Introduction

I have been a while writing this review, but as you will come to understand the Vista Phono 2 has demanded a serious amount of "chair time"!

Prior to the arrival of the Vista I have spent years aquiring equipment and fine tuning my setup, in my dedicated listening space. My final lineup has been so wonderful despite many auditions I have not added any new gear in over a decade.

The Sota/Eminent combo is a well known symbiosis.

The McIntosh Mx-117 has a unique and maybe the best MM phono stage made.

The McIntosh Mc-2155 is legendary

The Spica Angelus (Angelii?) in a small room are amazing.

"Dark Matter" interconnects....Cardas and Switchcraft.... beautiful!

"White Lightning Moonshine" I built them and never looked back!

Back in the eighties I had been listening to the Monster Alpha Cartridge, designed by Hisayoshi Nakatsuka of Zyx fame, built by hand, and highly compatible with the ET arm.



The Audio Vista Phono 2


Jump forward to 2016 and on one of my rare boxes of audio cleanout days, I discover an unopened Monster Alpha 2! The Mx-117 has a truly superb MM phono section but will not accomodate the 0.3mv of the monster.... phono stage shopping!


I came across Boris and Vista Audio through my phono stage research. Reviews of the Phono 1 and 1+ were credible, written without encumberence of sales,  by audiophiles like you and me. In my best "Serbian" I contacted Vista in reference to a tantalizing photograph of a "Phono 2" printed circuit board prototype.

Firstly I discovered Boris speaks perfect english, and that the Phono 2 was indeed a prototype that he was working on. I gave him the specs for the Alpha 2, and with the variable loading and gain we believed a good match would be possible.

I offered to help fund the project, after all where for a few hundred USDollars can you get a hand made phono stage with variable load & gain? My offer of funding was rejected as Phono 2 was already in the works and would be available for sale after thorough testing was complete.

Wow a boutique audio manufacturer in a stable financial condition, who was willing to bring a product to market properly!

I immediately pledged to be patient.

Patience apparently is rewarded. Testing of the Phono 2 took many months. For some a wait like this drives them to turn elsewhere, to me this demonstrates the absolute dedication of a designer/manufacturer to his craft. Boris maintained contact with me throughout, and finally offered me serial # 4 which I promptly purchased and had him sign the unit.

Shipping from Serbia to the USA is apparently very inexpensive, and super fast.... nothing however prepared me for the packaging I received.....encased in a plain wrapper, within a custom six sided polystyrene enclosure, was a printed sleeve wrapped foam case cut out for the Phono 2 and power supply. This is how you pack and ship, absolutely 5 stars!

That first weekend I installed the cartridge, Phono 2, and the extra pair of interconnects required. It took a couple of weeks experimenting to settle on tracking force, VTA points for various record thicknesses,  and gain and loading for the cartridge. This also allowed about 50 hours or so for burn in.

On the Phono 2 I ended up with 65db of gain and 147ohms loading. I set the filter to 10Hz fast rolloff.



Listening


I have tried to be as varied in my listening as possible in order to give a review consistent with many musical genres.

The Vista Audio Phono 2 keeps giving me one word...... "precision"

The Phono 2 can throw an immense and deep soundstage if required, yet also can deliver an intimate space or line array if the source requires. The soundstage is always reflective of the space required not overblown or contained just precise.

Instrumental positioning is extremely acurate, air and note placement again precise.

The following are excerpts from my listening notes.

Diana Krall live in Paris

The audience surrounds me, the band extending well beyond the speakers, the piano peddle noise draws attention, the unusual way Diana pronouces "S" in words.....


Stan Getz/Charlie Byrd Jazz Samba

The soundstage!

Deep, wide, the precision of instrument placement. The tone emanating from that saxophone.


Muddy Waters Folk Singer

The chairs creak!

That Organ is playing in my kitchen! (Kitchen is on the right side of music room wall)

The studio air just "clicked" on!

This is the best blues recording ever!


The Bee Gees Gold

Intimate...the difference between their voices is startling, at any time even on harmony I can pick each one.

This is beautiful. They are so talented.


