Title: IDA-8 ($995) features and spec
Post by: rustydoglim on 19 May 2015, 11:27 am
Following in a long tradition of audio excellence, the NuPrime IDA-8 combines the substance and warmth of an Ultra-Linear Class A Module (ULCAM) in the preamp stage with the extraordinary speed of NuPrime’s  proprietary Class-D power for a spacious, transparent, dynamic  and luxuriously textured soundstage. The IDA-8’s exemplary distortion numbers (THD+N=0.005% and SNR=-130dB) account for the unit’s peerless clarity.  With the inclusion of a DAC that decodes USB PCM 384 and DSD256 in addition to a 100Wx2@8Ohm (180Wx2@4 Ohm) power amp in a 8.5” wide chassis, the NuPrime IDA-8 is truly a technological milestone
 
The IDA-8’s low noise floor is further complimented by an innovative volume control based on a thin-film resistor design that positions a single resistor in the signal path for each volume setting. Volume changes occur in 99 precise 0.5dB increments for each input’s individually adjustable volume level. Precise level matching is a breeze, as is the user’s ability to make comparisons of music sources.

By utilizing discrete components in NuPrime’s ULCAM circuit, the signal can be fine tuned to reduce noise and provide maximum power.

The NuPrime amp circuit improves on traditional class-D design by using a self-oscillating circuit to generate pulse-width modulation. The amplifier switches at a frequency of 600kHz, well beyond the compact disc’s 44.1kHz sampling rate. Most class-D amps switch at 300kHz or lower.  In addition, NuPrime’s SRC IC chip provides FPGA processing for ultra-low jitter and distortion rates.  Completing the ensemble is NuPrime's new linear power supply with its high-efficiency toroidal transformer for reduced high-frequency noise and strengthened low-frequency performance.  The damping effect of the NuPrime isolation feet (patent pending) absorbs and cancels vibrations that degrade audio performance. The overall result is unprecedented transient speed and an almost shocking level of dynamic impact.

The IDA-8 achieves Total Harmonic Distortion + Noise (THD+N) levels of less than 0.005% while achieving a system efficiency of up to 93%. The IDA-8's frequency response to 50 kHz elevates vocals into emotional experiences; similarly, instrumental upper registers mimic a live performance’s shimmering heights .

The IDA-8's features and specifications have few equals. Just one audition will convince you that the IDA-8’s performance and sophisticated styling are rarely duplicated at any price point.

The pricing is not a typo, it is $995. 
Shipping in June.
Bluetooth aptX dongle (digital in) is included.
I recommend all audiophiles even if you already have an integrated, buy one.  For the price of a few nice dinners for two, you will be truly surprised by what this little monster can do.  Time to sell all your other amps (except IDA-16 and Ref 20).

Interestingly enough, at this price point, this model is even the "go to" choice, for those in the market for an Audiophile, High End, Simple, Preamp/DAC.

If you review the feature set, and the specs, few come close.   :thumb:

Is the "Individually adjustable volume on each input for precise level matching of sources" a limited trim range, or can it be used to set the analog input to 99% or 100% for use as an HT Bypass input?

Rusty Dog,

Would the IDA-16 be considered a better performer than the IDA-8 or since the 8 is newer it may be better - if you don't need more than 100 W of power?
Title: Re: IDA-8 ($995) features and spec
Post by: rustydoglim on 19 May 2015, 09:15 pm
We are working on a new remote (simple credit card size) for IDA-8, DAC-10H and IDA-16. IDA-16 will continue to have the original big wand remote (the card size remote is extra).  Some people complains about the wand remote being too big or not sensitive enough. So we decided to make another remote.

IDA-8 and IDA-16 have two different amp designs. Honestly we can't say one is better than the other. They are just different approach in the respective product's philosophy. 
IDA-16 aims for very detail and balance.
IDA-8 was designed to have richness in sound (technically this means even harmonic, but it is not that simple).   This is not the same as distortion in tube amp. IDA-8 actually have lower THD+N (incredible 0.005%) than IDA-16 but anything below 0.1% THD+N is hardly noticeable.

We are now getting so good as manipulating the amp design (proud to say that we are still one of the rarest high-end company to design our own class-D amp) that we can come up with anything that sounded like tube or class A amp but without the drawback. 

So IDA-8 sounded like a very high-end class A amp with the dynamic and speed of class D.

Ok, hard decision.  I say if you don't need more than 100W, get IDA-8.

Steve

Yes.  Each input remembers the Volume Control setting from the last use.  So you would simply set the "analog" RCA inputs to full volume for HT.

Other than power, what makes the IDA-16 worth $1600 more than the IDA-8 ?
Title: Re: IDA-8 ($995) features and spec

One difference I know of is that the IDA-16 has more digital inputs than the IDA-8.

I have to say that I am amazed at this product.  A mini (but not upgradeable) Devialet.

Which Nuprime Dac is comparable to the dac in the IDA-8?
Does it use the SABRE dac like the Dac 10?

While Rustydoglim is the one to answer most of these questions definitively, I can offer some info:

1) It is my impression that the unit is from Taiwan

2) Key differences between the IDA-8 and IDA-16 are;

IDA-16 Amp has 2 x the power output and would certainly be the choice for larger systems, and less effcient speakers.  I have used the IDA-16 with speakers that LOVE current, and the 200wpc was displaying WELL ABOVE the rated power. 

Different DAC chipset.  While the reality of the situation is ALWAYS implementation, the IDA-16 has the ESS SABRE DAC chipset and the IDA-8 has another brand.  That said, most know that the ESS SABRE has some of the lowest jitter of any chip set, but if you viewed the specs to the IDA-8 you likely noticed a S/N, that was Out of this World.

The IDA-16, has more inputs, meaning it would be better for more complex and larger systems.

At this time, the IDA-8 is scheduled to have a smaller remote, while the IDA-16 currently has the octogonal wand.  This may change in the future.

At this time, the IDA-8 does not have a wireless network connection, so iPHONE control is not available.

NuPRIME is certainly "S-T-R-E-T-C-H-I-N-G" the limits of performance you can expect for your AudioPhile Dollar.

Post by: amatuerholic on 22 May 2015, 01:13 pm
Does the sub out have adjustable crossover or lpf?

I'd be beyond sold on the IDA-16 if it had that feature.  ::fingers crossed for future revisions::

It would certainly free up amplifier power if you had something else taking the brunt of the low-frequency amplification, instead of expecting the speakers to run full range.  I wonder how much extra it would cost to add that to an amplifier that does not already have a high-pass filter.

Not at this time. 

Most powered subs already have Low Pass Adjustability.

Hi Greg,

I don't see how, since to use the iPHONE/iPAD control function you need to be sending and receiving via a Wireless Network.

So I am simply going by that.  The IDA-8 is not connected to a Wireless Network.

IF. . .that control function can be performed via the Bluetooth dongle, then maybe so.

RustydogLim will have to address that possibility or available function.

 Thank You John, Yes I was thinking blue tooth not wifi. I know a lot of low quality name brand rcvrs. use blue tooth now for controlling functions. I have an application for that but don't want to use those brands.

IDA-8 has a custom digital port and comes bundled with a Bluetooth aptX dongle (digital in for best Bluetooth performance).  Later when the NuPrime multi-zone wireless receiver/streaming is available, it can be connected to this port. Obviously you can also connect Airport Express or other wireless receiver's optical output to IDA-8.

If you are talking about using iphone/ipad to control IDA-8 functions as a substitute to the supplied remote I would think it would require someone writing a app for it like with Xfinity cable and other companies that offer that feature.

According to the aptX® website, there are no Apple products with this codec, but there are many models from the other manufacturers like HTC, LG, Samsung, Sony, etc.  aptX® Phones (http://www.aptx.com/category/phones)

Interestingly, there is only one phone listed as having "aptX® Low Latency", the Vertu Constellation (starting at $5600)!

I'm pretty sure, any Bluetooth phone will work.

For that matter, if your laptop, computer, or iPAD has Bluetooth, that should also work.

I have used the NuFORCE BRT 100 which also has APT-X and it works find with any bluetooth enabled transmitter within range.

BTR-100 (http://www.aptx.com/product/nuforce-btr-100-bluetoothr-receiver)

The IDA-8 is going to be similar.

Yes, this is what I'm asking. Most of the name brand surround sound receivers offer this feature, I'd like to find a higher end 2 channel unit like this to do the same. John said he thinks it will work but it would be nice to know for sure. Rusty?

There's a difference between using Bluetooth technology to pass the audio signal from a phone, tablet or computer to the IDA-8 and NufPrime having an application for the phone, tablet or computer to control the IDA-8, e.g. control volume, switch inputs, change settins, etc. It clearly does the first but there is no indication of the second.

Let's see what Rusty says.

The Bluetooth connection is for streaming songs. The remote is for everything else. Wired connection will be ideal. Personally, I'm waiting to see if MQA can be streamed from my tablet through Tidal or if I need a new DAC.

The line (sub) out has 6V, i.e. 3X gain than the internal amp.  So that means you can crank up the sub without going full volume on your main speakers.

I think you are talking about an App that replace the remote and control the Input Selection, Volume and On Off.  That would require that we build WiFi into the Amp, or have some sort of firmware to decode bluetooth command for the control panel.  This will complicate the design and perhaps change the performance.  I don't see much benefit for an App to control the IDA-8.  Sure, extra convenient perhaps.

Thank You Rusty, you are correct.

The idea was finding a solution for using the system to power outside speakers in the summer and being able to control volume or source selection from a smart phone.

Not having to be in "line of site" of the amp to control these functions like with an IR remote would be nice. Not to mention not having to carry around a remote in your pocket along with your phone which one would probably already have with them.

You can get a home remote control hub which gets positioned in the house to have IR line of sight to your components (or not for your Bluetooth components), then relays the WiFi signal from your Android or IOS device to IR or Bluetooth commands.

There are quite a few of these devices available, including the Logitech Harmony Home Hub (http://myharmony.com/products/detail/home-hub/).

I have the Logitech hub in question.  When my 900 died under warranty and they had stopped making it, I was offered one of the hubs.

Does a great job operating my hidden components in my HT closet.

BUT, the hand held unit itself (it comes with a remote, or you can use an app on your choice of phones/tablets) does NOT have IR built into it.

So, if you have all your gear hidden, but your TV is in front of you... it can cause issues.

The following brief guide might help you decide between ST-10, IDA-8 and IDA-16
Sound characteristic - ST-10 has the perfect balanced for people who is looking for some texture, warmth and yet detail and resolution in an amp. It also has gripping control and bass. ST-10 is the best you can get before moving upward to Reference 20.
IDA-16 is very well balanced and detailed. For entry level high-end audio, IDA-16 is a good place to start and you won't easily run out of power.  It has everything you need, including a DAC with enough resolution and inputs that will not need any upgrade for  the foreseeable future.
IDA-8 sound characteristic is between ST-10 and IDA-16. If you have high efficiency speaker, or bookshelf speaker in a small listening room, this is the best integrated amp on the market. I don't think anything below $2K would be able to compete with IDA-8. At $995 that also include bluetooth aptX and DAC, it is as future proof as you can get.
If you are looking for a reason to upgrade your old mini component or outdated entry level audiophile system, IDA-8 gives you everything you need in one box.

Rusty, thank you for the short guide to choosing.  I just spoke with John to order an ST-10 based of this post and the review in TAS.

Could you answer a couple of additional questions on this product?

1.  the specs mention a WiFi (optional receiver) module, yet i cannot see any part of the IDA-8 where this feature would be currently used.  Can you explain what the WiFi module would be used for?

2.  You mentioned in another thread an upcoming DAC-8 based of the DAC/pre section of this product, is that still in the works?  if so, are you able share any more information on it at this time?

Thanks.

1. There is a free (and very good) bluetooth aptX dongle in the IDA-8 package that plugs into a USB-like port (it is not USB) at the back, we call that the digital port. If we release a WiFi receiver, it will be able to plug into the same port.  Obviously you can use Airport Express or other WiFi receiver and connect to analog or optical input too.

2. DAC-8 schedule is being pushed out for HA-8.  HA-8 is very similar to the headphone amp section of DAC-10H with 4 inputs and XLR, 3.5mm and 6.2mm outputs.  With many digital players and DACs out there, the market need a very powerful and flexible headphone amp.

Thanks.

Sorry to see the DAC-8 is being pushed out but certainly see and understand your reason for doing so.

The potential DAC-8 seems very appealing to me from a feature/options/potential price standpoint and i prefer its design over the DAC-10.  Likewise i'm sure the DAC-10 is the superior product in regards to function.

I am trying to decide on a front end for the ST-10.  Given the possibility of waiting for the DAC-8 release or picking up a DAC-10 (no need for headphone amp) or maybe even an IDA-8 and using the line outputs  what would you recommend for this situation - ProAc Response D2s/Harbeth HL5 speakers, small room and of course the ST-10 amp?

I am trying to decide on a front end for the ST-10.  Given the possibility of waiting for the DAC-8 release or picking up a DAC-10 (no need for headphone amp) or maybe even an IDA-8 and using the line outputs  what would you recommend for this situation - ProAc Response D2s/Harbeth HL5 speakers, small room and of course the ST-10 amp?

The delay is only a few months. You must have some sort of DAC or OPPO that you use now. Just hang in there for a few more months :)
There are more cool stuff coming. I will discuss with R&D and do some planning this week and get back to you guys.

Hi agdev01,

When we talked, I didn't think of it,  :scratch: but if you can get by with USB connection only, a good "temporary" solution, would be the uDSD (http://www.nuprimeaudio.com/index.php/pages/the-team/portable-dacs/udsd) for you.

At $179, and 2v output it could drive the ST-10 (coming soon) and give you a reasonably priced solution.

Not in the same league as the DAC-10 or DAC-8, but still far better than ANYTHING in that price range, and inexpensive enough to use until the DAC-8 is available.  Then you could either keep it, or take 60% of the price paid credit toward the DAC-8 when it is available, as a trade back.

Problem, solved.   :thumb:

I'm biased because I am using one, but I would give in and buy the DAC-10.  Also I would not recommend using the pre-outs on the IDA-8 to drive the ST-10. Their 6v output level would give you little to no range with the volume control. They are intended to be primarily used with a Sub.

IDA-8 will be shipping to distributors worldwide starting next Thursday or Friday.
USA customers would likely get their shipment first week of July. We are shipping to Indiana warehouse and then ship them out by FedEx ground.
Other countries would be getting their stocks around the same time too.

A few samples have been tested by distributors for a month already and we made some minor sound tuning for perfection and is going through final assembly and testing now.

If budget is not a concern, I still recommend DAC-10 to match ST-10 (to put it in perspective,mthe price difference between this and DAC-8 is like the price of five nice dinners for two but you get to enjoy it for many years).

The amps are going to leave the factory in Taiwan either 24th or 25th, delayed for a few days due to dumpling festival in Taiwan that we didn't anticipate.

Silver color will be delayed for another 2 weeks (we decided to provide all silver case instead of silver front panel so the additional aluminum anodization work caused the delay).

The pre-out gain is set to 3X as a standard configuration.  But if you want to set it to 1X or 2X, you have to custom order from the factory (which might take extra weeks of delay depending on whether there is new shipment to the distribution warehouse).

Looking at the tracking #'s for many of the Preorders I see them being delivered today or tomorrow.

If you get one and get it set up, SHARE your impressions.

WARNING!!!

ALL NuPRIME products come set at 230v, and for US use, the little switch on the BOTTOM, "must" be checked and set to 115v, or the unit will not play.

