursue. I've even asked Bryston to make me a splitter cable, but that was so expensive I didn't think it reasonable anymore.
Maybe with my final decision to have the BHA fed fully balanced, I have to reconsider.... It really is amazing.

Whilst I would certainly prefer to purchase a BDA-2 (if it had two sets of balanced outputs), as this seems unlikely what would be the disadvantages (if any) of achieving a similar result by running the balanced output from my BDA-1 to the balanced input of a BHA-1 (which I have yet to acquire) and then one balanced output from the BHA-1 to the balanced input of my BP-26, leaving the other balanced output of the BHA-1 for my earphones?
-
Don't know if this would work, but how about using the balanced pre-outs on the back of the BHA-1 into your balanced inputs on the BP26 Pre. Pre into pre, I know... but that's about all I could think of.

I thought that that is what I had said. :D
I would have the problem of two volume controls but I would hope that the volume control of the BHA-1 could be "fixed" (other than when using headphones) and the volume of the system controlled through the B26 which has a remote.

Not the desired solution, just because of this double volume control. Not to mention the unmuted out of the balanced outs on the back of the BHA,with a HP plugged in.
The real solution would have been a balanced passtrough of the incoming signal on the BHA or a second balanced out on the BDA. This forum asked James many a time for those options, but James stated it wasn't going to happen unfortunately....
James, you are not reconsidering please? Would really make the world!

Hi Guys,
I was just wondering if anyone else has tried the Audeze LCD-3's on the BHA-1, WOW what a combination, especially as a fully balanced rig :)
I have always wanted to spend some time listening to the LCD-3’s after being won over our LCD-2’s and after borrowing a pair of LCD-3’s from Audeze for a customer to listen to in the week I think it is fair to say that I have now been ruined and there was just no way I could send them back. I had always read that the gap between the LCD-2’s and LCD-3’s was quite small with a little more top end detail on the 3's, generally it was said that they were about 10% better for twice the price, well I have to say that is absolute rubbish, with the LCD-3’s you do get more detail but what really struck me was how rich, full and organic the sound was, extremely lifelike. I spoke to Audeze and apparently early LCD-3’s weren't quite at the level they are now as they are now using a thinner membrane making the difference between the 2’s and 3’s far wider.
This isn't to take anything away from the LCD-2’s, they are still one of my favourite headphones, but the LCD-3’s are very special indeed, in my opinion tonality they rival speakers that cost £10,000+ and for what you loose in scale with a speaker you more than make up for with detail and intimacy.
At the moment I'm using a Naim streamer digitally feeding the BDA-1 which is hooked up via balanced to the BHA-1 and then the LCD-3's are balanced into the BHA-1, it really seems that the clarity of the BHA-1 really helps to let the LCD-3's shine as it just helps with top end detail but give fantastic drive, I've been using my Grado PS1000's mostly on the BHA-1, but I think that the LCD-3's have stolen their crown, well worth a demo I would say.
To be honest, if funds allow I would recommend a pair of LCD-3's and a pair of HD800's as both sound amazing on the BHA-1 but both do things very differently and suit different kinds of music, not a cheap option I know, but compared to high end hifi separates it really is a drop in the ocean to get the ultimate headphone set up, as ever I can't resist a photo or two :)

Vipers, totally, totally agreed.
Lazy to rehash everything I've shared on another audio forum out there, I completely agree with your sentiments.
It was one of the toughest decisions for me when choosing between the LCD3 and HD800 as I knew whichever way I'd go that I'd miss the other. As I type this, I'm listening to my girlfriend's HD800 on this rig via the stock 1/4" output and even then it sounds amazing. I can't imagine what it's like via the balanced XLR outputs instead.
I think it's only a matter of time before I get myself a pair of HD800's because this Bryston gear really, really begs for both these headphones pending preference/mood/genre!

I guess this is one of the main beauties of a good headphone rig, you can have a selection of high end headphones that all offer different presentations depending on what you are listening to, whereas with speakers that would be a little more difficult.
I have been told by Sennheiser rep that I should at long last get their much anticipated HDVD 800 headphone amp this week, which will be fascinating to put up against the BHA-1.

I just recently got my BHA-1, and I'm very impressed. It does a great job of powering my HE-500's.
I have to questions that I can't seem to find answers for:
1) the gain switch on my unit is a 3 position switch, but the gain is only labeled "high" and "low". I don't hear any difference between "low" and the middle position. On the "high" position though, the volume goes up (as expected). What am I missing, if anything?
2) my unit has the standard green power LED, but I just discovered Bryston now has blue LEDs (which will be on my BDA-2 and BDP-2). I'd LOVE to have all matching components. Is it possible to send my BHA-1 into Bryston and have the LED changed to blue, and what would it cost? I know that's a huge vanity issue, but I'd really love for all the equipment to match LED colors. It's like wanting to have all your Bryston gear in black OR silver, but not mixed (for me, no offense to those of you who want to mix & match) :)

On my BHA-1 the gain switch is a two position switch. Are you sure you have a middle position on that switch?

AUDIO BEAT REVIEW

I am using BHa with low impedance headphones, Shure 1440 which are 37 ohms
I like transparency of the combination except the bass which is rather shy.
I have to say that iPhone 4S is able to handle them better. Reviewing specs I noticed that iPhones out impedance is below 1ohm.
Will modding my headphones with balanced connectivity improve the low end? Or should just look for headphones with higher Z?
-
I’m considering a BDA-2 / BHA-1 combination to sit beside my HD-800 headphones. My set-up, however, also includes a turntable with a balanced phono-amp. The hope was to have a fully balanced, end-to-end, system but the BHA-1 just has a single pair of balanced inputs. I’m not keen on an external switch box (space, cables) and swapping out inputs to the single balanced input is a hassle. Is it correct that the balanced input to BHA-1 is the best option? (Or, put another way, is there a difference is going from BDA-2 to BHA-1 via RCA and XLR?) And is there a recommended work-around or a long-term solution on the horizon?
Zydeco

I'm speaking out of turn, because I haven't connected with XLR yet. I can say that my BDA-1 and BHA-1 sounded great together via RCA. I *did* use XLR on my headphones, which certainly increased the available volume. I would argue it also cleared up the music. With a nice set of RCA analog cables, I would argue you can make the system work just fine for your purposes.

I've done some experimenting with this. I've compared balanced Cardas Quadlink cables vs single-ended Cardas Clear Light cables from the BDA-2 to the headphone amp. In order to match the difference in loudness between balanced and single-ended, I switched the gain on the BHA-1 back and forth depending on the cable. Frankly, I preferred the single-ended Clear Light cables whether using balanced or single-ended output to my Sennheiser HD-650's. It wasn't an apples to apples comparison because the Clear Light cables cost more than twice what the Quadlink cables cost.
In another comparison, I listened to the BHA-1 driven by the balanced Quadlink cables vs. the headphone output from my BP-17 driven by the Clear Light cables. Listening to a wide variety of music from a BDP-2, I couldn't make a clear decision about the results because of the big difference in gain but I'd say that I was leaning towards the BP-17.
So what have I proven? Probably not much because I haven't done an apples to apples comparison. I do believe that the quality of the cables is more important than balanced vs. single-ended.
I should add that with short cables (.5 meters in my case), I don't think there is any advantage to balanced cables.

After discovering a cabling error in my system I now agree completely with Marius. Even using balanced Cardas Quadlink vs single ended Cardas Clear Light to my BHA-1, the balanced connection is clearly better. If I hadn't gone to a BP-17 preamp which has no balanced inputs, I would also be frustrated by the lack of multiple balanced outputs on the BDA-2.
-
Is it Ok to connect one balanced pair and one unbalanced pair of headphones at the same time to the BHA-1? Manual says that connecting more than one unbalanced pair while using the balanced outputs will damage the BHA-1. But in my case, one pair is balanced, and one pair is unbalanced, and they will be connected accordingly. I don't want to take any chance .

I clearly prefer the HD800's and have listened to all 5 on the BHA. Not only do they sound more like my speakers than the other four they absolutely murder them in the comfort department.

Short version: I like the Audeze LCD-2's (my budget stopped at $1000-ish). I listen mostly to music between Diana Krall and Mumford & Sons (jazz to pop/rock), though i'm finding the nicer my equipment, the more varied my tastes are becoming. Also, take advantage of the balanced headphone input the BHA-1 offers!

Long version: I spent a long time reading, hoping to make the best purchase. I loved this review because it was the same person listening to various headphones, so if I could identify with something we had in common or opposite, i could apply it to all his reviews.
Historically, I'm a long-time Sennheiser fan. They offer the best in comfort and I've loved their sound for over a decade. However, I never owned/listened to anything more expensive than their 500 series (595's were my last), and never with GOOD dedicated amplification. I now work nights AND have a baby on the way, so headphones have become my most frequent method of listening, both to music as well as movies & TV.
Grado RS-1
I started with a new Rega EAR amp (apparently, the new version is better than the original, but I have not basis for comparrison myself) and pair of Grado RS-1's. I found them to be too bright. As I wanted to turn music up, the bright/treble parts literally became somewhat painful due to their volume level. By comparison, i found other parts to be too quiet, especially the bass.
Sennheiser HD700
As a longterm fan of Sennheiser, I figured this was my golden spot. Unfortunately, I felt they also were too "bright", the treble being almost painful at louder levels, though the Sennheiser's were better overall than the Grado's, especailly having better bass.
Sennheiser HD650
I figured the old "gold standard" HD650's would do it, and they did. They had the Sennheiser sound I loved and were well balanced tonally for me, though I did find them a tad "dark"?
HiFiMan HE-500
At the same time I had the HD650's, I had HiFiMan's HE-500, my first planar magnetic headphones. The detail absolutely made short work of the Sennheiser HD650, though I had a real problem getting use to the lack of comfort compared to Sennheiser.
At this point, I got my hands on (and then purchased) a Bryston BHA-1. Such an amazing difference! The Bryston amp is far cleaner, and made me realize the Rega EAR sounded darker and had less detail.
I also noticed something interesting with the HE-500's: as I was listening to Michael Jackson's "Thriller", some of the sounds/effects in the music sounded odd. They had always been in the music, but now they stood out so much that they sounded "apart" from the music. They were absolutely NOT blended in. That made me concentrate more on those sounds, and it completely ruined the "toe-tapping" effect of listening to music in the first place. As i started to listen to other music, I noticed the same thing.
I wholeheartedly believe this is a byproduct of modern day sound studio mixing, and that it would not be present in any live recording or well-recorded music. While the HE-500's are detailed (and to me, "bright"), I didn't not notice this synthetic quality in anything from Diana Krall, Dean Martin, Frank Sinatra, etc.
Audeze LCD-2
The brightness turned me off though, and I read lots that the Audeze LCD-2's also had a "dark" sound. I got my hands on a pair and fell in love! They are darker without losing detail. Kinda impressive really. That being said, I really believe what the person who reviewed all the headphones in the link I included said over and over: which headphone you like will change depending on what music you are listening to. For me, the Audeze's are it.
Bryston BHA-1
You really should switch to a balanced headphone cable. Regular stereo plugs share the negative terminal of the left and right headphone. I don't know if that is what causes the difference, but the balanced input has more volume range and (to me) better sound stage and musicality.
I had an unfortunate instance where the tip of the stereo headphone jack broke off on two different (brand new) HiFiMan cables. HiFi Man sent me the second set free when the first broke. I had to open the Rega EAR and remove the tip. Ugh. Anyway, after the second set broke, I figured I'd just go to Radio Shack and buy a connector and solder it on. It was a Friday, and I didn't want to miss using my headphones all weekend.
Bryston is kind enough to include the wiring diagram for the balanced inputs in the owner's manual. So I figured why not try that too? I made one pair with a stereo plug and one with balanced plugs. I did some google-ing about soldering and bought some cheap wire and plugs to do a practice run on. I picked up Neutrik connectors at a nearby store and by Friday evening, I was A/B testing the two cables, the only difference being the connectors.
So, soldering the balanced connectors isn't very difficult, should you be so inclined. If you're not though, i highly recommend getting it done. It'll be worth the time and money to get the most out of your BHA-1.

Hi Jim,
So far I like the LCD 2's best (still have the 3's as well) then the Grados and then the Senn's and then the HE500 in my setup.
james
Same order as James, except I prefer the 3 to the 2, and sold the other three and kept both Audezes
-
The music you like makes a lot of difference.
For classical music IMOnothing touches the Senn Hd800!
Cheers,
Bob

I clearly prefer the HD800's and have listened to all 5 on the BHA. Not only do they sound more like my speakers than the other four they absolutely murder them in the comfort department.
The Sennheiser HD800 sound the most accurate and honest. Most audiophiles do not want this from all my observations as they prefer colourations. To each their own I guess. :scratch:
You will appreciate the upgrade to the Cardas Clear cable with the HD800's. I also went Clear on balanced xlr cable between source and headamp as well. Enjoy the great sound. :thumb:

I also upgraded the balanced cables to the headamp from Cardas Quadlink to Clear Light. I was able to a/b the cables before ordering the Clear Light. Maybe I should reconsider Cardas Clear in this application.

The reason I went with the Clear was I wanted to preserve as much of the sound quality of the signal from the BCD and BHA. Clear cables did this and is certainly more expensive but I found it worth the expense. The better the recording, the better the Bryston/Clear sounds.

It will certainly be interesting how the balanced Sennheiser cable sounds on the HD800's when launched next month, as I've yet to hear the HD800's balanced yet but many people have told me to hear them at their best they need to be balanced, that is definitely the case with the LCD-3's.
I have a had a couple of customers now that have bought both the HD800's and LCD-3's as they are both totally different but equally as good at different presentations, that is the real beauty of headphones, you can have more than one pair, which you wouldn't normally do with speakers, and it may seem a bit elaborate but for the combined price you would struggle to get a decent pair of speakers for that cost, in high end audio terms quality headphones are a bit of a bargain in my opinion.
Now I have the HDVD 800 on demo, it is really interesting as it definitely gives the HD800's an even more detailed presentation but also helps fill out the sound a little, saying that the BHA-1 is still my favoured head amp, and so far all the customers have agreed, it really shouldn't be underestimated just how good the BHA-1 is, many customers have bought their amps in to try and so far the BHA-1 has seen them all off :)
The BHA-1 really is quite special when it come to headphone amps.

Hi!
been enjoying 2 complete live Wagner Rings these last weeks (Proms, Bayreuth) with my BHA1/HD800. Total bliss and no fatigue on the head or ears whatsoever. Many, many ours of constant listening. Great combination they make. (only complaint is the lack of remote control, but thats beside this topic...)
The issue at hand is that my fellow housemates didn't enjoy it as much as I did.... And now I am on the lookout for a closed Headphone, with the same specifications: great comfort, great sound, overear, and , of course: no external radiation. What would be your best bet? Please let me know.
And while your at it: Im looking for a set of in-ears too. Been commuting quite a bit lately, and will for the time coming, so need a great pair of eardbuds, that filter out all train noise.... seen the Sennheisers http://nl-nl.sennheiser.com/in-ear-headphones-earphones-ie-800-ceramic (almost as expensive as the HD800's) but Grado offers some too http://www.gradolabs.com/page_headphones.php?item=6678c09cae1e8f02045b1733923ed4b6, amongst others. Some guidance would be appreciated. Don;t want to have a pair of B&W p5's or the likes, I feel even more awkward looking than without already...
Thanks,
Marius

HI ,
on the search for closed or sealed headphones the choice so far is between Ultrasone http://www.ultrasone.com/index.php/en/products/edition-8.html and Audio Technica http://www.audio-technica.com/cms/headphones/5215eb84d110cad5/
James, have you listened to these 2 phones on the BHA1? Any thoughts?
Thanks,

Greetings from NZ! I have just received my new silver BHA-1 after trialling that and the HDVD800 with my HD800s. I got all brave and reterminated the standard cable with a 4-pin XLR (which I did for the trial).
Quick question, perhaps one that James and/or the modders can answer. I see a couple of 4,700uF polarised caps bang in the signal path. Now, most amps where I have seen such beasts in such places, I have either replaced them with bipolars and bypass caps, or removed them altogether. I have experienced great results in replacing the Jamicon caps in my MF DM25 DAC with Elna Silmics.
Now, putting warranty issues aside as I figure that my 20 year warranty would be void if I got anywhere near it with a soldering iron - are these really necessary? Has anyone modded them and what was the result. I figure that if my DAC has input caps, then why have these, although they would help make this bulletproof.
Apologies if I have started a war...
-
I'm a little disappointed in the demand and resale value of the BHA-1. I've been trying to sell mine for over 4 months for as much as $350 off new ($1295) and in basically mint condition and I have literally zero interest.
Is this typical of Bryston products? If so you won't see me buying Bryston again. This is pretty frustrating.

Try AudiogoN. They only charge $4 to list it and 2% of the sale price. You may get more action there than where you have it. I've had good luck with them.
Do you have the box for the amp as well as a receipt from a Bryston dealer to validate the warranty?
Bud
-
Yes to both. I'm not a fan of audiogon, but I might have to resort to it. I thought I would keep it to headphone and bryston favored boards thinking it would sell quickly.
-
I think you'll have better luck on Audiogon. I don't think it's a question of Bryston's quality or resale value as much as it is of not reaching enough potential buyers.

I think the suggestion you are making that Bryston products don't have a good resale value based on the experience you have described is off base. First off you can find a Bryston dealer that will sell you a brand new factory sealed unit for a little over $1K. No matter how new or pristine your unit is used product buyers are always looking for a deal that at minimum would be 25% under what they could by it for new so in your case you're now down to $750.00 Secondly, headphone amps are not a large market compared to other Bryston products. Try this with a BDP-1 or a 4B SST2 and see what response you get. This product is very highly reviewed, is of typical bullet proof Bryston quality and from what I can tell is selling well. I think your problem is you are asking too much for it.
-
I didn't know you could get a new one for $1000, how are people getting $400 off? I bought the first BHA-1 sold so it was $1295. You said 25% should be deducted and $350 off $1295 is 27%. I am in line with your suggestion, except it seems I'm being gutted by gray market dealers. This is where the blame falls on Bryston for allowing the value to fall so much. Denon had the same problem with their D5000/7000 headphones where they first sold for nearly twice what gray market dealers eventually sold them for and their value was forever lowered because Denon never protected their product until it was far too late.

I'm just trying to help you out by encouraging you to be realistic. First, I didn't say "people" were getting $400.00 off on the price of the BHA-1. I said you can buy one at $1K+if you shop around. It's been my experience that some dealers sell at list price and others up to 15or 16% off list. For example, if you don't have a dealer in the area and all the dealer is doing is ordering the product from the factory shipped directly to you they will sometimes acknowledge that "no value add" transaction by selling at less than list price. Another example are systems integrators who make most of their money from design and labor will sometimes offer a "cash and carry price" that is less than list. Where I got the $1K+ estimate was assuming a 15% reduction from the $1,295.00 list price you cited. 15% of $1,295 is less than $200.00.
As for Bryston's role in devaluing the resale price of the BHA-1 or any other of their products, nothing could be further from the truth. They have no control what happens to their products after they are shipped to authorized dealers. A lot of these gray market outlets will pick up the stock from dealers when they go out of business or for some other reason. Bryston goes out of its way to warn buyers to stay away from the gray marketers. They even list their names on the web site.
The primary reason I'm responding to you is not to get in a pissing contest as to why you find yourself in this situation but to dispel the hostile attitude you are showing towards Bryston by blaming them for your predicament. As an owner of several of their products I have found them to have the highest level of integrity in their products, business dealings and above all customer service and focus.
-
I think you would have a hostile attitude if you were told 57% ($750) was the best you could get from selling a product in perfect condition with the build quality and warranty Bryston offers.
By the way, $1295 was only for the first 100 or so units before they changed the BHA-1 and it went up to $1395. They added a pair of XLR outputs so it would integrate better into a larger system. So yes, I saved $100 buying it early, but now I can't sell it because it doesn't have that feature. Compound that with what you are suggesting for a reasonable selling price, and I may not even get 50% out of this. You better believe I'm hostile.
-
Why would you sell it. You'd have to pry it out of my cold, dead hands. :scratch:

Upgrading to Headamp GS-X II
-
Don't know about the rest of the GS-X HeadAmp, but wished Bryston would have thought about those locked XLR at the back (Bryston says are not possible), and.......the loop connections.
Now that would have solved a great deal of inconsistency in their own lineup :duh: and prevented switching cables all the time, or, as in my case, have the BDA1 use its rca connection to the bp26, to favor the BHa1 with the balanced ones.
If only.
Cheers. :|

So, I take it that no one has considered removing or bypassing these electrolytic caps? James?
I have left it powered up for the last week and are thoroughly enjoying it. The distributor will have a demo BDA-2 in the next few weeks, look forward to seeing how that performs.

They are there for safty reasons to prevent any chance of DC from being passed on.

BHA-1 Mods?
According to Byston's schematic, there are no input coupling caps but there are four 4700uF NP output coupling caps 3C15, 4C15, 5C15 and 6C15. If the DC offset voltage at the output of the power op-amps is small, it would be interesting to see what, if any, sonic benefits might be realized by shorting out these coupling caps. If the DC offset is not small, audio quality polypropylene and polystyrene bypass caps could be tried. Or DC servos employed.
Also, it has been alleged that the sound of Bryston power amps can be significantly improved by replacing the current source resistors of the input diff amp pairs with current regulator diodes. In the BHA-1, there are a number of 34.8K current source resistors 3R2, 3R4, 4R2, 4R4, 5R2, 5R4 and 6R2, 6R4 which, given +/- 20V rails, result in 0.56mA to each diff amp pair. Each of these resistors could be replaced with a 1N5291 current regulator diode having a dynamic impedance of 1.9MegOhm, a more than 50 times improvement.
If any brave soul (or Bryston Engineeing) tries these mods, please let the rest of us know how they work!

Try CAM. Lots of selling on this site. Your price is good and you should fetch $900 for your BHA1. If it had the extra XLR outputs to double as a preamp you could get 1k easily as I did.

MEMO: To All Bryston Customers
SUBJECT: German Review of Bryston BHA-1 Headphone Amp
STEREOPLAY
Full Steam Ahead!
High performance amplifiers have always been a domain of Bryston. With the BHA-1 the Canadian HiFi specialist now turns to the owners of especially high quality head phones
It is surely not presumptive to assert that the majority of headphone jacks in HiFi components represent compromise solutions. Most of the time the budget is tight and invested in other more sales oriented items, which is why it rarely suffices for truly high quality headphone electronics. Although with standard solutions, for instance with the popular OP-amplifier chips JRC 4556 from New Japan Radio, quite good results can be attained, there is no doubt that with a separate headphone amp upmarket listeners play in a different league.
Until now only very few specialists devoted themselves to the area of pure headphone amps. With the worldwide boom, especially with very high quality headphones, this area is now also interesting for larger manufacturers whose primary core competence is building amplifiers. The best example for this is Bryston. With the BHA-1 (for 1,600 Euro) the Canadian manufacturer now introduces his first full-blown headphone amp. Stop, that's not quite accurate, since the BHA-1 thanks to its adjustable line outputs can also be used as a line level preamp. The BHA-1 provides three analog inputs selectable via a toggle switch on the substantial aluminum front panel which accept all types of program sources from smart phones to sound studio mixing consoles. There is an electronically balanced XLR input, an unbalanced RCA input with RCA jacks as well as a likewise unbalanced input with a 3.5 mm. stereo minijack for mobile equipment.
The Name is the Program:
The abbreviation "BHA-1" stands for "Balanced Headphone Amplifier." Similarly like a bridged power amplifier which drives loudspeakers, the BHA-1 can handle both headphones of the listener completely ungrounded by means of two opposite phase amplifier sections. (refer to the section Headphone Bridged Amplifiers..." on Page 45) A prerequisite for this is that both transducers in the headphones can be controlled in balanced mode without the necessity of a ground. Also "normal" headphones can be connected to the BHA-1 with the usual three pole phono plug; in this case, however, only the non-inverting output stage delivers the music signal.
During the listening test the Bryston BHA-1 showed itself to be absolutely neutral, despite that a multifaceted show-off with raven-black bass. Thanks to its gigantic power there should never be a loudness or lack of dynamics problem even with the ultra softest headphones. The headphone transducers would "melt" before the BHA-1 causes distortion.
The comparison between unbalanced and balanced operation was very interesting with the HD 800 which Stereoplay could elegantly carry out thanks to its specially made balanced CH 800S connection cable. In unbalanced mode the German-Canadian duo played more in the center and altogether a bit more organic, and in balanced mode - thoroughly in a positive sense - somewhat "snappy" and even more emphatic in the bass region, and additionally it seemed spatially somewhat wider. With balanced operation the impression arose that the overall reproduction succeeded one tick "faster" and more explosive.
According to personal taste one can give preference to both connection modes. However with objective observation one must concede balanced operation small advantages with a somewhat more businesslike interpretation, while the unbalanced mode in musical regard showed somewhat more boundedness. The best part is that
with the Bryston BHA-1 both variations can be realized. Also as a line preamp the Canadian cut a good figure soundwise, the only small weakness was a very high voltage gain (amplification) so that one could really never get beyond the 10 o'clock position with the volume control.
Jürgen Schröder
Stereoplay Test Rating:
• Measurement Values 9
• Practical application 8
• Value 10
• Sound - Absolute Top Class
Elaborate circuit technology and bridged configuration help the BHA-1 amplifier achieve forceful-clear, compression free sound with exemplary clean bass. Can supply exorbitant volume intensity - not only in balanced mode.
CAPTIONS:
With an optional Rack Mounting Kit the BHA-1 Headphone Amplifier, thanks to its 19 inch compatible measurements, can also be mounted in sound studio peripheral racks without any problems. The backside arranged connections for the line inputs and preamp outputs also simplify the cabling. The enormously robust steel cabinet deserves the rating "unconditionally road-worthy."
The circuitry of the BHA-1 Headphone Amplifier consists primarily of six discretely built-up (with individual transistors) operational amplifiers, of which two serve as input amplifiers (above), and the other four in channel connected pairs as bridged amplifiers (below). The analog operating loudness potentiometer from Noble (little blue box) follows in the signal path after the balanced input stage.
Besides the standard wired four pole XLR-4 jack the BHA-1 Headphone Amplifier also offers the connection alternative of two channel separate three pole XLR-3 jacks for headphones that can be operated in balanced mode. The driving amplifier stages are however the same.
Balanced Headphone Connection:
Headphones which are suitable for balanced connection to appropriately operating head-phone amplifiers are recognizable inasmuch as then both transducers, comparable to phono cartridges, require one plus and one minus connection as separate channels. Accordingly a balanced headphone cable must have four inner conductors, which likewise may have no connection to each other.
High quality headphones often already incorporate quadripolar connection cables, where-in the minus connection of both channels is often connected to the ground contact (rear, broad area of barrel) of a conventional phono plug. If one wants to rebuild such a cable for balanced usage, it is recommended that a four pole XLR plug be soldered according to the following schematic diagram:
Bridged Headphone Amplifiers - Why?:
Fully bridged- or Bridge-Terminated-Load-Amplifiers (abbreviated: BTL) consist of two amplifiers per channel, one of which outputs a normal, the other a 180 degree turned (inverted) input signal. Although bridged amplifiers - no matter whether for headphones or loudspeakers - are not principally superior to conventional amplifiers they do offer so to speak inherently two constructive plus points: By means of the opposite phase method of operation, from the inverting and non-inverting bridge branch, they can supply very high output levels even with relatively low supply voltages, which in turn produce high, undistorted maximum volume levels even when connected to difficult to operate, high resistance headphones with impedances over 300 ohms. A further advantage of bridged amplifiers is that the load (headphones, loudspeakers) remains balanced and not grounded, i.e. it floats between the inverting and non-inverting amplifier output. Consequently with bridged amplifiers the electrical floating ground as a point of reference is irrelevant since the load is now transferred back and forth between the modulated positive and negative supply voltages. Attributable to its floating output signal, bridged amplifiers are inherently less susceptible to load dependent crosstalk, which can easily occur with single ended amplifiers. The reason for this is as follows: If the load current flows over the floating ground on the way back to the power supply, then because of a not infinitesimal conductor resistance a voltage drop occurs, which modulates the reference point of the entire circuitry dependent on the size of the signal. If the left and the right channel split the floating ground which is especially the case with headphone amplifiers because of their three pole phono jacks, then channel crosstalk can occur. Therefore well thought out and in addition low resistance ground routing is the first commandment for normal headphone amplifiers. However the ground free operation of bridged headphone amplifiers requires that the headphones being used are connected with a four conductor cable to the output.

The BHA-1 is bedding in nicely. There is not a lot of Bryston here in NZ, but I have the BDA-2 to keep it company. Sounding very good so far. I upgraded to Valhalla from Tyr before upgrading the DAC.
It does not quite sound as organic as my last DAC, but that may just me getting used to the more forward nature. Certainly all smiles so far :D
I re-terminated the standard HD-800, awaiting an upgrade in the mail.