Emerson Lake & Palmer Trilogy

Unlike the instruments firmly located in space the synthesizer sounds swirl around me even overhead "from the beginning" has never sounded like this!


La Boheme Pavarotti/Berlin Philharmonic

Full orchestra and chorus soundstage huge!!

Pavarotti in his prime everyone should hear this!


Belafonte at Carnegie Hall

I have been transported to another place and time! Harry walks around the stage singing and talking to me while the audience laughs, applauds, and sings along all around me


Pink Floyd Dark side of the moon

Rotary speaker overload... those solos, the highs the harmonics. AAA+++


Conclusion


With the Phono 2 I wish I could convey the shimmer, the way notes hang in the air, the accurate musical bass.

The exquisite placement of instruments, artist, and backup vocalists on the realistically sized stage.

If you are like me with a lifetime of musical enjoyment and are looking for a phono stage, look no further than Vista Audio Phono 2. She will serve you well through the years to come, integrating with your future systems or cartridges.



Final Thoughts


The Phono 2 gives you everything you want, quality, adjustability & compatiblity all wrapped up in a boutique package at a price so reasonable you wonder why this is not on every "class A highly recommended " list on the planet.

Then you realize Boris cares about music, does not place full page ads, buy lunches or send reviewers gifts.

I say bravo Boris and Vista Audio, you have a truly great phono stage that really plays music!

Hey Den,

I am checking the tracking on Serbian post office's site (it offers little more detail). Your and Steve's preamps left Serbia on March 2nd. Next tracking info will come when US customs scans the package. Soon, I hope!

Thank you,

Tracking does seem to be slow this time. I figured it had to be somewhere in the last 10 days.
NY customs usually sits for 4 days but noted as such. NO bother though. It shall arrive.
 As always ........

Hello bacobits1.

 Just wondering if your Phono-2 started moving from Serbia. Mine hasn't moved since Feb 2nd.
I know it will get here, just wondering if you've seen any movement.

Thanks.

As a matter fact, just checked, No change there.
Boris shipped the Feb 28.

Feb 2 is long time.
I got a fat Prioity package in from Australia in Dec 23 took 10 days.

Yeah, apparently the packages got stuck in West Nassau, NY. To be honest, I have no idea where that is. But it seems that search effort unearthed the misplaced packages, just as I was ready to send you new ones which (in the meantime) arrived to NY stock.

Thank you for the patience, and I hope you get your packages shortly.

There is a Nassau County in NY.  It's on Long Island.   I've lived in Nassau County my entire life.  Never heard the term "West Nassau".

But apparently it exists.....
A google search shows a post office by the name "Western Nassau".   It's in Garden City, Nassau County, LI.   Not far from me.  Perhaps I'll pick it up and give it a test listen?       :lol:        :thumb:

John, you are correct, Western, not West... could be just a PO name  :scratch:

Garden City... that's where I became naturalized citizen... fond memories...  :)

Funny ways the packages move... last time when the materials were shipped from US to Serbia, they ended up being stuck in Turkey... it's a 3 hours, two countires, overshoot by plane (they literally had to fly over Serbia, then Bulgaria, to get to Turkey)  :duh: :scratch:  Shipping is not even that expensive, considering what's going on.

Very nice little piece from Print packaging to the form factor.
Well done and classy subdued looking !!
It sounds well.......... very nice too.  :thumb:

It will compete very well at it's retail price of $400 for sure. I have had a lot of Phono's through here.
Appreciate the deeep switches!

Get the word out. :green:
Bravo! Well done to Boris!!

1 minute into listening to the Phono-2 compared to my Phono-1 ACLE unit.
Big improvement in bass output which is what my system was lacking.
A full review will come in a few day’s as the cops where just here yesterday for a noise complaint.
Damn, I hate that.

The Phono-2 was packed to perfection. The unit looks beautiful and the silk screening is perfect.
Very easy to read the settings. The phono-2 arrived with the exact settings I asked for.
Can't wait to get some time in with the Phono-2.
I’ll be back.

It's a hassle living close to neighbors and being an audiophile. They call the cops about 4 times a year.
The cop that came yesterday was an audiophile, to my luck. He didn't give me any shit.