Can't wait to fire this thing up and see how it sounds.   :thumb:

Well I hate to say WOW!, but WOW!

Just quickly hooked this unit up to begin the burn in and it is immediately impressive.

First it is MUCH HEAVIER than expected.  This is ONE SOLID unit.

Fit, finish and build is excellent.  Even the binding posts stand out.

Now, this is NOT going in a real HIGH END system so I was not expecting miracles.

I had had the NuFORCE HAP-100 and the ST-100 powering it to this point and knew what it sounded like and its supposed limitations.  This is with some rather inexpensive EPISODE 700 $600 pr Stand Mount Speakers I use for Office/Bedroom/Small HT Systems.

(http://www.snapav.com/images/Product/large/ES-700-MON-6-BLK-A.jpg)

Set up was just seconds and the immediate LEAP in sound quality was "in your face" there.

Depth, Soundstage, Tone, Richness, and imaging were all RIGHT NOW better by a huge degree.  Even without what one might consider High End Speakers, I was hearing High End Sound.

These improvements were entirely using the BlueTooth dongle so, after burn-in I'll run a CDP directly into the DAC and see where we are.  :thumb:

I fired mine up yesterday, and I am super happy with the sound. Small package but heavy! Spartan looks. I used Audirvana from a Mac mini as source. Speakers are Avalon Arcus. This amp has more than enough power to make them sing in a medium sized room. Soundstage and depth are phenomenal out of the box. Drums, vocals, bass...all excellent. The built-in DAC is very high quality. I also used the iphone 6 to try the bluetooth connection, it worked seamlessly. I am completely sold! IDA-8 is replacing my tube pre+SS power amp combo and DAC. One big hurray for NuPrime designers!

How does the IDA-8 sound compare with the Ref9SEv3 amps?I am thinking of getting a second set up and considering the IDA-8.

Although, I doubt that anyone has done a direct comparison, some may be coming from the REF 9 to the IDA-8.

The REF 9 are hard to beat sound quality wise, and are among some of the best amps you can get. (especially the v3 SE versions)

That said, I do think you would hear a difference and that would be due to three primary elements:

1) The REF 9 is more powerful (335wpc vs 100wpc) and has 2 (one in each monoblock) power supplies

2) The IDA-8 has even order harmonics which are the harmonics which tube lovers find entrancing.

3) I think the IDA-8 also has a higher S/N ratio, so that might also be a player.

Which would sound better is likely going to be a personal choice (unless you have a large room and lower efficiency speakers that require the power)

I might submit, that one might like "both" sonics and find neither off putting, or better than the other.

I used to use a Son of AMPZILLA, which also had "tube like" sonic qualities, and REF 9 v3 SE monoblocs.  While I slightly preferred the REF 9 clarity, I liked both sonics and found fault with neither.

While the IDA-8 is an over achieving performer, it will not be as good as the DAC-10 and ST-10 combo.

It's strength and value, lies in its "price/performance", but the same applies to the DAC-10 and ST-10.  Recently reviewed in Absolute Sound and praised quite highly.

That said, you could easily call the IDA-8 HIGH END sonically, but not in price.

Seriously nothing else can compared to IDA-8 at this price.  We are so confident that if you find another brand and decided to buy it either by comparing the two or within two months, we will give you the refund.
It will become clear when those people who received them started to provide feedback.  We sold more than 200 units worldwide within two weeks.
So far all went out without incident except one guy who reported that the amp module is DOA, but we haven't had the chance to take a look. It could be due to shipping where something become lose.

As a follow up on my IDA-8 evaluation (I think everyone knows I am also a NuPRIME Dealer so just to disclose)

Well, after a lot of burn-in and Bluetooth use, I finally got a chance to connect a Denon Transport to the Coax Digital input to do some CD listening (16/44)

In assessing a set up one needs to realize that NO set up should make EVERYTHING sound good, since that would be "sugaring" the sound, which is a distortion.  That is, a great component will allow you to hear differences in recordings and files rather than all sounding the same, since these differences exist in the recordings.

A good component will also allow you to hear differences in your various components, set up, and room.

The point being, that I found these elements quite clear in the IDA-8.

After listening casually for the burn-in, and enjoying things like tonality, and spatiality, I got the chance to pop a CD on the transport, and hear some CD resolution cuts. 

Well, as expected the IDA-8 was quite the performer.  I very quickly discovered that I needed to adjust the speakers a bit to cure a couple small issues, that were NOW quite clear, but not as evident earlier.

I listened to a "mix-CD" that a friend had sent me to celebrate his 64th birthday.  You know old reflective tunes like "When I'm 64" by the Beatles, and "Old Man" by Neil Young.  Not stuff I listen to daily, but good enough show me that I needed to move speakers a bit and get my listening position just right.

Reminded me that early Beatles Stereo had the singers out of one speaker and most of the music out of the other.

Then I got into some more modern recordings and Elton John, Joni Mitchell, Jerry Garcia, Cat Stevens, and other artists had a strong center image.

The sound was pretty good and in some cases REALLY good, and that made me see (hear) how the recordings themselves, on a good system, will determine the quality of sound you hear.

Then I wanted to hear some of my Reference Recordings.  These are recordings, I have heard hundreds of times on hundreds of systems, so I know what they sound like, and or SHOULD sound like.  Cuts like "Keith Don't Go" by Nils Lofgren, and the Bass Solo Cut that is the Preamble to Amazing Grace, on the Live Bela Fleck CD played by Victor Wooten, as well as others.

These have harmonics, tonality, liveliness (as in LIVE RECORDING), soundstaging, imaging and many other qualities that tell you if your gear is giving you "all" the music.

I was pleasantly surprised at just how much of the Reference Tracks I was able to hear on such a modest system (under $1600 retail)  The Speakers were clearly the "weak point" so, you who have really good Monitors, are likely in for some really High Performance Listening Sessions.

Of particular note, was the ability of the IDA-8 to resolve and separate instruments, and their subtle detail.  Many, even high end amps congeal the sound into a mess of sonic soup, especially when pushed, and even with these modest speakers, the separation, deliniation, detail, and imaging was really UP THERE.  :thumb:

Also of note, was the BASS quality and quantity.  On the Victor Wooten cut, there are many runs, dynamic passages, and harmonic overtones, that some systems just gloss over.  I was happy to hear the foundation and detail of all those qualities.   :D

Early on in this amps Heritage these qualities were quite evident, and they are not only still there, but better than ever in this latest model.

Happy to say, this is a Home Run for NuPRIME.

By utilizing discrete components in NuPrime’s ULCAM circuit, the signal can be fine tuned to reduce noise and provide maximum power.

So, unlike the HAP 100 that uses IC chips?  The IDA-8's preamp section is discrete? 

This may turn out to be just what I had been looking for.  That took me by surprise.

I can't say about many other brands, but as far as NuPrime is concern, we try to make our products better and cheaper all the time. Other high-end brands are surviving by making fancy boxes more and more expensive utilizing third party class-d modules, we continue to innovate. So I can confidently make the general comment that IDA-8 amp will have no competition at this price point.

IDA-8 does up sampling and our bluetooth aptX dongle sends proprietary digital input to IDA-8 through a USB lookalike port (it is not USB) so we can ensure the highest quality for bluetooth and then up sample and decode.

But for people who wants to play with components, wait for DAC-8 or go with DAC-10 and ST-10.

Have not heard the DIA100 but I know my old buddy Corey Greenburg used to like it.

I think it has a "passive" Volume Control, so you might find the stepped, thin film ladder Volume Control an interesting change.

I might also think that your Altec 601c would love the "even order" harmonics of the IDA-8, and if you like that type of "sonic" then it could be a match made in heaven.  What you then have, is a more "tube-like" sound quality, BUT. . with exceptional detail and tight dynamic and deep bass.

Plain, simple looking, but the sound was exceptional.  When we first plugged them in we weren't expecting too much and Tommy remained a little self deprecating, then we played some cuts.  WOW!

I would be very interested in what people think of the blue tooth regarding sound quality compared to a direct connection.

I think one of these is in my friends and my future as this is perfect for his cabin and I'm moving my main stereo to a new location and simplifying my great room system. Depending on what the dac sounds like will be a factor for me as that is one component I like to be able to change as the technology advances. To this point I have favored nos dacs for their organic qualities but am open to new dacs that can portray a live like sound quality whatever the technology might be.

I apologize if this has been covered but I don't recall whether a unity gain or bypass has been employed on this unit?

Is the "Individually adjustable volume on each input for precise level matching of sources" a limited trim range, or can it be used to set the analog input to 99% or 100% for use as an HT Bypass input?

And the response was:

Yes.  Each input remembers the Volume Control setting from the last use.  So you would simply set the "analog" RCA inputs to full volume for HT.

Just picked up my unit from our Local agent Joel via Achim. We did a little listening to the one that Joel has had for a while and I was very impressed with what I heard, tried the Blue tooth via my phone and brought a smile to my face!

I will report back next week with a more detailed report.

I can't say about many other brands, but as far as NuPrime is concern, we try to make our products better and cheaper all the time. Other high-end brands are surviving by making fancy boxes more and more expensive utilizing third party class-d modules, we continue to innovate. So I can confidently make the general comment that IDA-8 amp will have no competition at this price point.

IDA-8 does up sampling and our bluetooth aptX dongle sends proprietary digital input to IDA-8 through a USB lookalike port (it is not USB) so we can ensure the highest quality for bluetooth and then up sample and decode.

But for people who wants to play with components, wait for DAC-8 or go with DAC-10 and ST-10.

Thanks.  I made a mistake in my previous post.  I meant to state i have the nuforce dda100 not the dia100 which is an acurus product.  Sorry for the confusion.  So, relatively, sound quality is better with bt than usb with the ida8?

Got it.

In that case, yes, I have heard both, and while the DDA-100 was a WONDERFUL performer and value, the IDA-8 is in a totally different league, just a few notches down from the IDA-16.

The IDA-8 is also far quieter, (130db S/N or better) than the DDA-100.

Hi Greg,

I have some MPS songs that I enjoy and downloaded them from MP3 Downloader and streamed them direct from my phone to the IDA-8
I know MP3 is not the best quality to listen to, but the fun factor was un-measureable! Audio from my dedicated Hi res server is very, very good and at this price there is no competition.

Hey Rustydoglim, I have a question about the analog input on the IDA-8. Is this port specifically tuned to only use a cd player as an input device? I have tried hooking my cable box up to it which produces an awful hum (no hum with my current amp, though, a cambridge audio ar30) and also my Schiit Bifrost which produces a significant crackling in the right channel when certain tracks with a high dynamic range are played. It works fine with a cd player. I have tested the same tracks with other amps, cables, etc, and made sure there are no ground looping problems. I was hoping to use the analog input for tv (it's my only option with the cable box i have) and optical for music. Any suggestions?

This is a bummer because it really sounds great otherwise, I don't want to have to return or sell it.

I tried three different Dacs into the analog inputs of the IDA-8 with no issues whatsoever.  They were the DAC-10, W4S DAC-2 and the Peachtree DAC-ITx.  Also used the Visa Phono I MkII set at 60 db and again no issue.  As to the cable box, mixing cable tv and audio is always a recipe for frustration.  Sometimes it works and sometimes it doesn't.  Not necessarily the Nuprimes fault or the Cambridge's credit, just luck of the draw.  Can you take the audio signal from the TV itself either coax or optical and take the box out of the equation.

How did the other Dacs compare to the internal fav in your IDA-8?
Title: Re: IDA-8 ($995) features and spec
Post by: JackD on 30 Jul 2015, 12:53 am
To "my ears" the DAC-10 was clearly superior, as would be expected.  The Dac in the 8 and the Peachtree sound the most similar.  They both are based on a "similar" chip from different ESS families, the 9010 and the 9023.  The W4S's edge would come as the result of it's large dedicated power supply just like the DAC-10. As all four DAC's are based on a variant of the ESS family they all have similarities.  There differences are more based  on the power supplies and front ends.  The DAC-10 and the IDA-16 are both based on the same chip and based on what I have been told the 10 wins due to the dedicated power supply.  Again just my opinion and others including Jason and John may offer different ones.

If your system is still the same as the one listed in your "systems" profile, your best move would be swapping the DAC-10 for the Benchmark. If otherwise then disregard.

I can't answer with the expertise of Rustydoglim, but have a couple thoughts for you.

1) Cable box connections are notorious for "humming", since they are seldom well grounded.  AVR's are designed to shield against this, thus your not hearing it with your Cambridge.  An easy fix is to use the "optical" output of your cable box to the IDA-8 so that the hum cannot be transmitted to it.  It is not the IDA-8 introducing the hum,(ground loop) it is just producing it from the source.

2) You should then be able to run your CDP via the COAX digital no problem.

If you want to test to see if it is your cable box, simply hook everything up so you clearly hear the hum, go to the wall and disconnect the "CABLE" coming from the wall, and as soon as it is disconnected the hum will stop.

Other potential fixes:

1) Cheater Plugs (NOT RECOMMENDED)
2) Various devices known as "hum busters", can work, but if the above suggestions (1&2) work then that is your best solution.

My first post on the forum and with Rodney and Stuart a proud owner of the first shipments to SA.  I gave feedback on our local forum which I copy+paste and just updated a section to indicate not local forum reference.

*** From SA AVForums ***
As one of the early birders and not a lot of time before I had to leave the country again... however could compare it with some of the amps I have lying around and a few speakers in the room.  On the Sunday I woke at 03:30 to start listening.  However, my personal impressions noted.  Link to the product http://www.nuprimeaudio.com/index.php/pages/pages-overview/integrated-amps/ida-8 (http://www.nuprimeaudio.com/index.php/pages/pages-overview/integrated-amps/ida-8)

Achim (13Hof) brought an early bird option for 10 willing to 'jump in the cold water'.  No idea how the product sounds and will to gamble.

Some background first on what I owned before and although not a side by side comparison.  My top of the line combination that I owned was B&W 802N being fed by 31.5 Mark Levinson Transport. This fed into a ML 30.6 DAC and then finally into a ML 336 power amp.  Transparent speaker cables and Madrigal Gel balanced cables straight through the chain.

I did some homework before the option was placed on the table and I had some reservation as I realised that NuPrime is basically split from the NuForce brand which will focus on the higher end market.  I tried the NuForce Reference 9 V3 Special Edition once... and I did NOT LIKE IT!!  I read a review on the NuForce and the reviewer said he sold his Mark Levinson 33H's (which I was drooling for) and replaced it with the NuForce.  Even the wife came and told me the NuForce had no soul.  So when the option came, and I wanted to be one of the early birds, I pulled the trigger.

The shipment arrived in SA quicker than expected and I went to collect mine from Joel.  A very standard brown box with a plastic carry handle protecting the actual commercial presentation.  First impressions was the weight.  The small form factor weighs much more that you think.  Hopefully this means lots of quality components and a good PSU inline.  It is noted as class A/D so hopefully some copper for control. I will still open it sometime down the line.  The unit is very small and I opted for a black unit which is really a good looking device.  It is less and a 30cm ruler wide and looks lost on top of my Emotiva XPA-2.  It was time to connect and see what is on the menu.

The speaker output terminals are fairly close to each other but they look the part.  Solid metal, no plastic. My source I used is a Logitech Squeezebox and connected this using 3 methods.  Analog, Optical and Coax.  This allowed me to swop between a single source with external DAC (Logitech) and the internal DAC on both optical and coax.  Before I switch on, I did make sure that is was for local voltage.  Box was sealed and was set at 240V... all good!