Hi Guys,
Considering how fantastic the Audeze LCD-2's and LCD-2's sound with the BHA-1 it is really exciting news that Audeze are just about to extend their range of high end headphones with 2 more models, the LCD-X and LCD-X.
The LCD-XC being quite an interesting addition as it is the brands first closed back design, making it the first Planar Magnetic Headphone that is closed back, that I am aware of anyway.
Both the LCD-X and LCD-XC feature new driver designs called Fazor Technology which uses a thinner and lighter membrane which should produce a faster and more insightful presentation, they will certainly be fascinating to listen to once released.
They both look extremely stylish I have to say, with the LCD-X finished in anodized aluminium in gun-metal gray in black lambskin and the LCD-XC finished in black lambskin, gun metal gray aluminium enclosure with a choice of 4 wood cups, Iroki, Walnut, Purple Hear, Bubinga, please see pic below.
Looking on Audeze's website the new models are due over the next month with prices nearer the the LCD-3's, so not cheap, but I bet they are going to work a treat with the BHA-1, got mine on order so will update once they are with me :)

Hi Paul,
Great news!
Just what I am looking for these last few months. A closed audiophile, balanced headphone. My family would love me for that. I would be able to use the omnipotent BHA1 so much more. I tend to get these aggressive looks now and then using the HD800.....
Let us know how they sound, and, feel. I've still to encounter a set of headphones with the same comfort as the HD800. Other than the good old Jecklin Floats, which are out of production unfortunately. they sounded like no other..
Cheers,
Marius

Well, my first post on this forum - although I've been reading this thread for a while.
A few weeks ago I bought BHA-1 and paired it with HD-800. Sound was so nice (although not yet perfect - working on cables), that I jumped head forward and bought second-hand BCD-1. I am sold to Bryston sound, and will be more when I switch cabling from RCA to balanced on both ends of BHA-1.
Just two things bother me - after reading how powerful BHA-1 is, I am finding myself listening with volume at 4-5 o'clock (un-balanced connections and with low gain setting). Am I deaf (might be the case ;) ), or is there something wrong with my BHA-1, or maybe that's how it is?
I know that high gain would help, but... unfortunately I can hear the SQ difference between high and low gain settings.
BTW Brystons are great sounding equipment, I wish I had suitable room to use pre+power amps+ some decent (ATC?) speakers.
-
You might consider wiring your headphones to use the XLR/balanced connector (if they are not already). That'll gain you some loudness.
I'm running Audeze LCD-2's and I've never (on low gain) had to go past about 1-2 o'clock on the dial, and that's for older recordings.
-
Thanks Grit. I am planning to go balanced both ends - tested a few XLR ICs between CDP-1 and BHA-1. Enjoyed only one of them - Organic Audio (copper). Unfortunately none of the balanced cables for HD800 are easily available so I'll most probably purchase something from abroad without testing.
On the note side - since the CDP-1 arrived without power cord, I borrowed a few from friendly shop and had a chance to play/compare.
While I could hear very slight difference between them when connecting CDP-1, but the difference was quite obvious when changing power cords on BHA-1. Very surprising to 'power cord difference' non-believer which I used to be. ;)
(Sorry for potentially opening can of worms with above statement) ;)
-
The new LCD-X should be more neutral than either LCD-2 or -3 and that is something I could use. The reason I stayed away from Audez'e headphones is their rather dry nature which makes them unsuitable for classical. I think HD800 are still top notch but with more driven genres except progressive ones, I think Audez'e might be more suitable. The hassle is, they don't come cheap and they are nowhere to be had in Croatia and paying more a grand Euro for something I never listened to seems pretty silly.
-
It would be really cool if Pass Labs decided to make a headphone amplifier. Owning both the Bryston and Pass would be a dream come true.

I purchased a more expensive XLR for my Audeze. However, I also got greedy and just made my own. If you don't mind cutting the 1/4" phono plug, confirming continuity with a meter, and doing some very light soldering, you can alter your own cable for just a few dollars. While it won't change the physics of the cable, it will give you a balanced input. Bryston was kind enough to include the pin-out assignments in the BHA-1 documentation, so it was pretty easy.

I loved my Sennheiser's more than anything. Ever. Most comfortable headphones I've ever worn. I tried to replace them with the HD700's, and I just didn't love the sound. It was very revealing, but that wasn't as nice as you'd hope. I imagine for classical music (where I read they shine), that'd be be great. For everything else I listen to though, it drew my attention to each instrument, too much. As a result, I never enjoyed the music. I had a similar experience with HiFi-Man HE-500's. The Audeze LCD-2's finally got me what I really hoped for. My final test: I was "dancing" in my chair when using the Audeze's, just because I was enjoying the music.
I only offer up my opinion because, however you relate it to your own preferences, it may help make your choice easier.
-
I am finding myself listening with volume at 4-5 o'clock (un-balanced connections and with low gain setting). Am I deaf (might be the case ;) ), or is there something wrong with my BHA-1, or maybe that's how it is?
I also use a HD800 (balanced terminated with 2 x 3-pin XLR) with the BHA-1. FWIW, with 'low gain' setting, my volume dial is usually between 8 and 9 o'clock. I listen to mainly classical music (a mix of chamber and large-scale orchestral works) and some jazz. Even with the notoriously difficult-to-drive HE-6, on 'high gain' setting, the volume dial seldom goes beyond 10 o'clock. 4-5 o'clock will be deafeningly loud, I'd imagine. Or perhaps you just prefer your music LOUD! :P
-
LCD 2.2 were on my short list as well, in fact they were #1, but there is no Audeze dealer/rep in Poland - so it would be a "blind date" buying them.
I borrowed HD800 and T-1 from local shop for a weekend , and out of the two I preferred HD800 much better.
I have some complaints from my "better half" as HD800 are very "open" - so when I listen to music she is forced to listen to it wanting or not.
With BCD/BHA/HD800 combination music gets very engaging, not perfect match for laid back listening. I do enjoy this "surgery of the sound" (for now), but it is more like being in the middle of filharmonic orchestra than sitting in back rows.
I shall wait for closed type Audezes and money permitting purchase LCD-XC - while it is hard to place ATC and Sonus Faber speakers in one room and keep reconnecting them to match music and listeners mood, it is very easy to enjoy the best of both words with headphones.
My manual skills are 1/10, but may try to have the connector replaced with XLR.
I do like the music loud - with HD800, they sound dull/grey when not fed with wats.
-
If you take a crack at the XLR connector, buy two or three Neutrik connectors so you have 1 or 2 to test on, and buy some cheap wire. This way, you can test the process out BEFORE you cut your headphone cable and try to solder them. I botched my first one, but with 4 connectors on each XLR, I had 4 chances to learn. By the time I did my actual headphones (2nd connector), my soldering was almost beautiful. Just don't let your first attempt be on your headphones cables. :)
-
Safety First! - I'll have it done by somebody else, it will save me buying next cable ;)

Thinking of finally changing my current head-fi set-up, B60R and 2BLP pro, next month with the BHA-1 as a birthday gift to myself.
(http://www.audiocircle.com/image.php?id=88753)
Funny I asked James about the possibility of making a headphone amp almost 10 years ago, http://www.audiocircle.com/index.php?topic=13425 ,but it hasn’t really been a priority for a while, but now that my son is a teen I’m back to phones but for different reasons.
Anyway curious if anyone has any insight on the AKG K701s paired with the BHA-1 (especially when listening to vinyl) as I’m currently using the 2BLP pro’s headphone output which offers more than enough power for most inefficient phones , the B60R is fine for the Grados and passable with the Senns but runs out of steam with the 701/501s, I’m hoping the BHA-1 will replace both.
As I use headphones when required at night for music (CD and Vinyl) and movies, I’ll loose the ability to switch between sources but I’ll just reconfigure the pre at the front of the room to handle that.

Well, just pulled the trigger on a used BHA-1, should be here within the week or least for my birthday on the 18th. I'll keep everyone posted, curious how it will stack up to my current combo, just might be time to mod the the K701 cable for balanced configuration. :D
-
Happy Birthday rob80b!
I am sure you'll enjoy BHA-1, and 99% sure you'll enjoy it even more when going fully balanced (IC and headphone cable).
I tried few ICs - balanced makes a big difference, can not wait to get back home and order balanced cable for HD800.
Next step - power cord. I do not want to open can of worms, but even such a sceptical person as I am could hear the difference between power cords connected to BHA-1.
-
Yes ,one for the power cord team, :thumb:
-
Here is another one for the balanced solution!
Have just connected the new balanced senn cable to my hd800 (to the BHA-1, but you probabely guessed that). Would have to be completely deaf not to hear the difference. The 3d like rendition of the music is incredable. Have my BDA conected via balanced XLR cables (Siltech) to the BHA, but have never tried other cables, so do not know the synergy here. Have completed several extended listning sessions at times switching cables and my single ended cables are now for sale.
Cheers,
Bob

Hi Bob,
Know the feeling, amazing isn't it? Wonderful
Combination indeed.
Are these Sennheiser originals ? I've made my own balanced cables out if the accompanying standard cable. Would be interested whether an original Senn balanced cable would be any better?
Have a link for that ?
Cheers!
Marius
Ps reconnecting the BDA to the BP26 through the balanced connection gives the same experience. That's why we're hoping for a balanced pass through someday...

Only managed to squeeze in a short listen, very analogue sounding off the BCD-1 and the K701’s displayed a much better organized sound field, the imaging was more naturally spread left to right as opposed to being either left or right with a distant centre image, nice.
Timbre was spot on from what I can hear, cymbals having a natural shimmer, bass I will need to do more listening.
One large caveat though which other have pointed out is the volume control, with the single ended out high gain, having very little change between 10 and 4 o’clock and only kicks in at the 5 o’clock to max location with the K701s with louder CDs, with the Grado SR325i’s I had problems getting a proper balance between almost loud enough to too loud with quieter CDs, vinyl will obviously be problematic.
Currently I’m running 30ft shielded RCAs from the front to my listening position at the back, so I may run the BCD-1 balanced and the rest single ended from the Pre-amp.
If I’m so inclined I may rewire the K701s this weekend with the 4 pin balanced connection, hopefully that will help with most of the listening.
Anyway I leave more impressions once I have time.

Well a few interesting hours doing some comparisons between the stand alone BHA-1 and the BHA-1 as a pre for the Bryston 2BLP pro.
Music Selection:
Fluke “Puppy”, Kathleen Battle “Grace”, Massive Attack “Mezzanine”, Underworld Dark and Long” and Stravinsky “Petruska” (conducted by Stravinsky 1960).
Source: Bryston BCD-1 from tape-outs on my pre with a 25’ run of BlueJeans RCA LC-1 Low Capacitance Audio Cables to the BHA-1 behind the couch.
Headphones. (all single ended) AKG K701, AKG K501, Grado SR325i and Sennheiser HD580s (with 600 grills and HD650 cable).
First up using the AKG K701s both setups were delicate, Kathleen Battle’s voice soared upward with a natural clarity without reserve. Stravinsky’s symphony was well laid out with discernable imaging with front to back layering, midrange being well defined and the crescendos had weight and impact with excellent tightness and definition.
The techno selections also fared very well and a joy to listen to. :)
The Grado SR325i’s also performed similarly, but what’s interesting is that do to the odd volume control they were close to the K701s on the dial, normally there is a much bigger spread. Now it’s known both the Grados (32 ohms) and AKGs (62 ohms) like current and that may be the deciding factor which allowed them both to perform at their best, which speaks a lot for the BHA-1 in supplying necessary current.
The Sennheiser HD580/600 at 300 ohms did not scale as well, previously on prior setups I found the inefficient K701s (at least as far as bass is concerned) needed more gain but here it was the reverse, even maxed out the BHA-1 could not supply enough volume, they’re probably the most likely candidate for the first balanced cable up grade.
Compared to my previous set-up using the Bryston B60R as a pre for the 2B was also fine, although not as delicate, maybe because I had to use an unbalanced to balanced adapter where as the BHA-1 and 2B are balanced through out.
Overall though once I was able to match unity gain between the BHA-1 and the BHA-1/2BLP pro combo I was hard pressed to discern an obvious differences, if any; the similarity I would have to attribute to the preamp section of the BHA-1.
I’ll need to dig a bit more into the forums to see if balanced headphones resolve the volume issue, because as it stands now it is very difficult with single ended phones (at least it is for the phones I have on hand) to adjust from almost 5 o’clock, which is almost there and then a little incremental nudge makes it too loud with some recordings. :scratch: (solved see next post)
Setting the 2BLP pros dial for unity gain with the BHA-1 produced the same results when monitoring, with the gain on the 2B maxed the volume control on the BHA-1 was more linear much like the B60 and BP25, with most listening between 9 and 1 o’clock on the dial depending on the source.

Update:
Managed to hook the BCD-1 up directly with balanced cables which has resolved the volume control issue with CDs so that the it now functions best between 9 and 1 o'clock, so plenty of gain if needed :thumb:

Hi Marius,
It is an orig senn cable, partnumber CH 800 S. Would assume that putting an XLR ending on the stock cable has a similar effect. Have no personal experience in this. Have a great dealer that tried out the Cardas cable, but this did not provide a clear gain (despite 750 vs 300 euro, oouuch). As we share the love for "say the Harmonia Mundi" portfolio, I agree we are best of with this combination (with the possible exception of the more esoteric offerings from Stax). For the "more contemporary" music: I can not wait to have my Grado's reterminated.
Cheers, Bob
-
Anyone here with a BHA-1 try using an aftermarket power cable?
I'm having issues fitting an Isotek EVO3 Premier cable to the BHA-1 IEC input because of the protruding fuse drawer. Driving me nuts - anyone know of any work arounds / good cables that fit?
-
Hi Bob,
Is this the one: http://www.custom-cable.co.uk/sennheiser-hd800-xlr-connecting-cable.html ?
Seems to be the same cable , only with another, Sennheiser, XLR. If one can believe the photo that is.. That cost you 300E? Boy, a long way from the 125 i paid for an extra standard cable redone with Neutrik XLR.
Marius

Yep,
Seems like the same. Does have Sennheiser on the plug, should be worth the extra cash. Really fIts like glove in the xlr-port of the BHA. As the Grado does not seem to have a detachable cable, I am tempted to follow your Neutronic example. Conviced it will make a huge difference. Single ended the comparison was a matter of taste and sort of music. Now the Grado is blown away completely, even on its home turf.

So far the BHA-1 is living up to all its hype, but in the meantime I’ve managed to managed to wire up the Sennheisers and AKG K701s with 4 pin XLRs and made up a 4 pin XLR to single ended adapter, I appreciate the extra gain especially with the Senns, but through extended listening I’ve yet to hear any discernible difference between single and balanced connections.
The biggest improvement has come about with the use of Canare L-4E6S on the Senns, I noticed a similar result when I re-wired my AKG K501s with the same cable years ago, listening to Leslie Feist’s album “The Reminder”, the result was smooth sailing with plenty of detail all the way, the AKG K701s with the re-wired balanced stock cable was a bit too hot, prior to using the Canare cable on the Senns I preferred the K701s.
Should note that the Canare cable is fairly thick so best left for stationary listening.
(http://www.audiocircle.com/image.php?id=90145)
Overall though the BHA-1 IMHO has really pulled out all the stops and I can really appreciate the different sonic signatures with all my phones, they all sound excellent in their own way.
Another unexpected attribute is running my Bryston 2BLP pro off the BHA-1s XLR outputs, previously I had always used an RCA to balance adapter to accommodate the B60’s pre-out, which I now know is a big “No No”, the 2BLP would previously get fairly hot even with headphones, now it stays cool and as far as I can tell matches the sonic attributes of the BHA-1 headphone outs.
The power hungry AKG K501s run off the headphone jack of the 2BLP pro which offers more than enough power for any headphone is now my “go to” set-up to chill out, which I attribute to the quality of the BHA-1s preamp section.
(http://www.audiocircle.com/image.php?id=90146)
A by and large a win win situation :thumb:, at least for me, from my previous set-up and a much appreciated birthday gift to myself. :green:
-
Just to see is if the above mentioned attributes transfer over to using the BHA-1 as a preamp I managed to hook it up front and put it through its paces.
Basically your purist set-up, BCD-1, BHA-1, 4BSST and the Dynaudio Special 25s.
(http://www.audiocircle.com/image.php?id=90190)
In a nut shell I heard the best reproduction of cymbals that I’ve had the pleasure of hearing, definitely one up on my previous BP25P which was true to its numbers but which I have to confess I felt was getting a little long in tooth and was replaced by the very affordable Emotiva USP-1 this year to accommodate HT bypass with sub woofer management, but only because the EMO IMHO did sound better even with the phono, sad to say. :(
Needless, I was losing faith in my coveted Bryston, but the BHA-1 in its minimalist approach has brought a whole new sound to the playing field, the word that comes to mind is “Crystal Clear”.
My biggest caveat with the BP25P, at least in system, was the lack of distinct layering and depth with the Dynaudio Special 25s, the USP-1 resolved and that and was what made me question the BP25s resolving power.
The BHA-1s imaging prowess IMHO, at least from what I’ve heard so far is second to none; width, layering and depth is very distinct, with no doubling up, the full audio spectrum appears to have better resolve top to bottom.
As I mentioned cymbals took on a new vitality, they were distinctively real when listening to John Surman’s “Stranger Than Fiction”, very silky but not in the bright sort of way, just right, the same being said for the piano and Surmans sax, the drums displaying that tactile feel.
Just to change pace I threw on some Techno, Underworld’s “second toughest in the infants” expecting the clarity of the BHA-1 would have be reaching the volume knob, which was not to be, sat down and listened again through the whole album. The bass was extremely well resolute and again with the resolving power of the BHA-1 the music was a pleasure to listen to.
So once more as with the SST series, the BCD-1 and now the BHA-1 Bryston continues to show what can be done, thanks guys! :thumb:
Too bad there’s no HT pass through, remote and bass management, other wise the BHA-1 would stay right up front, plus the silver doesn’t match the rest of my equipment. :scratch:
Maybe there’s a BP30 in the works! :)

Thank for your post. I am planning to expand my system by adding amp and speakers and was not aurę od BHzA-1 would do the Job ad a pre amp. Seems it will.

Hi Zolty
It's taken some time, if you consider that I first suggested the idea of a head amp to James back in 2004
http://www.audiocircle.com/index.php?topic=13425.msg115324
Although rarely an early adapter I have a tendency to wait until the dust settles, patience does have it's reward.
So if you've been looking for the proverbial "straight wire with gain" the BHA-1 does a commendable job.
-
I was thinking about ATC SCM 11 (or 40 - room accoustics permitting), then option was either integrated amp ATC SIA2-150, or just a power amp hooked up to BHA-1.
I am not looking for any add:-ons from pre (bulb sound, extra musicality or so) thus will give it a try with both options.
Fortunately ATC dealer is flexible and would drive 150 miles with any equipment to let me audition in in my room. Priceless.
I'ok just ask him to take two pairs of columns, two amps and pile of cables.
Thanks for the info, at least I know it's worth trying with Bryston as preamp.
-
My Dynaudio Special 25s are tenacious at revealing any anomalies up stream, which speaks wonders for the BHA-1 and the BCD-1.

Also it just occurred to me that I can have my cake and eat it too, seeing that my HT setup is all unbalanced,
it’s just a matter of returning a balanced signal from the BHA-1 to the 4BSST and flick it’s input switches for critical listening. :thumb:
-
Thought I’d give some more listening impressions but with the Grado SR325i’s unbalanced stepping up to the bat.
(http://www.audiocircle.com/image.php?id=90273)
Sitting down with Einsturzende Neubauten double disc “Strategies Against Architecture IV” this evening I was bombarded with a vast array of arrangements and percussive instrumentation but what I noticed more than I have before was that the phones themselves were conspicuous by their absence.
As I mentioned before the BHA-1 appears to bring out the best in each head-set, the Grados this time doing the disappearing act, the recording existing within and around my head but my attention was never drawn to the phones themselves, much akin to having a system where loudspeakers disappear in the room. I then tried the AKG and Senns but with their larger casings (micro vibrations?) it was not as convincing but the BHA-1 still pulled this off more than I can remember with other head-amps.
-
Another perspective, I’ll give a detail comparison later.
The short of it though, the BHA-1 has little to fear but the .4 pre with the 2BLP pro does have it’s merits and the BHA-1 standalone or controlling the 2BLP pro are IMHO tied with inefficient phones.

I just ordered mine in silver. Can't wait until it comes here.
I've been using the WooAudio WA7 which is also a very nice amp.
I saw the Fosgate Signature amp at a local dealer and was caught the fever to try something new. :)
I went and listened to it today but over the week since I saw the Fosgate and today when I listened to it
some sanity was creeping in slowly.
So I decided I really should try the Bryston. So I first stopped off at another local dealer and plugged in my Audeze LCD-3.
Honestly, I am not the most discerning of listeners and most of the time I have a hard time identifying differences in equipment unless they are big differences and easy to hear. Well, this was one of those cases. The experience was really like hearing my Audeze headphones for the first time. It's as if I had not heard them to their full capability before. I tried several CDs and each time the experience was really good.
Still I thought I should listen to the Fosgate and so I went to the other dealer and listened. They were very good. But it didn't take me long to conclude that I couldn't identify what if anything made them more special then my Woo WA7. There was a similarity to the sound. The Bryston on the other hand though made me really feel I am in the high end of things listening to headphones. And I've been listening to headphones since the early days of Head-Fi for 15 years or more.
Can't wait till they come. Now to find a buyer for the WooAudio WA7 which I still do like and it really is very nice looking, but I need the money to pay for the Bryston. :D

Hello!
So the BHA-1 is a good preamplifier in your opinion?
I am considering of buying an amplifier but now I wonder if perhaps I should buy a power amplifier instead of an integrated one because perhaps the BHA-1 could be used as a preamplifier.
How is the gain like? Do you have to turn the BHA-1 all the way up or is it too loud even at 9 o'clock?
Cheers!

Hi Antun
Technically IMHO it is very very good and perfect for a minimalist setup.
The amount of gain will be dependent on the source, headphone/speaker efficiency and also if you are going balanced or unbalanced.
So yes depending on ones set-up, 9 o’clock maybe loud and with another combination one may find that the volume control will be maxed out, the later I would believe being applicable to headphones only.
A separate pre and amp offers the most flexibility, not necessarily always the best sound but more often than not, yes.

That's great Robert, thanks!
The one thing I think might be a problem is the lack of MUTE button on the BHA-1.. In other words, if I want to listen only to the speakers, I have to unplug the headphones. I am still not sure whether I want to do that

Yes problematic :scratch:, although most systems do mute the speaker output when headphones are engaged, and if you want to listen to the headphones you've to turn off the amp to the speakers, less problematic.
Just remember the BHA-1 was designed as a Head-amp first, the pre outs came as an extra after the initial production.

hi, Rob!
do you miss a remote for your BHA-1? would you say that this is a necessary part??

Hi Alex
My headphone set-up is right behind me, so no; but I would if I had to get up if it was across the room, how we've gotten spoiled. Next we'll be seeing all our music digitally stored so one never needs to get up to change a disc/record, mark my word. :lol:

For those who may feel the BHA-1 has limited inputs, especially for those who do not have balanced sources, I just wanted to point out that the balanced input will accommodate an SE source with a properly configured RCA to XLR cable/adapter.

Obviously this will not be a fully balanced system if you are using phones from the XLR outputs but the BHA-1 still sounds great either way IMO.

And if one wishes you can continue on to an unbalanced power amp from the BHA-1’s XLR pre-outs with one of these. (well 2 actually) :thumb:

I seem to recall from somewhere that using the BHA-1 as an unbalanced preamp, for example with a 2B-LP non-Pro, would entail connecting an XLR ground from pin1 and hot from pin 2 to an RCA plug while leaving pin 3 unconnected, in contrast with the typical practice of grounding pin3. Am I correct? I prefer to be sure before I try it.

Hi Jozsef
You may be correct on that one as the pre-outs are similar to the balanced headphone outs so ignore my suggestion about using the above config to an unbalanced amp, I'll delete the post until further word, maybe Mike at Bryston can clarify it.
I know it works with no problem using unbalanced signal to the the XLR inputs with the config I've shown above, as I've tried it.

Hi Robert!
Yes, I remember that BHA-1 was available only as a headphone amplifier in the beginning but they tell me only the first 100 units were manufactured this way.
It is an interesting story because I was looking for a headphone amplifier just when the BHA-1 was announced. I was interested even though I had no experience with Bryston and frankly, almost never heard of the brand. A good friend reassured me that Bryston was a no-compromise company. I contacted them and they told me I would have to place an order soon because the price was going to be increased by rougly 7%. I didn't even know whether I wanted the preamplifier functionality or not but they told me it would be good to have them because it would give me additional options of connection. They also made it possible for me to have the new version for the old price which was really remarkable. They actually suggested it! I placed an order and waited 6 weeks before it arrived at the dealer's. They called me and I drove 250 km to get it. I then discovered why it took them so long. The amplifier was made 3 weeks after the order was placed!! I suspect the demand was pretty high at that time and I remember James saying they can make 6 units a week. It may look industrial but it feels rather personal, just like their customer support.
I must say I noticed dramatic improvements when I connected the BDA-2 to the BHA-1 via balanced XLR cables. The difference in volume was obvious and I'd say at least 6dB because the gain switch on the BHA-1 compensates for the difference in volume quite precisely. I didn't do any A/B testing because that always fails so I just take my time and listen. I usually listen at very comfortable levels and sometimes for several hours. I can say with no doubt in my mind that balanced connection sounds more resolving. Instruments are more precisely panned and separated and the image sounds deeper and wider. No doubt about it, it sounds more realistic. However, the single-ended connection sounds a bit smoother in the mid-range which is a consequence of lower resolution because it doesn't detract as much from the composition. I am just saying this because I can see why someone would prefer it over a balanced connection.
I haven't tried a balanced cable yet and I don't know how big of a difference it will make, if any at all. I have the Sennheiser HD800 and was looking at the Sennheiser's own cable but the price is really very high. I was never much of a believer in cables and even with this improvement I have noticed, I still maintain it has much more to do with the type of connection / operating principle than with quality of the wire, though, no doubt, Bryston cables are very robust and nicely made.
Cheers!

I can tell you that I preferred the balanced headphone cable to the 1/4" phono plug cable. I'm not sure if the sound was actually better as much as it is louder (more gain, due to how balanced cables work) though. If you're feeling brave, you can cut the phono plug and re-wire your headphones with a $8 Neutrik XLR connector. :)
-
What I found, and it took me awhile, was that with the system balanced from input to headphones the sound stage is more naturally laid out. One would think that sharing the ground that things would be more centered but I found the opposite to be true, unbalanced the imaging is pushed more to left and right, fully balanced I’m getting a 180 degrees or better sound stage and depth.
Also FWICT using the balanced input with unbalanced phones is slightly better than balanced phones with a single ended input, balanced throughout being best though.

"Ok so I’ve had my Bryston BHA-1 all of 3 weeks and resurrected my life as a semi-serious head-fier after a hiatus of 5 years or so.
Spending hours with my past collection of phones; those being the AKG K501s, AKG701s (balanced), Senn HD 580s (600 grills w/ nylon mesh mod, balanced) and Grado SR325is, the BHA-1 bring out the best and the faults of each phone.
I like neutrality but find myself reaching more for the Senns, probably due to the encroaching winter months as they remind me more of cozy ear muffs :), but their rich (warm) mid-range and bass is currently more enticing than the others on hand.
The Grados and AKGs being more neutral sounding but still impart a signature, the AKGs have a more reticent, distant centre image with less bass, and the Grados falling behind the others but only because of the less expansive sound stage but IMO the better chameleon.
So here’s my gripe; with my speaker set-up running my Dynaudio Special 25s powered by a Bryston 4BSST and source Bryston BCD-1, each recording is distinctively different from tonality, sound stage, ambience etc, etc,
the Special 25s impart no overall signature of their own and make me feel I’ve been transported to a different venue or sound studio with each recording.
With each headphone I’m constantly reminded of their individual characteristics, not unpleasant but the illusion is not complete,
and without access or time to try all the current offerings I’d be interested to know which of the current offerings of headphones produce a similar disappearing act if possible.
Haven’t heard any of the planar models and my time with the HD800 was limited and not under optimum conditions, the new AKG K812s may be another contender or even the higher end Grados, so which ones should I focus on, I want it all though; staging/depth, ambience, focus and bass.
Keep in mind that a neutral system IMHO is anything but cold; a rich full bodied recording should be portrayed as just that but a Spartan, sterile performance ought to come across completely differently."

I have those same 701 AKG phones. So all I need to do is cut off the phone plug and wire a Nutric balanced connector to get the balanced performance from the phones? :scratch:

After few weeks out of the country, I returned and listened to music from CDP-1/BHA-1/HD800.
Must say that despite using non-balanced connections (both inputs and outputs of BHA-1) I enjoyed it a lot.
Funnily enough - I enjoyed it more now, than few weeks when I was testing some XLR IC. Must have forgotten already how much better it sounds when balanced. Anyway ordered (based on opinions only - without a chance of listening to ) balanced headphones' cable from Toxic Cables. When it arrives next step will be interconnect, then power cords.
One thing that came out - HD 800 are very open, i.e. "loud" outside. I am planning to buy additional headphones - this time closed design.
Would you have any suggestions - something that would match the system?

The HD800 has noticeably more sound coming out of it than other open headphones. This is because of the vented diaphragm design and the silver acoustic membrane on the outside which dissipates energy. The sound stage would collapse without it and it was designed in a way that the air surrounding the earpieces from the outside is also responsible for sound stage recreation.
It would be exceedingly difficult to find a suitable replacement in a closed pair of headphones. Out of the cheaper alternatives, AKG K550 are really very good but then, they are not in this class.

Hello!
I have a question for you guys on the gain switch. I have a Sennheiser HD800 and I have notices some differences in terms of tonal qualities between the low and high gain settings. The difference in loudness is obvious, of course, but long-term use of this amplifier has revealed that these two settings don't sound exactly the same. The low setting is slightly more calm in it's presentation. Quite smooth but perhaps a little bit loose-footed in the low register. The high setting loses a little bit of the subtlety in contrast but offers a slightly tighter bottom end.
Now, I am wondering if someone else has noticed any of these differences.
The HD800 is somewhat unique in that it is very consistent at any volume and I can't say their presentation changes when listening to them at a low or moderate levels.
If I am correct, then perhaps someone could offer an explanation. James perhas?
Cheers!

Was just asking myself the exact same thing, a few decibels can make the world of difference so I’m not too sure if it’s not just psycho-acoustic or a change in the impedance curve due to the resisters. One would invariable need to measure the voltage output to be sure, but the sound signature does appear “not to be” as radically different when adjusting the volume control to match levels by ear.