Do not let the price fool you! We have said that before. Very competitive to units costing much much more.
Boris nailed it very nice with these upgrades he added, gold board, beefed up 16 Caps PS and the dip switches,
cosmetics to match the quality. Oh we have a Ground lug too.
I'm a fan :thumb:

A lot of listening the last 4 days.
This is a very nicely made, of course great sounding, capable let me say easy to use Phono pre.
As was the Original ACLE unit I had which I didn't compare to.
The dip switches with custom if needed sockets, and 70 db gain is more than you will ever need to run any Cartridge. I would suspect any high end cartridge to sound great with it.
No need for Stepup transformers. I got away from trannies with all the wire flipping and  re-positioning the units to keep them quiet.

On a Heed Quasar I had the stepup did not help the sound at all. So everyone's equipment will be different.

The Vista 2 used with my Clear Audio Emotion CMB carbon, Satisfy arm, Phoenix PS, a AT33PTG II (.30 output), into a Rogue Cronus Magnum.
Settings changed, to now 100  47ohms resistance,  65 db gain, slow  fast rolloff filter.

I would not hesitate to recommend it. I think it is quite nice.

Add a couple Albums in particular: Just super having it all.
Sade >Promise
Grover Washington >Wiinelight

I have no neighbors to worry about! :duh:

Thank you for the feedback Den and Steve!

Den - that is a nice set of equipment that you have! I don't think I have ever set up Phono-1 to more than 65dB. 70dB (gain of more than 3100 times) is more than enough... even though that is not the limit: by using internal sockets, the gain can go even higher.

Thanks again!
Title: Re: Phono 2 feedback
Post by: MaxCast on 15 Apr 2017, 12:43 am
Thanks for the feedback, guys.  Been seriously thinking about getting a Phono 2 (got a acle).

Just so I have it straight in my mind, how does one use the dip switches?
Title: Re: Phono 2 feedback
Post by: bacobits1 on 15 Apr 2017, 12:59 am
Dip switches are used for the gain setting and resistance , and low filter settings. Take a look at the site descriptions it tells all.

http://www.vista-audio.com/products/phono-2/index.htm

 I find it's a balance of gain with whatever pre/ amp that is in front of the Phono any phono preamp.
Things get real agressive quickly after 60 db gain. The balance of selfnoise or amp pre noise. There is none here. Extremely quiet.
I go a bit to 65 because it is fine and the volume knob is close to the digital setting when played. I don't need a blast mistake going to digital. I should cut it back to 60 db.

Now on the Redgum (scares me  :lol:) it remembers what volume was previously set at on a particular input when selected. It will return to the last setting.
 Slick!


Title: Re: Phono 2 feedback
Post by: WireNut on 15 Apr 2017, 02:28 am
I love the fact that Boris is keeping a data base of optimal cartridge settings.
It keeps the guess work out of my next cartridge upgrade from my current 2M Blue.

Hi Boris,

 I'd like to load my ortofon 2m Blue MM cart at 34.5k.
I believe this would need to be done internally.

What do I need to do?

Vista Audio Phono-2 review.

I’m really enjoying my new Vista Audio Phono-2 MM/MC phono stage.
From the first track of my favorite LP I’ve been glued to my system.
Comparing the Phono-2 to my Phono-1 ACLE unit the bass, both mid/lower octaves are more deep, fast, and powerful. A definite upgrade from the Phono-1.

Midrange is also much better then the Phono-1. Goose bumps are popping up all over me.  Treble is detailed but never harsh. Very very good. I’m happy.
 
The Phono-2 has many external loading options that are available via DIP switches on the bottom of the unit for both MC/MM cartridges.

At the time of my purchase the Phono-2 did not come with a manual. A pdf file on Vista’s site for downloading would be great.
Without a manual, I find setting the internal loading options are not an option for me.

Sound quality of the Vista Phono-2 is very very good. As a matter of fact, it’s better then my previous Counterpoint SA-3 preamps phono stage, Pass Labs DIY pearl-2
and my integrated preamps phono stage. At the low asking price of the phono-2 it’s a fantastic buy.