The first set of speakers that I tried was a set of B&W CDM1NT. (8 ohm nominal) This is the older generation and I still think they are underrated and some people seem to dislike 'yellow cones' :).  Squeezebox was at 100% volume (no bits are stripped on the volume control) and I played at low volume on the NuPrime a while without listening to warm up to normal operating temperature.  After a few hours I sat down and played one of my reference tracks.  Religions - Carmen Cuesta http://www.amazon.com/dp/B0015ELN06/ref=dm_ws_tlw_trk11 (http://www.amazon.com/dp/B0015ELN06/ref=dm_ws_tlw_trk11).  I know the bottom end and the voice coming in is riveting. I up the volume to 80 and pressed play.  I did not expect the control of the NuPrime gave to me in spades and buckets. Just before that I was playing through the Emotiva XPA-2 https://emotiva.com/products/amplifiers/xpa-2 (https://emotiva.com/products/amplifiers/xpa-2) which is a 300W/channel into 8 ohms.  Don't get me wrong... Emotiva is great but this little box of tricks that has a DAC and a preamp in... just took me by surprise and had me wanting for more of my reference list.  Between the Sheets (Fourplay) track called Chant https://www.youtube.com/watch?v=xYZ5qriC7M8 (https://www.youtube.com/watch?v=xYZ5qriC7M8) has well controlled drums and percussion sounded more controlled and the noise floor is non-existent. Now I know what some reviewers say about 'playing against a black veil'.  Charles (Placebo on the forum - South Africa) came for a collection and I had to sit him down with a nice black coffee and asked him for his feedback.  The B&W CDM1NT's were standing (dwarfed by) next to the Polk Audio RTiA9 and as soon as the first track were played, Charles could not believe the base and control from the bookshelves.  He asked me if it was the small ones (Yellow Cones) and not the large floorstanders.  My son 15 years old and critical of my selection is more in the DJ scene and doing well.  Opened for Locnville and DJ Phonic (have to thrown that in as a proud dad) comments were verbatim... 'I am not normally impressed. But I am now'.

When a pair of Sonus Faber Cremona Auditors became available, and I had the NuPrime IDA-8, I thought... man this could be a combination.  I went to collect the SF's, replaced the B&W's and then, without sounding like a poet, I was in audio nirvana.  The SF's are nominal 4 ohms; so it requires a bit more performance from an amplifier and that small little box did not fail to impress.  I am going as far to say if I had to choose between the current setup and my previous top of the line... I am converted to the new technology and not sorry at all to have jumped shipped to digital amplification.  The switching technology is running at 600 kHz which is

I did swop between analog and digital and the NuPrime internal DAC is really good and better than the Squeezebox DAC.  Does not say much at the moment but future listening and comparisons will be done. The Coax is also clearly better than Optical Toslink.  I have not tried the USB and DSD formats yet as I like to get used to the first part before delving into higher bitrate. The digital signal between 44.1kHz and 48kHz is selected automatically as the source changes and briefly shown on the LED display.

What is next?  I have a subwoofer which will be connected to fill in the bottom end (I do not think any bottom end is missing but we will see) but I know lower end fills the other frequencies.  So it will just improve.  The nice thing is that there is a subwoofer out.  6V instead of 2V but change the gain on the volume of the subwoofer.  High res source files and comparisons to other DACs.

The only negative comment I can give if I can nitpick is a slight amp switch on noise through the speakers when you power on initially.  That is it!

For
Price. Even though not cheap, separates, such as a DAC, have cost me more
Slam and control and the bottom end
Very musical and presents the mids and tops in concert
Zero noise floor
Against
Nothing
Well maybe one... I want the IDA-16 (without getting rid of the IDA-8) and the wife will not be happy

I know this is a thread for the 8, but I just received the IDA-16 and absolutely love it.  I have one minor concern.  The owner's manual isn't much help regarding the analog outputs.  I figured they would be either fixed or variable to send to an external amp, but I'm not getting anything. 

When I listen to loudspeakers, I have an Audiophilleo 2 going into the IDA-16.  When I want to listen to headphones, I have to remove the AP2 from the 16, and hook it up to my Metrum Octave DAC which goes to my headphone amp.  I thought maybe the analog outputs of the 16 were fixed.  This way I can use the 16's DAC for everything and be done with it.  When using the analog outs going to my headphone amp, I got no sound from the headphones. 

I know about the home theater bypass feature (holding volumes up and down for three seconds).  So that's not it.

Post by: John Casler on 9 Aug 2015, 07:52 pm
What does that mean?

It means that the output of the analog outs is controlled by the Volume Control of the IDA-16, unless you set it for HT, in which case it is fixed at full volume, no attenuation.

Inputs however have memory, and will retain the "last" volume setting on that specific input.

I don't know about the power consumption, but there is no "automatic standby" on the IDA-8.

Standby would be when you turn it on or off via the remote, and not from the power switch on the rear, which turns off all power to the unit.

If its anything like other units I have had in my system?  Next to nothing.  At one point it had me wondering if my Furman Elite-15 DM i (which displays the AC current draw) was malfunctioning. I contacted Furman, and after they showed how to test it and was shown to be fine, said that its not normal compared to what they were used to seeing.  Even when not at idle!  :wink:  I think I may have even posted about it in this forum a while back.  Its that low.

Whether it works or not depends on the USB driver.  MacOS for example always support hi-res USB audio.
We have found that some NAS (running Linux) works for our DACs but we do not have the resource or expertise to support Linux.  Try at your own risk :)

"I was interested on the question related to idle power draw. is it rather 10W or 1 W?"

I must admit to having 'idle' curiosity over this question myself. Once I get settled in my new home in Taiwan with my new IDA-8, I'll try to either buy or borrow a meter that will show me how much power is drawn while it is in 'idle'. It seems to me this is an easily discoverable and/or easily tested problem, no?

It'll be about three weeks before I have time to seek out such a meter. I will post my findings here if someone else hasn't already posted it.

To "my ears" the dac in the IDA-8 sounds most similar to the Peachtree DAC-ITx in my office system.  This is not surprising as they use the "same" chip from different ESS families.  It is not to me up to the separate DAC-10 or W4S DAC-2.  To me the DAC was the least important part for the implementation it was bought for.  It needed to be simple to use and "non-tech" spouse friendly.  It does just happen to sound good too. Don't get me wrong the DAC is perfectly acceptable in a product of this type and price range, just don't expect it to be a "world beater."

Thank you JackD,

I haven't heard any of the dacs you mention but I have read several comparisons of the W4S DAC-2 with others that I have heard. You have given me a much better feel than I had.

I'm guessing the dac isn't warm sounding in any way but is clean and does what it's supposed to do.

Much appreciated,

In an integrated setting it is kind of hard to separate out which part accounts for the total sound.  I haven't tried a separate DAC into the IDA-8 myself but I know someone who has.  I suspect the DAC section of the IDA-8 has the same family house sound that all ESS DAC's do.  The total package to me is on the slight warm side of neutral which makes it a perfect fit for the Golden Ear Triton 5's which are just to the detail side of neutral. 
I run the DAC-10 in my main system so I can account for it's sound which is pretty much neutral.

I went ahead and ordered an IDA-8 in black from AA (hopefully with the 1x sub-out).  It should arrive mid to late next week.  I'll be interested to compare its DAC with my Bifrost Uber.

I certainly agree that with everything built in it's hard to determine what any piece of the puzzle sounds like. What's great is you can use another dac of choice and if needed change the sound to your liking.

I wouldn't expect any less from a hifi sales guy :D

Ha, that was my point. Let us know how the IDA-8 sounds with a different dac, I will be very interested in your findings. I've been keen on nos dacs for several years but dacs are changing at a rapid rate and I'm open to new products and what they can do for the music.

Some will want to use the only analog input as an HT Bypass or phono input, and if the internal DAC doesn't satisfy I would be more inclined to move on to a different integrated with DAC that does.

The silver units are in-stock and they are waiting for the black units to arrive from Nuprime, so I have high confidence that the black units (when they arrive) will be set to 1x based on John Casler's post in the pre-out gain thread.

I'll use the analog input for my phono pre, but I'll also a/b my current DAC with the integrated DAC during the 30-day audition period.  My plan has been to purchase a SET tube integrated (e.g. Decware Super Zen) and ping-pong between the IDA-8 and SET.  The only thing that made me question that strategy is trying to get "the best of both worlds" with the Rogue Audio Sphinx integrated (tube pre, Class-D amp) which has a high quality phono pre, but no integrated DAC.

Yes, I understand the intended purpose of the circuit but for $1000.00 you can add a dac you really love and have a great system. I personally in my application would use the analog inputs for HT purposes but I can see someone who doesn't do vinyl and doesn't have a HT set up wanting to use a very reasonably priced preamp with a dac to their liking. I know their are other units available but this one is getting some good reviews, I think it could be a good option for many.

All the current IDA-8 still has 3X gain (which isn't a lot) on the sub output.  I think people should go with the original design and unless you really need 1X, we can make the adjustment.  I am going back and forth on whether to go with 1,2 or 3X  :scratch:
May be we fix at 2X and then nobody needs to complain.

Just fix it to the industry standard and be done with it.  Then no one will have anything else to say about it.  Nobody with multiple subs already integrated into a system and calibrated wants to go through that process again just to swap out integrated amps.  In my case it didn't make any difference because I was changing out all the gear in that system from HT to 2-channel so the subs had to be redone anyway, but to others it very well could be a deciding factor and in the case of one pre-order owner it was.  Even in my case it does limit the volume control on the sub to the first quarter of the dial.

My sub's gain knob is already well under 50%, so I'm not crazy about the idea of reducing the available adjustment range or increasing the sensitivity.  If the 3x sub-out is specifically meant to cater to folks running multiple subs, that's great, but has that become the majority of the market for two-channel integrated amps?

Might I suggest something different?  Take one, or more, agreeable stocking dealers and supply them with both 1x and 3x outputs and see which one sells out first.  Or you could offer both options from the factory and tally both direct sales and dealer orders.  How much would it add in excess cost to maintain a small inventory of both options for a short evaluation period?

Hello, I am a new member of AC but have followed this thread closely.  I am about to pull the trigger on the IDA 8 but I have a few questions:

The onboard dac, does it provide for selecting the sampling rate or is it automatic?  Or does it not upsample at all?  My last dac allowed you to upsample the different inputs separately.
I have been reading about the sub output level-3x versus 1x.  What is the disadvantage of the 3x level?  I currently do not use a sub but if I do in the future, I'd like to know that I am using the "better" level.

Thanks in advance for your responses to these questions.   :)

The sub output will depend on the sensitivity of your subs input, and whether or not you used single of multiple subs.  If it is highly sensitive then the 1x would be preferable, which is now the default.

That's incorrect.  IDA-8 internal DAC does perform automatic up sampling to an undisclosed rate which we determined to sound "the best".

OK, so it does automatic up sampling.  That is fine, I just wanted clarification on that.  I am guessing that the unit does not tell you the rate while playing, so there is no way of knowing the up sampling rate?

Uhhh ..... I'm having a bit of difficulty understanding why non-proprietary information cannot be disclosed.  Although you may have determined which upsampling rate sounds best given a wide variety of source material, I have done a lot of comparative listening with my library and several quality DACs, and I have determined that even integer upsampling seems to sound the best to me.  Since the majority of my library is 44.1KHz (and likely to remain that way for many years), that would be 176.4KHz or 352.8KHz instead of 192KHz or 384KHz.

RWJR you can see the sampling rate at any time by using the mute button. As the unit comes back up to the previously set volume the rate is displayed on the screen. There may be other ways of finding it but that's what I've noticed.

We don't down sample it obviously but we never said that it will be up sample to 384.  We find that if the input sample rate is 44.1K, up sampling it to different higher sample rates have some slight differences and a particular sample rate sounded the best. We have to fix the up sample rate anyway, so we must well pick one that we think sounded the best.

Hello, Jason.

I'm going to give your (my) IDA-8 a run for the money. My new speakers will arrive  in Taoyuan at about the same time as my amplifier. The speakers are Fritz Speakers' LS/5-R two-way monitors which are  8 Ohm and 83.5 dB sensitivity. Don't worry, I won't expect concert hall SPL. I do expect really great sound quality from the combination though.

I'll report my findings once everything has broken in nicely.

Hi Ken,
Don't know if this will help you or not.  I have had the Marantz PM8004 for several years and my new IDA-8 has a more dynamic sound with better sound staging and depth.  Of course, the dac is still breaking in but the amp is quiet and it reveals poor recordings- it is not as forgiving as the Marantz.  Now the PM7005 might be different as it is a newer model, so your experience might differ if you audition both.  To me, the Nuprime is clearly better, so, I'll be putting the Marantz up for sale soon.

Hello,

Going to be picking one of these up later this month, but going through the documentation and the questions asked to date, I am not sure I saw the answer to this.  Could the line outputs be fixed or are they always variable?  I am going to assume that since they are meant for an external sub or a power amp that there isn't any way to facilitate them being a fixed output, but I thought I would ask anyway.

Thanks!

The most common uses for variable outputs are a subwoofer(s) or an external power amplifier. 

Fixed outputs might be desirable to feed a device that has its own volume control, such as a dedicated headphone amplifier or a zone amplifier.

This is exactly how I hoped I might be able to use it.  The fact that it doesn't have this ability is in no way a deal breaker - I am still buying one, but it would have been nice to be able to feed fixed analog outputs to a headphone amp for late night listening.  Almost using the IDA-8 like a pure DAC.

Thanks John.  I am looking forward to purchasing this later this month and trying it in my system.  If I like what I hear, I will be having a massive selloff of gear.  I am looking to simplify. I have 5 DAC's, 3 preamps, 3 power amps, 2 integrated amps, and 7 sets of speakers (plus all cabling), all acquired while looking for the all important (and elusive) system synergy.  A one box solution with a small footprint that works and sounds good and is as future-proof as anything out there really appeals to me.

If this ticks all the boxes for me, I will be looking squarely at the IDA-16 or the DAC-10H/ST-10 combo as the basis of my main rig.....or the Ref 20's if I win a lottery.   :lol:

Thank you very much for your input, Micheal - that is reassuring to hear.  I have many speaker to choose from - right now I am anxious to hear it with my Newform Research Line Source Monitors or my Tannoy Ardens with the 15" coaxial HPD-385 drivers.  I was hoping to have the ability to use the RCA outputs to drive a headphone amp.  Variable RCA outputs are affected by the volume control on the amp, while fixed outputs are not - they put out the same signal regardless of the position of the volume control  Having fixed outputs would allow me to turn the speaker volume to zero while still outputting a full 2.0V signal to my headphone amp for late night listening.

Again, not that big of a deal, and certainly not a deal breaker.  I have 2 DAC/amp combinations, so I could run a second USB cable from my computer to the headphone amp/DAC and use my phone to select which device will receive the signal from my computer.   :thumb:

Kevb,

We're thinking along the same lines.  :thumb:

I've had the IDA-8 for just two weeks, yet I'm already thinking/wondering about how an IDA-16 or DAC-10H might fit into my developing system. The IDA-8 was purchased as a 'second  home' system that was easy on my wallet and is very mobile yet offers good sound. Well, I got a home run with this plus my LS/5-R monitors. I had worried about the low sensitivity, but it just is not a problem with this amp and my smallish room.

I've got a big amp, a tube preamp and an older DAC sitting in boxes at home, and I can't help but wonder if the IDA-16 would make a great replacement or if adding the DAC-10H (to replace my aging DAC and the tube preamp) would be enough. In a perfect world, I'd con....uh...er...persuade John to send me both units so that I might be able to make proper comparisons. Any comparisons are months off as I am on the left side of the Pacific until March anyway.