Hi Zolty
Personally I haven’t noticed a radical difference one way or the other, but all my phones, AKG701(balanced) /K501s, Senn HD580/600 (balanced) and GradonSR325is are now almost all considered old school, like my ears :( but each one has improved with the BHA-1. :)
Have a pair of Sennheiser HD700s on route, although it may be a while before I get them balanced but if and when I rewire them I’m curious if I’ll notice more of a difference.
But overall it’s been a month now since acquiring the BHA-1, each phone coming across distinctly different from any previous head-amp I’ve had, my appreciation just seems to get better and better with each listen.

Hi Antun
Did some more extensive listening, if you go from high gain to low gain and adjust the volume, psychoacoustically the change appears less. I'm now more convinced there is no difference, it's just that the volume control of the BHA-1 acts slightly different from what we are normally used to and needs more travel when adjusting for unity gain.
As I mentioned, a few dBs can make a huge perceptible difference.

>rob80b: Thanks for the information - I'll continue reading/searching through head-fi.
Regarding the difference between hi/low gain - well, I am not an experienced listener, most probably half-deaf (due to age and noisy work environment), but I my impressions are same as R.Daneel's:
On high gain, even with voulume turned down to more-or-less match low gain levels HD800 sound more dynamic, agressive, even harsh. Too dynamic, too harsh for my taste. Thats still with non-balanced connections as mentioned earlier.
It does not happen with low gain - even at max volume level, it is much calmer, smoother sound. Perfect match for me.
More like class A amp sound.
Well - maybe that's the case: not sure if BHA-1 goes class A all the way to max, or maybe it switches to A/B above certain levels (high gain)?

Have to double check the schematics to see where the the attenuation takes place, but there is the possibility in some cases where the source signal may be fairly hot causing earlier distortion on high gain at the pre or amp section of a setup. The only reason I say this is that I also use a 2BLP off the balance pre-ouputs a to power some phones and when I originally got the BHA-1 I sort of put it through a small torture test, I could get the headphone outs on the BHA-1 to distort before the 2BLP headphone output when set at unity gain, mind you that was way above safe listening with inefficient phones. All the same it may be perceptible in some cases and using the low gain keeps things within acceptable limits.
-
Thanks for your comments fellas!
One thing about me you need to know is that I never do A-B test. Unless it was a huge difference, I could rarely discern the subtleties in music while A-B testing so all my tests are done with long listening sessions. I usually listen at very comfortable levels and these levels are more or less always the same. I can say with certainty that there is a slight difference between the two gain stages.
It is possible this happens only in interaction with HD800 for example, I really don't know. But the difference isn't drastic at all.
I will have to say that BHA-1 has slightly too much volume with an HD800. At low gain, I rarely listen to music with the volume control turned above 10 o'clock. As you guys know, the volume has a rather steep volume increase from minimum to 9 o'clock and then a very mild increase in between 9 and 15 o'clock which allows for fine adjustment. With HD800 I would consider 10 o'clock at low gain setting to be loud enough with average recordings and HD800 isn't the most sensitive of headphones to begin with so perhaps a little less gain would be welcome in order to utilize the wide middle range of the volume control more fully. It is just an opinion.
See? These forums are a bad idea. Everyone has a right to an opinion and that includes me! :green:

Hi Zolty
That's quite possible and not your imagination.
Just to give an example, I have a pre-amp on hand that I’ve incorporated in my HT setup for bass management but the output of the BCD-1 is too high causing a similar situation. The use of a pair of 12dB in-line attenuators worked wonders where I can now increase the loudness way past the non-attenuated configuration, "even at max volume level, it is much calmer, smoother sound" .
-
Hi Zolty
One more thing, you can reduce the output of the BCD-1 by 3dBs by programming it with code 253, which may help a bit.
http://www.bryston.com/PDF/Manuals/300014%5BBCD1%5D.pdf page 3
I'm assuming you're now going fully balanced?
Well, my first post on this forum - although I've been reading this thread for a while.
A few weeks ago I bought BHA-1 and paired it with HD-800. Sound was so nice (although not yet perfect - working on cables), that I jumped head forward and bought second-hand BCD-1. I am sold to Bryston sound, and will be more when I switch cabling from RCA to balanced on both ends of BHA-1.
Just two things bother me - after reading how powerful BHA-1 is, I am finding myself listening with volume at 4-5 o'clock (un-balanced connections and with low gain setting). Am I deaf (might be the case ;) ), or is there something wrong with my BHA-1, or maybe that's how it is?
I know that high gain would help, but... unfortunately I can hear the SQ difference between high and low gain settings.
BTW Brystons are great sounding equipment, I wish I had suitable room to use pre+power amps+ some decent (ATC?) speakers.
I also recall when I first setup the BHA-1 I commented on the low gain with single ended inputs, I also remember that if I did turn the volume to max not only did the volume increase disproportionately but also distortion. :scratch:, so there may be something to my theory about overloading the amp section.
When using balanced inputs and because of the increased overall gain I assume most are using the low gain setting which obviously is not problematic.

I may have contradicted myself saying I heard a difference and now no difference with the gain setting on the BHA-1, but I've been trying different combination since acquiring the BHA-1 so I may indeed have the BCD-1's "-3dB " option currently engaged ', I'll check later.
-
rob80b: great idea about reducing BCD output and comparing. I played with the "253 code", but never really compared if the hi/low gain issue changes with reduced output. In fact coming from the theory that attenuator may impact BCD sound quality I left it at code "250".
Regarding increasing volume to max - I can hear slight "click" in sound when knob is about 5 degrees from max position, and at that moment voulume "jumps up" a bit. No like a gradual change, seems like attenuator contacts might have gotten dirty.
Anyway - I'll be home mid-January, by that time my balanced Silver Widow Toxic Cable will have arrived, so I'll test the issue a bit more.

Actually, the HD800's use the largest drivers than all other headphones and that is probably the notice of more sound. :thumb:

Hi Guy's,
I was just wondering if anyone had tried the new Audeze LCD-X and XC headphones on the BHA-1 yet?
I've got quite high hopes as the LCD-2's and 3's sound amazing on the BHA-1, I would say the perfect partners, and I have just got my LCD-X's and XC's for demo but unfortunately I have just sold my BHA-1 from demo so am waiting for a new one to come over, bad timing or what, they certainly look the part though -

I've really been enjoying my BHA-1 and my Audeze LCD-3's lately. Running balanced from in through out. Earlier in the year, I would have gladly sold my LCD-3's, because they just never felt like they were running at full steam. The Bryston is the first amp to wake them up and show me what they can really do. :thumb:

I couldn't agree more when I heard this combo at my dealer.
It was as if I was hearing my LCD3s for the first time in 8 months and I finally understood what all the fuss was about.
Still waiting for my BHA-1 though. 3 weeks now. I hope it makes it in this week.

Hi fellas!
Just out of curiosity, which S/N of BHA-1 do you have? Mine is slightly above 300 and I got it pretty early. Upon my order, it took six weeks for it to arrive and when it did, I was most impressed to see the manufacturing date was two weeks after the order has been placed. They told me they were flodded with orders which I have no doubts about.
They also informed me they were planning on using a different slope for the volume control and that they would make it more linear. I am not sure why because I think the volume control has been implemented really well already.
Cheers!

I've spent an hour or so listening to the LCD-X's and XC's and I actually seem to prefer the LCD-XC's which really surprised me to be honest as I always though that an open back design was the way to go, I don't know how Audeze have achieved what they have but the XC's sound more open than the X's to me, very odd.
Now all I need is for my new demo BHA-1 to arrive to try them together, definitely got very high hopes for that combination :)

How long did you guys have to wait for your amp to arrive?
I know it's the holidays but it's been almost a month since I placed my order.

With my luck they will probably show up on Monday when I go back to work and I got a super busy January coming up. :roll:

How long did you guys have to wait for your amp to arrive?
I know it's the holidays but it's been almost a month since I placed my order.
I've been at home for a week and was hoping they would have shown up.
With my luck they will probably show up on Monday when I go back to work and I got a super busy January coming up. :roll:

Hi Sanjay
Where are you located and whom did you order through - I will check.

I am demoing the Audeze LCD-3. I am using them unbalanced. What improvements did find going to the balanced mode?
Thanks,
BJ
I'm running Audeze LCD-2's via the balanced output. Due to the way a balanced connection works, the headphones sound louder than the unbalanced connection at the same volume level. I did not notice a sound quality difference, but I'm also using unbalanced inputs into the BHA-1.
If the cabling isn't introducing any noise in the signal AND the balanced/unbalanced circuitry is equal, balanced connections shouldn't really change the quality of the sound (from what I've read).

Hi Guys
I’ve been really enjoying chilling out with BHA-1/BCD-1 combo over the holidays and just added a pair of Sennheiser’s HD700 to the roster.
(http://www.audiocircle.com/image.php?id=92364)
Unfortunately I’m back to using one of my other head-amps for unbalanced sources, such as watching movies for example until I get a balanced cable for the HD700 to take advantage of the additional gain and even that may not be enough, and vinyl is out of the question with volume maxed out.
Anyone else having the same dilemma?
The 2BLP/.4 combo works great or even the 2BLP off the BHA-1 but it would be nice to to simplify the set-up and just use the BHA-1.
Or maybe just use the .4 as a source for additional gain between the tape outs of the main pre/avr and the BHA-1. (actually I haven't tried that.) :duh: , maybe not an ideal solution but one none the less!! :scratch:
(http://www.audiocircle.com/image.php?id=92365)
I'm sure Bryton's next pre will have a balanced tape out, HT pass through with bass management!! (right..James?) :green:

Ok, using the stereo outs of the AVP to an input on the .4 Pre and then the pre-amp outs of the .4 to the unbalanced line in on the BHA-1, with the gain fully open on the .4 has given me about a 6dB increase in volume. This brings the levels very close to the BCD-1s balanced outputs to the BHA-1.
Again not an ideal solution but it works........and I can now also hook up even more sources to the BHA-1 if need be.

Hi James
I have been really enjoying my BHA-2 for three months now. I just went to turn it on and the power LED stays red and there is no output. Checked the fuse and it is ok - any insights to the death of it?
Being in NZ, is this a return to base in Canada? I am kinda hoping that I do not have to wait for the distributor to wake up, send it to Aus, then to Canada and then back by Xmas...
Also, I am loving the BDA-2, but due to a muckup with the retailler, they sent me a black when I had ordered a silver and I would really like a matching unit to the BHA. Is it possible for me to retrofit this myself?
I am really enjoying both units BTW (matched up with HD800, Valhalla throughout).
cheers

Hi
It sounds like it may just have to be re-biased which the distributor can do quite easily. Changing over is not something you can do easily but I can have Mike Pickett send you instructions if you want to give it a try.

Hi All! Great thread.
I think I want to put a BHA1 after a preamp, but worry about having two volume controls in the path.
Seems like most people are attaching the BHA1 directly to a source and some use it as a preamp. I can certainly appreciate how that puts the headphones as close to the source as possible.
But for me, since I have four sources and enjoy using a regular preamp for source selection and (remote) volume control, it really is tempting to place the BHA1 after the preamp, driven by outputs that follow the gain stage and volume control.
I wish there was a switch to take the volume control out of the path on the BHA1. Would this feature be possible to add? Am I the only one who would enjoy this additional flexibility in hook up options?
Without a full bypass, what would be the recommended setting to place the volume control knob so as to reduce its influence as much as possible? All the way up? Noon? Something else?
Thanks!

I tried it again yesterday and now it works fine... If it happens again, I will arrange sending it back to the distributor for a checkup.

See my above post but depending on the output of your pre and if you wish to use it's remote volume control it may be as simple as using the BHA-1 at full gain, I did this with a Bryton .4 pre (no remote) I have on hand with no problems, I did gain the ability to switch between multiple sources and bit of additional gain for low output single ended sources.
The only hurdle is if you switch between inputs on the BHA-1 and if some are direct from sources (especially balanced), just remember to lower the volume on the BHA-1.
If you decide you do not want/need remote volume and your pre has a tape out, use that and then control the volume from the BHA-1, I've tried both set-ups.

What are you finding are you favorite headphones with the BHA-1? I really love the Audeze LCD-3 combo, but for some reason my inner ear starts itching badly every time I listen for more then 15 minutes. Because of this, I'm finding it very hard to enjoy the rig. I'm starting to look into other phone options because of this issue.
-
I have Audeze LCD-2's and have never had any problems. Interesting....
I hate to broach what some consider "snake oil", but perhaps a change in headphone cables?
-
My favorite are the LCD-3,I like Sennhieser's HD800 but they don't have the bass of the LCD-3. My Hifiman He-500 seem heavier than the Audeze.
-
I actually sold my HE-500's to buy the LCD-2's, with which I'm much happier. The HE-500's were very detailed, to the point of disengaging me from the music. Most dramatic example was Michael Jackson's "Thriller". Obviously, there are several synthesized effects within the song. The HE-500's made that synthetic effect VERY obvious. Those sounds and effects felt very "apart" from the music. Heck, some of the instruments sounded "apart", like they were terribly misplaced in the sound stage and of different quality. That is probably accurate, but it wasn't what was intended to be heard by the listener.
The result was that I focused on the inconsistencies in the recording and stopped enjoying the music. The LCD-2's had all of the detail, silkiness, and musicality I wanted. I literally found myself tapping my toes to the music. I also found them to feel lighter, sit easier around my ears, and be more comfortable in the headband. All of this was with the balanced output of the BHA-1 (BDP-2 -> AES/EBU -> BDA-2 -> unbalanced -> BHA-1. I also find it an unfair comparison; the LCD-2 is several hundred dollars more expensive.
And it wasn't just pop music like Thriller; however, the better the recording, the less pronounced the effect. But the HE-500's never did get me toe-tapping. That said, what sounds pleasing to me may drive someone else nuts.

Hi, I have any question:
I'm thinking to order a new BHA-1; since I own a MPS-2 (connected to my BP-26), is it better to buy it without internal power supply?
I should like understand if there is a real sonic difference between the two configurations (internal or esternal power supply).
I am also undecided because BHA-1 without internal power supply will be usable only connected to the main system and not independently.
Last question: is price the same?
Regards
Roberto

Hi Roberto
We no longer offer the BHA without internal power supply. We found external offered no real performance advantage and no real costs savings and the down side is you have to use it with the MPS-2 which limits its use and resale value.
james

I think the BHA-1 is sensational. I think it is on a level that cannot be superseded and something of a timeless value that can grow with your musical aspirations, experience and your system. If Bryston ever improves upon the design, I might purchase the new model but this one will remain where it is. It is the best piece of equipment I have ever bought.
Cheers!

Hi James and congratulations!
I have to mention that Mr. Edvard Potisk helpmed me resolved many concerns that I had before setting on Bryston equipment. As a matter of fact, I shall be placing an order for the BDP-2 shortly and will need his assistance once again! He's quite a gentleman and I hope this letter of praise finds it's way back to him. Not that he doesm't know it!

Congratulations James, the BHA-1 is easily the best Headphone amp I have heard, and we've got a few in here now, and is actually one of my best selling products, it is definitely the amp that any new comers have to go up against.
I have used it with everything from Sennheiser to Grado, Fostex, Audeze, HiFiMan, Beyerdynamic and it gets the best out of every pair of headphones I have tried :)
Well deserved :thumb:

Hello!
I have a question for BHA-1 and Sennheiser HD800 owners. I am interested in purchasing this balanced cable:
http://en-de.sennheiser.com/dynamic-headphones-high-end-around-ear-hd-800
It is the Sennheiser CH800S balanced cable that uses a 4-pin XLR connector.
Am I safe to assume this cable is compatible with BHA-1 amplifier? I cannot find a picture of the pin arrangement on the cable anywhere so I do not know whether this will work properly with Sennheiser HD800.
Any comments would be appreciated!
Antun
-
It looks like it should work fine.
-
I just recently purchased a bha and hd800. The bryston has both a 4 pin xlr output and 2x 3 pin xlr output (left and right). I am using the 3 pin xlr myself. The sennheiser 4 pin xlr will work with bha.
-
I've recently been using Toxic Cable's Silver Widow headphones cable with 4-pin XLR and everything is OK. Thinking about purchasing Entreq Challenger for HD-800 - just to 'soften" them a little bit.

Hi Antun,
I also run the Sennheiser balanced cable with HD800's on the BHA-1 and it works perfectly, gives a real nice lift in overall dynamics compared to the stock single ended cable, well worth the money especially if you run a balanced source into the BHA-1 as in my opinion running a fully balanced headphone rig is the way to go if possible.
-
See my above post but depending on the output of your pre and if you wish to use it's remote volume control it may be as simple as using the BHA-1 at full gain, I did this with a Bryton .4 pre (no remote) I have on hand with no problems, I did gain the ability to switch between multiple sources and bit of additional gain for low output single ended sources.
The only hurdle is if you switch between inputs on the BHA-1 and if some are direct from sources (especially balanced), just remember to lower the volume on the BHA-1.
If you decide you do not want/need remote volume and your pre has a tape out, use that and then control the volume from the BHA-1, I've tried both set-ups.
I'm thinking of acquiring a BHA-1 and would want to connect to the tape out on my BP26. Does the volume control on the BHA-1 achieve the same volume at the same setting as it would connected single ended directly to a source component?
-
My new BHA-1 is connected as you say (BP 26 tape out). I also tried to connect it to my BDA-2: to my ear the volume level is the same. While You have a higher level of volume if you connect headphone to xrl output instead of unbalanced output.

Hi Guys,
I have just got the Abyss AB-1266's in here which are the first pair of headphones that I have experienced with single balanced left + right inputs, needless to say the first thing I did was plug them into the BHA-1, yet again the BHA-1 delivered, I have tried them on a couple of other amps but at the moment the Abyss + BHA-1 is a winning combo and pretty much the best headphone rig I have ever heard :thumb:

James,
Yesterday my 1 month old BHA made a recording screech and then shut down while changing the green led to red. I disconnected the power plug and let the unit sit for hours. This morning I plugged it back in and it's working normally. I couldn't find anything in the user's manual to explain the episode so I next thought to post here to get some direction. The BHA is sitting on top of my BDP and BDA, it is the top unit and the sides are open to air flow as is the rear which is greater than 6 inches from the wall.
Thanks

It sounds like it overheated? If it happens again see if the chassis is too hot to touch. If so the bias needs to be adjusted.

You do not mention how much space you have from the top of the BHA to the shelf above. Most of the cooling is from the top surface. If it is too close you will definitely have an overheating issue and it will do exactly what you described. This is from personal experience. I moved my BHA-1 so that I had almost 3 inches of space above and have not had the problem since.

Tony,
Thanks for the support. There is no shelf on top of the unit only a ceiling 6 feet above and I failed to mention it sits on my credenza 2-3 feet from an open window so I'll be shocked if it overheated with a room temperature of 76 degrees. My headphones in use that day were 300 ohm Sennheiser HD 650's and the volume never exceeds 9 o'clock @ the high gain setting. Hope this provides a more complete picture.
Now I'm wondering if one can adjust the bias or do I have to ship this back to Bryston? Do you know? Seems a shame on a virtually brand new unit.

Could sun from the open window be the cause of the overheating?

Sorry, no, I leave that stuff to the professionals.
-
But why would an amplifier need bias adjustmnet after it has been adjusted in the factory?
My tape machines require bias adjustment (typically called realignment) but this is needed only periodically to ensure the machines are at factory nominal values (and thus allow compatibility with previously recorded tapes).
With respect to amplifiers, does the bias change with temperature or something?
-
What are you finding are you favorite headphones with the BHA-1?
My current go to and chill outs so far are still the Sennheiser HD700s, much prefer them over the HD800s for long term listening and overall musical enjoyment.

Hi Guys
Having since sold off my 2BLP pro which ran off the BHA-1s balanced pre outs to run a second pair of phones in tandem I’ve been in contact with Mike at service to see anything could be done to modifythe BHA-1 to allow the use of two phones at once, balanced and single ended, which obviously require different gains.
Anyway thought I’d throw this at you and see what James has to say.
Basically it is a BHA-1 having two 4 pin XLRs, (much more convenient IMHO than using two 3 pin XLRs) but one with an independent gain allowing it to be adjusted with regards to another balanced or unbalanced headphone when used simultaneously.
For me this would be a big plus as many headphone users have more than one phone and or a significant other to listen with and also having the ability to adjust for unity gain between two sets is a great comparison tool (which I believe a lot of us do all the time :D)

Hi Rob!
Did you make the photo yourself or is it an actual modification of the BHA-1?
It would perhaps be a good idea for Bryston to consider an additional headphone amplifier. One that would employ their latest volume control because it is that much more important with headphones to have a accurate channel tracking and I would also like to see relay-based input switching.
Just for the psycho headphone maniacs like us!
-
Hi Rob!

Hi Daneel
Just me day dreaming with a little P.S..... but maybe someday. :D
-
Greetings!
I plan to use BHA-1 with a DAC that has XLR outputs at 6.8Vrms, which is higher than a typical ~4Vrms. Will that be a problem for BHA-1?
-
I guess will depend also on your headphones
I have BHA with HiFi Man HE-500, input on XLR from the Bryston DAC, low gain and I find the BHA providing very high volume at very little turning the knob (I listen between 8 and 9 o'clock and I find it loud to very loud especially with nowdays recordings)
-
I'm seeing the BHA-1 now being called the BHA-1F. Anybody know what the F stands for and how it differs from the BHA-1? For example that's what Audio Advisor is calling it.
-
As I recall the BHA-1 could be ordered with male or female connectors on the front face. Audio Advisor is differentiating between the two with a letter. Female is most common.

Sorry if this has already been discussed...I didn't read through the 42 pages yet...has anyone compared the Soloist against the Bryston BHA-1?
I just finished reading the 100 pages of the Bryston thread and to my surprise not a single comparison between the two amps, which I find odd since they are not too far apart price wise and both seem to have excellent reviews.
Anyone had both at the same time for direct A\B comparisons?
Thanks.
-
Hi folks!
I was just wondering what you guys think of pairing the BHA-1 with a headphone from Grado labs, be it GS1000 or PS1000.
I must say I spent some time with the PS1000 but it was with an OTL tube amp and I was not really satisfied. For some reason, the mid-range seemed rather recessed to me.
What I am looking for is a headphone for quiet listening. I have the Sennheiser HD800 and it's awesome but to get the best out of it, the volume level has to be moderate and sometimes this is a bit too loud for me when I am listening to music in the evening. So, I would like something that sounds excellent at low volumes.
Is there something you would recommend to me? How would the new AKG K812 fare in this game?
Best wishes,
Antun

I tried (and really wanted to love) Grado. I went through those, HifiMan, and ended with Audezee LCD-2's. I LOVE mine. But, as with flavors, what one person likes, another may not.

Based on the my experience w/ the other 2 headphone amps that I have (both tubed) I would say that my Soloist "Errs" on the slightly
"cool" side (& I do mean slightly) of sounding "neutral".
I listen to various types (mostly Orchestral) of Acoustic music almost exclusively. While the Soloist will sound very detailed & gives you a
very good sense of 'dimensional sound' it could use just a touch of 'warmth' to bring you closer to the music rather then the "sound" of the "recording".
I met a retail Bryston dealer who will be bringing in the BHA-1 in the near future, I've been curious myself so I'll take my HiFiman HE-6 in to give it a listen

Hi Garret!
Thanks for your comment!
I have noticed that many people like Audez'e headphones due to their low-end extension and gentle high-end that seems not to discriminate lower quality recordings. Would you agree with this observation?
Would you consider the Audez'e a good headphone for low-volume listening?
Cheers!
Antun
-
With the BHA-1, I find it pleasant at all volume levels.
In comparison to the HiFiMan HE-500's, the Audezee's were just more musical. When listening to the HE500's, I always ended up focusing on some portion or instrument of the song, never the whole piece. By way of analogies, it was like watching a movie on an LCD television with the soap opera effect. It was very detailed, but it just never managed to capture me emotionally. The LCD-2's though... I instantly found myself tapping my toe and bobbing my head. Everything became cohesive and it just sounded more like music to me.
Perhaps consider The Cable Company, which (for a price) will allow you to borrow even headphones before you buy them.

With the BHA-1, I find it pleasant at all volume levels.
In comparison to the HiFiMan HE-500's, the Audezee's were just more musical. When listening to the HE500's, I always ended up focusing on some portion or instrument of the song, never the whole piece. By way of analogies, it was like watching a movie on an LCD television with the soap opera effect. It was very detailed, but it just never managed to capture me emotionally. The LCD-2's though... I instantly found myself tapping my toe and bobbing my head. Everything became cohesive and it just sounded more like music to me.
Perhaps consider The Cable Company, which (for a price) will allow you to borrow even headphones before you buy them.

Hi Garret and thanks for the reply!
The LCD-2 seems rather nice I must admit. Do you run your headphones single-ended or balanced and which ear-pads are you using, leather or velour?
I have seen some FR graphs and am a bit concerned about the roll-off in the top-end because I listen to a lot of classical but then, I really don't know how those measurements translate to real-life performance and whether this roll-off is even noticeable.
Cheers!

Hi Antun
It was one of the issue I was surprised at when I was developing the BHA-1 headphone amp as to how varied the frequency response of the different headphones were. It may explain why there are so many different preferences and opinions about the listening experience. :scratch:

Hi James!
I see your point!
The FR graph of the Sennheiser HD800 is very flat and to my ears, they are the flattest transducer I have heard to date and this includes loudspeakers. With the BHA-1, the tonality is virtually spot-on realistic, no matter the what kind of instrument is being reproduced. Obviously, Sennheiser did it with the HD800.
Every person will have his or her opinion on the sound. Still, that doesn't mean we should change the laws of physics just to accomodate one's opinion and make it the "right" one. Equipment can either sound realistic or not, there is no other basis on which one can evaluate it. I have to tell you I searched hard and it took me 2 years to finally set on a pair headphones and then another year to find the perfect amplification for it. I always go back to my sudio recordings and live memories from the various places I played at and then I know whether it sounds as good as the real thing or it doesn't. But many, many people don't have such experiences, no point of origin, so they might get impressed by something that is farther away from the truth and in some cases, the truth isn't at all what they consider good sound.
Some manufacturers try to imprint their signature on the sound of their headphones just to stand out a bit from the crowd. That is fine of course but ultimately, it doesn't get you anywhere because someone else might say his way of doing it is the right one. The peril of this approach is compatibility. There is just no way equipment can sound good with everything if it puts it's own imprint on the sound it reproduces. Genuine neutrality is the only way to achieve this compatibility.
The BHA-1 is an utterly flat, color-free and linear-sounding amplifier. It is linear in a way that FR domain is accurate but more importantly, it is accurate at all volume levels and this has proved to be it's trait that is impossible to find elsewhere.
So, I understand your troubles but you did well and "sanity" and engineer's approach are always a good thing if you ask me.
Best,

I agree and ultimately came to the same conclusion for the BHA -1 ... make it as neutral as possible otherwise we end up in this arbitrary circle.

You bring up a good point. Most of my listening when I bought the headphones was pop/rock with jazz thrown in here and there as well as movies/TV. Aside from some of the jazz, most of those recordings are probably not very true to the original sound, thanks to all the processing. So, I like the Audezze's for what I was listening to at the time.
I did try the Sennheiser HD700's, which have a similar flavor to the HD800's and found them to be dry. Prior to all of this, I have used Sennheiser for over a decade. I love their comfort and the sound of the old HD590's (if I have the model number right). I still have a few sets of much lower priced Sennheiser's and I always enjoy them. I also did get to listen to the HD800's when they came out. At the time, I thought they were the best headphones I had ever heard, but a tad lacking in bass. From what I've read and heard, they may be the better choice for classical.
I use the leather ear pads and a balanced connection.

Hi Jim,
I have gotten into headphones in the last couple of years, as I ran out of suitable room to get the kind of sound I wanted for my Thiel 3.7s. I have them in storage, but hoping to put the big Bryston 14bsst2 on them one day.
In the meantime, I am listening to headphones (Audeze LCD-3s) and I just added your bha-1 headphone amp on them and wow what a difference! I upgraded from a Schiit headphone amp which was good, but nothing like this. It seems to have plenty of power even on low-gain mode.
I like the Byrston sound - straight ahead, no embellishment, very detailed and honest, which is what I like.
Regards,
David

Hi folks!
I was just wondering what you guys think of pairing the BHA-1 with a headphone from Grado labs, be it GS1000 or PS1000.
I must say I spent some time with the PS1000 but it was with an OTL tube amp and I was not really satisfied. For some reason, the mid-range seemed rather recessed to me.
What I am looking for is a headphone for quiet listening. I have the Sennheiser HD800 and it's awesome but to get the best out of it, the volume level has to be moderate and sometimes this is a bit too loud for me when I am listening to music in the evening. So, I would like something that sounds excellent at low volumes.
Is there something you would recommend to me? How would the new AKG K812 fare in this game?
Best wishes,
Antun
I got the PS1000 on sale from a dealer that was waiting to get the new 'e' series models a few months ago.
I had the cable converted to balanced.
Sounds quite superb with the BHA-1.
I did have to lower the output level (via an internal jumper) on my Benchmark DAC2 otherwise it would get loud very quickly.
But then so do my HD800 and Audeze LCD3. They all sound great with the BHA-1.
I just have to decide which sound I'm in the mood for as they do sound different.

Hi folks!
I finally connected the HD800 with it's CH800S balanced cable. I bought this cable months ago and never really used it till just a few days ago. The reason for that was to spend as much time with the stock cable and then be able to compare it to the balanced one. Replacing the cable is a bit of a problem because it isn't easy to disconnect.
I am now listening to some recordings and I must say the improvement is definitely there. The most notable one is increased resolution of the subtle nuances and detailes of the instruments and vocals. However, I must also say I am hearing improvements in dynamics. It seems more dramatic and the differences between quiet and loud passages are obvious. Fingersnaps are more detailed for instance.
I won't say this is due to the cable though. I am keen on believing the amplifier works to it's full potential this way.
Can you share your own experiences if you have any?
Also, is there anyone who uses the new AKG K812 with the BHA-1?
Cheers!