To set the resistance to something other than the supplied settings you would set all the dip switches in the off position and the put the chosen resistors in the R11 and 12 slots just like on the Phono 1 Mk II. I found instructions on website.

Use this calculator to know what to buy to get the value  you want.  To get to 34.5 kohm you would need 130 kohm resistors.

I would have never quested for a 34.5 kohm load I would use 130kohm resistors :scratch:.

Post by: JackD on 16 May 2017, 11:23 pm
That's using the assumption that all off leaves it at 47 k as with the  Phono I.  If all off is in fact zero the just get the resistor equal to the load you want. I haven't looked at all the switch combos so don't know if you can get close that way.

Yes.  Then account for the value of your TT's wiring plus 50 pf for the unit itself.

I tried measuring the capacitance of my tonearm wiring and interconnects with a DMM just yesterday but my test failed :scratch:.
Meter set to caps, removed head shell and set aside, probed each head shell pin in the end of the tonearm while probing the hot and ground pins at
the end of each interconnect. No luck trying that, the DMM barely registered any thing  :dunno:.

Hi guys,

Sorry for being AWOL. I was on the road, and was not getting notifications on my email. Have to check out why. I just came back, and checked Vista circle. Please do not hesitate to use my email if you need prompt answers - that is something I check multiple times during the day, wherever I am!

Thank you Jack for helping!!

To answer the original question about 34.5k loading. Best thing to do is to move all DIP switches to the OFF position, and insert resistor 37.5k into R11 and R12 positions. There is internal default resistance of 1.5Mohm (1500 kohm) and the combination with 35.7k will yield 34.87kohm... close enough :)

The resisotr should be metal film, something like this one: https://www.digikey.com/product-detail/en/yageo/MFR-25FRF52-35K7/35.7KXTR-ND/15036

Closest you will get is to do what you've done and then disconnect TT's leads from Vista.  Then with cable as straight as possible measure the pin and shield of one of the RCA's.

Know problem Boris. I figured you were traveling.
When you say "Turn off all external switches" do you mean ALL loading, gain, and Low-Pass filters if I'm going to set the loading internally?
Or, can I set the loading internally, but use the external switches for gain and low pass filter's?
 
I'm trying to learn how to set up the phono-2 for future cartridge's.

Also, regarding C11 and C12 can you give me a cap series/brand/example for my reference?
My current cartridge suggest 150-300 Pf.

I've had no luck trying to measure my TT's tone arm and interconnect wiring so far. I'm obviously not checking it correctly. :scratch:.

This is a learning process for me. Thanks for your help.

Title: Re: Phono 2 feedback
Post by: JackD on 20 May 2017, 03:24 am
To change the loading internally just turn all the resistance switches to off and leave the rest as normal.  I suspect once you get a measurement for your tonearm cable and leads you will be within the parameters for capacitance without doing anything else.  To measure the cable it is easier with alligator clip leads but if you don't have them and only probes lay one of the cables out straight and put the positive lead from the DMM on the pin and the negative on the shield.  Don't let them touch each other or both parts.  If your TT is a vintage one with original leads it will be somewhere around 100 pf.  I measure almost a dozen JVC, Denon, Sanyo and Techinics tables and got between 90 and 125 pf on all of them.  That is why I ordered my Phono I Mk II with 50 pf instead of the standard.  Just FYI the resistance will make far more difference than the capacitance if you are even close.  The only cartridge I ever put any effort in to capacitance loading with was Felix's beloved Shure m97xe and I found it dead sounding at any setting.  Also make sure you meter is reading pf and not nf.
Title: Re: Phono 2 feedback
Post by: Audiovista on 20 May 2017, 07:48 am
Thanks for understanding Steve! Jack is correct, only loading switches need to be OFF, gain and filtration still need to be set as required. I should have been clearer in my post (darn jet lag).

What instrument are you using to measure cable capacitance? Many standard DMMs cannot measure low capacitances accurately. They may use 1kHz frequency for measurements, and for the cables 10kHz or higher will be better. I have just ordered a very inexpensive RLC meter to test, will let you know how it works when I receive it (I do not expect miracles, intended use is just for quick incoming inspection of power transformers).