I suspect you'll like the IDA-8, but that it will make you wonder what its big brothers/sisters are capable of.

Enjoy your journey!

Thank you Michael, I will be enjoying this new path.  :green: What I am really excited about is that I have only recently converted into computer/bluetooth audio, and I seem to have lucked into a great combination by chance as I am using my (essentially silent) HTPC build to run Daphile software from a bootable USB stick, and the sonics that I am getting running into my USB DAC's has been excellent - at the very least the equal of the sonics of the CD Players I have used as transports, with the added benefit of being able to play (and store) any format - not just 16/44.1 CD's.  And my HTPC cost just over $350 to build.   All the CD players in my house cost significantly more.  Time to move them out quickly!   :duh:  :lol:

If the IDA-8 works as well as the other USB DAC's in the house, I am going to be in for a treat.  Imagine a half-width amp (the IDA-8) sitting beside a half-width low profile PC, and the only thing else required is speakers and (optionally) a TV.  Minimalist, yet capable of doing pretty much anything but surround sound.  Which is perfect in my bedroom and family room setups.   :thumb:

Hello,

For those of you who have the IDA 8, do you keep it on all the time or is it better to shut it down so it cools off?

Thanks,
Rob

Hello, Rob.

I definitely shut it down, but not for fear of any damage. It's pretty hot here in Northern Taiwan - daytime temps have been averaging 26 to 32 Celsius with humidity so high one can almost drink it. The last thing my living room needs right now is a 24-hour space heater!  :nono:

I was so concerned about the heat (toward the rear right) that I emailed both Jason and John about it. Both assured me that this was perfectly normal, and that this is the best way to dissipate the heat generated by the unit. I simply ignore it now, though I am looking forward to harnessing that heat this winter. Homes in Taiwan do not have central heating even though temps sometimes drop down to the low to mid teens Celsius in Winter. (no central heating + rebar reinforced concrete walls + ZERO insulation = chilly home) Oh, yeah.  :|

Hi Michael,

Thanks for answering my question.  It helps as I was a little concerned about the heat as well.  My old amp I'd leave on all the time and it never got hot.  I am in Central Texas so I also have the high heat and humidity although my music room does have AC.  My room is warmer than the other rooms because it is next to the garage and faces West-so a lot of sun hits it most of the day. 

How do you like your amp so far?  The more I listen, the better it gets.  I am happy with it-it just plays all of my sources with clarity and with a lively presentation.  I wonder if the IDA 16 or the separates would be a step up?  Maybe if I develop a second system elsewhere in the house, I can explore that option, but for now, I'm content with IDA 8 as my music room is not large (10x13x10), so it is the perfect size and wattage.

I hope you are enjoying Taiwan,  I have heard that the Northern part of the island is beautiful.

Best regards,
Rob

I have a question about the IDA-8:

I have had this unit for several months now and really enjoying it.  It replaced a NuForce DDA-100 and to my ears is better in every respect (and the DDA-100 was very good to begin with).

My question is as follows:

Does the analog input into the IDA-8 remain in the analog domain right through to the speaker outputs ?  Any internal A/D conversions going on ??

The reason I ask is that I am considering getting a SACD player to play my modest but growing collection of Stereo Hybrid SACDs and just want to be sure that the IDA-8 keeps that pristine analog signal intact through to the output and does not do any internal conversions.

Thanks in advance for any definitive answers that can be provided about my question.

If you could rip the SACD's to a computer, you could use the computer as the source via USB to keep everything in the digital domain until it reaches the IDA-8. That is how I will be using mine. I have downloaded a few DSD samples from 2L, and I can't wait to hear how they sound when I get the IDA-8.  I would wager to guess that going digital direct to the internal DAC in the IDA-8 would trump a modest SACD player through the analog inputs. 


Just a thought.

Post by: JackD on 7 Oct 2015, 01:37 am
SACDs were recorded using DSD to start with so using the Analog outputs on the player already involves a conversion. I don't know why the Analog inputs would involve digital processing unless Jason says they do.  I would think that your best sound may come from using the digital output from the player to the IDA-8 and letting it upsample, but try it both ways and see what you think. In the system I am using mine in I have an Oppo hooked up using the 8's internal DAC and a CD Player using NOS Burr Brown chips into the Analog inputs.  They certainly don't sound the same leading me to believe that the Analog inputs are bypassing the internal DAC.  If they were both being processed they should sound basically the same.

JackD,

Have you compared the Oppo's dac with the dac in the ida-8? If so, how would you describe the differences.

I am still very interested in what people have owned that they can compare to the ida-8 as I'm still not getting a good picture of what it sounds like compared to anything else at this point. Being used to having tubes in the chain I'm very curious as to how the ida-8 compares since I recall Jason saying it was on the warmish side in presentation.

Any input from users would be greatly appreciated.

It is warmer than the Oppo, but not as warm as the Burr Brown in the Classe' CD from 2000.  I don't know if you have ever heard one, but the Classe's sound is very similar to the tube output Norh CD-1.  The closest thing I own or have heard that compares to the 8's DAC is the Peachtree DAC-it. The problem with what you are asking with an Integrated is that you can't separate which part of the chain is the main contributor to the sound profile.  I own the "8" and the DAC-10 but haven't heard the "16" or the ST-10.  I have a friend that has owned the 8 and the 16 and he feels the front of the 16 is better but the amp in the 8 is better.  My dealer hears the same between the integrateds and thinks the combo of the two 10's beats them both handily which is in line with what the reviewer from TAS heard.  I intended to have an ST-10 in house by now, but a new speaker purchase has put that on hold.

If that is in fact the case, then the $1600 extra for the 16 would seem to be a bit of a problem. I have the IDA-16 and am very pleased with the sound, in what way is the amp of the 8 better sounding ?

I'm going to look for it to be certain, but I recall Jason's making a statement (in this thread or another) in which he compared the IDA-8, IDA-16, and ????. [I believe the unknown other was the ST-10.] If I do find it, I'll repost it below.

Edit: Okay, I went back through Jason's posts and found this post:

The following brief guide might help you decide between ST-10, IDA-8 and IDA-16
Sound characteristic - ST-10 has the perfect balanced for people who is looking for some texture, warmth and yet detail and resolution in an amp. It also has gripping control and bass. ST-10 is the best you can get before moving upward to Reference 20.
IDA-16 is very well balanced and detailed. For entry level high-end audio, IDA-16 is a good place to start and you won't easily run out of power.  It has everything you need, including a DAC with enough resolution and inputs that will not need any upgrade for  the foreseeable future.
IDA-8 sound characteristic is between ST-10 and IDA-16. If you have high efficiency speaker, or bookshelf speaker in a small listening room, this is the best integrated amp on the market. I don't think anything below $2K would be able to compete with IDA-8. At $995 that also include bluetooth aptX and DAC, it is as future proof as you can get.
If you are looking for a reason to upgrade your old mini component or outdated entry level audiophile system, IDA-8 gives you everything you need in one box.

Kevb,

We're thinking along the same lines.  :thumb:

I've had the IDA-8 for just two weeks, yet I'm already thinking/wondering about how an IDA-16 or DAC-10H might fit into my developing system. The IDA-8 was purchased as a 'second  home' system that was easy on my wallet and is very mobile yet offers good sound. Well, I got a home run with this plus my LS/5-R monitors. I had worried about the low sensitivity, but it just is not a problem with this amp and my smallish room.

I've got a big amp, a tube preamp and an older DAC sitting in boxes at home, and I can't help but wonder if the IDA-16 would make a great replacement or if adding the DAC-10H (to replace my aging DAC and the tube preamp) would be enough. In a perfect world, I'd con....uh...er...persuade John to send me both units so that I might be able to make proper comparisons. Any comparisons are months off as I am on the left side of the Pacific until March anyway.

I suspect you'll like the IDA-8, but that it will make you wonder what its big brothers/sisters are capable of.

Enjoy your journey!

Michael

I thought I'd repost my own post from a couple days ago given the information that I posted above. Now I see the IDA-16 is not in my future. I do want to get the DAC-10H into my main system (once I'm back in my home in Oregon). Then, my next step would be to decide if that is enough, or if I want to replace my big amp with the ST-10 or the Ref 20 amp. Fortunately, that decision is many months in the future.
Title: Re: IDA-8 ($995) features and spec
Post by: JackD on 7 Oct 2015, 12:51 pm
By better they meant fuller. They both thought the amp section in the 16 was on the "lean" side in the lower octaves. Again I haven't heard the 16 just their opinion.  As to the 10 combo you have the advantage of two separate power supplies which is an advantage to start with. Not to mention future flexibility and they are pretty much the same size.

JackD, thank you for this. My friend is bringing over his Oppo 105 pretty soon so this will finally give some idea of what this integrated sounds like. I appreciate that being an all in one solution you can't separate what is making what contribution but what comes out at the end is what counts knowing you can't change things up.

That will be a tough decision for me as well.  With the recent tanking of the CDN dollar, I will have to hear it in my own system before I commit big bux.  Especially since I am also looking at going another route with another comparably priced DAC/pre from another company (NFB-27H from Audio GD) and using that with one of my current power amps.  I do love the minimalist styling of the NuPrime gear though - small and unobtrusive, and the biggest thing for me was simplifying so I could get rid of a whole bunch of cables too.

Going to be a tough decision....hmmm.....   :scratch:

"Better" is subjective.  I would say that "Better" should be reserved for the spec.  IDA-16 has more power than IDA-8, etc.
Sound wise:
IDA-8 customers typically have entry level high-end speakers from $1K to $3K. So we designed the amp to be slightly warmer with more texture. Sure, even a $5K or $10K speakers can sound really good if you like the sonic characteristic of IDA-8. But if you play very loud in a big room, IDA-8 will not have the power or dynamic for hard to driver speakers.
We designed IDA-16 to be clean, neutral with lots of details. This suits people with high-end speakers where they want to "tune" the overall sound.
ST-10 and DAC-10H combines the best of IDA-8 and IDA-16 and take it to the next level.
Why don't we just make IDA-16 as ST-10+DAC-10H ? If we can do it within the cost, we will.  We don't play the pricing game or sell some bull shit thing.  It will work if we sell a $3500 IDA-20 that combines ST-10 and DAC-10H.  But we are concern that the market will be too small for such a high-end integrated.  At the higher price range, people want to go with components.

I amended by statement from "better" to "fuller" and again that was what I was told.  Whether or not an IDA-20 would work would depend on how the current projections for the Devialet and others look now that the "new" has worn off.  Maybe just "re-voice" the amp module in the 16.

Jason,

I've got a couple questions and an observation or two.

You stated, "IDA-8 customers typically have entry level high-end speakers from $1K to $3K. So we designed the amp to be slightly warmer with more texture. Sure, even a $5K or $10K speakers can sound really good if you like the sonic characteristic of IDA-8.

ST-10 and DAC-10H combines the best of IDA-8 and IDA-16 and take it to the next level.
" and "Yes, we designed IDA-8 to have more "texture"/fuller sound characteristic."

I'm not sure how to translate 'more texture/fuller sound' into what I'm hearing when I listen to music with my IDA-8 and speakers. Can you elucidate a bit?

I'm a bit atypical in that I'm using the IDA-8 to drive pretty high-end bookshelf speakers that aren't exactly high efficiency. They use the Scan Speak paper Illuminator 5" midwoofer and SS Ring Radiator tweeter (Frequency Response: 43Hz-30Khz +/- 3 db; Impedance: 8 Ohms nominal; Sensitivity: 83.5 db (1 Watt, 2.83 V @ 1 Meter). I had been concerned about the 83.5 dB sensitivity, but it just isn't an issue in my small space. The IDA-8/LS/5-R speakers are a great combination IMHO.

Your comments above have made me quite curious about how my experience would change if I had an IDA-16 (or ST-10/DAC-10H) instead. The sound I would hear would be different not only because of the more watts/ch, but also because the amps are tuned differently. Do you know if the store in Taipei (that sent me the IDA-8) is set up with a listening room? If so, do they have the different amps in that room available for someone like me to walk in and compare them?

Regards,

Michael

IDA-16 doesn't need to be "re-voiced". If you like IDA-8, then you might find IDA-16 "too clean".
Technically, IDA-8 has more even harmonics.

Hi Rusty and you guys.
I've been looking into your products, and need an advice.

The situation:
small room - might change later
Playing hi res files JRMedia
preamp/HP amp/ DAC - Audiobyte Black Dragon - 2 balanced + 2 unbalanced outputs
phono stage + phono preamp
HP - Sennheiser HD700
Loudspeakers - DALI Mentor Menuet Special Edition (Limited number with upgraded components)

So I am left with the question of amplification:
I have been considering IDA-16, IDA-8 and ST-100.
To me, the ST-100 looks like what I need so I can connect both the record player and what comes from the Black Dragon into the amp without the need for a switch.
I am also hoping extra Power does good for the tiny loudspeakers.
I am trying to get i right in a tiny room, but also building a chain of components that can be moved into a larger room - and supplied with larger speakers when the day comes.

Or would you think it wiser to og With the IDA-8/16? (It certainly wouldn't be practical...)

Would be good to hear what you think.
Title: Re: IDA-8 ($995) features and spec
Post by: JackD on 9 Nov 2015, 06:52 pm

I agree with JackD, ST-10 (Product of The Year award, announcing Nov 27) is the best for you (you mentioned the ST-100 but I think you are referring to ST-10, ST-100 was the old NuForce amp and not in the same class as ST-10).
If you have budget concern, then go with the next level down, STA-9 that will be shipping Dec 7.

Hi.
Yes I meant the ST-10, the Nu-Prime. I'll have to talk to my dealer again :)
Thanks for the advice, really looking curious to the combination of Black Dragon and ST-10, which both are said to be superneutral, but with some ease from the ST-10. I'm an honesty kind of guy, been playing in too many studios to want tube warmth and all that :)

Looking forward to more information on these new releases.  I love my IDA-8....the IDA-8 with a $400 purpose built PC makes a stunning match with my $5000 Equation 15 speakers.  It's crazy how amazing it sounds....the Equations are an easy load at 6 ohms and 90db.  They need quality much more than quantity, and the IDA-8 delivers in spades.  In fact, it is the best match I have by far for the Equation speakers.  I would trade almost everything I own to get the DAC-10H with the ST-10 or the Ref 20's.

I can't possibly answer your question because I have just one Nuprime product. The easiest way to fix this problem is to immediately send me an ST-10, DAC-10H,and what the hell an IDA-16. You (or John) already have my address.

If depends on the emphasis of amp or DAC.  But in this case, it is not a fair combo.
ST-10 is clearly on a different class, right below Ref 20, than all other amps (ignoring power, because even though a good power supply affects the sound, but power alone is not a quality characteristic, it is a requirement).
The difference between two NuPrime DACs are not that far apart.  Normally a $749 DAC-9 would not be considered reference class, but things have changed from the past few years.  DAC chips are getting closer in performance. But more importantly, we also developed new circuit capability (such as FPGA based switch resistor network for volume control that bring traditional $3K to $5K preamp design to a $749 product) and design knowhow.  A new US dealer just commented that DAC-10 has the only good sounding ESS implementation that he has ever heard. That might be a bit bias, but my point is that it takes much more to make a DAC sounded good, preamp being the most critical part.

Hahahaha.....so you are still loving your IDA-8?  How are they with the Fritz speakers?

Ya know, I actually do really enjoy my IDA-8. And yes, the Fritz speakers I own have pretty low sensitivity - though that is somewhat modified because of the series crossover. The tweeter is easier to power. It's a really good amplifier, but it is only 100w per channel. I learned a couple years ago that a 150w or 200w amp powers speakers differently even at lower volumes. I'm not dissing the IDA-8, but I can't help but wonder how the IDA-16 differs (not talking about specs or descriptions; I'm talking about how it sounds).