The balanced outputs don't defeat when you plug in headphones.
If there is a new version of the BHA1 sometime this would be a nice feature.
In the new house we moved to recently I setup my desktop system with the BHA1, Benchmark DAC2 and my headphones.
But I also got the Paradigm Shift A2 loudspeakers which sound great.
I decided to take advantage of the BHA1 outputs to drive the loudspeakers.
But in this case it's a dual use system. I want to use it with my headphones and other times I want to play the loudspeakers.
Unfortunately when I plugged in my headphones a couple of days ago the loudspeakers were still playing.
I will have to plug them into a dedicated power bar which I can use to power the loudspeakers off and on.

Hi Sanjay
Yes the Balanced OUTS from the BHA-1 are in parallel with the headphone outputs so there is no way to mute one over the other.

I'm very happy with the sound of my BHA-1 driving balanced Sennheiser HD800. (Source is BDA-2 DAC, fed by either Sonos for streaming services or recently acquired BDP-2 for attentive listening and high-res.)
If I could ask for one thing, it would be a greater range of control when adjusting the volume. Even with the BHA-1 on low gain setting, I find that with the HD800s, things get pretty loud when the BHA-1's volume control reaches just past 9:00, and then even the slightest nudge of the volume knob can lead to a big leap in volume.
As far as I know, I can't decrease the output level of the BDA-2 DAC, but maybe there's a way that I'm not aware of.
But to reinforce the initial positive point -- to me, the BHA-1 does a great job when driving the HD800s balanced.

Hi!
You can decrease the BDA-2 output level by 3 dB if you have the BR-2 remote control.
Also, I am not sure why you say the volume on the BHA-1 increases when you get passed 9 o'clock because on my BHA-1, the volume raises very gradually from 9 to 15 o'clock as it has a very "mild" middle range.
A few years ago I talked to James Tanner and he said Bryston was planning on replacing the volume control with a linear type. DId they do this? Does anyone know?

I say it because that's what happens on my BHA-1 in my setup. You may have a different experience, but I'm reporting what I observe. The basic point is that in my setup the volume control does not offer enough range of control for variation in level.
-
You're welcome...

You're welcome...
Oh, right, thanks for the tip about the BR remote -- but ouch, that's a costly little device.

We can lower the output of the BDP but it needs a resistor change.

Hello,
This is pretty interesting for the fact that I've had the same type of "running out of adjustable gain" issues with at least 4 different hp amps
while using the HD 800 headphones. The thing that I find most peculiar is that the sudden jump in gain occurs at about the same place it
seems it does for the gentleman above ... just a bit past 9 o'clock !
I'm begining to believe that this sudden gain "intolerance" has more to do with the HD 800 than it does with any associated equipment that might be being used with them. Could this have anything to do with the 800"s impedance "curve" transition not being gradual enough ?
I'd be curious to know if persons who have had their HD 800 straightwired to the headphone cable they're using have a smoother
,more gradual volume changes ? Don't get me wrong my HD 800 still sound fantastic but they're a little more work then other headphones
to find the volume "sweet spot" !
I should state the disclaimer that my signal chain does not include Bryston equipment (though the BOT-1 looks very interesting) but
the circumstances of the reported volume issues are all too familiar to myself. I think Sennheiser can be a bit "wanting" in some of their
"Design" implementations.
-
I don't believe is particular for HD-800
I experience similar loud sound when volume is above 9 o'clock and I own HifiMan HE-500, and I believe the same behavior was reported by others in this thread
-
Hello,
...............
I'm begining to believe that this sudden gain "intolerance" has more to do with the HD 800 than it does with any associated equipment...................
I’ve had similar experiences with my AKGs, Sennheisers and Grados so it’s not the HD800s.
There were a lot of previous discussions concerning the volume adjustments....too little…too much, high/low voltage outputs from different sources…balanced ….unbalanced…affecting the travel restrictions with regards to adjusting the volume.
Believe James explained it was to accommodate the numerous sensitivities of different phones.
“Hi Folks,
Yes the volume control is designed as the above because we felt given the large amount of Current and Voltage output the BHA is capable of we wanted a very broad range in the middle to allow for the huge variation in efficency headphones have.
James”
Basically it’s not your traditional linear volume control, at least when using headphones, depending on your source; I had problems achieving enough gain to power my inefficient AKGs and some Sennheisers running a single ended connection from my AVP for movies so that the control was almost maxed out and then that last little bit, lets say 5:30 there’s an exponential jump so that it was then too loud…… running balanced from my BCD-1 the volume is rarely above 9 o’clock.
I’m now running most sources from the tape out of my current preamp, which has a slightly higher output but….. I’m running the single ended output with a single ended to balanced adapter into the balanced input of the BHA-1 so that I’m more or less around 10 o’clock now on the dial for most sources and oddly much more room for fine tuning.
Now I mentioned “at least when using headphones” as when the BHA-1 is used as a preamp I find the gain structure powering speakers acts in the more traditional linear fashion with no major jumps in volume.
Bottom line is that headphones vary too widely in efficiency, current draw, 32ohm?..300ohm?...... but the BHA-1 manages to do a fairly descent job with most of them. :thumb:

Hi!
You can decrease the BDA-2 output level by 3 dB if you have the BR-2 remote control.
I looked into getting a BR2 remote to decrease output on my BDA2 DAC, but found out it can't be done, according to this e-mail just received from Mike P. at Bryston:
"The ability to reduce the output was available on the BDA1 DAC, but only by
3db, and only because it had rather high output (2.3V). Since the BDA2 has
a lower output (1.9V), this feature was not included."
-
Perfect timing! I just programmed it into my remote and was wondering what I did wrong. :D
-
I am looking at either Sennheiser HD800 vs Audeze LCD-2 as my next headphone. I know there are plenty of threads on the internet, but basically I cannot try either before buying, the nearest dealer would be a 5+ hour round trip.
I like the LCD-2 just comes standard with a balanced cable, and a hard carry case, etc and actually look very nice with the wood finish, the HD800 don't actually look like expensive headphones because of the design and plastic, but then there is the issue? of the LCD2 cracking.
At any rate they cost about the same where I am, except as I said I would have to buy an additional balanced cable for the HD800.
Can anyone comment on which headphone has better synergy with the BHA-1 out of the above two models? And is the cracking really an issue or fairly isolated?
-
I love my LCD-2's (no cracking/damage ever/whatsoever). I also tried the HD800's. I REALLY think it's a matter of what type of music you most frequently listen to. The BHA-1 sounds great, regardless of what you use with it.
-
The BHA-1 is an extremely balanced amplifier and it's power delivery is quite linear meaning all the frequencies are amplifierd equally so even at full volume, the sound is very consistent. In that respect, it will work excellent with any headphones you might wish to use with it as long as the impedance of those headphones is sufficiently high.
If HD800 and LCD2 cost the same, then you have to decide for yourself. I will tell you this though - the transient response (the attack and drama) as well as detail resolution and spatial imaging is way better on HD800 than even the LCD3. If that is something you like, then HD800 is your candidate. If you like more pace and added extension in the low end as well as withdrawn top end, then LCD2 will be more to your liking, especially because it will be more forgiving with average recordings.
The HD800 is built to a much higher standatd than the LCD2 and LCD3. The point in fact is, the materials used for HD800 are composite and believe me, I know something about these. They will last. I have not heard any complaints regarding the Sennheiser, especially the HD800, whereas I have heard criticisms about Audeze's quality more than once.
Hope this helps!
Post a picture when you make a decision and buy something!
Cheers!

Hi Folks!
I just got the Bryston BHA-1 yesterday and had it hooked up for a listen - boy its good!! :thumb:
Its currently hooked up through balance inputs from the CDP but even with Low gain I can only get the volume knob to 9 O'Clock at comfort listening levels. Will changing the inputs from the CDP from Balance to Unbalance improve this? Also which sound best - Balance or Unbalance? Any votes?? :)
One more thing here is the LED turned to Red after few hours of used and the unit wasn't very hot either - similar to my 4BSST2. i didn't know what or why and switches the BHA-1 off for a min and turn back on and its Green again. I never experience the same with my 4BSST2 and in fact I never turn my Bryston 4B off at all! I read the manual and found this statement below but I am not using the MPS-2. Any clue what is the issue here?
STATUS LED
LED lights green when the BHA-1 is turned ON. When the BHA-1 with the external pow- er supply option is properly connected to an MPS-2 external power supply & the MPS-2 is turned ON but the BHA-1 is turned OFF, the LED will light red to indicate that external pow- er is available.
Hope to get some help from the experts here and if James can comment on these too.
Many thanks! :D

Hi Larevoj
Does the BHA-1 have proper airflow as it is a Class A amp, if so I’d contact Bryston’s service Toll Free: 1-800-632-8217, the led should stay green…may just need a bias adjustment.
Single ended from the CDP will lower the gain but balancing the headphones will then increase it by the same amount, if you have a BCD-1 you can also lower the gain with the remote also by 3dBs with code 253.
As for a difference between using an unbalanced or balanced cable for the headphones some have reported a large improvement…it’s possible… although I’m more inclined to believe it’s the extra gain which can make a huge difference in perceived performance if levels are not matched exactly…especially with inefficient phones, which phones are you using?
Either way it's a great Head-amp. :D

Hi Robert, thanks for the respond :)
Yes, I have sufficient air flow and its on an open rack too. I think the critical clearance is actually the bottom of the unit where the transistors are mounted and the cover on the top acts as an extended "heatsink" albeit not an ideal one. I wonder why Bryston did not flip the board upside down so the transistors are on the top and a proper heat sink can be mounted to increase its efficiency...just thinking out load. It hasn't turn red since I switch it off and on...this makes me wonder if the BHA-1 can be kept in 'on' position like the 4BSST2.
I was referring to the balance and unbalance inputs from the source...I have placed an order for the Audeze LCD-3. :D Is this a good match? Which is the best?
Thanks.

Ok…In my case yes as I’m running 30’ of cable from the front of the 15’ room to the back for the BHA-1, single ended I picked up a bit of hum, balanced no noise at all.
Haven’t heard the LCD-3 but believe there are a number of satisfied users with that combo that have posted in this thread.

LCD-3's and BHA sound fantastic together. You should be very happy.

I love my LCD-2's on my BHA-1. Not quite the same, but in the ballpark!

I want a Bryston Headphone Amp (BHA-?) with Remote Control Volume....Please, Please, Please.
ALL of my music sits in my BDP-2 player....(plus, a few backup drives). My setup is across the room. Need Remote Control Volume.
I would like to get into headphone listening. Over time, I can see myself with different Headphones with different cables, etc. Front panel connection choices of BHA seems to fit the bill.
But, I want a Bryston Headphone Amp (BHA-x) with Remote Control Volume....Please, Please, Please.
James,
I am gonna buy something. If you give me a hint that you are planning a Bryston Headphone Amp (BHA-?) with Remote Control Volume, I will wait.
...have i said "Please" enough?

Yeah, a volume control and maybe an un-volume controlled pass through would be nice.

I use HD800,the LCD-3 and HiFiman HE500. I mostly use the HD800 or the LCD-3. I find on well recorded music I tend to use the LCD-3. The can's have slightly deeper bass and not as bright a top end. On more poorly recorded music I use the HD 800. They tend to get every nuance but they can sound a little bright on some recordings.
I gave my son my Sennhieser HD600 and my HiFIMan HE500 collects dust.
-
Thanks for the feedback guys, I ended up going for the lcd-2 - this is after going back and forth in my mind about 100 times. What made my mind up in the end was that quite a few reviewers had mentioned the tendency of the hd800 to be a little bright and possibly a bit fatiguing if used for some time, whereas the lcd-2 had slightly more lower end.
I'm happy with the choice, but the lcd-2 are HUGE, something you can't tell from looking at photos on the internet. The wood and leather finish is very pretty too.

I am very confident that it will run 24/7 with no issues whatsoever just like their renowned SST2 amplifiers. Also the BHA-1 does benifits from HifiTuning Supreme fuse if you are keen to try...Cheers!

Hi Folks!
I just got the Bryston BHA-1 yesterday and had it hooked up for a listen - boy its good!! :thumb:
Its currently hooked up through balance inputs from the CDP but even with Low gain I can only get the volume knob to 9 O'Clock at comfort listening levels. Will changing the inputs from the CDP from Balance to Unbalance improve this? Also which sound best - Balance or Unbalance? Any votes?? :)
One more thing here is the LED turned to Red after few hours of used and the unit wasn't very hot either - similar to my 4BSST2. i didn't know what or why and switches the BHA-1 off for a min and turn back on and its Green again. I never experience the same with my 4BSST2 and in fact I never turn my Bryston 4B off at all! I read the manual and found this statement below but I am not using the MPS-2. Any clue what is the issue here?
STATUS LED
LED lights green when the BHA-1 is turned ON. When the BHA-1 with the external pow- er supply option is properly connected to an MPS-2 external power supply & the MPS-2 is turned ON but the BHA-1 is turned OFF, the LED will light red to indicate that external pow- er is available.
Hope to get some help from the experts here and if James can comment on these too.
Many thanks! :D

I had the red LED issue on several occasions and the BHA-1 wouldnt power up. It was really random and it would work fine for weeks and then simply not work for a week or so. The retailler sent it back to the local Bryston approved agent, who faffed about on three occasions changing (I think) bias resistor values.
On the 3rd return, I was fed up and demanded a replacement unit -which they agreed to.
However, I was in Vegas (over from NZ) a few months ago and purchased a Woo Audio WA22. Wow more like. I really enjoyed the BHA-1 with my HD800s, but the WA22 is something else again. I think it is a better match for the 800s. Still keeping the BHA-1 in the meantime though.
-
wow...thats unfortunate! I hope the new unit fix the issue for you. So far I have been driving the amp hard and not a single glitch thus far and have only seen it once. The only gripe I have is its gain and I never seems to be able to get pass 9 to 10 O'clock. I doubt there is any dip switches I can adjust and this is the same even with Bryston BP26 through speakers output. I am not sure why Bryston set its volume gain so high.
I am also considering a tube amp for a different flavour and thinking maybe Leben CS300XS...
Cheers!

question: is it safe to both plug in and unplug headphones while leaving the BHA-1 turned on? or running it with no headphones attached at all?

Hi James,
Regarding the volume control on the BHA-1...I seem to recall reading that, up to a certain point on the volume control, the amp is actually operating at unity gain. Is this true? Of course, I can't find a post where this is written, so maybe I'm not remembering correctly. :D
-
That'd actually help me... a unity gain would allow me to use my SP3 as the volume control.

Hi James,
I thought I'd take the time to tell you I received my BHA-1 and am blown away. The build quality is truly excellent, switches and volume pot feel fantastic. Turns out the balanced question was semi irrelevant because this thing has made my HD800 scale up hugely, plugged in single ended. It's like I'm hearing my music for the first time all over again (which of course is sacred).
Please pass my compliments to the entire Bryston team, you folks are doing really fantastic work.

Hi James,
When Ian mentions "the balanced question" is he referring to a single ended input connection to the BHA-1 precluding a balanced output to the headphones? Put another way if my input is unbalanced (e.g. tape loop out from the BP26) should I not use the balanced outputs?
-

+1. If true this this would provide more flexibility for those of us who want to use preamps or processors as the source for the BHA-1. It's difficult to find a preamp that has a fixed level balanced output. Ray Samuels and ARC are the only two I can think of.

Will do. I'll report back.
Ask, and ye shall receive. From Mike Pickett:
The output amplifiers in the BHA1 run at 14db and 20db of gain, in low and high gain modes, respectively. The position of the volume control doesn’t change this, but does change the overall gain through the BHA1.
In terms of ‘clock face position’, the points at which the BHA1 is operating at overall unity gain occur around 3:00 in low-gain mode, and 10:30 in high-gain mode.

Hi!
Regarding unity gain, does operation at unity gain benefit audio in some way?
From what I understand, operation at unity gain means the signal voltage at the output is the same as the voltage at the input so no additional current is drawn from the circuit. If my understanding is correct, then perhaps operation at unity gain means the amplifier is as linear as it can be. Would this be a logical conclusion?
If yes, then exceeding unity gain would draw more current and depeneding on the circuit quality, would result in a frequency response that is not as flat as it would be when the amplifier was operating at unity gain, right?
I have noticed that most manufacturers specify the amplifier power output in Watts and only at 1 kHz. No doubt, the amplifier is less capable when full 20 Hz - 20 kHz audio range is in question.
This is for (my) educational purposes, I have no hidden agendas so please comment if you know! :D

Hi James!
I suspected this might be true for Bryston but many other manufacturers aren't doing it. In my experience, Bryston BHA-1 is essentially as linear in it's power delivery as is possible. No matter the volume, with Sennheiser HD800 it always sounds exactly the same and never loses composure or control. It is my reference headphone amplifier and my favoirite audio component. It just seems to scale as high as the other components and never becomes a "bottleneck".
However, I'd still like to know whether my assumptions from my last post are correct.
Cheers!

Speaking only as a layman…the output of most solid state amps should be linear at all volume levels…the biggest detractor would be the requirements for the drivers in headphones or speakers…. the later being more problematic as there is a large variance in headphones from 32 to 600ohms and that is not an indicator of their efficiency with regards to current/voltage draw and therefore almost makes it impossible for a manufacturer to predict how their amp will respond with all headsets.
So while most headphones can reach adequate volume levels with most devices..a full linear audio spectrum is not achieved, take AKG’s K700 series for example.. with an input impedance of just 63 ohms and a sensitivity of 105 db it is still highly accepted in the community that without adequate amplification bass can be sadly inadequate while the rest of the audio spectrum from the midrange to the highest treble is fine. Grados are another example, while being easily powered from any amplifier, those that can supply more current always allow the Grados to sound their best even though the volume output is the same.
So without an accepted industry standard as we have with speakers, where the majority sit between a “nominal” 4 and 8 ohms and manufactures have designed their amps to adequately supply a fairly linear power output to accommodate and maintain a flat frequency response in relation to the input signal..headphone users are not that lucky..but thankfully to their relatively low power requirements usually not an issue. Nor do we need concern ourselves with power output as much… as the space between our ears and the driver is more or less uniform unlike dealing with room sizes where a larger room would be require a more powerful amp to maintain higher volumes and dynamic peaks without distortion.
Also the most problematic dilemma when designing headphones is that of the interaction of the driver output with the ear canal is never linear/flat ..so even if the output of the amp in question is perfectly flat from 20 Hz - 20 kHz at all volume levels..the signal reaching the ear drum is not unless the headphone designer takes this into consideration and to complicate things we all have differently shaped ears and ear canals playing havoc on the signal which equates into a large disparity regarding a headphone’s performance, much more so than speakers.
Having said all that Bryston amps are extremely linear at all volume levels and this includes the BHA-1, is it the “perfect” match for all headphones, maybe not but it is as close as I’ve encountered.
Some of what I said may be in contradiction to itself but these are in fact the difficulties presented to product designers and necessitates some compromises in getting a final product to market.
With regards to unity gain one would need to design the amp to power a specific headphone at a set volume as in relation to the output of the source and while a nice idea totally impractical.

This is intriguing! In your opinion, what is wiser, high-impedance or low-impedance haedphones?
I don't understand what they mean when they say low-impedance headphones are easier to drive. Surely, they can achieve a higher output at lower volume settings but that doesn't mean they are easier to drive. I have noticed that they are less consistent at different volume levels and one has to be careful with the amplifier because there is possibility of some hiss from the circuitry. I just think high-impedance should be reserved for high-end headphones.
You are right about the Grados too. They certainly benefit from capable amplification. Despite Grado's specifications, I don't find them particularly efficient and to play well at low volumes, they require a solid transistor amplifier.
Cheers!

Although technology is changing ..... a generally accepted rule of thumb ….higher impedance phones require more voltage due to their more robust but less efficient motor mechanisms, and low impedance ..current and a few like the AKG K700 series like/require both.
Prior to the proliferation of portable monitoring devises most phones were high impendence and then with the advent of the Walkman in order to reach adequate volume levels low impedance became much more popular.
The impedance of the headphone has no real bearing on sound quality when properly amped but mismatching can occur, for example I find my Sennheiser HD598s (50 ohms/ 112dBs sensitivity) sound pretty good off the computer or portable device, while my higher up HD700s (150 ohms/105dB sensitivity) sound rather mediocre, but driven off the BHA-1 both actually sound very good but the HD598s will start to distort way before the HD700s at the same volume output.
So for personal preferences comes down to the intended use, but if possible I normally gravitate to higher impedance phones.

Hi Robert!
I prefer higher impedance headphones too.
Speaking of walkman, I have the Sony WM-DC2 (amorphous head, dolby C) that sounds fantastic with AKG K240 Monitor (600 ohm / 88 dB sensitivity) but not so good with the Grado SR225i.
But would you say the high-impedance headphones are generally more resilient to mishaps and their drivers last longer?

What exactly is new to this BHA-1? The balanced outputs have been on my BHA for over 2 years ? The picture shown here is exactly like
I have it in my setup since i got it....
If you've decided to add a balanced passthrough, that would be a much welcomed improvement , and great news.
Thanks,

Hi,
Have just purchased a 'new to me' BHA-1 unit to go with my Sennheisser HD800s. Prior set up was all HiFiMan rig, including their excellent EF5 Hybrid Tube amp.
All I can say is what a revelation. While my HD800s certainly sounded wonderful with the HiFiMan EF5, they simply sing and punch and reveal so much more from the same source with the Bryston BHA-1 (source BDA-1 + Sonos service).
Thanks!
Jay
-
I thought I had read that those balanced outputs where controlled by the volume knob on the BHA-1, correct?
What Marius was asking for (I believe) was a pass-through, uncontrolled by the volume knob of the BHA-1.
So, which are the current balanced outs on the BHA-1?
I'd love to one day see a BHA-2 with a bit more power, bypass outputs, and remote control.
-
Check Grit, the current balanced outs are volume controlled by the BHA1.
Given the current lineup of Bryston amps, it would have been a very welcome feature if the BHA had bypassed outputs, enabling a fully balanced setup from the Bp26 to both headphone and speakers.
to Jay: my setup exactly, sounds stunning doesn't it? do you connect through balanced or rca? My hd800 is fed through the balanced outputs, but my BHA itself is fed from my tape out's so unbalanced. Sounds great. I liked the balanced connection to my BHA even better, but need that for my speaker setup.
Never got to try a balanced split cable (enabling the same balanced signal into the BHA and BP26 from my BDA), as opinions on that seem to vary.
A balanced passthrough on the BHA or double balanced out on the BP 26 would do miracles here. Maybe someday..
Enjoy!

Hi,
Using the RCA stock cable for the HD800 and single ended between my BDA-1 and BHA-1 and SPIF coax between my SONOS and BDA-1.
I had XLR connectors that I thought I was going to use to connect BDA-->BHA but somewhere along the line of selling off my 4BSST2 and BP26/MP2 rig earlier this year I think I threw them into one of the boxes as part of the deal.....
I also use an RCA extension cable that I bought from Grado with my HD800 so I can reach my couch, where I spent most of my listening time in a horizontal position. I think I'd have to purchase a custom balanced cable to reach the couch comfortably.
That said, the present single ended set up is so unbelievable I can't imagine a dramatic improvement.
-
BTW: the BHA-1 runs pretty warm compared to either the BP26 before it or the BDA-1. In fact the unit runs hotter than my 4BSST2 ever ran when it was driving Magnepan 3.7 at high volume.
I've read on the thread that it does run warm, but mine is warm enough that I've moved my Mac Mini off the left hand side to ensure that the BHA-1 has enough open space on the top to cool. Wonder why Bryston didn't put a vented/slotted cover on the top?
Others experience the same, i.e., left side running pretty warm?

Humm, that is counter intuitive. I get the fact that a solid top pressed against a hot component would be a better heat sink vs a slotted top (more surface area to draw heat away).
However if there is an air gap between the component and the top of the unit, wouldn't a slotted top allow heat to escape the unit more effectively, instead of keeping it trapped inside the unit?

James,
I have not complained about the heat issues with the BHA-1 because I solved it by making it the only component on a shelf with plenty of air space around it. The fact is that it does run hot and despite what the Bryston engineers say I believe the solid top is the issue. The solid top is OK on the BDP and BDA but the amplifier in the BHA is another story. Other Bryston amplifiers have a vented top as well as heat sink fins for cooling. I have owned and operated component audio systems since 1963 and the only component that I have had shut down because of heat is my current BHA-1. There seems to be a significant number of users that have brought up heat as an issue so perhaps more questions are in order.

OK I will try and get an answer from engineering. The BHA-1 is a pure Class A amplifier so it will run hot.
james
-
Not to be disputing anyone here, but from thermodynamics standpoint (in a hand-waving way), the ability of a system generating (pr accumulating) heat will be dependent on the temperature of the medium it is placed in. In other words, the surroundings. The equations are non-linear which means a raise in temperature of a few degrees C will cause unproportionally higher temperature of the system and inhibit it's convection ability.
In the case of my BHA-1, during winter, it is as cold as the air in the room. During summer, it is way hotter than the air in the room. This is due to the mentioned non-linearity.
It doesn't really help the discussion but it's interesting I think.
-
Hi Folks,
From the designer:
We have tried a vented top - with no overall improvement - the unit eventually achieves the same final temperature.
Stu Taylor
PS - if it is running too hot you can adjust the bias down a little.
More input:
Vents won't help. We tried that on the SP-2 and it made things worse instead of better. Vents these days can only be 1/16" wide, and that does not allow any airflow, it just reduces the area on the case and increases heat. The present production uses a bit less bias current, and run somewhat cooler.
CWR
-
I guess the bottom line is the unit has a thermal protection circuit and a 20 year warranty, so the concern is real but academic? I must say though that it was hot enough for me to move my MacMini off the top of the unit as much out of concern for the MacMini as the BHA-1.
Should I be worried? I guess I haven't had a piece of pure Class A kit in my inventory so maybe never realized how hot these things really run.
Thanks
Jay
-
Hi James,
ST mentioned you can adjust the bias down. How? I have seen clear instructions on the SST amplifiers and that's easy to follow. Is there similar instructions for the BHA-1? :D
Thx!
John
-
The BHA-1, even at it's highest temperature, is but mild compared to tube class-A amplifiers I have so I find it quite acceptable. An amplifier like this should be the only compoment on the shelf, preferrably on the top shelf and with nothing but air above it and as little as possible components that generate heat below it.
People usually place the amplifiers at the bottom because it is the heaviest component but that is the usually the wrong thing to do.
Cheers!

Well this is strange....when i run the amp with the gain switch set to low it runs very hot. However when I run the amp on high gain, runs downright cool?
Why would this be?

Hi Marius,
I've been pondering the BP 26/balanced BHA-1 operation dilemma as well. I'm not wiling to give up the balanced connection BP26>7B's, don't want to buy a new preamp with a second balanced out unless it is a tape loop fixed level output. I ran across a headphone amp that employs a phase splitter on board that converts a single ended signal to a balanced signal for output to the headphones. It costs $2K more than the BHA-1 but seems like a good solution when compared to swapping out the BP26 for one of the few available pramps that feature a balanced tape out. Per haps the phase splitter might be a good idea for a future BHA-x.

Sounds about right, to obtain the same volume with the low output setting the BHA-1 has to work that much harder...how hard depends on the headphones.

For a closed back… when you need to filter outside sources or to keep the music to yourself…. they offer excellent sound staging and clarity and if you can get a proper seal..prodigious base…but then again the BHA-1 will pull the best/most from any phone. :D

Hi Robert!
Those are sweet headphones! How do you find the sound in comparison to the K701 on your BHA-1?

Hi Antun
Keep in mind these are closed back but AKG have tried to offer as best they could to offer a similar performance, therefor less in your head and more comparable to an open backed headphone and with that respect they’re not bad.
Can’t do a direct comparison with K701s as they were replaced by the K712s a year ago but those have also been recently sold, but going by recent memory the K550s are better focused maybe less linear and if one can achieve a proper seal…base can be better than the K712s and the “base port mode” on the K701s. The K550s are also more detailed than both the K701/712s and therefore less forgiving of poor recordings.
Although far from perfect…overall I find them a more satisfying/fun listen, more intimate..closer but with a properly delineated sound stage…. but again the K550s are my alternative to my Sennheiser HD700s when I need some sound isolation to or from the surrounding environment. The 700s are still my preferred and IMHO a much better can.

Hi Dyna,
Did we ever discuss this switcher on AC?
I found it while looking for a passive balanced level control on their site, seems rather well built, and exactly what we're looking for?
http://www.goldpt.com/sw2x.html
Hope James/Mike will be able to post their comments on this one.
connect the BDA to the Goldpoint In, and the Goldpoint outs to the BP26 and the BHA1. All is connected fully balanced. And nothing is compromised??
Seems so much more reliable and technically more advanced than a simple XLR splitter we've seen before on AC. No signal loss, no distortion.
Cheers,
Marius
Hi Marius,
I've been pondering the BP 26/balanced BHA-1 operation dilemma as well. I'm not wiling to give up the balanced connection BP26>7B's, don't want to buy a new preamp with a second balanced out unless it is a tape loop fixed level output. I ran across a headphone amp that employs a phase splitter on board that converts a single ended signal to a balanced signal for output to the headphones. It costs $2K more than the BHA-1 but seems like a good solution when compared to swapping out the BP26 for one of the few available pramps that feature a balanced tape out. Per haps the phase splitter might be a good idea for a future BHA-x.