You are measuring cables only, right? Cartridge is disconnected?

I have just ordered a very inexpensive RLC meter to test, will let you know how it works when I receive it (I do not expect miracles, intended use is just for quick incoming inspection of power transformers).

You are measuring cables only, right? Cartridge is disconnected?


 Thank you both for all this great info  :thumb:. I should have stayed in electronics in high school  :duh:.
My meter is a Southwire 10040N. I just read It will only check capacitance in auto range from nF and uF.

 Later today I’m going to make some test leads with clips and I’ll try and see if I can get a measurement in nF doing what Jack suggest.
If I can get a stable reading I’ll convert the numbers to pF. It's worth a try. I have to do something in my retirement :D.

 I’m checking my table’s capacitance with the cartridge disconnected and with the power off.

I checked the specs of your DMM (http://www.southwiretools.com/tools/file.get.do?file_id=244).

Minimum range is 40nF with 10pF resolution (0.01nF), ±5% and ±7 digits accuracy ... not great for what you want to do.

For example, if the actual capacitance is 0.10nF (100pF), the DMM can display any value between 0.03 and 0.17nF (that's the ±7 digits part which becomes the most critical for those low values).

Hi everyone, we are having a problem with web hosting service, something got messed up with Vista's site during service upgrade (Verty site is using the same service buf it is not affected). I hope to resolve the issue within couple of days.

All is good with Vista, we are all well and busy!

I ordered the Vista Audio Phono 2 a few days ago. A little frustrated because after the payment, I have sent 2 emails to Verty Audio to verify they received the payment as well as spec information on the turntable, cartridge and pre-amp. I have not received an email back, has anyone else experienced this when ordering a product from them?
Title: Re: Phono 2 feedback
Post by: Audiovista on 27 Jun 2017, 08:55 pm
Hi Rick,

Thank you for the order. I checked with Verty. Apparently they received PayPal notification yesterday evening and your last email with preamp info about two hours ago. The input impedance will not have any adverse effects on the preamp operation. Your Phono-2 is ready to ship. I think that Phono-2 will be set for your cartridge. The optimization is always done with Phono-1, but not with with Phono-2 as it is easy to set with the DIP switches.

Thanks again,
Boris

Boris, Thanks for the update. Sorry I seemed a little worried. I didn't realize it took so long for the paypal payment to go through. I had sent it 2 days ago, and sent an email the same day asking for payment verification. I then sent a 2nd email today because I hadn't heard back and was afraid the paypal transaction had an issue. Thanks for your quick response. I can't wait to get the phono 2! Rick

Hi Rick,

You are very welcome. It is unusual for PP to send confirmations late - I reviewed it and you sent payment on June 23, and Verty received notification on June 27 (I sent you screenshot of the PP notice by email). Usually it's a matter of minutes, and not days. We all try to reply to emails promptly, sometimes it takes bit longer (if we need to collect information), but this time it was glitch outside of our control.

Good news is that your preamp is in the mail and I am looking forward to your feedback.

Thank you for your patience!
Boris

Would the Vista Phono 2 benefit from a linear power supply?  The label says 12VAC so does that mean a 15V DC LPSU?
Title: Re: Phono 2 feedback
Post by: bacobits1 on 25 Jul 2017, 12:11 am
It would have to be 12v AC as  labeled
NO DC linear power supply!!!
I do not think there would be any benifit to an AC linear power supply.
Quite dynamic and quiet as is.

Boris I'm sure will answer.

Thanks Bacobits, I appreciate the answer. 

I own a DSpeaker Antimode 2.0 and it can run 9VAC or 12VDC.  By using a quality 12VDC linear PSU the dynamics are improved along with a lower noise floor.  I also like that there is no switching PSU in the audio chain to add any noise.  The Phono 2 may be designed so a linear PSU does not improve its performance.
Title: Re: Phono 2 feedback
Post by: bacobits1 on 25 Jul 2017, 12:29 am
I never seen any device that can run both. Do you throw a switch?
But yes usually a LPS has that effect.
Did you purchase a Visa?
It is quite the performer! But I'm a fan.
I also have other phonos.