Perhaps what I imagine doing someday is to hand my IDA-8 over to a rep in Taipei to modify the amp so I can add the new (so many new products I forgot the correct name) 100w amp for a bridged setup to give me 200w per channel. I'm pretty sure this isn't possible, but I think it would be pretty cool.

I'll put it another way. I like it enough that I am not willing to trade up to the next level. I'll only get $XXX resale plus I must spend another $XXX to get 'N' sound improvement. I'd rather hang on to the IDA and save my pennies until I have enough to try out the DAC-10H in my system in Oregon. I'm due for a better DAC in that system. If the DAC-10H is as good as the hype/reviews claim, then I'll be interested in comparing my amp to Jason's best. I'd rather have one killer system and one really good system rather than trying to stretch my $$ too thinly between two systems. The IDA-8 is really good and my speakers are excellent.

Ya know, I actually do really enjoy my IDA-8. And yes, the Fritz speakers I own have pretty low sensitivity - though that is somewhat modified because of the series crossover.

Makes sense to me.  I am now intrigued by the DAC-9 as Jason has said that it has near reference class sound too.  And the real bonus for me is it appears to have the same bluetooth input as the IDA-8.  That has become invaluable as my wife and kids can just stream from their devices whenever they want to. Never in a million years did I think they would care to, but now they can throw on music whenever they want, and they have been - often.  It is the main reason (besides budget) that I am willing to sacrifice that "Nth" degree to get the added convenience. That way I have more budget to put towards the ST-10 if I can swing it.  Let's put it this way, if I went for the DAC-10 or DAC-10H, I would most likely be limited to sticking with my Crown XLS2500's (2 of them).  If I go for the DAC-9, I can swing the DAC-9/STA-9 for around the same price as the DAC-10.  That or even step up to the ST-10 if I can swing it.

So many choices, not enough money!!    :icon_lol:

Michael,

You want the STA-9's, but the GOOD NEWS is they DO NOT bridge to 200wpc any longer.

THEY BRIDGE TO 290wpc!!! (120wpc in stereo)  for $649 each.

And since you have the 2v output on your IDA-8, you can use them with the IDA-8 as a DAC/Preamp right now. :green:

That is better than what I had imagined doing. Is the '2v output' on my IDA-8 different from the output to subwoofer? I ask because my subwoofer output is 1x.

1x = 2v output, and is the standard output of CD players and such.
2x = 4v
3x = 6v

The output voltage would just mean that the Volume Control would be at a different point (db) depending on which output you have.

So if a 2v Volume setting was 1:00, a 4v setting would be lower, like maybe 9:00 or 10:00.

It also depends on the sensitivity of your amps.

This is slightly less important with the stepped ladder resistor network Volume Control since it doesn't work by large increases in resisting the signal.

I now had the chance to listen to the IDA-8... and I liked it very much! Even though I won´t keep it, there´s one crucial feature missing for me: A simple balance control. In my setup one of the speakers is positioned close to a room corner while the other speaker is not. There´s no way to change that at the moment, with my current amp I can correct the shifted middle by adjusting volumes for each channel separately.

I am wondering... after reading a bit about the technical side of the IDA-8 I understand that volume control is done by using lots of resistors and switching them accordingly. Shouldn´t it be quite easy to implement a balance regulation into that kind of volume control?

Thanks for your help,
Oliver

Adding balance control will degrade performance. You can try to change the placement of the speaker just a little.

Are you using a computer source? If so, you could adjust balance in the digital realm.

You're asking them to implement a rather non-trivial change into both hardware and software.

Thanks for your suggestion... if I could do that I hadn´t wondered why the IDA-8 doesn´t provide a balance control. Actually I had to move the wall of the house, then... something like four meters! ;) Anyways, thanks for your answer.

One question though: Why would sonic perfomance be compromised by adding a balance control, especially given your choice of volume control (one single resistor for each channel active)? I unterstand that the choice of the active resistor(s) is done digitally, so a very simple program could do the job of not using the exact same values for the resistors for each channel? But maybe I am getting the whole idea of how the volume control actually works completely wrong.

Not the best remedy, but slightly adjusting the closer (louder) speaker so that it is firing ever so slightly "off axis" can offer a modicum of balance of the output to your ears.

Hi.

What speakers do you guys and gals use with the IDA-8? I'm looking to upgrade from the Quad 12L2. I'm looking for a pair of standmounts with more clarity to a room 3m x 4m with half of the room open on one side leading to the dining room. Budget is $2000 preferably available to buy in Asia. Any suggestions? Good or bad experiences?

As always, late to the party.  I was able to secure an IDA-8 a few weeks ago after a move 3000 miles keeping me away from my main system.  Now I can't wait to get to my main system to sell it all off :).

I have owned several integrated and monitor based systems.  Simplicity first.  I've owned many monitors and the Penaudio monitors have never failed to ever disappoint.  Just a consideration....

Hi Greg,

Due to a cross country move...  The last time I saw my stereo system was 3-months ago which consisted of a Hegel H160 integrated in one room and a Hegel H80 and Hegel HD12 DAC in another room.  Clearly, a proper A/B will be performed in the months to come...  but the IDA-8 is no slouch.  Further, I was literally able pack the IDA-8 back into its box- the size of standard laptop packaging and move again.  So much combined into the one box design is impressive.   I am in no position to gripe... But a headphone jack would have been great too :).

This easy portability was one of the main reasons I decided to try the IDA-8. It's got a nice sound and the DAC is no slouch. If I had to gripe about something, I'd wish it put out 150w/ch and had a second optical in. This is great for a starter system or a vacation system (such as mine).

A subwoofer question. Forgive me if this is a dumb question; I am a neophyte. 

I am looking for a small integrated amplifier to hook up to a pair of bookshelf speakers and a powered subwoofer.  The IDA-8 looks great, but I am uncertain how it will work with a 2.1 system. 

If I were to connect a subwoofer to the analog line-out of the IDA-8, the amplifier how much overlap would there be in the reproduced frequencies by the speakers and the subwoofer? 

What I think would happen:
1.  The speakers get a full range signal and will reproduce the frequencies that they can.

2.  The subwoofer amplifier will get a full range signal, but the cross-over in the subwoofer amp will apply a cut-off frequency (i.e. 100hz or 80hz, etc). 

Do I have the correct?

Is there a downside to this approach, versus an integrated amplifier that has the ability to limit the low frequencies sent to the bookshelves? 
It seems to me that if the bookshelves could be spared from trying to reproduce the low notes handled by the subwoofer there might be lower woofer excursion and so better controlled mid-range.  Am I off base?

Thank you,
Mike

Hi Jeff,

I tend to agree with Michael.  You might find the Bass Response exceptional over other possible choices since the damping is quite high in this design, and this gives cleaner and deeper Bass than lower damping amps.

Also due to the high efficiency you will find the Dynamics and Headroom off the charts.

I have a lot of customers with many different speakers, but haven't had any with the Omegas yet.  on paper, they look good together.

Sounds like a winner. I have read a lot of good reviews on it and I for sure need the headroom and dynamics due to the kind of music I listen to. Alot of Metallica and Primus stuff like that. Alternative and metal. I listen to everything but want an amp that will also shine when listening to very demanding music. I also have read that this amp is pretty silent. I know it's not a huge deal but I don't want to hear hiss during quiet passages in music. I read a review that stated he turned the volume up and paused his source and heard no feedback. Is this true? I am so torn between this amp and the amp that I keep reading has perfect synergy with the Omega's, the Decware SE-84 UFO. It's a VERY hard choice. Both are the exact same price. What do you guys think between those two options?

Yes, the noise of the system is quite low.

And I can't tell you what the SE84UFO will sound like in comparison, but you can see that the power output difference is significant.

Additionally the "feature set" is quite different.

With the IDA-8 you get digital and analog inputs, a full DAC function, and remote control to change inputs and volume levels.  Just add sources and go.

Your points are all correct. Yes the speakers will get the full range while the powered sub will cut off with a low pass filter. I wouldn't really worry about it at this point. Yes you could start looking into more complex arrangements with proper external crossovers leading into eventual bi/tri amping situations, but the whole point of using an integrated is to keep your life simple right?

You could also try looking for speakers that may have a high pass filter built in to them naturally.

Yeah.  The IDA-8 is looking like the choice I am leaning towards.

How does the IDA-8 compare to the 16?
W/P 5.1
The IDA-16  has more control and in a seperate test we found that the IDA-8 drives speakers that require more power very well but it has limited volume.  One specific speaker tested was the Audio Physic Virgo 25.  The IDA-8 sounded really good but felt it needed just that extra bit of power when pushed hard.  The IDA-8 I found to be similar sounding at all levels.  It does not lose composure, just goes louder until max volume.  I presume there is a logical limiter which controls exactly to ensure optimum delivery.

The IDA-8 brings more 'bass' out compared to the IDA-16, but the IDA-16 has more refined sound at a close to a reference stack. 

I have also taken the leap and bought the DAC-9 with 2 x STA-9 (bridged) to get more power and control.

The only problem I have with NuPrime products is that I find I am running out of rooms in my house to put them :)

The IDA-8 is better value for money IMHO but the IDA-16 is the choice for me if you have 'play' money. HTH

Thanks for your comment. That's our design goal for IDA-8. It is a do-it-all and supposedly future proof (even though one can never predict) integrated. You can mix and match until you are confused with the rest of the DACs and amps combination.

Maybe the problem is the "4 Ohm" of Audio Physic Virgo 25 (89dB). Well, the minimum impedance is near or below 3 Ohms in [100 Hz - 1 or 2 kHz]

More traditional class D amplifiers have problems with low impedance.

There are lots of speakers, it is best to focus on those that we know its impedance, phase, frequency curves.... I think.

And class AB amplifiers with MOSFET too with 2 Ohms. Solution: pay for double die ($100) like stereo AVA. Or two mono.

“I finally set up my bedroom system with the IDA-8 and the KEF LS50s with the new subwoofer. With the Bluetooth dongle the sound is pretty impressive. … It is pretty amazing what that amp can do for that money-that amp is easily the equal of some 2k amps I have heard. … The LS50s really continue to amaze and really benefit from the sub in the system.”
– Jeff K, VT (a happy IDA-8 owner)

KEF LS50: 85 dB and 3.9 Ohms minimum at 200 Hz

-> http://www.stereophile.com/content/kef-ls50-anniversary-model-loudspeaker-measurements

More cheap and ease to move my KEF Q100: 86 dB and 4.7 Ohms minimum about 200 Hz. I think is ideally to Nuprime IDA-8 or STA-9 amplifiers. And I love the magic sound 5.25" Uni-Q KEF coaxial!

PD: KEF LS50 has rear bass-reflex in the rear. They say that they need minimum 3 ft (1 m) to rear walls side walls too! -> it need big room and more power.

KEF Q100, with front bass-reflex, does not have these limitations.

Thanks for your comment. That's our design goal for IDA-8. It is a do-it-all and supposedly future proof (even though one can never predict) integrated. You can mix and match until you are confused with the rest of the DACs and amps combination.

When you say "future proof " what  makes this amp future proof?  Can you elaborate?

I don't forsee DAC's performance going beyond DSD256 and 32-bit/384kHz any time soon. The majority of the content are still 16-bit/44.1K and even most of the hi-res music are 24-bit/96kHz with some at 192k or DSD128.

The amp design is really good and we don't forsee innovation that can dramatically change that. The fundamental design for Class D has not changed (cars are still 4 wheels and bicycles are still the same design since its invention). It is still possible that in a few years, we can price IDA-8 cheaper (I foresee NuPrime selling amp module and customers download the case design and 3D print on local shops) but no drastic change to the performance. It is difficult to overcome these physical limitation.  It took almost ten years from 2005 where we came up with audiophile quality class D amp to reach what we have today. Last year was the "Great Leap forward" year where we have explosion of designs and ideas (all these products were designed last year). And all of you have validated that these new amps that cost a fraction of the price of other high-end amps easily out perform them.

There is a digital port which is actually S/PDIF and +/- 5V supply at the back of the IDA-8. That is designed to connect and power external receiver such as NuPrime WR-100 or next generation NuPrime Omnia receiver (capable of 32-bit/384 or DSD256 streaming, expected June 2016).  We don't build WiFi audio into our amps or DACs because that will make it obsolete.

No a good idea. You should just use the coax for the digital SACD and CD from Denon.  The analog input is mainly for entry level turntable (with line out) or other device with no digital output.

I believe SACD copy protection will prevent digital output over S/PDIF and many players, if they do output DVD-A over S/PDIF, often downsample that to a lower resolution.

You are right.
Now it depends on how much he uses the Denon versus computer source. If the ultimate performance is required, then the analog input from IDA-8 is not ideal. He should go with DAC-9 and STA-9.
I just read the draft copy of The Absolute Sound review of IDA-8 and half of the time the reviewer was using turntable with IDA-8 and she was very impressed with the sound. I think a lot also depends on how good is the DAC implement in the Denon. my point is that if the D2A is not the best, then another step of A2D wouldn't have that much impact.

I'm guessing because the analog input is digitized, meaning you would be going through an unnecessary Analog to Digital and Digital to Analog conversion.  While perhaps not necessarily sounding bad, it's certainly not the purest route, particularly for your SACD and DVD-A sources.

I know the IDA-16 is 2.6X the price, but I don't see the parenthetical "(analog input will be digitized)" after its analog input spec, so I'm just curious if that amplifier provides a true unaltered analog path for the analog input or was it just omitted from the specifications copy?

As we discussed on the phone, getting an OPPO 103d, which converts SACD to PCM, might be a reasonable and potential solution.

IDA-8 is the only product at this point where the analog input is digitised. There is just no space and no extra cost to do that. But the A2D is very good. So unless your analog input came from very good source, you might not notice the A2D conversion (i.e. you can't tell the difference)

DAC-9, DAC-10, IDA-16 all have analog input all the way without A2D conversation.

Wow, thanks for the info. I now understand why the IDA-8 uses the 5V digital supply for the RCA input opamp NE5532 and not the +/- 12V from the dac i/v (LM4562) +buffer (NX5532) section. It is to completely separate the digital input and the analogue output to the amp section. Your info also solves the mystery of where the heck did the signal went after the opamp output, I spent a lot of time tracing it to no avail. (Sorry, its just the diy blood in me)
I am thinking of  adding another Nuprime but the ST10/Dac10 is just too deep and I don't have enough space. Is the STA9/Dac9 a good step up from the IDA8? I am a bit hesitant for the Dac 9 since it uses the AK4490. The AK4495 is a step up and I have got a dual AK4495 dac coming. If Nuprime uses the latest AK4497, I will be definitely getting that.

It uses the Sabre ES9010 (DNR 116dB, THD 106dB). The next dac up is ES9016 and the top is ES9018. I guess ES9010 is use due to IDA-8 price level, but it does sound pretty good.
Newer reference Sabre dac has been announced call ES9038pro. I looked forward to seeing that inside a Nuprime.

IDA-8 is definetely on my radar. After purchasing other brand amplifier for separate system I no more have any reservations regarding class D amps.
My only concern is power. Now my Gershman AvantGarde speakers are powered by Krell 400xi (200w/ch, 350 into 4 ohms). Wonder how much I would loose with just 100 watts (but speakers moving to a room half the size).
I have no concern re: low end DAC chip model, there so much more going into integrated amp it is a no-issue.