Hi Marius,
I PM'd Mike P. on this a month or two ago and he tells me that what comes out of the 4 pin or dual 3 pin balanced outs on the BHA-1 is fully balanced regardless of the input signal. Using the single ended fixed level tape loop out on the BP 26 to the RCA in on the BHA-1 therefore does not compromise the balanced signal to the phones. No need for a balanced splitter.
-
HI Dyna,
Thanks, but it wasn't the balanced outs I was referring to talking about compromising. I meant connecting to the Goldpoint, would the balanced signal be compromised in any way.
I understand what Mike says here, and thats how I've setup my BHA. I still find the BHA1 not having a balanced passthrough being sort of a design flaw, especially for Bryston, building these spectaculair fully balanced amps. Why not implement a balanced feed to the BHA1, it is the only unbalanced bit of signal in the chain.
And as James always points out: the extra voltage swing makes many machines sing. It certainly does with the BHA1, just try it and you'll be easily tempted. Thats why we 'need' the balanced splitter.
I only chose to hook up the BHA1 on the tape loop because I play my Bp26 more often.
So, the question holds for now, hope Mike or James wil comment.
Cheers,
Marius

I've had the Bryston BHA-1 for a week now. I've owned headphone amps such as the GS-X mk2, Taurus mkii, still own the vintage Fisher 500c and I find the BHA-1 better. This of course is subjective to personal taste and perception. In any case I stick to my guns on this opinion. Paired with Grado PS1000e and BDA-1 (some HF members reacted in horror learning I had bought this DAC) coaxed to my SACD/CD player, the sound is linear with wonderful depth. On some songs I'm able to discern background/vocals lyrics which used to be submerged even w/ the GS-X mk2 and HD800 combo (about which I was reproachfully advised to "check my sources".) What's uncanny is I still have the same sources but different headphones and HP Amp.
I won't say that I've found my "end game" knowing how much this hobby has cost me over the years but I will say that it's going to take something quite remarkable even revolutionary to better the sound I'm getting from this amp/HP combo. :thumb:
-
I wanted to poke my head in here and mention that I'm one of those nuts that runs his headphones directly off the power amp speaker taps.
I've never had the pleasure of hearing a BHA-1, but I currently have a 2B and run my speakers off the binding posts. Actually, I know there's a headphone jack in front but it has resistors in-line... so I took those out :P Interestingly, I prefer the sound of the 2B over the 3B and 4B with my Hifiman HE-6. However, the 3B and 4B that I have are quite old (pre SST era). One of these days I'd like to hear an updated model.
I just recently acquired a Stax SR-007 as well, and have been connecting those to the Brystons through a Woo Audio WEE transformer box. I modded one of the ports to bypass the transformers, but unfortunately even the 4B doesn't have enough gain to drive the 007 directly.

Hi!
I must say the difference between single-ended and balanced connection on BHA-1 is dramatic. I can hear an audible improvement in transparency and detail retrieval when BHA-1 is connected to the source with balanced cables, even when using the same source.
As it is sometimes the case, some amplifiers work better when you connect them to a source with balanced cables.
BHA-1 inverts the signal so inevitably, signal coming out of balanced outputs is balanced, despite the source or the way it is connected to the amplifier.
Cheers!

Gents,

I can't speak for the BP26 but I'd venture to say the differences are likely to be substantial. It would be dependent on the headphones. BHA-1 is a remarkable amplifier and there seems to be no limit to it's potential, no matter the source quality as it grows with the system.
-
Gents,

Hi Gibalok
Had a BP25 for years which has the identical HP output as the BP26 which is powered off the preamp output…. and while is was fine for casual listening it had trouble powering most of my phones with any authority and would get maxed out on the volume so I always had a dedicated headphone amp in the system. The BHA-1 on the other hand has been designed from the ground up as a fully balanced class A dedicated headphone amp, so all round a lot more powerful and flexible.
Currently I’m really enjoying mine powering the Audeze LCD-2s

Rob80b,
Thanks. That is what i suspected. BP26 is great pre, but will save for dedicated headphone amp :wink:

Just bought a BHA-1this weekend. The plan is to use it mainly as a preamp in combination with my 4BSST2 poweramp. My speakers are a pair of PMC OB1i.
Im very happy with the sound quality but the problem is that there seems to be too much gain in the system. I have the 4BSST2 and the BHA-1 in their respective low gain settings and Im using balanced XLR connections between them. With this setup I can only use a tiny fraction of the volume control (say between 7 to 8 o clock) before the sound is too loud. Some of the reviews of the BHA-1 also talked about such issues when using it as a preamp. Im just wondering if there are any good solutions that could help reduce gain in my system. I came accross passive in-line attenuators as one possible solution, but Im not sure of their influence on the sound.
Any help will be greatly appreciated.

Is it possible to modify BHA-1 to have higher output impedance? The 300Ohm Sennheisers and 600Ohm Beyerdynamics love that. :)

You could just build a cable/adapter with some resistors in series.

I am a very happy user of the BHA-1 with the Senn HD800s using balanced cable. Unfortunately, I sometimes get complaints from my spouse due to the noise leaking from the open headphones. To fix this I am thinking of getting a good pair of closed headphones to use when we are both in the entertainment room.
Any suggestions for models that I should look at? Will I be able to get close to the SQ that I experience with the Senns?
I have read about the Beyerdynamic DT 1770 PRO - does anyone have experience of this phone with the BHA-1?
Thanks
-
I use a Fostex TH900 closed back with my BHA-1 and think it sounds great. MrSpeakers, just released a flagship closed back called the Ether C, that looks is getting favorable reviews. If I was looking at high end closed back phones, those are the 2 I would check out.

Unfortunately, there are no closed headphones that will match the resolving power of the HD800 (for that matter, the competition is really thin in the open headphone arena as well). Just keep that in mind when shopping around for options.
Another possibility is to get your spouse some decent wireless headphones, with which to drown out the sound of yours!
-
I love my Adueze headphones, and the produced a closed for met headphone a hear or two ago. Not the sake sonic signature of the HD800's though.
-
Thanks everyone
I guess wireless headphones for my better half is the way to go.

Apologies in advance if this topic has already been covered. The BHA-1 owners manual states the recommended impedance is 32 ohms but you can use phones with impedances down to 16 ohms. I have my short list of phones down to HIFIMAN HE 1000, Audeze LCD 3 and X and Misterspeakers Ether. Of the 4 only the LCD 3 at 110 ohms comfortably exceeds the recommendation with the HE 1000 just exceeding it at 35 ohms and the Ether and X way under at around 22 ohms. I would be very happy with the LCD 3's and understand they are a good match for the BHA-1 however I also like the Ethers and especially the 1000's (which has the lowest efficiency @ 90 db.)
-What performance deficits will I experience using phones with lower than the recommended 32 ohm impedance?
-Does anybody have any experience using the Ether and HE 1000 with the BHA-1?
-When discussing low impedance vs. high impedance phones what is the cutoff point or does it vary with other variables?
Thanks!
-
Does anyone have any experience driving the HIFIMAN HE 1000 with the BHA-1? How about MrSpeakers Ether?
-
Hi, I had HE-500 balanced with the BHA-1. They required lots of power. Not so for Audeze LCD-3, Sennhiser HD800,HD650 or my Fostex th900. I know it's not HE-1000 but I hope this helps.
-
I have HE-500 with balanced cable to BHA-1. BHA-1 receives signal also via balanced cable, BHA set to low gain. I enjoy the sound very much, minor issue is with BHA having too much gain. I listen with the knob between 8 and 9 and some variation in the input gain results in not so pleasant loud sound. I fixed this by enabling ReplayGain on the player.
-
Thanks for the HE 500 feedback. It is instructive as the impedance of the 500 is close to the 1000 at 38 and 35 ohms respectively. Sensitivity is a little better at 90 db on the 1000 vs 87 db on the 500. Looks like I should look for a more powerful amp if I want to go with the HE 1000.
-
It also really depends how hot the signal coming from you dac is. A hot 2V or 4V signal from a dac is often too much for normal headphones and trimming it down before hitting the headamp can give you a little more wiggle room on the amp's pot.
-

Hi!
Power is not an issue with BHA-1 but it wouldn't be my first choice for the HE1000. IMO, an amp should only build on the strengths of the heaphone, not take the sound in a different direction. BHA-1 is exceedingly flat at any volume (linear you might say), displaying everything that's good (or wrong) with the system and the music. It simply disappears and doesn't become a variable in the mix and is as good or better than amplifier I have heard. But... in this respect, it is an ideal match for something along the lines of too-often-mentioned Sennheiser HD800 and perhaps AKG K812. But to build on the HE1000, I'd look for something like a hybrid tube-input/transistor-output amplifier like the Pathos Aurium. It would complement the less assertive and more liquid character of the HE1000 quite well.
Cheers!

Steven Stone of Home Theater Review.com says about the Bryston BHA-1 Headphone Amplifier: "Of all the headphone amplifiers I've heard and seen, the Bryston BHA-1 is the most flexible, with its two gain settings and ability to accept single-ended and balanced [both mini and standard] headphone connections.
It can also serve as an analog preamp. Along with superb flexibility, the BHA-1 also sounds excellent with a wide variety of headphones, from high-sensitivity in-ears to the Audeze LCD-2s and 600-ohm Beyer-dynamic DT-990s."

Happy new year all, may you have a safe and healthy 2016!!!
I just received my latest Bryston product a bha-1 this past Wednesday (I also have bda-2, bp25, and 4bst). While not new to headphone listening, new to this level of listening, after auditioning hd 600, 650, and audeze el8, I settle on a pair of LCD-2s. I listen to magnepan 3.7i, so I like the planner sound.
The bha-1 really brings out the sound and capabilities of the lcd-2 and I never thought I could enjoy listening to headphones as much as I do my maggie speakers. Still experimenting with connections, currently I don't have balanced connects for the lcds, so just been trying SE and balanced connects from bda-2 to bha-1. Very happy with my latest bryston product :D. One thing I noticed even after several hours of listening volume level below 9 position unit is barely warm, I read were some mentioned it got really hot.
Ps James Tanner thanks for advice on the few times we spoke, and customer service has been excellentl!

Sure they can... Just take a listen to "Popular" music !
("Stock" Senn HD800 must be "voiced" using way too much "popular music"; The good news is they can be absolutely great sounding headphone once you get rid of a few parts that are generating the silly voicing that Senn gave them) (I would bet "my" HD800 would mate quite well with a BHA-1 )

well, I hope so.
I'd rather buy a LCD-2 _ but service in an issue for me.
it's hard to get service for my HD-600 in case I needed it, despite there is an official rep of Senn here in Uruguay.
so I'm heading towards the 800s + BHA-1, soon after I finish to understand my BDP-2 (which seems to be hopefully soon, solved a number of issues simply by thinking them over).
thanks a lot for your point of view, steve.

Well ,supposedly the the HD600 has the reputation of being quite a bit more neutral sounding than the
HD800 .
They are structurally sound enough for many years of "service free" use. While they don't have the "Bells & Whistles / Wall of Sound" that the HD800 has, that sound was what I was referring to (& what "I" ended up "making changes to")
About the only "preferred" changes that people seem to do with the HD600 is changing the headphone cable
(Even just going to the cable the HD650 uses is an improvement) & using them with a good headpone amp (Like the BHA-1) . (Or I'd still go with the LCD 2 as the HD800S still appears to have the same "parts" that have to come off)
I do stand by my statement on "Popular" music if we are talking about it in terms of the general sound quality
that tends to be a "shake & bake" sonic experience way too often .

What mod? I am interested also if there is a mod allowing to lower the gain of BHA-1.
-
He might be busy/away at CES this week.
-
still no response...
-
I hope they answer you soon re: i am using my BHA-1 as a preamp and the gain using a balanced input is 10db spl higher than if I use single ended at the same volume setting (makes using it as a preamp using XLR almost a non-starter).
Have others experienced this level of difference in output?
-
Think I just answered my own question (yeah google). From an earlier post by James:
"Hi
Yes - a balanced connection has 6dB more gain than a single ended connection (because it has twice the voltage swing). So if you use a Balanced Source you get the extra 6dB of gain and if you use a balanced XLR Output from the BHA you get a further 6dB of gain for a total of 12dB.
James
PS - another advantage of Balanced is a lower noise floor as well"
-
The lower noise floor is what I have experienced with the totally balanced connection between all components (CD to pre to power) . I would never go back to single ended :thumb:
-
Thanks. Unfortunately the higher gain when connected DAC to BHA-1 via fully balanced connection makes it most unusable as a preamp.

Why so ... ??
Too much gain for a power amp input !? I don't know.
Or too much for headphones ... o.O

-
For power amp. The gain is so high with an all balanced connection the volume control barely gets past 8-9 o'clock before the volume is too much.

I was considering it as a possible upgrade from my BP 25
there are few choices where i live.
the other one might be the sennheiser hddv 800 [http://tinyurl.com/mn7suqc] - but i already have a dac, and the senn is pretty expensive.

Hi;
My apologies that you haven't received a response on this e-mail. I actually have not been able to find any record of your original request, so please send it again, or call me at the main Peterborough #.
We can reduce the gain on a BHA1 by 12db quite easily by rearranging the gain resistors, and this modification would cost 1 hour of labour, at $85.00, plus shipping.
Thanks,
Mike
-
Hi!
I have a question regarding the gain setting on the BHA-1. The standard model has a gain of 14dB and 20dB at first and second gain position respectively. Are these gain settings independent or does changing one setting inevitably infludence the other setting as well?
For example, if the gain at the first setting was changed to 0dB, would the sencond setting remain 20dB or would it now be 8dB which is the difference between the first and second setting?
Thank you!

MEMO: To All Bryston Customers
SUBJECT: Bryston BHA-1 Headphone Amplifier
April 2016
Hi James
After my previous amp developed problems for the second time, I decided to obtain an amplifier that was my favorite at the last Portland meet, cost no object (and there were some very expensive amps there), and despite the large amount of desk real estate it takes, namely the Bryston BHA-1.
(http://www.audiocircle.com/image.php?id=140728)
BRYSTON BHA-1 HEADPHONE AMPLIFIER
This is a shockingly good amplifier. It does everything well. Completely neutral. Butter smooth up to ear bleed volumes. Amazing imaging.
You rarely see it mentioned on Head-Fi, which is a big shame.
The BHA-1 Headphone amplifier is a giant killer.

The BHA-1 Headphone amplifier is a giant killer.
James, while at it I thought this might be a chance to tell what has prevented me to buy a BHA-1 sooner.
I cannot think of a good reason why its volume control is not remote controllable - I think the same potentiometer could be offered with a remote control as an optional feature .
By the way, I think the BP-26 could offer an optional LED in the volume pot to tell in low light where in the up-down attenuation it actually is. And to know where to grasp it quickly in low light conditions. Same for the BHA-1.
Fernando.

Ethernet and IR control are the only changes I'd wish for on my BHA-1. LOVE the sound!

... there are some other differences too ... single ended out, maybe. :o

The BHA-1 picture on the previous page didn't have a balance control pot, but looks like it had a 3.5mm headphone out? I've seen differences in the past with regards to the nomenclature on the faceplate. Different words in different locations in different versions.
Has there been a recent change in model design? If so, where can we see the most up to date pic?

This photo looks like one I saw of a prototype before release. I think I saw it in Canadian HiFi early on.

Hi James,
If you receive the LCD4 can you briefly comment on its performance. Not sure if you own Audeze or not but I think you may have mentioned owning a pair awhile back.
Mark
Hi Mark
Yes I have 2 versions of the Audeze but not tested the LCD4 yet - by the way Audeze purchased the BHA-1 for their demos.

I'm not James, but I have been using the LCD4 with the BHA1 for a couple of months. A very nice pairing.
I have no complaints.
-
I don't know if it was asked in here or another thread yet, but will any of the Cubed tech make it into the BHA-1?
Is such an upgrade even viable for this product?
-
I would love to have cubed-like technology in the linestages like BP17 or BP26. But the costs may outweigh the performance benefits.

What's up with the price increase on the BHA-1? Seeing MSRP listed as $1,695 all of a sudden everywhere.

Me and the BHA-1 have gone back and forth for the last 4 years. Every time I am about to get it, something else ends up happening. I was going to get it about two months ago, but ended up going for monitors and amp instead. They're still on my list though. It'd look nice with my BDP-1.

Just in... new from Germany, the HD800Ss....plugged them in..... put the BCD-1 on repeat disc, Kraftwerk of course :wink:...cranked up the BHA-1 and will let them burn in and hopefully do a thorough listening (I hope) this evening.

I would love to hear your thoughts, especially compared to the Audezes you have.

I would love to hear your thoughts, especially compared to the Audezes you have.
Two different beasts and I’ve had the original HD800s before, great cans but I never really warmed up to them…I’m hoping the “S”s are a little different and from a short listen there is more base, still that amazing sound field and layering but the LCD2.2s are my chill-out cans with their more intimate presentation, deep base and an overall enveloping organic sound.
The 800Ss are actually competing with my HD700s which I preferred over the original 800s.
But I’ll keep you up to date.
-
I think I have the exact same opinion! I tried the HD800's, and while I appreciated the detail and certainly the comfort, I just didn't love them. I tried the HD700's too, and while an improvement (for me) from the HD800's, I still just didn't stop focusing on the headphones and listen to the music. I finally got to listen to some LCD-2's and completely drifted into the music, ignoring the headphones themselves.
So, I'll be really curious to read what you think. I had several Sennheiser headphones prior to the LCD-2's, and loved them all.
-
This thread's been silent a long time....so I figure it's time to ask:
James,
Any chance of seeing a BHA-2 in the foreseeable future, maybe with the tech advances of the cubed-series input stage, to enhance headphone sound imaging and lower noise floor even more? Sort of a miniaturized version of the cubie's input stage circuitry?

Adding to the wish list, I would really like if BHA technology either evolves to a more functional pre-amp, with remote controlled volume, also better distribution of the gain from the volume (now I listen to about 8:00 and can't exceed 9:00 on the volume knob) or, why not, if there will be an option for the more expensive Bryston pre-amps to add a headphone amplifier module of the caliber of BHA...

Not sure if you know this; you can get the gain reduced inside BHA-1. I had it done at my dealer here a while ago, as I too could not go past 9 o'clock. Involves a resistor change or two.
I think putting a BHA-quality headamp inside a line preamp would increase costs tremendously, kill the sales volume of the separate BHA, and maybe even compromise performance (cross-talk noise?) of the line preamp. But hey, it doesn't hurt to ask Santa, eh? :lol: :green:

I've thought about making the resistor change too just for ergonomics. I rarely go above 9 o'clock with HD800 or LCD-3F balanced with the sensitivity switch on low.
CanadianMaestro, did you find there was any change in the sound quality? or did it just give you more range on the volume control?
Cheers, JT

Hi Folks,
No plans for a BHA 2 with remote volume control at this point. The BHA-1 was really developed as a specialised headphone amplifier able to drive anything out there but since we added the pre-out connections a lot of customers have used it as a preamp as well which spurred the comments about the need for remote control.

Thanks. That's good to know. I've owned my BHA-1 since late 2012 and still enjoy its tuneful, neutral and powerful qualities. I've learned to live with the lack of volume control range, especially with using balanced input and headphone output. For me, it's a set it and forget it, sit back and enjoy it deal 8)

http://www.audiocircle.com/index.php?topic=139680.msg1524421#msg1524421
HI
I do not think so as the input circuits on the amplifiers do not really apply to the low level gain stages on the preamps and headamps.
james

I am owner Bryston BHA-1 with MPS-2 source and I am very satisfied with the Bryston he did hit several headphones (Sennheiser HD800S, AKG - K812, Fostex TH-900, ATH-W3000ANV, Oppo PM1, Ultrasone Edition 10) all gives an amazing quality, I usually listen to low volume usually was not ten o'clock potentiometer, I usually listen to much jazz. The Bryston BHA-1 headphone controls all very well.

I'm talking for myself on this, don't know about other customers: I came to realize that the BHA-1 could be used as a preamp only since recently, when I bought my BDP2+BDA2.
I do think a headphone amplifier needs a remote control: arms length and cable length are long distances, long indeed, when you're diving into music in a low lit environment.
I would happily trade the newer pre-out connections for a remote volume control.
More: music frequently changes volume.
1- It can suddenly go up - and this is harmful.
2- Or, low volume passages (whose duration tend to be brief) need to quickly turn up the volume, so to discover beautiful detail (harmonics, whispers when musicians talk to each other, etc.)
My 2 cents ... but it's Bryston's decision.
Fernando.

Ha dreaming is Free, so keep doing it -- Bryston's not dumb to do it -- would cut into their bottom line. :lol:
The advantage of separates is power supply management (isolation) and thus noise minimization.

I would buy one of those today, if available from my dealer.
I fell in love with the BHA-1 listening to it at Audio Perfection in Minneapolis with a pair of AudioQuest NightHawks - fantastic sound. But, it's a space problem with my current desktop layout. 1st World problem, I know, but the smaller form-factor would be wonderful for me (and many other head-fi'ers, I suspect) and I would be happy with only SE in/outputs.

Has anybody tried the uber-pricey HiFiMan HE-1000 on the BHA-1? Version 1 or 2. Curious as to what the matching would be like.

I haven't heard them on the BHA-1, but... Do you already have the HE-1000? Because if not, I'd recommend the HE-Xv2 instead as better bang for the buck.

Anyone try the Focal Utopia on the BHA-1? I'm going to audition the Utopias on them one of these days. Just wanted to know if the BHA-1 is capable enough in showing off the Utopias. I'll be comparing them against the HD800.

I think BHA-1 will drive any HP with authority (except for electrostatics). You should also check out the Elear -- apparently spectacular.

Yes, I will also be auditioning the Elear along with other headphones that are available. Will be using mostly Bryston components for auditioning. The BDP I'm already fused with. The BDA and BHA-1 I have used before. I'll also try to A/B my current converter with Bryston BDA.

Hard to say ... there was an active discussion on Head-Fi.org in the AQ NightHawk thread around those cans vs. Utopia (not the Elear, if I recall correctly).
Worth reading, but someone who was listening to both sets with a Violectric V281 felt that 'Hawks were close enough in sound signature that the additional spend seemed insane (and this is a guy whose opinion I trust).
For me, and this was only listening for about an hour, I felt that the Elear + BHA-1 was a noticeable step-up from the NightHawks with the same amp (Audio Perfection had both sets on-hand and I went back and forth with familiar music for about an hour). I liked the combo, but, was more impressed with the BHA-1 than the headphones themselves, from lots of listening with the 'Hawks out of my Lehmann Rhinelander.
I almost bought the BHA-1 on the spot, but the image of my wife looking at me gave me pause... :roll: ... we are still fixing up the house and all of my money is going into construction for a while.
-
Now that Bryston has a miniature BDP, perhaps it would be neat to have a matching DAC and a headphone amp. I'd buy the amp in a heartbeat, considering the BHA-1 is quite wonderful.
Cheers!

After getting good results with HD 800 through Sonarworks calibration, might seriously consider the BHA-1 and other neutral SS amps.

What are you using so far -- tubed amp?
Right now just using them straight out of the Dangerous Music Source's built in headphone amplifier. In the past I had other headphone and amps, but sold them off because I went to speakers. Then I heard the HD 800 and figured it might be worth building a headphone rig around one.
Before Sonarworks, I thought I might try a tube to tame the high end. Although, I am not too fond of tubes. I like to leave my components ON and not worry about accidentally leaving them on for too long and damaging them. Solid state is easier to live with.

Try the Project Polaris. I have it, it's beautiful -- just a touch of tubular warmth without the tubes. Tons of power too. And adjustable gains and freq attenuation. The clear acrylic casing is amusing -- you see everything.

The Home Theater Hi-Fi review alludes to a comparison between the BHA-1 and the BP-25: "It also worked really well inserted in my studio 2 channel rig for a short stint, providing a welcome upgrade in sound over the onboard headphone jack in my own Bryston BP-25 preamplifier". Has anyone tried a systematic comparison between the BHA-1 and the HP jack from the BP25/26?
@James: Are the circuits significantly different? Are they both Class A?

Hi
Yes they are totally different circuits. The BP25/26 headphone amp is a very low power unit designed for fairly easy to drive headphones and single ended whereas the BHA-1 is a 'take no prisoner' design with balanced circuitry.

Hello,
Sorry if this has been addressed before, but there are just too many pages to go through. I have an opportunity to purchase a used/demo BHA-1 from a dealer, but I noticed that it's a very early model and looks different than the newer BHA-1. It lacks Balanced outs and the toggle switches seems to be different. I have no need to use the BHA-1 as a preamp. Is the sound-quality about par with newer models? Are there other differences I should know about? Thank you.

Hi Brinn

I have a question about the specs which I've always been a bit confused about when I look at them on the Bryston web site.
On the web site it shows this type of information at different loads.
Load @ 600 Ohms
Hi - 10.9V Out @ 001% Power 200 mW
Lo - 5.45 V Out @ 001% Power 50 mW
Lo - 2.50 V Out @ 001% Power 10 mW
Lo - 788 mV Out @ 001%¹ Power 1 mW
Is the Hi setting when the gain switch is in the high position?
Why are there three different Lo specifications? How do I know which one applies to my unit?
What difference does does it make to the numbers if I use the balanced input and balanced output?
Thanks.
-
^ here are some numbers I had on my audioblog, taken from Bryston a while back.
Power (continuous):
Max: 2 W/chan into 32 ohms @ 1% THD
Rated: 500 mW/chan into 32 ohms @ 0.005% THD
Also this:
http://bryston.com/PDF/brochures/BHA1_BROCHURE.pdf
That imo, is plenty of juice to drive anything under the sun, at a modest load.
Actual output may be even higher than stated.
Bryston should chime in here to correct or comment.

Since nobody responded to my post in July I'll respond to it myself, I have :lol: Just installed my new BHA-1 and Grado PS 2000e's and can report that after a couple hours I became addicted. My Focal Sopra 2's are getting a well deserved vacation and I'm not sure when they will return. This combo sounded fantastic right out of the box even using a garden variety Monster single ended IC from BP26 tape out > BHA-1. Unbelievable balance from top to bottom with deep refined bass and extra-cranial 3D soundstage. I had the Cardas Clear HP cable installed at the Grado factory with 4 pin balanced connector. Can't wait to get a few hundred hours on the phones and cable. Plan to try balanced connection directly from Esoteric K-05 > BHA-1 this week.

Picking up on my post just above I switched to a pair of balanced WireWorld Silver Eclipse 6's from Esoteric K-05>BHA-1 and it too took the Grado PS2000e's to another level of clarity, spaciousness and definition (and they were good to begin with). As mentioned I'm using the Cardas Clear 4 pin balanced cable from BHA>Grado. If you haven't checked out the PS2000e I highly recommend you do so if you ae in the market in the $2-4K range. They are a great match for the BHA-1.

I didn't have the opportunity to audition various cables to compare to the Clear. I just retired recently and wanted to get a top notch HP setup that would outlast me. :D The Cardas Clear seemed to me after reading a multitude of reviews to be universally accepted as one of the few best. I had it boiled down to the WireWorld Nano Silver Eclipse (all my other cables are WW) and the Moon Black Dragon. My dealer made me a deal on the Grado/BHA-1/Cardas combo that was hard to pass up. My cable is 4 m and cost about 1/4th the cost of the headphones. Another consideration was the level of headphones that are the PS2000e's I wanted to pair them with an amp and cable that would be of equal caliber.. All I can say is the setup is fabulous and I'm not looking back.

^ an award well deserved. I auditioned a BHA-1 at my local dealer and I was completely blown away by the sound, using either a set of Mr Speakers Ether Flow (open back) or an AudioQuest NightHawk. I own the NH, so I am familiar with the sound and the BHA-1 crushes my current solid state headphone amp.
I guess it should at $2K US ... still, it's at the top of my Head-Fi shopping list.

Yes (I have others, but that's my current SS amp in use).
I like it and I think it's a solid choice at $500. But at 1/4th the price of the BHA-1, you get what you pay for. Well, i should say it's easy to pay too much and hard to pay too little.

As an owner of one I believe, as does most of the audio press, that it was underpriced to start with. Relative to its current competition it is appropriately priced.

Hi Folks
Yes the BHA-1 was mis-priced when it was first introduced and the bean counters said we either raise the price or discontinue it.
The weird part is we sell more of them now then we did then?

The "high-end crowd"... they had their doubts as it was too affordable, relatively speaking, and considered too expensive for the entry level....times have since changed and now sits in the sweet spot. :thumb:
-
Speaking of the BHA-1...anyone else like to see to a an update or a possible retrofit board for the balanced headphone outputs...possibly converting the dual balanced xlrs (anyone actually use these anymore) into another 4pin XLR and the inclusion of the newly introduced 4.4 mm balanced Pentaconn (may become the new balanced standard). Looking at the layout it shouldn't be too much of a modification but it would definitely make the BHA-1 a more attractive progressive purchase for many.....Just a New Years thought!

It's a good example of how the market actually works. There's a lot of psychology behind it of course.
I remember what the owner of Audio Epilog, a small loudspeaker manufacturer from Croatia, once said. While they were selling their speakers at high prices, they sold pretty well. He wanted to make it more affordable for the customers and the sales dropped. In fact, they dropped so much that they had to increase the prices to be higher than they originally were to save the company from bankruptcy.
The point is, Audio Epilog sold their speakers because abroad they were seen as a boutiqze company from an exotic country. Even though I live in Croatia and there is nothing exotic about it to me, I know that's how North America perceives us. As soon as they decreased the prices, there was suddenly nothing 'boutique' about it and the speakers became something cheap that's not made in the US.
Luxury industry works like this all over the world. We are not talking heavy machinery, ship-building, pharmaceuticals or semiconductor industries here and you don't die if you don't have it.
-
What Rob said about the connectors is perfectly valid and I agree 100%. Bryston must remember that dual 3-pin XLR connection was an act of desperation for the early DIYers because nothing else was available. While technically there is nothing wrong with this type of connection, quite the opposite actually, it is not very practical for headphone users. What's more, if Sony is now behind the Pentacon connection type, then others will follow and more and more headphone manufacturers will implement this type of a connection. Bryston should seriously take this into consideration.
Cheers!