No the plug in the back is labeled 9VAC / 12VDC and both work.  Not sure how it is done internally in the DSpeaker.

I did not answer your initial question if I own a Vista Phono 2.  I have been lurking so far and read the reviews here as they started to roll in.

I have a very good built in phono board in my Spread Spectrum Technology Ambrosia 2 preamp.  The only downside is the MC loading is fixed at 1000 ohms.  The MM input with a MC step up is sublime. 

I was thinking a Vista 2 would be a make a nice backup.  However, I think I already have a superb phono and would I be better served with a tube phono stage because that is different then what I have and use now? 
Title: Re: Phono 2 feedback
Post by: bacobits1 on 25 Jul 2017, 12:55 am
Only you can answer if and how much different it may be.
Tubes can cause some noise. With a step up it's all a balance.
All trial and error what works well.
That's why there is so much on the used market.
But that's ok I'll pickup the pieces!

System synergy and personal tastes have so much to do with the choices we make. 

The only way I can gauge success (after all is said and done) is if a component lands and stays in my system for an extended period of time. 

Is the Vista 2 your primary phono stage now? 
Title: Re: Phono 2 feedback
Post by: bacobits1 on 25 Jul 2017, 01:07 am
I switch between an iFi phono 2 with a SBooster LPS and the Vista.
A bit different flavor between the Two.
I have had a lot of phonos here too, many over a 3 year period. Some step-ups too nothing outrageous cost wise. All used.

Title: Re: Phono 2 feedback
Post by: Audiovista on 25 Jul 2017, 02:26 pm
Good discussion!

To quickly address the power supply question: Phono-1 and Phono-2 require AC voltage for the power supply. 12VAC is optimal, 9VAC will work, but not great - there will be loss of dynamic headroom (and probably more) but the preamps will not be damaged.

DC input is not supported. If a 12VDC power supply is accidentally used, there will be no sound, but the unit will not get damaged.

The wallwart supply that comes with the preamps is properly overrated... by about 400% (:D). I do not suggest spending money on different transformers. Extra money will be much better spent on good interconnects (t/t to preamp). This is something that I keep experimenting with... trying to understand which construction sounds better and why, which measured parameters matter (and why) and how to simulate external noises affecting cables and cartridges... there is no end to it...  :duh:

Hello all. I wanted to give my initial impressions of the phono 2, which i just received in the mail. It's been several months since i have had the phono 1 in my bedroom system. I have a microzotl2 as a preamp, which feeds my JWN 6V6 amp at 12 wpc or thereabouts. Source is the thorens 125mkII with the denon 301mkII.  Speakers are high output omegas. I decided to spring for the phono 2 after reading about its increased bass response.

The Vista audio phono 2 is quite a step up from its sibling. if there was ever any lingering doubt as to whether or not i may want to spring for a subwoofer down the road, i have to say the phono 2 opens up the bottom end considerably, so that won't be necessary.  in addition to a bigger soundstage and more precise yet musical imaging, my system sounds  a bit more refined in the upper register. And its not even broken in yet.

KUDOS to Boris for a great phono preamp.

Wanted to do a serious test on the bass today, so I cleaned my copy of Ray Brown and Laurindo Almeida, Moonlight Serenade. It's one of those Jeton recordings, direct to disc live in the studio in Germany. There's this one section where Brown solos with a bow. Holy Crap! My system now nails it.

Further reflections. Thinking on the subject of bass, I decided to switch out my Thorens for the VPI. I had replaced the stock head shell on the thorens some time ago, and that tightened up the bass considerably, but the bass through the scout in my main system is awesome, so why not switch?

OH Yeah. Not only does the phono 2 scale up with ease, but there is even more bass, as i had imagined, and even more refinement in the midrange and upper register. Think I will keep the scout in the bedroom for a while.

I can't believe there haven't been any new posts here for over 3 months! I'd like to add my voice to all those who've been praising the Vista Phono 2. It's been in my system since August and I couldn't be happier. I never tried any of the Phono 1 iterations so can't compare them, but the Phono 2 is definitely a winner. Smooth, accurate, shows me immediately the effect of any changes in cables, VTA, VTF, etc. Just quietly (very quietly!) and competently goes about its job without drawing attention to itself. And with so much versatility in setting loading and gain, it should see me through any cartridge upgrades for a very long time.