Power figures are very deceptive. A doubling/halving of power is only 3dB difference, assuming you were even maxed out to begin with. In a home environment, most people don't use more than the first couple watts unless you were pushing some really inefficient boxes.

This is true. Wattage power also is deceptive anyway, as there are issue with current, etc. And amount of current delivery of an amp is a rarely publshed number.
To sum things up -just wonder if anyone tried to drive Gershmans with IDA-8 ))

Hello, oldzorki.

I think I can partially answer your question. I have never driven Gershmans with my IDA-8 (or any other amp), but my speakers are 83.5 dB sensitivity - though due to the series crossovers they are easier to drive than 'regular' low sensitivity speakers.

I've had a couple other amps drive these speakers, so I have a pretty good idea of how it compares (at least to the other amps anyway). I'd say that the IDA-8 does a decent job of powering my speakers if I am not trying to listen critically. To be fair, most of my music listening is non-critical because of my room, my habits, and my dear wife. It is only when I want to really listen, really pay attention to the recording that I realize the 100 watts isn't giving me all the speakers are asking for. Mind you, I'm not listening at unreasonably high levels either.

If I could re-engineer my IDA-8, I'd replace the 100w amp with the ST-10's amp [Would that make it an IDA-10?], or with a nice EL34 tube amp. Either mod would probably make me a pretty happy camper.

I really like my IDA-8 and I really enjoy its features. I have my Squeezebox Touch feeding it wifi from my Mac Mini, Bluetooth from either my iPad or iPhone, and my TV feed via optical. It's amazing how much this amp offers especially considering its very reasonable price.

If my speakers were 87 dB to 90+ dB, I would be enthusiastically telling you to rush out to buy an IDA-8 (because it's that good), and I wouldn't be telling you about its shortcomings.

Enjoy your search.

Thank you Michael for a detailed response. Gershman have a dual reputation - some say they are easy to drive, some say that they sing only driven by 500 w/c behimoths. They are fairly sensitive (87-88) and do not deep below 6 ohms - but something in their crossover is not agreeable with certain amps, or so tells the legend.
What size of room you are listening your speakers in? I found room size and distance from the speaker as much important as anything else..

"What size of room you are listening your speakers in? I found room size and distance from the speaker as much important as anything else."

I just measured (it's been a while since I did this). The living room is 23' L x 12.5'W x 9'H. As you face the TV/speakers, the right-hand side of my 'box' is open to a dining room (add another 13'L x 8.5'W), so my listening space is actually quite wide. My speakers are set up on one of the long walls (more or less centered on the living room) on either side of our wall-mounted flat screen TV. They are on 22" four-post stands placed approximately 20" off the front wall, but I pull them out to 3' when I want better sound (and the WAF issue is out shopping).

The walls and ceiling are rebar reinforced cement. The floor is a floating wood floor (teak). There is a throw rug located between the TV and the sofa. There are practically no acoustic diffusors/absorbers on the walls. It is not an ideal room for well behaved sonics.

I have at times relocated the speakers to the left-hand short wall four feet from the new front wall. Ahh. The speakers/IDA-8 make musical heaven there. I'm sure there's a good reason why I don't keep them there (wanna meet her?).

Thank you Michael for a measurements! I am well aware of WAF factor and limilations it brings (been married for 30 years :) ), however this setup is for my office, hence it does not apply fully (however make no mistake - good looking equipment goes a long way for a spousal approval regardless of placement). And IDA-8 is unquestinably a good looking piece!
If we add depth of your coach and distance from the wall to the speaker, your listening position now is approximately 9 feet from your ears to the speakers. Is that correct?
In my office setup speakers will be appromimately 7 feet from me.. But room itself is much smaller, prehaps 120-130 sf, not more. So i Hope that ID-8, combine wth more efficnent speakers, will suffice.

I agree, you can never have enough power with an amp. You may get better sound with something with less power thou, just by the nature of the type of amp you are using. I believe more power is safer than too little power, you don't have to worry about the amp clipping and distorting which can cause way more damage that just pushing your speakers too hard.

This is very true. I would like to see how this amp goes into clipping, however I was not able to find measurements and charts anywhere.
But I want it regardless. I really like engineering approach of NuPrime, and design IMHO is awesome.

This will be intersting. Most digital amps measurements I have seen display fairly extreme behaviour at the point of clipping.
Mot manufactures do not like THD vs watts charts, as they do not represent behaviour under normal conditions and can be misleading.

Oldzorki,

Over the weekend, I was able to hook up my IDA-8 to some quite large floorstanders (probably 89/90 db efficiency), the VMPS RM40 and it gave them everything they needed.

Played very loudly, without a hint of stress.

My speakers are similar to these

Class D amp has been improving leaps and bounce over the years. I remember in the "old days" like 2005 to 2010 or so, everyone is talking about THD numbers. Same thing can be said for the sampling rate of DACs.
But now, several of the top tier class D amps (NuPrime especially) have moved beyond those numbers. THD < 0.05 is common over a wide range of power and freq so we stop talking about it. It is no longer interesting. You can't tell the difference beyond certain low THD numbers.
Similarly for DAC, we just created the mDSD under Encore brand for $99 with 32-bit/384kHz and DSD256 decoding. Sound quality is incredible.
By the way, for amp, you want to turn up the volume and typically the best performance (the lowest THD, best dynamic) is at mid volume level.

So what's the next battle ground for class D amps if low THD is now the norm?
1) switching frequency - all the NuPrime amps now switch at > 550kHz.  Why is this important?  It has to do with converting the analog music into pulses with varying height. With > 10X the sampling rate of CDs, you can't tell from a class D or class A amp anymore.
2) mix of class D power stage different preamp stage to create amps with different flavours. You can't tell STA-9 from a high-end tube amp. Our French distributor told us $649 STA-9 sounded better than his 5000 Euro class A amp.

Power supply and chassis now becomes one of the deciding factor for cost. Your smart phone has more computer power than a super computer of yesterday, so believe me, we can make our class D amp sounded like anything.
3) price.  Good design, very reasonable price.

By the way, the deciding factor in a DAC product is no longer the chip. Realistically, the difference between ESS9018 and ESS9010K2M is not noticeable if the rest of the design is very good.  Typically in a so called entry level DAC, vendors use lower price  DAC chip but what makes it sounded not so good is the preamp, jitter reduction circuit (or lack of), volume control, power supply circuit etc.
If you have a high end in-ear earphones, try the $99 Encore mDSD to decode DSD256 or 32-bit/384KHz music from your smart phone to hear what I am talking about.

Next month I will take about some innovative stuff we are doing for Omnia. One of the most important design feature is to decouple the music decoding and streaming from the CPU. This can't be done on a standard PC or smart phone. It needs propriety design on the "motherboard".

Post by: oldzorki on 8 Mar 2016, 10:36 pm
  • Bandwith audio at -3 dB (aka Frequency response) < 50, 60... 80 kHz. The next generation should reach at least to 100 kHz. Maximum about 350 kHz to avoid problems with RFI / EMI interference I think.
  • Well, usually I play vinyl rips 24/96 FLAC. Maybe switch 20X / 1 MHz would be other target.
I amassed quite a bit of 24/192 downloads from HDTracks, I also have plenty of SACD rips in DSF files.
May be 4 MHz switching supply one day? )))
I found nowadays D amps remarkable. I use W2S new amp in HT system (and it is not as advanced as nuprime, based on IcePower) - and this baby is smooth.
So my only concern was power, and I believe my questions have been answered. I am ordering IDA-8 in a month (I am in a process of moving).

Off-topic

Unless new recordings (classical an jazz), HDtracks and SACD sound worse than excelent vinyl rips I hear. With commercial music before the eighties the difference increases!

Many vinyl rips in 24/192 sounds a bit false and take up much space.

Many HDtracks are cheaters, they use the 16/44 digital master of CD upsampled to 24/96  :x

continue off-topic, sorry
Matty, my friends share with some od their rips. And it is hit or miss (to my ears) - some sound good, some are not.
And I agree, too many so-called hi-rez remasters sounds horrible. I just bought "Hello, I Must be Going" by Collins on HDTracks -and already regret it.... Terrible!
But some remasters sounds wonderful and way better (for me) then rips. And yes, it includes jazz recordings from 50 and 60th..

What would the benefit of this amp be over a lower wattage really well made set amp be?  I am really on the fences between the IDA-8 and a not to be named set amp to pair with a set of high efficiency 94db Omega speakers. I really need help pushing me one way or the other. 
Title: Re: IDA-8 ($995) features and spec
Post by: gregfisk on 9 Mar 2016, 04:08 am
I have not heard the Ida-8 and have probably not heard the set amp your'e talking about. So, for me the question to you is how loud do you like to listen? A set amp is going to have its limits when it comes to volume, the Ida-8 will probably be able to go much louder. The Ida-8 is supposed to have a warmish presentation which would be sort of like a set amp but I don't think they will sound the same.

I really like tubes somewhere in my system, but I also like to turn up the music loud sometimes to really get that live concert feel and to be able to hear all that the recording has to offer. If you don't listen too loud and won't, then I would think a nice set amp to be a good choice. The other things you need to think about is the ida-8 does way more than a conventional amp, which I probably don't have to go into as it has been stated many times in this thread already.

If you have a preference for tubes versus solid state you may answer your own question. If you like the idea of an all in one type of amp with all of the additional features then go for the Ida-8.

I have Super V's which are 97db efficient and I am much happier so far with an amp that can control the speakers better and not peter out when I turn the system up but I also have a very nice tubed preamp to add the warmth and texture that I like to hear in my music.

Hope this helps but really you have to decide what works best for you.

Greg

Greg's answer is spot on IMO.

Purchase one or the other to try out. If it doesn't please you, return it and get the other. You might be out $30 for shipping, but you won't wonder if you made the right decision.

Enjoy the moment. Go for one!

Post by: JackD on 9 Mar 2016, 04:53 am
Agree, one is not inherently better than the other just different.  All depends on the rest of your system and your ears.  Try them both or just pick one.  Every ones situation is different so don't listen to the proponents for either side since the only one that needs to be happy with the sound in the end is you.  Plus one amp is not best for all speakers or settings.

Post by: maty on 9 Mar 2016, 11:02 am
Off-topic II

Other option is to play the rips from vinyls recorded analogically, with tubes. Then you have the even harmonics in the rip  :D and yo do not need a tube amplifier (hybrids with Exicon's lateral MOSFETS are better than 100% tubes, with more and very good voltage regulators like AVA amps). The other option, more cheaper, preamps with JFET like NuPrime amps to generate the even harmonics.

Classical and jazz vinyls from 60 and 70 sound very well. The mid-fifties jazz too.

Off course, vinyls from quality labels. And you need a very good equipment to make quality rips: more $$.

set amp versus IDA-8 - tube amp has two things that people like 1) harmonics that give the tube sound; 2) analog sound
#2 as I have pointed out is no longer an issue with new generation of NuPrime amp (even back in 2005 the NuForce amp already sounded very smooth unlike any class-d amp).
#1 is more about personal taste. We can now produce tube amp sound. 
Our class D amp has speed, dynamic, power, resolution that is superior to tube amp.
STA-9 would be like a tube amp without its disadvantages. If you compare STA-9 with a tube amp, you will very likely choose STA-9.
IDA-8 is sort of in between, smooth, warmth, but we didn't go that far with the harmonics like STA-9.

Oh the anguish of making a decision without listening to the options  :?

With no dealers in Australia, although a very helpful one in NZ ......but unfortunately it is still not the same as actually listening to the gear.

I have a pair of KEF LS50's on my desktop and I am torn between an IDA-8 or a DAC-9 + STA-9 combo.

Source files are FLAC, pop, rock, blues and female vocal. Being on a desktop listening volumes will only occasionally be room filling, but never just background.

Really don't want too much gear sitting on the desk which makes the IDA-8 an obvious candidate, but a higher priority is I don't want to miss out on any clarity, detail and musicality,..... just love some of the subtlety you can get in instruments and a lovely voice like Eva Cassidy.

What are the tangible differences that would set the DAC-9 + STA-9 combo apart from the IDA-8 that would help me decide ?

I have experience with both but haven't paired them specifically. The LS50 is a fantastic speaker, but as a bookshelf is still limited in the bottom end. In that regard I would consider the warmer tonality of the IDA-8 to be a better match to help round out the bass.

Agree, I think the LS50's could benefit from a little warmth, but I thought the STA-9 was warmer than the IDA-8 based on the Nuprime comparison amp table http://www.nuprimeaudio.com/index.php/reviews/amp-comparison.html ?

Rustydoglim, would really appreciate your reasoning please for the IDA-8 ?

Another opinion I have received is that DAC-9 & STA-9 combo steps up to another level of clarity and detail.

The DAC-9 & STA-9 combo needs a little more real estate on the desktop and a few more $'s, but would I be missing out on anything sonically with the IDA-8 ?

I'm pretty sure they can be stacked no problem - the DAC-9 and STA-9 have the exact same footprint as the IDA-8 (235 mm W x 281 mm D) - so it's really just down to $ and sound.

As a RULE; When in doubt GO BIG. . .  :lol:

But I think RDL's reasoning is, that as a desktop system, you will be rather NEARFIELD, which will reduce your need for power, AND increase your ability to hear the High End Transparency before it loses energy via dispersion.

So, while the DAC-9 and STA-9 "DO" go up a level, your listening position/proximity will not allow you to use the extra.

That said, if you may "in the future" use the system with a greater distance to the speakers, then by all means GO BIG :thumb:

Either the IDA-8 or STA-9+DAC-9 combo will do well, but as John suggested, if you want the flexibility, then go with the combo. You are going to enjoy the components for years and the difference in price is only a few nice dinners (that turn to shit the next day by the way). So this is definitely money well spent  :thumb:

Thanks Rustydoglim, the extra cost is not really the worry, it is the presence on the desktop.

I am sure either combination would do well, it was trying to get a view (other than longer term flexibility) of what would be the sound profile differences in the two options, such as would the DAC-9 give improved detail over the IDA-8 ?

In the amp comparison table it suggested the STA-9 had a warmer sound profile than the IDA-8, is it significant ? - with the KEF LS50 this could be ok.

Got my IDA-8 and plugged it yesterday.
Now with Gershman Acoustics Avantgarde speakers and feeding from PC from JRiver via USB.
Room is not realy 100% yet, and IDA-8 is not yet broken in - but nevertheless here my first impessions.
Sound of this little bugger is awesome.
Before IDA-8 those speakers where fed with Krell 400xi and OPPO BDP-105 as a source (via DLNA).
What can I say. Some people say that all solid state gear sounds the same. If they are not convinced listening to IDA-8 that they are wrong - they are deaf.
It sounds nothing like previous combo. The only thing similar I heard at home before was conrad-johnson preamp and amp combo (I lost it to flooding 10 years ago), which was probaby 5 times more $$ then. It is hard to compare to something you heard so long time ago, but that was the first thing came to my mind when I turned volume up.

Will report in a week with a bit more detailed report, but so far I am extremely happy.

I am still enjoying IDA-8 -and I think "breaing period" is very smooth, sound quality still superb, did not change signature too much, may be just a tiny bit more clarity added.
Very happy.

Found interesting "bug" (or may be it is just my unit). If you set unit to "mute", it start blinking (as it should). Then turned it off, and when turned ON, it still stays on mute, but without "blinking" indication. Pressing mute again does not help. Swithcing sources back and forth "restarts" the sound.
Not a big deal, obviously, but something that probably needs to be fixed.
NOTE: I am using only USB input at the moment.

A few things to consider:

* The uncluttered desktop whether it be audio/computer/work related is the ideal. That being said the fewer pieces the better, if they are to reside ON the desktop.