Looks like the BHA-1 Headphone Amp came out in 2012. There is a used BHA-1 for sale in my area that was purchased in 2013. Price for this used gear seems reasonable. Question is should i get it? Have there been any changes/improvements to the BHA-1 since 2012/2013? Any plans for a new BHA model? I am not in a rush. I would wait to buy a new one if there is reason to. Right now, I have a Violectric HPA V1 Headphone Amp (end of life). Want to try something different. I own a Bryston BDP-2 and BDA-3 and I am happy with them.
-
Were any changes made to the BHA-1 since it was introduced? Seems like a pretty steep jump in price albeit around 4 years have passed?

Early models did not have the preamp outputs at the back. Beyond that I do not believe there have been any significant changes.

...Have there been any changes/improvements to the BHA-1 since 2012/2013? Any plans for a new BHA model?
The one that i know is a volume potentiometer. At the momen in the BHA-1 features list on the site Bryston claim the use "High quality Noble stereo volume control". But my amp from 2012, some very first vertions i guess... and there Alps volume potentiometer inside. Intresting that if you google BHA-1 for inside pictures, you will find both vertions with Alps and Noble.

I am also courioius from which year they change it, what was the resason, is it sounds that better...?
-
James, have there been changes to how the volume control Works? My BHA-1 has a tailored volume control that has a fine adjustment between 9 and 15 o'clock and a rather steep adjustment below and above that. Has this been changed to a linear or logarithmic volume adjustment?
Cheers!

I can confirm my (Alps), not leanear.. its fine adjustment between 9 and 15 o'clock.
What is interesting that in photo from last mentioned here review (2017).. it also Alps inside )

Hi Antun
I am not aware of any change - if there is too much gain you can reduce the overall gain with the front panel switch. A lot depends on the efficiency of the phones and the BHA-1 was designed to drive the more difficult phones out there.
Also I think there is a modification to reduce overall gain if you want but check with Mike on that. - mpickett@bryston.com

I'm a bit late to the party. I've had my BHA-1 and Sennheiser HD800 combo since late 2012, but only just discovered what they're truly capable of.
I discussed some options with Gene at Take Five Audio and ordered some short custom balanced XLR splitter cables so I could connect my BDA-3 directly to both my BP-26 and BHA-1. I also ordered a custom balanced headphone cable with 4-pin XLR for the HD800.
Wow. I'd often read that running balanced in/out was the best, but I had no idea how improved it would be. Resolution and dynamics are vastly improved over the single-ended 1/4" connection. Like listening to 24/96 after an mp3.
I also asked Gene to make a short 4-pin to 1/4" adapter cable, so it's easy to A/B the two connections and use my new cables on other head amps.

I just picked up a pair of the new Focal Clear headphones.
These sound the closest to my Model T Sig speakers of any phones I've tried to date driven by Bryston electronics.
Focal introduced the Clear priced between their Elear and Utopia with top-notch build quality and included accessories.
I am very pleased with these on portable amps and dedicated balanced separates. They compare very favourably with my HD800. Not quite as quick or resolving, but not as dry and analytical. They have a smaller soundstage, and not quite as airy. The HD800 being a bit more suited to acoustic and classical and the Clear more of a rocker.
They have a slightly raised bottom end, yet are neutral throughout the rest of the audio spectrum. They are very easy to wear and fun to listen to for hours.

What portable amp are you using to drive the Clears?

Always had a love hate relationship with the 650…back in 2003 with AKGs and Grados in the roster the original was just too polite for my tastes…the later versions were better or it might just be the BHA-1. :D
My most recent pair was bought new last summer just after selling my Massdrop HD6XX…lol…just preferred the original look….anyway those were sold in the fall to make room for the newer 660s. Considering I sold off most of my ancillary phones after getting the HD700s in 2013 and then sold after getting the 800S I’m hope bring the 6xx with a similar driver will sound more in line with my personal preferences.
Anyway my 660s have been on backorder with Amazon since late November……but finally shipping this week, should have them Tuesday or Wednesday.…will post impressions.

Hi fellas!
I have a question for you. I have one of the earlier revisions of BHA-1, serial # in the 3xx range, which still has balanced preamp outputs.
My question is regarding the gain structure of this amplifier. I am using it with a BDA-2 DAC with balanced XLR cables and with a pair of Sennheiser HD800 headphones. They are 300 Ohm and in my opinion, very sensitive. So much in fact that I usually listen to music with the volume control around 8 - 9 o'clock and the gain switch set to LOW.
Is it possible to decrease the gain of this amplifier and would this have a negative or a positive effect on the audio quality?
If the gain is 14 dB with he switch set to LOW, I'd perhaps be interested in decreasing it to 0 dB (zero). This would put the volume control in-between the 9 - 15 o'clock range where the most precise adjustment to the volume can be made.
Thanks!

I had this gain adjust done a few years ago. Involves changing a resistor. Allowed me to use the vol knob at 10-3 o'clock, low gain in balanced.
I did not hear any decrement in SQ afterwards. If you can, I would recommend it, for headphones. Not sure about effects on preamp outputs.
My dealer made the adjustment after MP emailed him the specs and instructions.

Oh, I really think online comments with respect to HD800 being difficult to drive are way exaggerated. It is no more difficult to drive than the HD650. AKG K701 is far more demanding in reality. Unlike the Sennheiser which require a bit of voltage, AKG K701 requires current. It's a theory of mine that AKG is sort of like ATC speakers. Very flat and responsive but rather demanding of current because of flat wire voice-coils which AKG also employs in the K701.
I think what they mean by "difficult to drive" is that it is difficult to find an amplifier that matches well with it's "sound signature". Still, I don't really agree with that either. HD800 is very revealing of up-stream components so it will show any flaw. To find components that are similarly revealing is a challenge but ultimately worth the time if you value an honest approach to listening to music without "impressionism".
This modification is way too complicated for my distributor. I have had some problems with them before. If I'll be going ahead with this, it'll be done by Bryston themselves or not at all.
Cheers!

Oh no, I didn't it mean it like that. What I meant was that Hifiman is not to be found anywhere in Croatia. There's one dealer but of course, they are nothing but order takers and expect you to pay in full in advance before they even order the headphones. Seems very little sense to buy a pair of headphones you have not heard, especially with so much competition. In any case, the prices are ridiculous nonetheless. If something costs 1 dollar in the US, you can be sure it will cost 2 dollars in Croatia, even if it is a European-made product.

Foreign dealers would leave me with the same problem of not being able to listen to the equipment before purchase. Like I said, all of these nitwits are nothing but order-takers. It is surprising to me how little the manufacturers care about who's representing them because the distributor/dealer network is directly responsible for the sales. In a somewhat traditional country like Croatia dealers that have zero stuff when you walk into a room don't last more than a couple of months. If they are about to pay a premium for something, people expect quality and expect to be able to see it and hear it before they buy. This is why only pro-oriented dealers who usually sell musical instruments prosper among audiophiles. They often sell traditional brands of headphones like Sennheiser, AKG and Beyerdynamic. In fact, I am aware of only a handful of stores in Croatia where you can directly try a dozen or more headphones.
Whatever they choose to call it, it's really poverty. You'll have one hell of a time trying to sell a luxury item that ISN'T a smartphone. But sell bananas at 50% discount and you'll be packed to the roof.

Any thoughts regarding the Sennheiser HD660S?

Any thoughts regarding the Sennheiser HD660S?
The HD660 in IMHO is a fine sounding headphone and nice fresh approach to its aging 600/650 brethren which continue to hold the test of time. Performs great off the BHA-1 but no slouch off less capable amps due to its lower impedance.
So if you're a fan of the 600 series midrange but wished for clearer extended highs and better controlled base over the 600/650 then the the 660S should work quite adequately and are more engaging but having said that one may still prefer the warmer more laid back and forgiving character of the originals.

Thank you!
I have had an HD650 but was foolish enough to sell it a few years later. I got a T1 instead which proved to be unreliable. I had to send it to Beyerdynamic twice only to eventually sell it as non-working. At that point I had already sold the HD650 and realized how big of a mistake it was.
I liked the HD650 but at times wished it had more detail in the treble. HD660S would perhaps be more suited for my taste.
Cheers!

I’ve owned 2 pairs of HD650s and the Massdrop HD6xx, not to mention the HD580/600s....even though they covered most of the bases they all left me disinterested no matter how hard I tried to accommodate them. So for my own personal preferences the HD660S were for me a breath of fresh air but then I was also a fan of the HD700s.

Hi Rob!
Can you please tell me more about the differences between HD660S and HD700?

I think it can be generally agreed upon that the 660S to many, not all, is a refreshing face lift to the 600/650 by maintaining the cherished mid-range but producing better extended clearer highs and quicker better defined bass. The HD700 is quite different IMHO and a nice departure from the 600 series sound signature, not quite the 800 but it produced a fairly extended sound stage, deeper and better extended bass over the HD6XXs, the recessed mid-range put some off but that was what made the 700s more speaker like. Also IMHO I've come to believe that if the 700s were not powered properly it resulted in some complaining bitterly about its extended highs, ...which were never a problem off the Bryston BCD-1/BHA-1 combo, of which I believe actually added to the realism and excitement of the recording. :thumb:

Okay, so in your experience, does HD700 have more bass than HD660S?
I never heard an HD660S or an HD700. I have an HD800 (non-S model) which I bought in early 2012 so this is my only reference. On the BHA-1/BDA-2 the HD800 shines and providing the recording is adequately high-quality, there is no sibilance.

Didn't compare them side by side and as you know rumor has it they share a similar driver and going from memory the bass was similar.... but the rest of the frequency spectrum was quite different due to the fact that the ear cup and baffle design is very different between the two....
The angled drivers in the 700s have a tendency to direct the treble energy in a unique way which produces a wider sound stage but this I believe is what is responsible for some head-fiers perceiving the upper frequencies as unwanted annoying treble peaks. Personally I believe the Bryston combo of the BCD-1 and BHA-1 kept things under control so it was never an issue. :thumb:

Hi Rob!
Yes, I too have read the drive units between the two are similar. It just goes to show there's more to acoustics than "plain" drive unit design. Hmm, I will need to think about this.
When I had the HD650, I liked it very much. However, the one thing I always missed was a bit of detail in the top end as it always seemed to mask some of the fine harmonics of acoustic instruments like piano and violin. All of that has been corrected with the HD800 but they take serious umbrage if you feed them substandard recordings. However, I never found HD650's sound stage to be too small. It wasn't particularly wide or deep but it was adequate I think. Perhaps HD660S would be a better choice for me than the HD700 because it seems to improve on the one thing I missed with the HD650 - top end detail.
Still, I think anyone can agree that HD700 looks simply spectacular.
Like I said, I will need to think about which one to buy.
Cheers!

If you do have the 800s already I'd personally swing for the 660S if you're in need of a second can to cover the bases. The 700s are closer to the the 800s so you'll always be reaching for the 800s and the 660S are much kinder than either 2 for substandard recordings while maintaining a similar frequency clarity of the 700s.
-
For classical or instrumental jazz, well recorded, I totally get the comments about clarity and sound stage.
But I have a collection of original issue and re-issued LPs of vocal-centric music from the '50s & '60s (e.g. Frank, Dean, Barbra); the 650s kill it with this genre of music, with the right amp. For me, it highlights the difference in genre coverage, between the HD-650 and the HD-700/800 (I've not listen to the 800S).

Check my thread here.....
https://www.audiocircle.com/index.php?topic=121595.0
and here....
Just to see is if the above mentioned attributes transfer over to using the BHA-1 as a preamp I managed to hook it up front and put it through its paces.
Basically your purist set-up, BCD-1, BHA-1, 4BSST and the Dynaudio Special 25s.
(http://www.audiocircle.com/image.php?id=90190)
In a nut shell I heard the best reproduction of cymbals that I’ve had the pleasure of hearing, definitely one up on my previous BP25P which was true to its numbers but which I have to confess I felt was getting a little long in tooth and was replaced by the very affordable Emotiva USP-1 this year to accommodate HT bypass with sub woofer management, but only because the EMO IMHO did sound better even with the phono, sad to say. :(
Needless, I was losing faith in my coveted Bryston, but the BHA-1 in its minimalist approach has brought a whole new sound to the playing field, the word that comes to mind is “Crystal Clear”.
My biggest caveat with the BP25P, at least in system, was the lack of distinct layering and depth with the Dynaudio Special 25s, the USP-1 resolved and that and was what made me question the BP25s resolving power.
The BHA-1s imaging prowess IMHO, at least from what I’ve heard so far is second to none; width, layering and depth is very distinct, with no doubling up, the full audio spectrum appears to have better resolve top to bottom.
As I mentioned cymbals took on a new vitality, they were distinctively real when listening to John Surman’s “Stranger Than Fiction”, very silky but not in the bright sort of way, just right, the same being said for the piano and Surmans sax, the drums displaying that tactile feel.
Just to change pace I threw on some Techno, Underworld’s “second toughest in the infants” expecting the clarity of the BHA-1 would have be reaching the volume knob, which was not to be, sat down and listened again through the whole album. The bass was extremely well resolute and again with the resolving power of the BHA-1 the music was a pleasure to listen to.
So once more as with the SST series, the BCD-1 and now the BHA-1 Bryston continues to show what can be done, thanks guys! :thumb:
Too bad there’s no HT pass through, remote and bass management, other wise the BHA-1 would stay right up front, plus the silver doesn’t match the rest of my equipment. :scratch:
Maybe there’s a BP30 in the works! :)
-
I’ve used the BHA as my preamp in an all Bryston electronics set up (bdp-1, bda-1, 7bsst2) for several years. It is an excellent preamp. I have had the gain reduced as I have very efficient speakers.
If it provides the flexibility with connections that you need and you can live without a remote then it provides a great low cost minimal solution.

Not to speak for James...no downsides audio-wise IMHO but you'll need to shut down the connected amp when using headphones as it does not mute the rear balanced outputs ...... also, and I've talked to Mike about this one, but the BHA-1 has a remote trigger in but no trigger out :scratch:...would have been nice when using it as a pre to power up and down the associated amp.

Hi
The BHA was never designed as a preamplifier - it was an afterthought so the first 50 units did not even have a pair of Balanced outs on the rear.
We realized we could add the extra outputs and that allowed a bit more flexibility for those that wanted to use it as a preamp.

hi james
i noticed the BHA user manual doesn't show balanced output on the rear side. Now i know why. cool.
i had a look at the input impedance specs of the BP20 (15k ohms) and the BHA1 (10k ohms). Used as a preamp, and everything else being equal (power amp, cables, etc), would the lower impedance of the BHA have any effect on sound compared the BP20 - other than volume control?
-
^ it shouldn't.
It is a good thing for a voltage input, as if the input impedance is high compared to the source impedance then the voltage level will not drop too much due to the divider effect.
generally an input impedance of at least 10 times the source impedance is a good idea to prevent significant loading.
-
I am using BHA-1 mostly as headphone amplifier with BDA-2 and BDP-2 and this is the first time when I am not thinking about upgrading anything, anything whatsoever. My HD800S and Hifiman HE1000v2 with Bryston stack sound exactly as I like it.
I have two questions somewhat related:
I cannot figure out the BHA-1 volume control. It is a steep increase in volume, then a flat part and again increase in volume at the lats part of the turn. Is this a way it is supposed to work?
And the second question regarding the preamp function. I found recently a very good price on two 2B LP Pro and decided to bridge them. This is the first Bryston amp I have ever tried, both are more than 25 years old, and they are way better than my Emotiva XPA- which I sold promptly. But With the 2B LP gain at 3 I have to run two Shure XLR attenuators at -15dB to get the preamp volume to even 10, it is loud, nut the sound is the best.
I am running 6 Ohm speaker in bridged setup which is the way it is supposed to be, and it is temporary, but I listen mostly to classical music at low volumes. Basic question is: in this imperfect situation how should I set the 2B gain? High with attenuators, or much lower without?
-

Since you stated that you listen at low vol, then set the 2B gain to a lower setting, without attenuators. Then use the preamp vol knob to a fuller extent.

You can try what CM suggested and I do use it that way if I use the 2BLP pro has a head-amp as there is way too much gain otherwise.... but for speakers IMHO I've found it best to open up the attenuators completely on the 2BLP pro as the potentiometer on the BHA-1 is of a higher quality and one is not constantly fiddling to get the balance right between the two channels...experimenting is free though :D
Also if I'm not mistaken when used as a preamp the BHA-1 performs normally and is more linear in terms of adjusting the volume from quiet to loud.
...but I'm a bit perplexed that even with the -15 attenuators (they are directional) it is still too loud....hhhmmmm :scratch:
-
Thanks, it is helpful. With -15dB is not too loud, it is just right with 2B LP gain fully open and BHA-1 at app 11.
But my understanding is that there is not much of a difference between inline attenuators on the input to power amp, and reducing the gain on the power amp, but I am not sure about that.
It could help to know the BHA-1 voltage on balanced, outputs and what is acceptable input range for 2B LP but I cannot find this info anywhere

Try it and let your ears determine whether there's a difference.
I'm confident the 2B can handle the bal out voltage of BHA-1 preamp. But Bryston should chime in here....

Think of an in line attenuator as a fixed single "stepped attenuator" using stepped resistors, they're highly coveted but expensive but are way more precise and less prone to failure than a variable potentiometer.
So yes it would be better IMHO to have at least one of the components fully open, in this case the 2B and use the -15 attenuator to reduce its input as I explained earlier.
(https://www.audiocircle.com/image.php?id=181315)
Both the BHA-1 and 2B are fairly robust and will handle almost any input, if I'm not mistaken.
2BLP specs
Input sensitivity: .775v for 60W @ 8Ω
Input impedance: 50KΩ unbalanced 10KΩ balanced

Thank you
I was thinking in line Shure attenuator. To keep the 2B LP gain fully open I would have Shure set to - 15dB between 2B LP and BHA-1 and then I will have have some room on the bha-1 volume control. Otherwise it gets very loud when volume knob at 9

Given that headphones are now hotter than they have ever been and the BHA-1 is about five years old, what is the likelihood that we will be seeing a BHA-2 in the near future (on a probability scale of 0-1)?

Hi
No plans there. Unless we see a way to build a better version of a piece of gear we have now we do not just build a new version to call it 'new' without a measurable performance advantage.

A very "sound" policy that helps to engender the loyalty that Bryston owners share.
I take it then that recent developments, including the Salomie Circuit, are not relevant to the design of a headphone amplifier?
-
Can't speak for James but a while back I proposed a minor facelift by eliminating the rarely used dual 3 pin XLRs (one can buy an adapter if need be) and implementing another 4 pin XLR (the most widely used) but with an independent attenuator...facilitating the simultaneous use of two balanced pairs of different impedance and efficiency.

In another thread there were some murmurings of a new dac/preamp combo unit with built in headamp. All in the theory stage at the moment though, as far as I know.

Good idea, but Bryston can't build one -- for engineering reasons (independent vol controls are problematic with present circuit). Understandable.

I can recommend a "great" headphone that is a wonderful match for the BHA-1. The Grado PS2000e. I've had the combo for about 9 months now and have no desire to hear anything else. Great soundstage and imaging, tremendous bass both mid and extended and a uniform frequency response from top to bottom devoid of the U shaped response of many competitors. Mine is connected balanced end to end starting withe the Esoteric K-05 onto the fixed balanced out from my Esoteric F-05 integrated amp using WireWorld Silver Eclipse 6 IC's to the BHA-1 then 4 pin balanced Cardas Clear HP cable to the phones.

Those look like nice setups, guys! I went to AXPONA this year and though it wasn't my focus during this visit, I remember literally dozens of places where you could sit down and listen to 'phones and 'phone amps. I think next year I will make that more a focus of my visit before breaking the bank on any real expensive pair of 'phones. In the meantime, yesterday I bought a pair of Focal Elears at a significant discount based on pretty positive reviews I had seen, to tide me over until I take a more reasoned (and more expensive!) next step. Happy Listening!

As mentioned above I am a headphone neophyte but received my BHA-1 Friday and Focal Elears Saturday and enjoying this first taste very much.

Some people may argue that keeping the balanced L and R completely separate will produce the cleanest signal. There's maybe a touch of merit to that, but it's going to be so ridiculously miniscule that you'll never notice.
-

Agreed. That's why when I decided to upgrade from the Grado factory supplied cable with the Cardas Clear I opted for the 4 pin connector thinking the convenience would outweigh any practically undiscernable difference.

Can the BHA-1 handle 10v input?
Maybe one for James. I have the Aries Cerat Kassandra DAC and it has a tube gain stage with 10v SE on the RCA outs. Can the amp handle that without issues? If the pot is on the input no problem. I am not sure so why I am asking.

I currently use the little Metrum Aurix on low gain (unity) with my LCD4s and have loud listening at 2 o'clock. I am thinking the Bryston will sound better of it can handle the input. :o

Well, you could make it smaller (less wide). Maybe something to match the BDP-Pi with fewer connection options.
For example, you could add/remove connections to match newer gear (e.g. what appears to be a universal new 'phones connector: 4mm balanced).

Hi Krutsch
Yes but when you look at the smaller chassis size and a few less inputs it really does not add up to much at the end cost, but I agree different features makes sense but performance would be the same.

Understood.
If you look at Head-Fi.org and look at the "show me your head-fi station" threads, you will see many examples of space-constrained setups (as well as many that are rack/shelf mounted and not constrained). Most headphone amps have more of a "shoebox" aspect ratio, as opposed to a traditional hi-fi component layout.
A little cost shaving and a smaller chassis size might translate to more sales. Just food for thought:

Does Bryston recommend leaving the BHA-1 on 24/7?
What are the BHA-1 owners doing?
-
I just got mine in the last two weeks and not that I'm "doing it right", but especially during the summer I'm just turning it on a bit before I intend to listen, as left on constantly it gets quite hot, which I wouldn't think does the electronics inside any favors.
-

The beauty of solid-state is that the circuits are instant gratification :thumb:
Unlike tube gear.
I never leave anything on 24/7.
cheers
-
Unless you're the type who believes in warmup/thermal equilibrium/etc, in which case tubes arguably reach that point sooner than solid state.
-
I meant for the longevity of the amp. I currently use my desktop rig periodically throughout day or night whenever I'm there in chunks. For the desktop speaker amplifier, with Class D, I just leave it on 24/7. Doesn't get warm or consume much. For the amp it might be better for it to be left on rather than turned on and off multiple times throughout the day.
I was wondering if the same applied to the BHA-1. If you use it 3-4 times in a day for say 30 mins to an hour with many hours in between, is it better for it to be left on throughout or should I turn it on and off every time. I'm not concerned about the SQ but rather what's the least harmful for the amp.
I also don't stack my components, plus the BHA-1 would have its own top shelf so nothing above to block any heat.
So turn it on/off throughout the day or leave it on?
James?
-
It gets warm even when idle. Like a BDP-2.
Heat 24/7 is never good for any circuit. IMO.
But why don't you just try it, and report back. Instead of asking others. Nothing like direct experience, mate.
[You could always use tubed amps. They make great area heaters for those who don't have central heating. :lol:

I don't have the BHA-1...yet :D
I'm not that much into headphones as I was, so I put the BHA-1 on hold for other things. I feel locked in with my desktop speaker/amp, and my current Audeze headphones. Haven't felt like changing or upgrading. I'd only be adding the BHA-1 with Audeze's in mind. It's good to know in advance of how a device can and should be handled. That was one of the selling points of buying my current Class D. I can treat it like a source component.
I'll wait for James or someone else from Bryston to comment. :popcorn:
-
As you don't have a BHA-1 yet, I can tell you as a new owner that mine runs warmer than any other piece of equipment I own when I listen to it/leave it on for several hours straight. It runs hotter steady-state than my 28B3 amps. As was said above, I decided that 24/7 this was not a good thing so turn it off between listening sessions, possibly at the price of some sound quality, but I decided this was a better tradeoff.
-
Hi Folks
The BHA runs pure Class A so it will run hot. The whole chassis is a heatsinc so it will feel warmer than usual.
There is no issue leaving it on - we have some in Studios which have been on for years.
James
-
On the question of giving up some sound quality by turning the unit off, I would not expect the heating up of the case to be a requirement for top performance. As for longevity, there is the 20 year warranty together with the fact that Bryston repairs very old products as a service and not a revenue stream. (I say this from experience, BTW.) I therefore don't worry about mine baking itself even though it is definitely hot after several hours. (This is saying something because I'll normally use any excuse to worry about my equipment's health!)

Thanks for the response James. It's good to know that the option of leaving it on 24/7 is indeed possible with the BHA-1.
Having said that, as described by my usage above of periodic use throughout the day, what you personally do with the BHA-1? I am not asking about SQ, but rather only interested in increasing the longevity of the amp. What would be better, turning it on/off multiple times each day or leaving it on 24/7? I'm not sure which one's the case with the BHA-1 in particular.
Will try to maximize the 20 years. Thank you.

I am having problems with BHA-1 volume control and sensitive headphones, even on low gain. I cannot run Beyerdynamic T5p.2 at all, I have to set the volume so low that it does not go beyond the point of channel imbalance and it is loud. T5p.2 are crazy sensitive but what about HD800S - cannot move the knob beyond 9:30, with HEKv2 and some classical tracks 11 is too loud.
I also used BHA-1 as a preamp to two bridged 2B LP amps. To set a BHA-1 volume to a 12 I had to set gain on both amps to roughly 50%. I am thinking about using in line attenuators between Bryston BDA-2 and BHA-1. 10dB balanced attenuators should do it, I think. I have Shure switched attenuators, tried -15dB but I am not sure how they affect the SQ. Or maybe iMatch is a better option.
Can anyone help please?
-
The gain on the BHA can be reduced by I think 6db. Suggest you contact Bryston support to get details on this.
-
I had exactly the same issue with a BHA-1 having excessive gain on my setup so that the lowest setting was too loud on most CDs. The adjustment is very quick and easy to make as well as being easily reversed if your needs change. I can't provide any more information than that because I live near Peterborough so I can simply visit the factory to have these things done. I suggest getting in touch with them to discuss sorting this out for you. I know they want it to work for you regardless of your choice of headphones.
Having your gain controls on the 2BLP amps at 50% is not something I would regard as a problem. You are using them as they were intended and they are not "supposed" to be in any particular normal position.
-
FWIW, I have been using my BHA-1 for almost a year now. It is connected to the fixed balanced out from an Esoteric F-05 integrated amp then 4 pin balanced out via the Cardas Clear HP cable to Grado PS2000e headphones. I have left it on for several days at times. It got a little warm but never hot. Also I do not experience the volume issues mentioned by several users. Average position is between 10:00 and 12:00 for almost all recordings CD/SACD or vinyl. I don't find the need for a warm up period to achieve peak performance like I do with the Esoteric amp and previously with 7B SST2's. As such I don't leave it on 24/7. This is a fantastic headphone amp.
.
-
Thank you, I am considering the gain reduction mod but in the meantime I added -10dB Rothwell XLR attenuators between the BDA-2 DAC and BHA-1. And it is working pretty well.
The BHA-1 excessive gain became even more apparent when I replaced the pair of 2B LP PROs with 4B SSTC. Even with BHA1 on Low gain and 4B SSTC sensitivity set to 2V, that what I assume should be for balanced connections, I could not move the BHA-1 volume knob past 9:3- or 10. After a couple of hours of listening the attenuators do not seem to have any bad effects on SQ, the bass seems actually more pronounced and better controlled, which is probably because now I can actually use the BHA-1 excellent volume control to find a sweet spot for listening to different tracks.
-
Hi James!
When I turn on my BHA-1, it produces a very faint "pop" through the headphones. My particular amplifier was manufactured in 2013 and was one of the first samples in Europe to have the balanced preamp outputs on the back so I assume it is the one with original 14dB/20dB gain specification. Is this normal?

Hi John, could yo share which cable you use and where I can get it? I (as many of us) have problem with gain of my beloved BHA-1. It's just too sensitive some times.
I really need to do this mode -6db.. to decrease gain. Seem a top secret mode, a lot talkin but nobody giving any details. Could we just figure-out form scheme which resistors and where need to be changed to decrease gain. It's annoying issue for BHA-1 design. With my new Yggdrasil DAC form Sciit, i can't go more then 8 o'clook with balanced connection. Going up, it no linear anymore and distorted. Mids comes to loud and bass recessed (
I am willing to do this soldering to try ant report back. But need to know what to change in circuit. It so sucks to not use this grate amp potential (

Thank you, while I wait for reply regarding gain decrease, I'd like to ask for some opinion.
The story strats after I am no happy how my new Yggdrasil DAC sounds with Brystone connected with balance XLR.
When it's unbalance RCA connection all is fine, but trough balanced interface, it somehow distorted. I hear strong mids while bass lack extention. And what is worst it's not scale with volume... with more gain, bass remains low and mids just go very loud and not pleasant. Some sort of non linearity is there. Like low spectrum truncated somehow.
While digging, i found out "interesting" balanced output realization in Yggdrasil. For some reason Earth (Pin 1) shorted with Negative signal (Pin 3). I heard sometimes it's used in consumable (not pro) level to avoid some issue. So my guess, maybe Bryston as fully balanced just don't like this type of interface. Maybe somebody could help me. I though maybe disconnect Pin 1 inside one of the cable connector to avoid it spoil Brystne circuity? Any advice?
thx

Have you tried using the BHA-1 balanced input with some other source? Input stage of an amplifier can overload with a high voltage signal. However, I checked the Schiit website and it states a maximum output of 4 V for the Iggy, therefore the same as a Bryston BDA-2 so this shouldn't be an issue.