My thanks to all the early adopters who gave positive reports and helped me make my decision to buy one. And special thanks to Boris for designing and building such a great, affordable phono preamp (and just being an all around stand-up guy).

Dampening the case? Don't be absurd. It's not big enough to cause any vibrato.
Got it on your SUB? Again, you don't deserve owning it.

Thanks guys for the support, I am really humbled!   :notworthy:

I still plan to spend very high percentage of design time behind the drawing board and with prototypes hooked up to the instruments and in various listening setups. But I will give it little more time to think about more eye-pleasing enclosures, so you do not need to hide Vista stuff when guests come for dinner  :D

You may have seen what I've done with packaging of the Phono-1/-2: it took me a little time but I think the new package is protecting the units well, and it's not a total sore to the eyes. Probably some of this stuff is easier to outsource to experts, but I am such a big fan of vertical integration that I find it difficult to relinquish control. I prefer to pow-wow with my inner circle of trusted associates and friends, to have complete understanding of every process. Some people call me detail-oriented, the more honest ones just say that I'm PITA and they are probably right.  :dunno:  As long as we make stuff that I can proudly stand behind, all is good.

Hi Borris, Glad to see all is well with you. So now that the Phono 2 is a big hit, are you gonna discontinue the phono 1? It's only a $100 difference. If not, then maybe, bring it up to the phono 2 level, but leave out the dip switches. I guess you already have sockets for resistive and capacitance on the phono 1, just add the way to change gain and charge $50 less for same sound but no adjustments. Just an idea.

Also, what speakers are you using to power your Spark? Thanks for the info.

Ray Bronk
Title: Re: Phono 2 feedback
Post by: Audiovista on 27 Dec 2017, 05:56 pm
Thanks Ray!

There are no plans to discontinue Phono-1. It is still a viable option for people having multiple turntable setups or dual cartridges (several customers bought two, some even three Phono-1's). Other than more involved gain and load setting procedure (http://www.vistaaudio.com/products/phono-1mkII/settings.htm) there is not that much difference between the two preamps.

As for the Spark, it just made the "Best of 2017" list on Part Time Audiophile site (https://parttimeaudiophile.com/2017/12/25/the-part-time-audiophile-guide-to-the-best-hi-fi-gear-of-2017/). As the list is sorted by price, Spark is all the way down. I have to say that John R. actually purchased the Spark for the review (before the review).

Spark loves Omegas (https://omegaloudspeakers.com/), it's a match made in heaven. Truth to be told, one can't go wrong with Louis's designs. I currently use Spark in my office with the new Dayens Grande Nano. An amazing desktop speaker.

Hey Steve!

Thanks for asking! There are several projects on the drawing board, but I'm still not sure which one will be the first to see light of day. The two developments that occupy me most are Phono-3 (hey, you guessed the name  :lol:) and Spark-T (a version of Spark with tubes). I made a tube buffer few years ago, but was not happy with the final result (I was ambitious with the goals and concept, measurements were great, but sound fell short of my expectations). I will be working on a new buffer design for my OEM partners at Symbol Audio, will implement what I learned last time; the bonus is that it will pair with the custom active preamp of my design, followed by Spark, so I have the electronics chain under control. 

Should be a fun year!

Hi Boris,

I like the idea of a Spark-T.
Have you givin any thought of a Spark-T as just a line stage without the amp section,or an option to bypass the amp?
Just a small hi quality preamp with 1-2 inputs and 1 set of outputs?
Title: Re: Phono 2 feedback
Post by: Audiovista on 4 Jan 2018, 11:37 am
Hey Steve,

Not sure how I missed this post, it must be that notification had problems progressing to my mailbox.

I am working on a separate preamp with 3 inputs, one of which is phono. It's custom designed to work with Spark power amplifier in analog setup (it has a nice feature to turn on turntable when Phono input is selected). First listening tests are promising, but it's still too early to tell if this will stay a custom product or it will progress to a fully released production model.