* The IDA-8 and IDA-16 from NuPrime very much fit the bill for the new generation of hifi enthusiasts who use their computers as their primary front-end/source for music. Consolidation is key. The inclusion of  a DAC capable of handling hi-res/DSD files minimizes the number of components in the solution. Far less wires/cables.

All this talk of the IDA-8 is making me think i have gear to sell off and pick one up :)

If there is a digital volume control in the MicroRendu or Sonic Obiter, then of course you can control the volume. Additionally, the IDA comes with two remotes.

In this case you are not changing volume of IDA-8 -but volume of the feed. Volume of IDA-8 itself is not controllable by applications, obly volume of digital stream to it.
I am using IDA-8 with JRiver as a player - and I can control using JRiver volume for PCM, but not direct DSD (but it JRiver and driver functionality, and not of IDA-8).

Oldzorki is correct, any external change in signal strength will not change the read out of the volume setting on the IDA-8.

The LED readout of the IDA-8 is telling you what volume level you have selected using the IDA-8 volume control, "not" what voltage strength you might adjust externally from your source.

And yes, if you adjust the external volume of the source, that will also adjust the actual volume you hear.

Some DACS, like the Audioquest DragonFly and exaSound E12, have a USB-based volume control which allows you to control the unit's volume using the system level and the "slider" in whatever app used when playing music. I think this is a pretty rare option in USB DACs.

I think you mixing it up.
With USB you control yet again what is going into DAC, not output volume actual DAC. And it is not rare, but common feature of al USB DACs. You do not control (in this case) DAC volume, just volume of what is going into DAC.
Simple example of analog world -
Imagine thsat you have a preamp plugged into integrated amp (regular input). Then you can control volume of your speakers via frist preamp, without touching volume control of intergated. In our case the source (USB output) is that first preamp.

I just wanted to add a quick  :thumb: to both Nuprime and this forum. I received my IDA-8 a few weeks ago as a single box replacement for a Cambridge Audio Integrated and DAC. I made the swap primarily for aesthetics, but had a feeling the sound would improve as well.

This is for my secondary system in the living room and the IDA-8 has exceeded my expectations. Driving bookshelf B&W CM1s the clarity and bass are both substantially improved. It's making me think about going up the line for future upgrades to my 'reference' system.

Just got the new Sonore MicroRenu player, which is quite remarkable.  I'm thinking about getting a 2nd one for use with my IDA-8.

I know some Dacs have issues playing back from Linux based players on their USB inputs (my Devialet does).  Any issues I should be aware of with the IDA-8?

Thanks

I am using Daphile (linux based headless) with my IDA-8, with no issues.....once I read the FAQ carefully on the Daphile website.   :duh:  I had no volume...but playing with a couple of checkboxes fixed it.

I just wanted to add a quick  :thumb: to both Nuprime and this forum. I received my IDA-8 a few weeks ago as a single box replacement for a Cambridge Audio Integrated and DAC. I made the swap primarily for aesthetics, but had a feeling the sound would improve as well.

This is for my secondary system in the living room and the IDA-8 has exceeded my expectations. Driving bookshelf B&W CM1s the clarity and bass are both substantially improved. It's making me think about going up the line for future upgrades to my 'reference' system.

Hi,
I wonder if you saw this little snippet
Quote
Found interesting "bug" (or may be it is just my unit). If you set unit to "mute", it start blinking (as it should). Then turned it off, and when turned ON, it still stays on mute, but without "blinking" indication. Pressing mute again does not help. Swithcing sources back and forth (C1 and USB for example) "restarts" the sound.
Not a big deal, obviously, but something that probably needs to be fixed.
Is it my unit or common bug? Of course I do not consider it major , but still..

Hi, Zorki.

My wife and I are car traveling this year and I brought my IDA-8 with us. I have been using the Bluetooth input with either music in my iPhone or Tidal streaming. It is so convenient!

How do you pair the IDA-8 with a bluetooth device? There doesn't seem to be any button that puts it into pairing mode, and there's no mention in the user guide...
Thanks!

Audio guy is correct.

The Bluetooth feature has come in handy so many times that I know I will miss my IDA-8 should I ever decide to sell it. I wish I could remove the 100w amp "module" and replace it with the ST-10's or K-38's amp "module". Wouldn't that be cool?

ElemenoZ,

Have you decided to buy an IDA-8 yet, or still researching?

Thanks. I do see that is how to connect the dongle to the amp. My question is how to pair it with a phone or other Bluetooth source. Usually you hold a power button (or something like that) to put the device into pairing mode to make it discoverable by the other device (they don't constantly broadcast that they're available).

It there's no pairing button on the dongle (is the inset logo a button?), then perhaps it automatically goes into pairing mode for 30 seconds or so when it is powered on?

The left-hand dial is the selector switch. Turn it to the E source. Go to your phone, pad, or computer and activate its Bluetooth. Select BTR XXX (or whatever it is). After your device pairs to the IDA-8, you can play music.

The IDA-8 comes with two remotes which may be used to select the "E" function.

Do you have the amp?

I SO wish the IDA-8 could be configured with a digital crossover built in.  It would be perfect for my bedroom system, but I have some very small monitors that are easily damaged if overdriven.  I could live with full range for music, but they would probably get destroyed when watching movies.  I assume the only way a person could use the IDA-8 with a sub would be to run the speaker-level outputs to an external crossover (and deal with the likely loss of fidelity) or run your mains full range and use the line-level to "blend" in a sub for the bottom octave?

Ah yes, that did the trick. It must be discoverable for a time after switching to that input. Was able to pair and send audio from my phone.

Yes @mresseguie I have it. Won't likely use bluetooth very often, though, as I just put together a Raspberry Pi with RuneAudio to manage all my digital audio into the system. It works beautifully.

Bluetooth is nice to have all the same. Thanks for your help everyone.

Actually, it should show up on any of your Blue tooth sending devices anytime the dongle is plugged into the IDA-8, and the IDA-8 is powered up.

Obviously, you will not be able to hear the device until you select the correct input and pair (your device should tell you that it is connected) with the IDA-8.

Also make sure your device's volume control is turned most, or all of the way up, and control the overall volume with the IDA-8 for the best quality.

If you're using a computer as source, you could simply use the EQ to shelf down the bass and not worry about overdriving your speakers.

If blending in a separate sub, most likely it will be powered and will have an adjustable low-pass on it anyways.

Good suggestion as I was not considering EQ to shelf down the lowest frequencies.  Yes, I am using a computer as a source for music.  Currently LMS, but medium term I plan to look into changing that out for ROON.  Movie-based audio, however, is coming from either Netflix or physical disc.  I imagine I can set speakers to "large" in the player but this probably only affects the analog outputs and not the digital.  Since I care about quality on music and convenience on tv/movies (will be better than my tv speakers under any scenario) I suppose worst case I can use the analog outs and deal with the IDA-8 re-digitizing.  I don't want to hijack this thread and will do some more research so thanks for the EQ idea.

Hey guys,

I have decided I'm going to pull the trigger on an IDA-8. The only thing to decide now is weather to pick up a used unit, or a brand new one.

The reason for my post is that I've found a used unit for a good price, but it's an earlier IDA-8 with the 6V RCA outputs. I don't plan on using the RCA outs right away, but I don't want to run into a situation down the road where I find myself wishing for the lower voltage.

I will be running my REL T-Zero sub off of the IDA-8, but my cable runs off the speaker outputs, and not a traditional sub out.

One reason I am concerned is cause I can see a situation where I'd want to pick up another NuPrime power amp and use it for horizontal bi-amping. In that case, what output voltage would be preferred?

Thanks for humoring me. I'm looking forward to joining the NuPrime family.

Yeah, you want the 2V output for another amp.  Not sure you want to just add an amp to the IDA-8, some sort of level matching would be needed.  However I seem to remember something about retrofitting the 6V to 2V output.  Can't really remember anything exactly, whether you could add a resister or something or it has to be sent to the factory, but enough to call a dealer like John Casler and ask.

Cannot say enough about the IDA-8. It has become my go-to recommendation for newbies, specifically millennials who are digital.  Matching the IDA-8 with a pair of ELAC Debut B6 speakers (I wrote about this in another thread) is truly inviting/economical solution, which for some could be all they ever need. Add a decent USB cable and pair of speaker cables (I suggested Audioquest Forest USB and Audioquest Type 2 terminated speaker cables). All this for under $1500. Source can be their computer and/or mobile phone.

To think that the whole lot can be packed up in a piece of carry-on luggage one can take on a plane. Add to this that the voltage is selectable and it can be taken almost anywhere. :)

What's more, upgrade the speakers to ELACs own UB5s and you really do have a system that would've been worth five figures a decade ago.

My IDA-8 came with two remotes - one is 'regular' looking and the other is 'credit card' style. I don't use the regular looking remote because the battery dies within days. I use the credit card remote. The battery lasts for months. I only experience issues when the battery is low. I replace it when this happens.

Change the battery or use the other remote.

Are you directly in front of the amp or off to the side?

As with "any" computer, there may be an occasional blip.

Try un-plugging and then plugging it back in, and allow it to reboot.

I had this happen once on mine, when I left it on all the time, rather than powering down.

It is my thought that living where I live, some stray, strange command may have caused it.

But, try shutting down via rear panel switch, un-plugging for a minute, then powering back up.

I would also suggest powering down after each use.

I think you may have misinterpreted my response.

I am not aware of a single other event as you describe by any other users, and the one I experienced was "only once".

So, if your issue is continuous, then it is likely a "one off" malfunctioning unit, not a normal one.

My suggestion was a "try this" suggestion, since I have seen processors in AVR's, Bluray Players, Streamers, Servers, and other more sophisticated components, on occasion reboot to no further issues.

In these cases, there could be any number of causes, like temporary power failures, stray IR signals, voltage spikes of drops, etc.

My suggestion to "power down" when not in use, was under the possible issue of powerline or voltage vacillation, that could be the problem.  If power stops or drops, it is like turning your computer "off and on" quickly so the the reboot fails.

If your unit doesn't respond, or continues to be "fiddly" it should be looked at and repaired.

I don't have a IDA-8, but a HD-AVP and there are several (at least 5) remote commands that do nothing.  I looked at another HD-AVP and that one worked 100%, so for some reason the IR receiver is faulty, or there is an unknown hardware problem.  I did report it but had no feedback so far

Hey guys and gals. I just got my IDA-8 from John/FedEx today and I have it hooked up and playing. I'm curious about a couple things from other IDA-8 owners.

1. How long does the NuPrime need to burn in? I think I'm hearing a little digital edge on it right now... but I also just put in some brand new 1M Clear Day Shotgun speaker cables at the same time, and being 100% silver and since I've had lots of Paul's cables before (including my entire main system) I know they need some time to settle down. So that could be compounding what I'm hearing a bit. I'll let it play continously until Monday+ to burn them in and the amp.

2. Plugged into my iMac via USB (I assume USB is the preferred digital connection on the desktop? I could use optical instead) this DAC doesn't fix the output volume of my Mac... do you guys max out your computer volume and then just use the volume on the IDA-8? I am using the Tidal desktop app currently to stream. It's volume is at max as well.

"Burn-in"
I don't think it is Nuprime specific.
 I like to leave gear on and off in long cycles for about a week before making snap judgements. Another words 5-10 playing sessions of several hours along with sessions of gear turned off.
Playing continuously is good, but the off time is good too IMO.

I maximize volume on my  mac everywhere, and  would use the IDA as volume control with the full strength signal.

I'd highly recommend something in between the iMac and the DAC to clean up the power and reclock that USB output.  Wyred Recovery is my preference over the Uptone Regen, but Regens are abundant used these days and can be had for around $100.  Well worth it, but they do respond very favorably to higher quality power than what their wallwarts supply.  But even with the cheapo wall warts powering them, these units will significantly clean up that USB signal and remove a good bit of digititus. 

Another option would be the new generation of XMOS USB to SPDIF converters - this one is externally powered so as to be able to provide it clean power from a non-computer source: http://www.diyinhk.com/shop/audio-kits/111-xmos-192khz-high-quality-usb-to-spdif-with-ultralow-noise-1uv-regulator-wmanual-power-switch.html

While the F-1 unit is powered by USB bus: http://www.ebay.com/itm/F-1-XMOS-USB-Digital-Interface-Module-XU208-U8-upgraded-version-/111961717820

F-1 will not sound as good if powered by your computer-based USB bus.  I have one, and it works great, but it's getting clean power through a HDPlex LPS powered microRendu.  In this configuration, the F-1 does things that the WfS Recovery can't in further improving the signal of the USB output of the microRendu.

Title: Re: IDA-8 ($995) features and spec
Post by: Ictwoody on 25 Aug 2016, 07:50 pm
Hmmm... a reclocker is something I've been curious about, perhaps I'll give one a try. So you think that the USB input into the NuPrime is definitely the preferred input? Is the included power supply with the Wyred adequate? Or do you like an upgraded power supply there as well?

- Woody
Title: Re: IDA-8 ($995) features and spec
Post by: genjamon on 25 Aug 2016, 08:03 pm
Power supply upgrade on the Recovery would definitely help, but I thought its stock supply was definitely good enough to hear solid improvement over the Regen with an LPS. 

I don't have the Nuprime, and can't comment which input is better.  I can only tell you the F-1 with new generation of XMOS USB input circuits is doing good things compared with the microRendu straight into my Lampi Big7's USB input.  I'm interpreting that result to indicate the new XMOS circuits are better than the USB input circuitry Lampi has in my 1year old DAC.  Could be worth trying as well, but a lot of folks are liking these units compared with even highly tweaked/refined USB signals.

I don't want to derail the thread with USB tweaks or anything, but in my experience getting noise out of the digital feed and careful reclocking are critical to getting rid of digititus and creating realism in digital reproduction. 

I also agree that time on the cables, and burning in the unit itself could help your initial complaints - in addition to the above.

No complaints. Just EARLY observation. I'm going to run this thing in for 100-150 hrs and then listen critically. There's a lot of variables at the moment so I won't be jumping to any conclusions.

I sent you a private email mentioning this, but will post here too.

Going to a new more detailed and transparent  component, and adding highly revealing Silver Cables at the same time, might be what you are hearing.

Silver cables have a more detailed transfer, and take a while to settle down or bloom.

From an input/decoding standpoint is there any reason to prefer one input over another on the IDA-8?

Here in my office I pretty much never play super high res files... in fact... most of the time I'm just streaming Tidal or listening to podcasts. So perhaps in my situation Optical might be the simplest way to get the 1's and 0's into the NuPrime.

You'll get no debate from me that it's a rabbit hole.  But I'm pretty sure Toslink connections have their own liabilities.  And there are cheap and easy ways to do some basic isolation and/or reclocking in USB - you don't have to go deep into the rabbit hole if you're not as curious as Alice.  IME improving your digital supply can be as significant as a major component upgrade.  If the Nuprime is of sufficient quality, and from those of you on this thread it does seem like it is, then it will benefit greatly from attention to digital supply.

Optical (Toslink) has limited bandwidth.....because it is an inferior / imprecise signal transmission system. It's fine for non-critical applications.
Title: Re: IDA-8 ($995) features and spec
Post by: srb on 26 Aug 2016, 05:02 am
Toslink is limiting for two reasons:  (1) The signal undergoes dual conversion - first on the transmitting end from electrical to optical S/PDIF, then on the receiving end from optical back to electrical and (2) It was designed as an inexpensive S/PDIF link for consumer disc players and no high-precision transceiver modules exist.