Yes I did.. Bryston BDA-1, Hugo TT, Gustrad x20, all balanced connected with Bryston and all good!
This Bryston "allergy" to Schiit Yggdrasil is very interesting to understand and eventually resolve.
Seems it somehow bryston amp too sensitive to yggdrasil form balanced input. Strangely not by voltage (it is not higher then other DACs, i measured, it's 4,22 to be precise), but something like resistance/current intolerance between them?
What is interpreting, if I still use balanced interface between Bryston and Yggy BUT use single ended output for headphones instead of balanced output... all sound perfect again. As i understand in this case Bryston will use just half of its power..
I am going to try -10dB attenuators for XLR connection and see if it may help. But really looking for the way to decrease Bryston gain.
From other comments I've seen some other amps often implement attenuation select for balanced input. Apparently briston do need it as well to be more friendly and universal.
Any help how to decrease Bryston gain is vert welcome. I have 2 Bryston amps, and want to modify one to be less powerful! please help.
.. and considering i have this non linearity strongly in low spectrum. It like bass depression. This seem like sort of overload at some stage.
UPDATE
Get reply form Bryston about eventual mod.
The mod can reduces overall gain by around 12db in both modes (High and Low), leaving around 2 db and 8 db of gain.
For details you need to contact Bryston support directly.
XLR in line attenuators -10dB arrived.. balanced output improved a bit, but still single ended output is much better when yggdrassil connected to Bryston via balanced XLR.

Okay. If BHA-1 has no problems with overload which can manifest itself as distortion with other DACs in your collection, then all should be well with it. Your Schiit DAC is likely the problem then. Either due to non-standard pin arrangement on it's XLR connectors or due to a failure or manufacturing fault in it's circuit. How does your Iggy work with other equipment through it's balanced output? Also, be sure to test your cables with other equipment and make sure they do not cause any issues.

I brought home a BHA-1 to try out today. I also have a Yggy and i didn't hsve any problems connecting it with the BHA-1 -- it sounded great. Like others, the issue i ran into was the gain as a preamp - could barely move the volume control before exceeding my normal listening levels.
Will be investigating the lower gain option!

got my black, low-gain bha-1 a couple of weeks ago. it's wonderful -- my system has never sounded better.
with the low gain option and the gain switch on high, everything works great. as a pre-amp, the comfortable volume range is now 9-11 o'clock. as a headphone amp with hd600s, comfortable volume range is now around 10-11.
highly recommend this option for those exploring the bha-1 as a pre-amp.

Hi!
Can you choose a custom value of gain and are the low and high gain settings independent of dependent of each other?

no -- you can order a low gain version (no option on the amount of gain) which is applied universally, lowering the gain on both switch positions

MEMO: To All Bryston Customers
SUBJECT: Bryston BHA-1 Headphone Amp Review
January 2010
Hi Folks,
Ok so I got my Bryston BHA-1Fheadphone amplifier.
OK so what it does it sound like?
Without a lot of talk on base, mids and uppers. This biggest impression is the sound stage is huge.
My source is an Astell&Kern SP 2000 Copper. Headphones are HD800s
1st test was the AK powering the 800s directly via black dragon cables. The cables use the 2.5 balanced connection on the AK. They are 48” cables. Sound is great and impressive. No issues here.
2nd test the BHA-1F entered the pictured. I connected the AK to the BHA via an Astell&Kern PEF21 cable. This is a balanced connection at the AK and terminates in XLR’s to the Bryston. The factory single ended cable was used to connect the HD800s to the Bryston. AK was put in line out mode leaving the Bryston to manage the volume.
Using the same source track the sound difference is significant. With test 1 the music was coming from the headphones, its good don’t get me wrong, but in test 2 the sound felt like it was coming from some magical spot that existed 8 inches outside of the head phones and all around my head. 30 seconds of listening and yes done. She is a keeper. That’s all you need for demo time with this unit. Less than a minute.
I have since added Dual 3pin silver dragons for the HD800S (these add another 2 inches to the 8 inch sound stage described above) and a very expensive focal headphone stand. The stand is totally gorgeous and matches my setup.

Anyone listen to the LCD-2C out of the BHA-1?
I started with the LCD-2 then moved to the LCD-x and now I have the LCD-4. I used my BHA-1 with each set and they all sounded really great (I have a BDA-2, and Bryston CD player too), LCD-4s are really amazing but need lots of power and the BHA-1 delivers, the LCD-4s require the volume knob to be around 12-1 position.
-
Can you use an attentuator to being down the gain without affecting the sound quality in the BPA?

Hi Guys,
I have just got the Abyss AB-1266's in here which are the first pair of headphones that I have experienced with single balanced left + right inputs, needless to say the first thing I did was plug them into the BHA-1, yet again the BHA-1 delivered, I have tried them on a couple of other amps but at the moment the Abyss + BHA-1 is a winning combo and pretty much the best headphone rig I have ever heard :thumb:
(http://i474.photobucket.com/albums/rr109/Mikawen/Headphones/DSCF7444_zps37e11118.jpg) (http://s474.photobucket.com/user/Mikawen/media/Headphones/DSCF7444_zps37e11118.jpg.html)
Hi all, I have just ordered the Abyss 1266 TC cans to go with my LCD 4s and Meze Empys, and of course I will be running the Abyss through the bha1. I quoted this poster as the bha1 has the ability to drive the Abyss which I'm assuming? It's my end game headphone amp so I dont want to have to be buying another amp for these things. Thanks
-
I live in an interior town home, so after about 9:00 pm, if I want to listen to music, quality headphones are the answer.
I was getting so-so results from plugging into the preamp, so I bought the BHA-1. Problem Solved!!
IMO, the BHA-p1 is a headphone-listener's dream. More than enough power to drive any set of cans (other than the electromagnetic) provides for both unbalances and XLR-type outlets.
Currently using Sennheiser HD 660S cans, but plan to "trade up."
-
I am likely going to buy a Bryston BHA-1 tomorrow from Canada. This will be for a bedroom that has no equipment yet. I will need a DAC and I have a streamer. I was wondering if the BHA-1 can drive an amp such as the Bryston 3B-SST3? I am thinking of putting my KEF LS50's in this room too. Though I would need some sort of preamp or DAC with volume to drive the amp. I am hoping the BHA-1 can do the same to negate the need for a preamp. I am only going to be doing digital streaming on this system.
BTW - just an FYI to Bryston personal, the new web site is not working properly to find anything related to the BHA-1. I had to go to the old web site url.
https://bryston.com/specialty/ (this one is not good)
http://old.bryston.com/products/power_amps/BHA-1.html (this one works to find the manual)

I spent a little bit of time reading this thread.
So what I see is the following:
1) Newer units have XLR output (the one I am looking at is 3 years old)
2) The BHA-1 can be used as a preamp. However, #3
3) This was a quote on this thread. "For power amp. The gain is so high with an all balanced connection the volume control barely gets past 8-9 o'clock before the volume is too much."
- The resister mod to reduce the gain by 12 db is recommended to get greater range of volume. Cost is $85 to send to Bryston factory in Peterborough.
If this is all correct?
Mr James Tanner,
Would I be able to have this mod done and then have the unit shipped to my home in the USA? I am getting my sister in Toronto to buy the used unit from Canada.

This is used unit that was purchased from a dealer in Montreal, Quebec. I will have the receipt.
-
I never heard back concerning the abyss 1266 tcs. I ordered a second bha1 through simcoe audio a couple weeks back so I'm hoping they will be sufficient. The bha1 sounds great with my clears, empys, lcd 4, hd600s, sony z1r, and lcd xc btw. James, could you tell me if the bha1 has enough juice for the 1266s please.
-
@dmdm While my BHA-1 is getting the mods done at the Bryston factory. I was wondering how to set this unit up. Do you have it plugged in directly to a wall socket or some power conditioner?
-
I have it plugged into a Richard Gray 600s power conditioner with the bda3.
-
So no one seems to reply to this dead thread, but I'll give it a shot. I have 2 bha1 amps. One I received today and one from 2017. The first has a lot lower gain than the new one. The volume is pretty much static from 10 to 2 and I need to crank it to 3 o'clock on low gain for similar volume on the new one at its 10 o'clock on low gain. Also, the new one's volume is progressively louder throughout the dial. The older one is driven by a benchmark dac3b and the new one a bda3. The benchmark jumpers are at 0 gain. Any thoughts?
-
The volume control on my unit also is stuck at a very low position since it gets way too loud as I turn it up. I am around 10 O'clock position, not happy about that, but not a deal breaker.
Byrston BHA-1 Serial # 1334
I used XLR cable and I am testing this out at the moment with a Benchmark DAC3B.
I am actually doing a shootout with the Benchmark HPA4.
-
No you misunderstand, I like the volume of the new one. How do I get the older one louder like the new one?
-
Maybe we should trade units :D
-
I guess I just have to have the volume at 90 percent on the older one and I'm assuming this wont hurt the amp.
-
Question for James, can a black faceplate be purchased to replace the silver ?? if so whom do I call and how much is it and should I send it in for replacement ? the model was manufacturer in 2015.

Lately the volume knob sometimes is noisy as there is crackling from the speakers or headphones connected to it.
Is there anything I can do myself to try and resolve this without having to send it in?
Also if I turn the volume knob up and down a few times it eventually stops being noisy, but then if I don't use it for a couple of days or so, it does it again.
Thanks,

Hi Samjay!
You might try removing the pot from the shaft (there is only one screw that holds it in place) and use a very small amount of WD-40 or some specialized agent for electrical contact rejuvenation. I found this to be the case with my BHA-1 which is a very early S/N unit. Lots of things can contribute to this and in my case, it is extremely high humditiy where I live. 97% relative humidity at +40C can't be a good thing for anyone or anything, can it?
Most conventional volume potentiometers are like this and they require frequent use and in some cases, periodic maintenance.
Cheers,
Antun

Don't use plain old WD-40 it will gum up the area later on. Use something like WD-40 Specialist Electrical Contact Cleaner or DeoxIT

There are several other electrical component specific cleaners. There's almost always a better more application specific choice than WD40.
-
No you misunderstand, I like the volume of the new one. How do I get the older one louder like the new one?
Assuming you have swapped the two units and made sure that the input levels of the sources are not involved, you can contact Bryston to have the earlier device's gain raised. This sort of adjustment is routine because of so many headphones with greatly varying characteristics on the market. There will be some people, me included, who end up with a very high output level with only a tiny rotation of the volume knob, making it difficult to set the desired level accurately. In these cases, the gain is decreased with some minor internal change.
-
Had that exact problem (Audeze headphones). Sent it in and had it adjusted. Works great now.

Thanks! I can't get the volume knob off. I can't even open the cover. Looks like they are those Torx screws. I have those screwdrivers. I tried a T7 and T9 but they are so tight. I can't even budge them.
Afraid I'm going to strip the screws.
-
Well, I got a better screw driver and did manage to take the cover off. But I don't see how to take the volume knob off.
I know the knob has a hole in it but I can't tell what fits in it and if you can loosen it that way.

WD-40 is essentially a cleaner, petroleum distillate to be precise, I believe. It has no significant lubrication properties and should used only on pots you don't care about simply because it was not made to avoid damaging resistor rings. You would be gambling, or experimenting, if you want to put it that way. Don't do it. Bryston will help you so start there.

I've been told WD stands for Water Displacement (formula 40). Not sure if that's true or not, but it makes sense.
And agreed. Please send your equip to Bryston. They have all the equipment and expertise to guarntee you get it back as good as new.

- Garrett
That is correct and the 40 is a reference to the number of formulas that they tried before finding the one that had the characteristics they wanted. It's a good product for some types of cleaning but being petroleum distillate, it is somewhat toxic to inhale and does harm rubber after a while, contrary to what the maker claims.
-
Fellas, isn't there a special WD formulation for electrical contacts? This is the one I was referring to in my original post.
Unless there's physical damage to the resistive taper inside the pot, a slightly crackling pot is hardly a reason to send an amplifier in. Turnaround will take weeks and with the current state of affairs, postage might not be risk-free either.
Speaking of volume pot in the BHA-1, is it a Noble or an Alps? My amp's S/N is in the 300 range and it was among the first ones to have preamp outputs.
Cheers,
Antun

I've got an RMA# from Mike.
It's not user serviceable after I asked him if I could do something to get rid of the noise volume.
I don't like a crackly volume knob.

Got a question. I read this statement on Moon-Audio regarding the BHA-1 "The Bryston headphone amp is not a 'true' balanced headphone amp even though it has balanced inputs and balanced outputs. They use operational amplifiers by changing the input to single ended, installing a single-ended circuit and changing it to a balanced output for the headphone jack."
James is this true. ??

The inputs and the outputs are a fully differential balanced design (to eliminate noise) but the signal path through the preamplifier is single ended.

MEMO: To All Bryston Customers
SUBJECT: Bryston BHA-1 Headphone Amp Review – Portugal
January 2021
Conclusion:
What can I say?
With exception of some of the headphone amplifiers from Stax and of course, from the valve amplifiers from Sennheiser,
The Bryston is the best headphone amplifier that I know of!
Ample space with several rooms of sound, precise timings and timbres and precious in detail and correction.
Interestingly, BHA-1 is not a recent product. In fact, the Bryston BHA-1 was already introduced with enormous audiophile success some eight years ago and continues to be the brand's only headphone amplifier.
This stability shows how Bryston is a special, coherent brand of ideas and well-defined objectives. But it serves also as a testimony of the great qualities of BHA-1.

James, regarding the dual 3 pin xlrs and the 4 pin xlr stereo vs the 1/4 jack. I sent a email to your team the week of Christmas on the same subject. Is there any wattage/power difference between the 1/4 jack and the 3 pin dual balanced and the 4 pin stereo XLR ?
I think the 1/4" TRS jack will yield only half the power since it uses only 1 of the 2 output stages not sure about the other connections hence my questions

The reason I ask, is I read this on another site where the poster contacted Mike at Bryston and got this answer ""I had contacted "mike" at Bryston about getting all the potential out the BHA1. He stated the there would be a 2X in increase in power per speaker or, a 4X increase for the headphone using the balanced output to the phones."
If that's true , can yall explain how,. thank you
-
The 1/4" output on the BHA1 is TRS, but the Ring and Sleeve connections are Right and Left, rather than the two phases of a balanced connection.
This means that the 1/4" output is single ended, and the balanced outputs will be capable of twice the voltage, and thus four times the power.
Thanks,
Mike

Hey Rob, I was wondering where you were!
Let me tell you, I still find the immediacy and 'slam' of the Sennheiser a lot superior to cans with the reputation of 'slamming hard'. But like everything else in life, it's horses for courses.

Hi All Bryston BHA-1 Users!
Wanted to share some discovery that may be useful to those who uses Bryston player, DAC and headphone amp.
To be frank, I am not an intense headphone user, I have bought the BHA-1 and modified my headphones AKG K701 to a balanced cable to use with the BHA-1 when my kids are babies about 7 years ago... (not to disturb my babies when they sleep).
(https://www.audiocircle.com/image.php?id=223187)
Recently, I have dug out my balanced headphones and start listening to them again (not to disturb my kids when they are studying for exams). Obviously the BHA-1 sounds wonderful with the Bryston BDP-2 and BDA-3 combination. However, it is not as convenient to control volume as BHA-1 does not come with a remote to control volume.
(https://www.audiocircle.com/image.php?id=223188)
However, I discovered that BDA-3 in fact could control the volume as well via the mobile phone! The volume control in BDA-3 is just a slider in the browser and the volume lights are also reflected on the BDA-3 when adjusting the volume! So my mobile phone became my control not only for volume but also the Media Player that controls the BDP-2!

So convenient! Now I can easily listen to music from Tidal on my headphones with the Power of Bryston Music all controlled from my mobile.
I hope this sharing will be useful for all Bryston gear owners.
Cheers!

Use my BHA-1 everyday via Balanced with my HD800s

I haven't been around these parts in a few years. Looking to maybe get a BHA-1 in the near future as I think I want to dabble with headphones for a change. There is another potential amp in the mix but the BHA-1 is a definite possibility.
Now we have to wait for Ontario to open up.
James - My local Bryston dealer closed up shop several years ago. I notice that your website has an 'online shopping' option. Does this mean that I can order, say a BHA-1, direct from Bryston if I have no local dealer?

Ah, thanks James. I sent that request in late last week from the website. However, I have no trouble finding a dealer and ordering direct 😊 It’s time for a refresh so a BDA 3.14 will be in the works eventually as well (to replace my Logitech transporter and BDA-1 combo).

Thanks James. I'm actually ordering one via Solen today. If this transaction runs smoothly I'll likely go through them as I refresh a few Bryston pieces over the year (BDP, BDA, etc.)
Oh, and congrats on the new venture with the Mothership 8)

Thanks - so far it looks good - we are going to be able to manufacture a lot of the parts ourselves going forward.

However, I discovered that BDA-3 in fact could control the volume as well via the mobile phone! The volume control in BDA-3 is just a slider in the browser and the volume lights are also reflected on the BDA-3 when adjusting the volume! So my mobile phone became my control not only for volume but also the Media Player that controls the BDP-2!
...
Greetings!
I apologize in advance if this is a stupid post but I really don't understand any of this. The interface where you can select all the inputs on the BDA-3, is that a web-interface? Is the BDA-3 connected lo LAN? The interface looks like it's Linux-based but I don't think there's a Linux computer running inside the BDA-3, is there?
Or is it an interface for the BDP-2 which is somehow integrated with the BDA-3 so that it allows for input switching on the BDA-3?
Would anyone care to comment on this?
I likely don't have this ability because I have a BDA-2 rather than a -3 and it doesn't have a LAN connector, presuming that's what it's all about.
Cheers - Antun

Hi Antun,
Volume control is a feature in bda3 and yes, bda 3 is connected to Lan.
If you use mybryston.com in the web browser, all Bryston devices that is connected to your network will appear in the browser. You can select your bdp2 or bda3 from there too.

LEONG
Hi Leong!
Yes, crystal clear, thank you!
That tells me Bryston made some internal changes to the BDA-3 compared to the BDA-2 to allow for the LAN connectivity to function like this. That's rather interesting especially since nothing of a sort has been mentioned in the brochure or the usual and mostly useless reviews.
Thanks!

Hi James,
I'm new the AudioCircle but I've purchased several brand new Bryston products in the past. I'm currently in the process of placing an order for a new BHA-1 from an authorized dealer in Ontario. I am planning on using this with balanced inputs from my DAC and balanced outputs (4pin XLR) to my Sennheiser HD800s. I previously owned a BHA-1 from 2016 and was wondering if the volume is the same in the new production units. I saw some posts suggesting volume was changed to a more linear gain but can't find much else. Aside from the new cubed series finished faceplace are there any changes to the new production BHA-1 units?
Also curious to ask what optional upgrades/modifications are available.
Thank you,
Sean
-
Hi Sean
The only option is you can reduce the Gain by 12dB if you feel there is too much gain in the default setting.

I'm sure this was posted somewhere but this thread is 64 pages long... can the low-gain modification be done by a reasonably skilled person at home?
I'm assuming that it involves swapping a couple resistors?

Hi All! I’m a Huge Bryston fan and recently purchased a BDA-3.14 to replace my DIY streamer and inferior preamp.
Was wondering if any of you were using the BHA-1 as a preamp, as well as a headphone amp, to drive your power amp. If so, how is that working out? Please state your system components when replying.
Thanks!

Posted a few years back on using the BHA-1 as a pre-amp and was fairly impressed with its performance.
https://www.audiocircle.com/index.php?topic=121595.0
Few things to be aware of is that if using headphones there is no mute or toggle switch when inserting the phones to disengage the signal to an amp. Of course the work around is to turn off the power amp.......other than that IMHO it makes an excellent pre-amp and worked great with the 4BSST powering a pair of Dynaudio Special 25s and BCD-1 as source. Going from memory it did appear to out perform my BP25 which was in my system for over a decade, the BHA-1 does lack the flexibility of Bryston's dedicated pre-amps but for a minimalist set-up I'd say go for it. :D

I used the BHA-1 as a preamp for over a year. I had the -12db gain reduction done to it, as running balanced lines into a #3Bsst it was just too hot. The sound was excellent, no complaints there, but I finally gave in and went for a preamp with remote control capability. The replacement preamp is the SP1.7 which I run in 2 channel mode exclusively.
In addition to the lack of remote control capabilities , the other thing I don't like about the BHA-1 is the volume control. It's sensitive before 3:00 and again after 9:00 but does next to nothing between those positions. I inquired into changing the volume pot but Mike said that only one works in that unit. Small thing, but I thought I would mention it.
So my SP1.7 is connected to both the BHA-1 and 3Bsst, and I turn on one amp or the other as needed. The BHA-1 just sits there at max volume and I control the volume with the SP1.7. Really wish the SP1.7 had headphone output so I could have reduced component count. Oh well, may someday a BP17.
-
Thanks for the feedback! Appreciate your input.
I’m still not clear about this: When using the unit as a preamp to drive your speakers, does the feed to the power amp get muted when you plug the headphones in? Can’t find anything on line to clarify one way or another!
Sorry if it’s a dumb question, just wanted to clarity this before spending more than I can afford! 😝

Curious if you had the gain reduction done prior to using it as a pre, if I remember correctly the wonky gain on the BHA-1 when I was using it as a pre performed more linear for its full rotation, this was with the 4BSST and a 2B LP pro, much like the BP25 before it.

I didn't need the gain reduction for my headphones. It was only after connecting it to the 3B. The output from the speakers with volume at the 9:00 position was not what one would expect, and that was with the gain switch down on the 3B.
If it wasn't for lack of remote control capability I could easily have lived with the BHA-1 as a preamp. 3 inputs are all I need, and the sound is fantastic.

Guess it all depends on listening habits and the speaker's sensitivity, my Dyns are at 87dB and usually moderately loud listening levels otherwise, if I need to lower the volume its headphones for me. :D

This is in reference to Leong's earlier post suggesting a method of using the volume control in the BDA3 to remotely control the volume to headphones via the BHA-1. I remember that the MM used to have a digital volume control, but we were advised that using it to diminish volume would reduce the bit-depth of the sound. Is that also true when using the digital volume control in the BDA3 to remotely adjust BHA-1 volume level? :scratch:

As far as I know, yes. However, the loss of bits might not be as severe as most people think. The AKM DAC is a 32 bit architecture and given the practical dynamic range of 21 bits of most DACs, you still have 11 bits 'extra' which translates to rozghtly 66 dB. That means you can reduce the level by 66 dB before noticing any loss of quality and at that level, you probably wouldn't be able to notice it anyway. That being said, I really dislike digital volume controls. All arguments aside, one is for certain - one wrong tap on the tablet and your headphones are on fire.

Does anyone know if the HP amp in the BA20 is as good or better than the BHA -1
As this will effect my future upgrade path:
Sticking with my BP17 cubed and adding the BHA 1 and BDA 3 or upgrading to the BA20
Your thought would be appreciated as this is an expensive hobby so I would like to get it right, at this level of components.
Either way I am sure either path is going to sound amazing.
I currently use the integrated HP amp in the BP17 cubed for my Audeze LCDX(2021) and HD 600 which sound fantastic, but this is a temporary measure which I am very happy with until funds allow.

Well, I actually did get a BHA-1 last Summer but due to being busy with housing renovations never got a set of headphones until last week. Ended up with the Arya Stealths and I'm liking the headphone set up, for sure. I'm sure I'll replace the Logitech Transporter eventually but right now it's working fine due to the support of the Open Source Code by other users.

With family still studying and working from home thought it was time to invest in a descent closed back headphone...and the AKG K872 are working out to be just the ticket...not only a great tool for professionals but IMHO also quite musical. They're only 36-Ohm but the the BHA-1 drives them perfectly, for a closed back phone staging is excellent and with every detail in the recording revealed layering is very distinct, maybe the best I've experienced, pristine highs and more than adequate tightly defined base with lots of body...nice alternative to the Sennheiser HD800S when I need to block out outside interference. Some may ask why not Sennheiser's own HD820, IMHO it diverges too much from the open back counterpart but the AKG K872s quite resemble, not only visually but sound wise to their opened back twin the K812s, which I also really like and find they actual improve on them in some areas, base and treble to be exact.

True...but not just Bryston... prices have almost doubled on everything.....
There's one currently available over at Head-fi at a relative affordable price...might be still available.

I must say, the Bryston BHA-1 is the best headphone amplifier I have ever heard and I’ve heard a lot of them. I bought mine in 2012, right after Bryston introduced the “revised” version with balanced preamp outputs which, I believe, was done starting with the unit S/N 301. The price then was 1300 € and was about to be increased to 1400 € because of this added feature but because I bought mine so early, the Vienna distributor was able to sell the revised version at the “old” price. Even though this was really generous, I was still on the fence because, hey, 1300 € was a lot of money and still is! But looking at the prices now, I think I got an absolute bargain!!
Sonically, it’s quintessential Bryston, I think – clear like a bell, powerful yet nuanced, with a great talent for serious excitement.
But, one the most fascinating things about it is the way this understated simplicity works with ANY headphone. I once connected a Grado SR-60i (Grado’s entry-level model) to it and ended up listening to it for several days. I could not believe it could sound so good!
I also own a BDP-2 player and a BDA-2 D/A convertor and really do consider this to be a system. The BHA-1 is very revealing of partnering equipment and to me, there’s really something special about this combination.
A very, very nice amplifier. Here's to ten more years!
Cheers,
Antun

Hello,
I am joining the club of BHA-1 amplifier owners :) Got it new this week, only 20 hours of burning so far. I could listen to music 24/24 with this Amp + Grado GS1000I but I am afraid my companion will ask me to leave the place .... I am really impressed, magnifiscent piece of art. All instruments are so realistics.

Hello,
I'm a new member on this forum and a BHA-1 enthusiast!
Is anyone using the BHA-1 as a preamp driving a power amp through the balanced outputs? I would like to try this, however my amp only has SE inputs.
I should be able to use XLR to RCA cables to make it work right? Just wondering how this set up is working for anyone using it.
Thank you.

Hi vlach, bha-1 works well as a preamp and sounds fantastic, but please read this thread about connecting the bha-1 to an unbalanced amp…

-
What a sweetheart you are! Thank you so much for sharing this link and saving myself from potentially damaging my amp! I'm really glad i followed my instincts and asked before odering these cables!
That said, I find it rather strange that these cables/adaptors are safe on some devices and not on others, i had assumed there was an industry standard for this type of thing.
Another member, 'Jon L' (in the link you forwarded) mentioned he ordered adaptors from Moon Audio however he doesn't mention if pin 3 is floating...i will try to reach out to him or maybe contact Moon-Audio directly to confirm this.
Again, a BIG thank you!
-
A very simple alternative is to get a 1/4" TRS to RCA adapter and use the non-balanced headphone jack on the front to feed your power amp.
-
Wouldn't that be double amping though? I was always under the impression that the rear XLR outputs tap into the preamp section bypassing the amp portion, or do i have this part totally wrong?
-
I believe the preamp output is tapped off the power outputs... but I could be wrong on that.
Also, a TRS to RCA cable is maybe $10 so very cheap to try and just something to have in the toolkit so to speak.
-
I would think that if the rear XLR outputs are meant to be used as a line stage to drive a power amp, then surely these outputs are not identical to the front XLR outputs because usually preamps have higher output impedance than SS headphone amps, but i'm just commenting based on my very 'general' knowledge and i'm far from an expert. I even looked at the schematic and can't really tell.

I did for a while. Got some xlr to rca adapters (from hosa) and used rca cables.

Out of curiosity, did you have to cut off the connection between pins 1&3 on the adapters?

I'm surprised you didn't have any problems, the product description clearly states that pin 3 is grounded. A few posts back Mike from Bryston issued a warning to float pin 3 if using the rear XLR outputs for SE applications. Anyway, i'm glad nothing happened to your amp!
It turns out every XLR to RCA adapter i've looked up has pin 3 grounded. I'm not taking any chances, i will cut off the connection between pins 1&3 just to be safe.
On an unrelated note, I found different circuit topologies when doing a search, notice the four large capacitors in the attached photo? This is different than the photos a few posts back showing the amps on the test bench at the factory, I wonder when this change happened...

Excellent question and, good catch!
Let’s see what the guys @Bryston have to say!
-
Just purchased a BHA-1 a few weeks ago after hearing it at a friend's place earlier this year. It's really an extraordinary amp. Absolutely the most dynamic solid state headphone amplifier I've ever heard, but it also images and stages well and is very resolving. At this point, I feel very content "retiring" from solid state amps with the BHA. My only complaint is that it isn't quite powerful enough for my AKG K1000. I'm pretty sure I was getting the amp to distort with that pair of headphones, but I guess that's what a Dynahi or CFA3 is for. :lol:

Pin 3 on the XLR outputs is an active high current amplifier output, and should not be grounded. Many adaptors will short pins 1 and 3 together to maintain compatibility with transformer balanced sources, and in most cases, as with our preamps, this won’t cause an issues. However, with the BHA1 it is important to float pin 3 instead. Assuming the XLR can be unscrewed, it should be simple to do this on an already assembled adaptor.

Early prototype....also notice the array of male XLR's for the headphone outputs....dah :duh:

Interesting, i didn't notice the male XLRs...the photo was taken by Ken Rockwell at the 2012 CES show.
-
Hi!
The male XLR connectors are optional, it doesn't mean the specimen shown was a prototype. I don't know if this option is still available though. At one point you could also have locking XLR connectors.
As for the balanced preamp outputs and converting them to single-ended, I must say fellas, this is one of the more interesting things I've recently read on AC!
Cheers!
Antun
-
It is interesting indeed. I just completed this little project using this XLR to RCA adapter which was easy to open and cut off the connection between pins 1&3.
I figure why not use the free line stage that comes included with the amp. Now the preamp section is driving the power amp section of my vintage Yamaha CR-2020 receiver which is driving my HD800 (balanced) via the speaker taps and i must say, it is a significant step up; full bodied, rich, smooth, effortless. Gravity is lower. Mass is higher.
I kick myself for not doing this years ago!!!
Total cost: $15

Finding that I'm using the closed back AKG K872s more often then the Sennheiser HD800S and HD660S thought I'd let the 660s go and added a second pair of closed back, but one with a completely different perspective and presentation than the AKGs, the Focal Elegia..... took a little while for me to warm up to them but finding they complement each very well and the BHA-1 does a stellar job on both.

Picked up a balanced cable for the Focal, overkill for a 32ohm phone.... but ...this way I can have the K872s plugged in simultaneously. :D

Well the Elegia is 32ohm so more than enough power even on low gain but like many low impedance phones, think Grado, they like current and that's where the advantage comes from adding the BHA-1 over an output from a portable device or smaller amp. Even though the Elegia was designed for portable operation a powerful amp with clean power keeps the Elegia drivers under control, (Focal changed membrane thickness from 75 to 110 microns on their closed back models), especially with regards to high and low frequencies. With the help of the BHA-1 base is extended and full, while higher frequencies remain glare free with zero sibilance, two often quoted short comings, the closest I can think from personal experiences is that the Elegia is like a souped up closed back Sennheiser HD650.

With regards to comparing the K872 to the Elegia, the AKG IMHO are extremely linear, with the 872 the sound stage is usually at arms length and spread out (quite good for a closed back) in a coherent fashion, similar to the HD800 but the AKG having more perceived depth and better defined separation, same goes for the frequency balance...the Elegia on the other hand brings the performance into one's head, there is some sound-stage width but there is the impression of everything being overlapped, fuller and up front, so an overall more intimate performance. Thanks to the drivers in the Focal, maybe with the help of the BHA-1 8), do keep everything distinct and clean so one can clearly hear the separation between instruments and performers so that the sound is never a messy blob.

Well the Elegia is 32ohm so more than enough power even on low gain but like many low impedance phones, think Grado, they like current and that's where the advantage comes from adding the BHA-1 over an output from a portable device or smaller amp. Even though the Elegia was designed for portable operation a powerful amp with clean power keeps the Elegia drivers under control, (Focal changed membrane thickness from 75 to 110 microns on their closed back models), especially with regards to high and low frequencies. With the help of the BHA-1 base is extended and full, while higher frequencies remain glare free with zero sibilance, two often quoted short comings, the closest I can think from personal experiences is that the Elegia is like a souped up closed back Sennheiser HD650.

Wow, if the Elegia is a souped-up HD650 as you say, then that’s high praise indeed! I am intrigued. I didn’t know about the increased thickness of the diaphragms/domes on closed-back Focal cans. Were you specifically opting for a closed-back to shut out external noise or do you simply like the sound of them?
Also, I can tell you like the K872 a lot and actually find them superior to the HD800 In some respects, namely the linearity. This headphone alongside its open-backed cousin, the K812, is a polarising one – some people hate it, the others love it. The professional reviews have been nothing but negative and yet, it is one of the most highly regarded cans on internet stores like Thomann, more so than the usual suspects like Audeze LCD-X which, BTW, I don’t like at all and find significantly inferior to the LCD-2 Classic.
You are absolutely right about the Grado headphones. Even though everything indicates they should “sing” with a low-powered source, that is simply not the case and even the SR-60 will blossom when paired with a decently powerful amplifier. The BHA-1 does make it sing.

Funny, over the years I've owned a HD650 3 times and also the HD6XX but sold them always for the same reason, they were never engaging enough for my personal tastes. That opinion changed with the HD660S but with the HD800 and K872s around they were gathering dust. Still the later 2 with their superb technicalities are a bit stand offish with some recordings and genres of music and as I still require some sound isolation thought, after reading numerous user reviews, I'd give a Focal closed back a try to recapture some of that intimacy.
With regards to Focal's driver for their closed back.
https://www.focal.com/sites/www.focal.fr/files/shared/catalog/document/stellia-elegia_whitepaper.pdf
Yes I do really like the K872 and the 812s for that matter, oddly there are only a hand full of negative reviews on the K812 due to their measurements but they get repeated ad nauseam and probably by many that have never owned them. Now having said that, the presentation of the K872s is rather quite unique, always reminds me of getting a direct feed from a studio or monitoring a performance directly and may not be appreciated by all .... and I can easily see why the Sennheiser HD6xx series have a long time following. Maybe it's from all time spent in my own studio but the AKG K812/872 tick more than a few boxes for me, and while the HD800 series are a great sounding phone, relatively speaking they can come across a bit too ambiguous with less layering and depth.
Technically IMHO I believe the BHA-1 brings out the best of all these phones, but as the saying goes "garbage in garbage............ :thumb:

Hi Rob!
That’s really interesting! I have had the HD650 as well and sold them for the same reason you did. Now, as I grow older, I wonder whether I should have done that. At the time, I bought the original T1 from Beyerdynamic. I was using tube amplifiers at the time and the combination was rather magical so I didn’t think I was missing the HD650. I was helping out a local manufacturer of tube amplifiers but there was an incident and the T1 was destroyed by DC offset from one of the amplifiers. It was never repaired to my satisfaction so for a while I was without a headphone. I then bought an HD800 and really never looked back. I find the BHA-1/HD800 combination exhilarating and find the BHA-1 an ideal amplifier to power the HD800.
My first real quality headphone was an AKG so I’ve been admiring the brand for around 20 years. Over the years I’ve learned to trust my ears which, with all the nonchalance and pretend-know-how with the large majority of reviewers out there, seems to be the thing to do. The hassle though is the difficulty of trying before you buy and there really isn’t a way for me to try a K812 whichis something I would really like to do.
I have 10 pairs of new-old-stock K135 cans which I got from a neighbour who didn’t know what to do with them and now, I don’t know what to do with them. The padding is all gone and has turned into goo but I’ve had the speakers unsoldered, thoroughly cleaned them, soldered the speakers back with a Cardas solder and purchased and installed new padding. They’re very difficult to drive but to my ears, they exhibit all the qualities I find so attractive with vintage AKG phones. A friend of mine, the frontman of a very successful band in Croatia, asked for a pair because he finds them well-suited for vocals. I am not surprised because this exactly what I like the old AKG stuff for. They look a bit weird but in this day and age, weird is considered cool again.
As for the Elegia, were you able to purchase it new? Is It still available? I have never heard a Focal headphone so can you please say a few words regarding its dynamics compared to the K872?
Also, you mentioned you own a studio. May I ask what kind of production do you do and if you do it to make a living or as an amateur?
Cheers,

Hi Antun
I'll try not to get too long winded..... :popcorn:
Yes try before you buy is always is always ideal but problematic, especially today...luckily I was able to borrow a pair of K812s for a few weeks, but that was just after I picked up my HD800S in 2016...I was expecting the worst but came away wishing I had gotten the AKGs instead. :scratch: So I had a relatively good idea what to expect with the K872.
Depending on where you are located Amazon UK currently have the K812 for a reasonable price, and as they can ship to Canada without VAT I've been tempted.
But even though I really like them is not any indication they have global acceptance ... YMMV ... lol
Focal, relatively speaking, are new to the headphone world, starting in 2012, AKG started with headphones in 1949 and Sennheiser 1972 and both have a long history of diaphragm development for microphones prior to doing their headsets, so basically a new kid on the block. I did manage to audition the Utopia but for their asking price was not overly impressed and preferred the HD800S and the K812s for that matter.
Recently wanting a second closed back to compliment the K872s the Elegia was a curiosity and I was able to pick them up locally from a gentleman who gave them literally an hour of use as he preferred his IEMs, so basically new, they were a silly price so thought I'd give them a go.
Initially I agreed with his impressions and had a bit of buyer's remorse but after a few days the phones really did change (controversial of course), opened up completely, lost their edginess and the sound-stage improved, even Focal state in their manual a minimal 24 hr break-in.
For a closed phone they are completely different from the AKG K872, more akin to having 2 speakers placed on either side of the head, which they are, compared to their other phones Focal did some revisions to the driver and cup but the AKG IMHO are a much more sophisticated endeavour and sound more opened backed than closed. Oddly, Focal remind me of my past Grados even though design wise they are totally different. Both phones are relatively dynamic but the Elegia are more up front, the AKG can step back but show their presence when needed.
The Elegia has been discontinued and replaced by the Celestee but are still widely available and for about 1/2 or less their original pricing.
To be honest though.. I'm a bit out of the headphone loop, and probably an old stick in the mud with my AKGs and Sennheisers...brand loyalty brand and all that, I'm happy with them but there are quite a few new offerings out there..still undecided with Focal as they have stiff competition with the much more affordable Sennheiser HD600 series, the closed back Elegia is the odd man out.
As for studio work, starting doing tape manipulation, Music Concrete prior to going to University in the early 70s and later I had my own small electronic music studio as an Electro-Acoustic music composer. Did some on-site recording for small jazz and performance groups, so not really commercial work.
Should note, got my first Bryston 2BLP back then to power my studio monitors...and the 2BLP pro prior to the BHA-1 also did a great job of bringing the K240DF (my first AKG 1977) and K501's headphones to life..... way back when.
...as for your K135s...always fun acquiring old new stock of something.

Thanks so much, Rob, for not restraining yourself! 😉 Hey, I get carried away too!
Onto your priceless comments regarding the K812, now I have to try them!
Your enthusiasm reminded me of my own when I first saw and heard the Audeze headphones, here in Croatia. Though the staff was a bit unfriendly, I didn’t let that ruin my afternoon so I took my time and listened to the LCD-2 Classic, LCD-X and LCD-3 (precisely in that order) for a good two hours. I was pleased with the sound of the LCD-2 Classic as the sheer size of those diaphragms made them sound big and powerful. Even though I was listening to them through their Marantz headphone amp / DAC and with their choice of music, it was clear the detail retrieval wasn’t as good as on my home system (BHA-1/HD800). But I wasn’t looking for more of the same, just something vastily different, which the LCD-2 Classic certainly was. I was really excited and full of anticipation what the next one up, the LCD-X, would bring. It, to my disbelief, was a complete and utter disappointment! I just didn’t know what all those reviewers were talking about, hot this headphone is the ideal reference and an HD800 equal etc. It simply wasn’t. Midrange and top end were ridiculously over-done and riddled with grain. Absolutely terrible. The LCD-3 was an improvement on the LCD-2 Classic, with a more balanced set of features, like the liquid and lovely midrange. The LCD-X wasn’t even a contender and it was one of the biggest disappointments in HIFI that I have experienced.
So, now I’m thinking that, like you, I am different in some way and that I should not necessarily believe what the reviewers are saying and should simply try the K812 out myself instead of discounting them because a reviwer said it wasn't good. Perhaps the fact we have an actual music background accounts for something in this respect but whatever the case may be, I am less and less keen on trustung the reviewers. I really need to find a way to try the K812 out.
Unfortunately, it won’t be through Amazon.co.uk because after Brexit, all goods imported from the UK are subject to VAT and a world of trouble with the customs. I will check with an audio-visual distributor from whom I’ve bought before.
Is your K812/K872 an Austrian or Slovakian-made model?
The Elegia sounds like an interesting headphone too. It’s interesting that you do not find it more dynamic than the K872, just more up-front. I would agree that this is certainly a description that fits a Grado headphone, at least the on-ear models. I find that even HD800 can display excellent dynamics when paired with excellent amplification.
I really like the fact you have some experience with recording of small jazz ensembles and electronic music. I suppose you used open-reel tape for recording back then, right?
I remember you showing your 2BLP connected to your BHA-1 to drive AKG headphones! I am very familiar with the K240DF – some of the flattest and colourless (for better of worse) cans this world has ever seen! They’re notoriously hard to drive but can sound remarkably good if properly powered. I have never heard a K501 and to this day regret not buying a pair while they were still sold in stores – too much money for an engineering student back in 2005. The “burn-in” issue is a rather interesting one. While I cannot vouch for the Elegia, I can say with certainty that a K701 changes so dramatically that it sounds like a different headphone after 200 or 300 hours of continuous playback. The thing about the K701 is that it is unusually hard to drive which you could never tell just by looking at the specs. Like always, the “secret” is in the inner workings and the flat-wire voice-coils which is a similar assembly being used in ATC speakers. They too are a lot hungrier for power and like the AKG, require a period of adjustment to sound proper. The K701 is unusually well-suited for really loud playback which is again to the voice-coils which, apart from being densely wound, are clearly larger in diameter as well so the chance of them overheating is lower. Like you say, AKG knows their stuff. Those guys hold something like 60 patents in the field of electroacoustics and I learned a bunch just by reading through their whitepaper.
So, here’s to getting carried away!!

Hopefully you do get a chance to hear them, while the K872 do remind me of the K812, they are a closed back and if not sealing correctly will not sound their best.
An affordable alternative if you are not aware, the crew from AKG's Vienna location after it was closed down formed Austrian Audio.

I'd be interested in hearing their Hi-X65 and Hi-X60 as from reviews they may be similar to the K812 and K872s which they had a hand in developing and I like their portability.
As for the Focal, I find this young lad (although not agreeing with all he has to say)...has a good grasp on describing them.

Hi Vlach
With the HD800 and T1 I think you have the basis covered, my recent conversation on the K812 was only because I recently picked up the closed back K872s as I wanted an option for when an opened back was not appropriate for proper listening but technically on the same level as my HD800S. Yes they are different but both satisfying in their own way. Funny hobby though and relative to owning high end speakers, high end headphones appear somewhat affordable so it's easier to scratch an itch, or add a different sound for when in the mood, which is where my new Focal Elegia come in as a replacement to my Sennheiser HD660S. I've not had an interest in switching out the BHA-1 though. :thumb:

Hi Rob!
Oh, I’d say that the Austrian Audio fellas had more than a hand in the development of the K812! Sure, the HI-X65 looks rather nice.
Is your K812 made in Austria or somewhere else?
I had a long chat with the fellow who did that video several months ago. He did an interview with top managers from Sennheiser and Sonova (a Swiss company that now owns Sennheiser’s consumer division). This was right after Sonova/Sennheiser let off hundreds of people even though the official stories were completely different! This guy, the reviewer, did not ask a single question that mattered. For someone who pretends to be an industry insider and an objective source of information, as any decent HIFI writer (and I’m stressing the word “writer” here), the interview seemed like a friggin’ sponsored ad for Sonova and Sennheiser. He was furous when I pointed out to his failure to ask the questions that mattered to the end consumers, even though the customers might not be aware of those questions. Questions like why he didn’t ask them about the closedown of Sennheiser’s customer support centre in Zimbagasse, Vienna. Some fifty people were laid off there and hundreds more elsewhere. As a writer, his dedication to the truth should be uncompromised but, as things stand, I told him the only thing he will ever be famous for is his uselessness. Sorry, but I know BS when I see it and I have no tolerance for it, no matter who it is.

Hi Antun
Don't currently own the K812 just the K872 but the 812 that I did borrow where made in Slovakia.
Really don't follow many of the reviewers on Utube, just hearing people jumping on the bandwagon going on about a product, any product to hopefully make a dime from the amount of hits or referrals.
Yep a lot of BS around..the ones that get me are those that vehemently trash a product and then the minions that never even tried the product carry the flag.
Ok there are products that just miss the mark but even the lower end stuff these days is rather quite good. If a product is not to your liking just move on, life is just too short. But sure if one really likes a product, speak up, but IMHO no reason to drag a product, the company and employees through the mud.
Back at the beginning even Bryston were shunned by some as they came from the pro market and considered not suitable for "Hi-Fi", decades later some still quote that :| ....but back in the 80s my first 2BLP somehow made it from the studio to the living room replacing my Maranz amp "Different strokes for different folks":lol:

Hi,
Some advice needed, I have my 'Headphone/office' system which currently comprises a BDA-3.14, BHA-1 and a Naim NAP100 power amp soon to be retired for a Bryston 4B3, then Mission QX speakers.
I don't suppose there is any way of getting the 12V triggers to switch all of this on and then manually switch off the 4B3 when using my headphones. The 4B3 seems to be the only one with a trigger output the other two are inputs so manually switching that off would switch it all off.
I do have one of those Emotiva 12V hubs spare if that would help to split any signals.
Many Thanks
Stuart

The BDA-3.14 and BHA-1 have trigger IN, the 4B3 has a trigger IN with a pass-through to trigger OUT. Turning on the 4B3 manually with the rear switch set to LOCAL does not enable trigger OUT.
I believe you can do what you want by connecting the Emotiva ET-3 trigger OUT to the 3.14 and BHA-1, and leaving the 4B3 on LOCAL for manual on/off from the front power button. Then set the ET-3 to enable trigger OUT when it is plugged in / receives power.

Thanks, that makes sense use the Emotiva to create the trigger voltage as the others are only inputs.

What's the process for going from 110v to 220v on the BHA-1? Is that a trip to Bryston, and if so, what's involved?
-
Yes the transformer and some parts need changing

I have the following signal path:
BDP-2 => USB in to BDA-3 => RCA out to CD in 11B => RCA Main out to 4B in => A3's
I'm considering adventuring into the high end headphone experience with the intent of
adding a BHA-1 to my system. If I have read the manuals correctly it seems I could connect:
- balanced XLR out from BDA-3 to balanced XLR in of BHA-1
- RCA out from BDA-3 to RCA CD in of 11B
- RCA Tape1 OR Tape2 out from 11B to RCA in of BHA-1
Basically, I want to have the BDA-3 direct connect to the BHA-1 for headphone listening but
also connect to the 11B / 4B / A3 for speaker listening. I would also like to listen to other analog
sources (tuner, TV, phono) off the 11B through the BHA-1. Have I got this right ?
-
yes, that sounds right.
-
yes, that sounds right.
thanks for confirming. I picked up a mint BHA-1 last night from a CAM member. I have my 11B tape 1 out
to RCA in on the BHA-1. Currently waiting on a pair of XLRs to run BDA-3 direct to BHA-1. I gave a brief
listen to some Tidal content with an old pair of Shure cans through the 1/4" outlet on the 11B and then
through the BHA-1 : noticeably cleaner / quieter. I now know why you would use the BHA-1 as a pre-amp.
Now I just have to find suitable headphones ...
The listening room is in the basement and the goal behind the foray into headphones was to enable
everyone else to sleep when I stay up late listening. I'm thinking something open backed planar with
a balanced XLR connection budget $1500 - 2500 (used or retail). Any suggestions ?

Audeze.

I'd also recommend looking at the Audeze, specifically the LCD-X, MM-500, or LCD-3 models. You'll want to audition them to compare as they sound different from each other and everyone has a preference irrespective of the different price points. The LCD-MX4 is $3000 so a used one could fall within your budget.
-
I have read great reviews about the Audeze line. Unfortunately no dealers with that brand in my area and
few even have in store auditioning. I may be able to audition some Meze and Dan Clark next week.
-
You can do that or go for smaller speakers that perform well and linearly at low SPL. I use both my Audeze and Amphion monitors late at night.
Btw do you have any insulation in your basement ceiling?
-
no insulation. I'm keen on a very good set of headphones, it just may take some time
to find the right ones for me. May have to make the drive or GO into TO ...

Hi fellas!
It’s interesting that the usual recommendation is Audeze. My experience with this company is not all positive so let me share my observations.
Like most people, I have read plethora reviews, fulsome in the praise of the headphones and the brand in general. It made my disappointment that much greater. I have not listened to all the models but I did extensive listening sessions with the LCD-2 Classic, LCD-X and LCD-3.
The often-recommended LCD-X isn’t even a contender in my experience. It is very grainy which is probably why people think they sound detailed. Quite the opposite actually, I found it very poor in resolution, not being able to resolve harmonics and sympathetic string resonance of a piano at all. The sound image as a whole was big which isn’t surprising considering the physical size of the diaphragms but the actual width of the image was only average. I find the price completely ridiculous for what it offers. It is even more ridiculous that it is often compared to a Sennheiser HD800 because of the similarity in price. The Sennheiser is a far better music-listening experience in every way.
The LCD-2 Classic was actually a whole lot better. It was still grainy but to a lesser extent which gave the impression of a slightly harder-sounding upper midrange. As a consequence of that, it sounded better with male, lower-reaching vocals than with female ones. Still enjoyable though. The image was just as big as with the LCD-X but this time with more girth and grunt in the lower octaves. It is a better headphone than the LCD-X, through and through.
The LCD-3 was better still because it was more refined in the upper midrange and so, being able to bring out more nuance from the music I was listening too. It also appeared to have worked equally well with both male and female vocals. It is a very pleasant headphone to listen to, analogous to what Harbeth represents in the world of speakers. Still, at their asking price of 2000 €, they’re very expensive for what they are since the same midrange quality can be found with the likes of Sennheiser HD650.
But the overall positive impression I had of Audeze has been overshadowed by the simply unacceptably poor LCD-X. No doubt, there are some clever people over at Audeze and here I primarily think about their sales and marketing folk. High-profile reviews by known publications and even people from MI channel have proven successful for them.
The bottom line? Don’t believe everything you read online, especially when the feedback is overwhelmingly positive.
Also, keep in mind that the mentioned MX-4 uses the same diaphragm as the LCD-X. As far as I know, both are 20 Ohm impedance which is too low to be used with a BHA-1 in a balanced mode. This amplifier has an output impedance of 4 Ohm in balanced mode which would amount to a damping factor of 5 and probably affecting the response of the headphones too much.

thanks for sharing your info on the Audeze LCD line. I had the opportunity this week to audition a used mint Sennheiser HD800.
The seller lives close by and was kind enough to bring them over to try on my Bryston system. I could appreciate all that I had
read in reviews and forum posts but listening to music I know on them and talking about them with the seller was a rare and valued opportunity.
This being my first listen to anything of value over $300, I was expecting to be blown away, but the HD800 didn't do it for me.
The seller twigged me onto the LSA HD-Diamond and down that review / research rabbit hole I went. A set along with 4 pin XLR
cable upgrade are on the way landing sometime next week. I will post my impressions after burn in.

Hi!
Oh, the HD800 is most certainly not for everyone! To me, they’re perfection for classical and musical genres where acoustic instruments are predominant. Like with a finely tuned instrument or I suppose, a sports motorcycle, you have to know what you’re doing. That’s why I never really recommended them to anyone but it’s odd that after ten years I haven’t found anything better for acoustic music.

Your opinion of the LCD-X must be based on a defective model. I use mine (March 2022 production date) on my BHA-1 via the balanced output and it's a match made in heaven. No problems at all driving the 20 Ohm impedance of these 'phones. I also have the Senn HD-800S and while they have a bigger soundstage they can't match the dynamic range and bass response of the X's. I used to own the LCD-2C but they were to rolled off in the top end and they sounded less precise in the bass. They did have a bigger soundstage than the X's, however.

Like I said in my post, I know that many people praise the LCD-X. I just didn’t find any justification for it. They were not defective or broken. In fact, the staff in the store clearly preferred the LCD-X as do their customers. Of course, more $$$ means more for them. They are outrageously overpriced and unacceptably low in mid-band resolution.
As for the impedance, I did not say they will not work. I said the low impedance will change the frequency response, and with a 5x damping factor, it does.
If you are enjoying your LCD-X, then good for you!
Cheers!

"overpriced" re: the X's is very relative, considering it outperforms the more expensive 800S' in all but soundstage width and the last ounce of "air". Most listeners, myself included, find the X's to be more accurate in general tone (partially due to the accurate full range bass absent on most dynamic driver designs). I find the midband on the current X's to be more accurate than the 800's. Output impedance on the headphone amp is not critical for most applications and the planar tech in the Audeze line gives a perfectly flat impedance response across the entire frequency band, unlike dynamic driver models which can vary widely. The BHA-1 and other high quality amps are coasting and providing a good damping factor on the X's.

Hello!
Like I said, if it sounds good to you, then that’s all that matters.
That being said, I must say, when I evaluate equipment, I apply ALL my experience and knowledge. That includes more than fifteen years of being a musician in an orchestra, playing everywhere – from the smallest of venues to large concert halls and open town squares throughout Europe, as well as recording three compact discs in the largest production studios here in Croatia. These, mind you, are the “reference recordings”, both to me, but also because some of the most talented people were involved in their creation. So, when I talk about what is “natural”, I really do have a point of reference and a fairly good idea if the equipment translates the recording well or not. Don’t think I am saying this to reach a higher moral ground in this discussion – but it is what it is and if I said it any other way, it would be a lie. In short, I am not interested in “general consensus” on how something sounds, so nothing that you can say, or anyone else for that matter, will make me feel differently about a piece of equipment. That does not mean I don’t take other people seriously or value their opinion but forgive me for saying so, not every opinion is equally valuable (and this is true in every profession).
It's like trying to get a job – having no formal education and/or field experience doesn’t bode especially well for you at a job interview. But these audio reviewers… People trust them blindly and buy whatever they recommend. Sure, it’s not exactly structural engineering and no one will die from buying a substandard headphone, but someone might die if an unqualified engineer is hired to design a cable-suspended bridge. See my point?
I always suggest people to buy tickets for an opera or to go listen to a symphony orchestra. It can be a very rewarding and humbling experience. But many people buy expensive (overpriced) audiophile-grade recordings thinking they’ll get closer to the actual musical event when in fact it is SO far from the actual event. In fact, the musical event everyone has in their heads might not have even happened – the bass and drums might have been recorded in separate (smaller) rooms and the other instruments may have been layered on top of them during some other session or even in a completely different studio. So it really is the funniest joke when people (reviewers included) say something sounds as close to a live event as they’ve heard it or even better, it sounds like the artist intended it to sound. Would it help if I said most artists don’t even know what they want, or maybe they do but they just don’t know how to achieve it. Or maybe they know all of that but the studio time is so expensive that the first draft will also be the final product.
As for “a good damping factor”, I would really like to know what that is. 😉 It’s either sufficiently high or it is insufficient.
But, like I said twice before, I am happy that you are enjoying your Audeze LCD-X.
Cheers – Antun

Audeze used to use the BHA-1 in their demos and last I heard, James Tanner and Chris Russell both owned LCD-3s. Hearing that headphone over a Bryston system just a few years ago made me want them rather badly. They were unbelievably clear and lifelike. However, when they decided that their own headphone amp should be a tube unit designed by Bascomb H. King and they began making different models that sounded very different with deliberately ambiguous marketspeak essentially proclaiming all of them to be the best, I became reluctant to give them my money. I suppose I'm spoiled by Bryston's honest and straightforward business model.
BTW, I recall that when Rin Choi tested the LCD-2 using objective instruments, the results were splendid. Another site also doing a proper laboratory test on a recent, much less expensive Audeze model showed very unsatisfactory results. Your choice of recording may or may not reveal flaws in hardware which is why great patience for a massive investment of time and a willingness to gamble are necessary in the absence of a company one can trust completely.

Anyone else catch the slightly new configuration?
(https://www.audiocircle.com/image.php?id=250931)
https://bryston.com/amplifiers/bha1/
Personally I would have liked to have seen the inclusion of a balanced 4.4mm Pentacon and not sure if anyone actually uses the 2 mono L & R XLRs?
James,besides the rearrangement of the output jacks any other changes under the hood?
-
No changes under the hood.
Studios use the mono L/R
james

Gotcha...of course on the dual XLR.

Recently added the "New" Sennheiser HD660S2 to my headphone roster.
Contrary to the lower impedance HD660S which performed more less the same across most amps the Bryston unexpectedly, or expectedly, brought the new 300ohm S2 to life with deeper and more authoritative bass, clearer highs and wider and deeper layered soundstage.

some configuration questions involving BDA-3, BP173 , and BHA-1. I currently run
BDA-3 balanced out to BP173 balanced in and BDA-3 SE out to BHA-1 SE in.
BP173 balanced out (variable output number 1) to 4B3 balanced in.
I'm looking for the best input configuration for BHA-1: all my sources for BHA-1 are digital
and controlled by BDA-3 (CD, BDP-2).
1) keep config as is: BDA-3 SE out to BHA-1 SE in
2) BDA-3 balanced out to BHA-1 balanced in, BHA-1 balanced out to BP173 balanced in
3) BDA-3 balanced out to BP173 balanced in BP173 balanced out (variable output number 2) to BHA-1 balanced in
I'm not sure 3) even makes sense unless I send the BP173 to Bryston to have one balanced output 1
converted from variable to fixed. Any idea what that would cost ?

I'd keep the configuration as you have it, having only the BDA-3 as the common component.

Am I correct in saying that the BHA-1 now has the low gain mod as standard?
-
Hi - no the low gain is only on a special request.

I wanted an SE output (RCA) to feed my tube amp, Schiit Folksvangr. Unfortunately, BHA-1 doesn't have one. May I plug a 1/4 inch to RCA Y cable to the front headphone jack to achieve this? Any negative impact to safety and sound quality?

May be a mismatch, you are better off using a pair of Female XLR to RCA cables. (unless of course you have one of the first BHA1 without the pre-outs)

To my knowledge, it is safe to go from RCA outputs to xlr input using that kind of cable, but it may damage your device if you go the reverse way. I think XLR outputs have higher voltage that may damage device with SE inputs. Is that true?

Balanced has a different wiring scheme, +, -, and ground, so yes is it very important when converting either way to use just the + and ground. The Monoprice cables that I've used do this correctly, not all do and things can get toasty.
And yes balanced has normally double the output, not always but that is not what will cause problems, it's incorrectly combining the + and - creating a possible short. Sadly some RCA to XLR adapter do this. : (

I had bha-1 for a couple of weeks. I really love it and want to keep it. It is an earlier version from 2014. I'm curious if there were any changes under the hood in those newer units that may affect SQ? I saw a couple of very new units popped out on market, but I wouldn't bother if there was no change :)
-
Only change was after SN 50 we went with a balanced pair of output XLRs on the rear so you could use it as a preamp.

Hi James...
Over in the Head-fi forum someone was curious about......
"But for what is the single blue electrolytic cap at each of the four power stages? Cap in series to output?"

Hello. I am looking at buying a used BHA-1. They seem to pop up on CAM pretty regularly. If I was to buy one that was several years old and didn't get the receipt for warranty purposes, would it be worth it or recommended to send it in for a refurb or inspection?

At that young-ish age, my guess is that it would still be in perfect working condition. So I'd probably listen to it before deciding whether or not that was necessary. If it did end up needing refurbishing or something, that might imply the seller wasn't completely open about the condition of the unit.

Thanks for the reply.