When Stereophile and other test labs test for jitter, the optical output almost always has much more.  Is this just a measurement thing and not really audible?  I don't think so.  Subjective listening on sources with both coaxial and optical S/PDIF 4 out of 5 times sounds to me like the coaxial source is more in focus and the optical is blurred a little, to use a photographic analogy.

Given a computer or streamer with a PCIe slot with more direct connection to the processor, my preference would be a soundcard with coaxial S/PDIF or AES/EBU outputs.  As this is not possible on a laptop or slotless mini computer, you have to go with what works best with what is available (USB or optical).

USB implementation varies widely, with some hardware giving good results stock while some others require external device bandaids.

As far as optical, the previous recommendation for Lifatec Toslink cables is a good one.  I'm not sure about huge advantages over short lengths given the state of Toslink transceivers, but it eliminates any doubt of the cable adding problems and you're only paying an industrial parts premium, not an absurd audiophile blue sky premium.

I've seen too many problems (dropouts, etc.) using Toslink to mini-Toslink adapters that I won't bother with them.  Get the properly terminated cable to start with and forego adapters.

1. How long does the NuPrime need to burn in? I think I'm hearing a little digital edge on it right now... but I also just put in some brand new 1M Clear Day Shotgun speaker cables at the same time, and being 100% silver and since I've had lots of Paul's cables before (including my entire main system) I know they need some time to settle down. So that could be compounding what I'm hearing a bit. I'll let it play continously until Monday+ to burn them in and the amp.

Why silver cable? We never like silver unless the component is "dual". Since our components are all neutral (when we say it is a little warmth, it is just a little, not like distorted type of warmth), you might get edgy sound with silver cable.

You should set the digital volume on computer at max.

I like the clarity of silver. I use these cables in my main system, and I have used Clear Day cables in other systems including my office. I find Paul's (Clear Day) cables to not have as much of that silver, overly bright, sound that I've heard with other silver cables. I find them open and detailed. Once I've got a couple hundred hours on everything I'll consider a change if I think they are a bad match. My Audience speakers are very detailed, and the amp is plenty detailed... so they might prove to be too much. I might give a set of Audience's own Ohno Speaker cables a try to go back to copper without spending a wild amount of money. I think a 1m set of their cables is about $200 and by all accounts they are very good.

So, your product is electrically disconnected from the 5V bus in a USB cable, provides a measure of resistance and/or galvanic isolation in the ground plane, and provides high quality reclocking of the data lines before feeding into a USB receiver module?  And more?!  Interesting!  I think may prospective customers would be quite interested to know more details about all of this!  There are lots of us who have gone to great lengths to try all these tweaks, and it would be wonderful to find a product where those tweaks didn't matter because it was all handled well internally. 

And I also kind of resent the implication that I'm not a potentially interested customer.  Honestly, I was starting to get pretty intrigued by this product, but the attitude implying that I don't have a genuine interest in this post has me turned off a bit.  I was just replying (I thought helpfully) to a fellow forum member's question about small tweaks to consider in optimizing his new setup.  I saw he was running straight from a consumer grade unoptimized iMac into your device, and I know from experience with several of my own setups as well as those in my local group that this can be a huge source of noise in the system. 

Of course, if you were to explain more about what specifically the IDA-8 does in terms of replicating features of many of the tweaker products, that would go a long way to restoring my interest.  It's one thing to simply say with braggadocio that you do all that and a kettle of chips, but its another to actually explain to a customer base what you're doing.  Some of us want to peer underneath the hood before purchasing. If you're actually doing all you say you are, that only greatly increases the bargain your product represents.

Fair enough.  But now that you've broached the subject, I'm curious which of the functions I mentioned above your device accomplishes.  Breaking the 5V connection?  USB ground wire galvanic isolation?  Reclocking of the USB packets before processing into a different data stream and sending to DAC?  I'm honestly very interested.  I've been looking on and off for quite some time at options for upgrading a secondary system for my TV and media server room, and your unit could be exactly what I'm looking for.  But I'm weighing different options.  This information could be highly influential in my decision-making process.

Actually this is by design to conduct heat to top of the amp. Other designs either trap the heat inside (even with ventilation holes it is not efficient), use fan or conduct to the bottom (so that customers don't complain!). But the best way to dissipate heat without using a fan is to have heat sink inside, then further conduct the heat from heat sink to the case.  Sure the amp might gets hot, but the board will last longer.
Title: Re: IDA-8 ($995) features and spec
Post by: Armaegis on 31 Aug 2016, 04:18 pm
even with ventilation holes it is not efficient

Sometimes, vent holes actually make heat dissipation worse which is quite the opposite to intuitive thinking. While hot air does naturally rise, its overall movement is incredibly slow. When the air doesn't move, it is essentially an insulator. In some cases (I'm generalizing; not saying specifically it's the case here), the closed chassis provides more metal surface which helps spread the heat over a wider area, which can be more effective than putting in vents.

The whole thing devolves into a mathematical/finite element analysis. One approach may have greater dissipation overall, but higher concentrated heat. Stacking affects venting. Dust and grime are factors. Etc etc.

Thoughts on the difference between the IDA-8 versus the STA-9/DAC-9 combo?

A few pages back Rustydoglim advised the IDA-8, but that was for a near field computer system. I plan on using these to power a Zu Druid MkV; a very efficient speaker, which actually benefits from extra power per both reviews by 6moons.

My old amp (redwine audio 30.2 LFP) died so I am currently driving them with one of the original nuforce Icon amps and am quite impressed with how well this little amp drives them. The lower end is quite nice but it seems a little harsh. I do appreciate a warmer sound overall.
Title: Re: IDA-8 ($995) features and spec
Post by: rustydoglim on 12 Oct 2016, 07:56 pm
If you have very high efficiency speaker, and also impressed with Icon amp, you might want to wait until late November/early December for IDA-6 ($649 or $599, t.b.d).  The sound signature is sort of between IDA-8 and STA-9 (which is what I think you will like), has 30Wx4 or 70Wx2 (configurable).  It is a new entry level high-end integrated. It won't be as good as IDA-8, but something I would strongly recommend for people who want to drive a < $1K speaker, ceiling speakers for multi-room installation (that's what the 30Wx4 is for), DIY project.

Bhazen,

What's the sensitivity of your LS3/5A speakers?

If they're in the 83 to 84dB sensitivity range, the IDA-8 isn't powerful enough unless it's a small bedroom. I've got a pair of Fritz Loudspeakers LS5/R 83.5dB speakers that sounded okay with my IDA-8, but really needed 150 watts/ch (or more) to truly sing.

So I haven't read all 22 pages of this thread so it might have been talked about but is anyone using the IDA-8 in a mutimedia system? I use my two channel set up for everything. I don't have the luxury or space to have a dedicated listening area. So if you have used it in a 2 channel home theater application how does it sound? I am currently running a pair of Omega Supercharged 3XRS's with a Decware SE84UFO. And I love the combination for most things but I do feel like it runs out of steam and starts clipping at higher volumes on higher demanding and dynamic material.

I'm using the IDA-8 driving some KEF LS50's which are 85 db sensitive. While the IDA-8 does drive them, and sounds good doing so, these speakers are really happier with more power. I'm currently using this setup in a camper. I offer this merely as one bit of data input. I've only had the IDA-8 a little over a week and I think it's the best audio bargain out there. But, I plan to find a better speaker match for the amp.

I just ordered one of the demo units from Audio Advisor.  I'll be driving Klipsch Chorus II's in a large room (16x32x12) and in that system started with a Pioneer VSX series AVR and currently have an NAD D 3020.  I'm looking forward to hearing what the IDA-8 can bring to the table.

I read through the thread and am I understanding correctly that at some point in production the output voltage at the line out changed to something less than 6v?  If so, is there any way to tell which one you have?  Serial number or some other marking somewhere on the unit? 

Also, I plan to use RCA cables out of my ATT uverse cable box into the analog inputs of the IDA-8 but read that some are having trouble with this.  Would taking a optical line out of the cable box and going into an outboard DAC and then using the analog outs from the DAC into the IDA-8 eliminate the signal gremlins that cause the issue others have had when using the analog output from a cable box to analog input of IDA-8?

What you are calling an 8" USB cable is likely part of the dongle.  There should also be a Receiver portion, that connects to that cable and then the cable plugs into the rear of the IDA-8.

Search your packaging.  If it is a used unit, it may not have been repackaged well.  If it is not there, contact your retailer.

I got a chance to spend some time with my -8 this weekend and can say I'm very pleased with its performance. To say it's an improvement over the NAD D 3020 it replaced would be a gross understatement. However, I do have an issue and I don't think it's normal...when I power the unit up I get a pretty loud "crack/pop" in both channels. I'm assuming this isn't normal.  The speakers are 101 db sensitivity, but the NAD and Pioneer AVR that preceded the -8 didn't do this with the same speakers.
Title: Re: IDA-8 ($995) features and spec
Post by: John Casler on 14 Nov 2016, 06:04 pm
The "crack/pop" is normal and hardly noticeable on most speakers. in most systems, it might be akin to the crack/pop one might hear when playing an old record album at normal volume.

 It is hard to tell if yours is "out of the norm", since your speakers are super efficient.  I doubt it is damaging in any way.

I just tried it on my system (with 89db speakers) and turned it on and off at FULL VOLUME, and it seemed to be the same at all volumes.

The pop on the IDA-8 is a little loud on sensitive speaker (91db) but not more than playing drum music.
We can add a filter to get rid of the pop but you might not like the sound.  We had one person who did that and regretted it and we have to remove it for him (that's two round trips to the shop and it cost us $$$). So we rather that you live with the pop, it is not going to harm your speaker.

many NAS like Synology have the internal setup to add a DAC via USB and stream from the NAS direct to the DAC using a program like DS-Audio that will detect an Audio device (USB Speakers) and you can use that to play. It may or may not with depending the software to support formats like DSD/DSF etc

Hello friends,

I'm really craving to hear what a better DAC-AMP does to my system.  I currently own the NuForce DDA-100, and the IDA-8 seems like an almost perfect solution.  I have two questions though:

1. I have Totem Acoustic Rainmakers (4 Ohm, 87.5 dB/W/m).  Would I actually be able to hear the better amp on the IDA-8, or are my speakers way below the better resolving characteristics of the IDA vs the DDA?

2. I love my current connectivity which is:
Unfortunately, the IDA-8 has only 1 Optical in (I really think this is the one point where the design of the IDA-8 is lacking :( , as the next models that have two inputs are the DAC-10 and the IDA-16).  My question is: would a cheap optical -> coaxial hub work well or will it degrade the quality of the sound?  Are there any other obvious combos I am missing?  I would like to avoid hooking the AE via analog cable and move the DA conversion to the inferior DAC on the AirportExpress :( .

Thanks for any feedback!
Best regards,
Rafa.

Optical to electrical conversion has to be done ANYWAY, so it is ok to convert optical to coaxial (get a highly rated converter on Amazon) outside of IDA-8. Currently the two optical inputs on DDA-100 get converted onboard to electrical SPDIF signals.
With the limited space, IDA-8 choose to have 1 coaxial + 1 optical instead of two opticals for better performance (good CD or Blu-ray players have coaxial output).

IDA-8 is noticeably better than DDA-100 in every way. DDA-100 was designed 4 years ago :)

I have no doubt that IDA-8 is noticeably better, the question was: will my speakers be able to show that difference or will it be lost due to the entry-level (so to speak) of the speakers?

Also, given my setup, will the new IDA-6 not make for a better choice?  What will I be sacrificing? (other than keeping a couple of hundred bucks on the bank ;) )

Thanks again,
Rafa.

I have not heard your speaker so can't comment. I know not to judge the sound quality simply base on price. But I think with a better amp and DAC, you should be able to hear the difference. Most US dealers and online stores will allow you to return for full refund.

Here's the sound quality if I have to rank them:
IDA-8
IDA-6  (use similar to STA-9 amp design)
DDA-100

So I think upgrading from DDA-100 to IDA-6 is good, but not worth the effort.

Post by: RafaPolit on 13 Dec 2016, 11:09 pm
Completely agree about not judging by the price.  Speakers are great, and the best I could afford. Just unsure if they are already out resolved by the amp or if there is room for a better amp to justify the extra cost.  But I agree that perhaps the IDA-6 could be too closet to justify the change.

Not in te US though. So trial and testing is not as straightforward.  Still, the local NuPrime supplier is a great guy,
I'm sure we can come with a solution.

Hey all, I've had my IDA-8 for a year now and love it. Looking for recommendations on a front end streamer that has a solid Tidal app. Don't need a DAC since the IDA-8 has it already. Something like the Bluesound Node 2 ($500) to the Lumin D1 ($2000) is my range.

Love to hear your thoughts on what should pair well.

Post by: JackD on 14 Dec 2016, 07:01 am
I would forget the  Bluesound and it's quirky app if I were you.  The Lumin D1 is a really good option but needs the $500 Sbooster power supply to reach it's full potential.  That leaves you with the Auralic Aries Mini and an LPS for about $700 or the Auralic Aries for $1500. I have tried the Bluesound and sent it back and own the Aries and the Mini with LPS.  With the upgrades in the Auralic software and firmware over the last several months the sound between the two is so close that I would buy the Mini and an LPS.  If you don't want to spring for the $300 Auralic power supply there is one on EBay for less than $125 that has been around for several years and works like a champ.  If you are going to use USB then the Wyred 4 Sound Recovery will also help improve the sound.

Hello friends,

I'm really craving to hear what a better DAC-AMP does to my system.  I currently own the NuForce DDA-100, and the IDA-8 seems like an almost perfect solution.  I have two questions though:

1. I have Totem Acoustic Rainmakers (4 Ohm, 87.5 dB/W/m).  Would I actually be able to hear the better amp on the IDA-8, or are my speakers way below the better resolving characteristics of the IDA vs the DDA?

2. I love my current connectivity which is:
  • TV -> Optical Cable -> DDA-100 OPT-in 3
  • AirportExpress -> Optical Cable (miniToslink to Toslink) -> DDA-100 OPT-in 4
Unfortunately, the IDA-8 has only 1 Optical in (I really think this is the one point where the design of the IDA-8 is lacking :( , as the next models that have two inputs are the DAC-10 and the IDA-16).  My question is: would a cheap optical -> coaxial hub work well or will it degrade the quality of the sound?  Are there any other obvious combos I am missing?  I would like to avoid hooking the AE via analog cable and move the DA conversion to the inferior DAC on the AirportExpress :( .

Thanks for any feedback!
Best regards,
Rafa.




I have Totem rainmakers and just purchased the IDA-8.
My previous setup, I was using a Sony HAP S1 to drive the Totems.

I am not an advanced audiophile so lack the flowery vocabulary to describe the difference but the upgrade to the Nuprime IDA-8 has dramatically improved the sound from my Totems particularly in the mid-range which used to sound a bit muddy.

A pleasant surprise is that the Nuprime is fully compatible with the Sony HAP-S1 via the USB port.  So I can continue to use the music stored on Sony drive as a high resolution source for FLAC and DSD files.

I think it is still several months before Tidal is added to Nuprime WR-100 ($99), that would be ideal for you (cheap and plug directly into IDA-8 with a single wire for power and SPDIF data).

There is no phono stage for IDA-8, you have to use HPA-9.

Hello,

Considering currently a new system. I was wondering whether there would be a way to achieve this set-up / functions:
- IDA 8
- WR-100
- Bluetooth streaming

I see I can have for sure WR-100 or Bluetooth but both at the same time I don't see how unless through an switch?

I would use bluetooth mainly for stream live audio from my PC (youtube, videos, internet), maybe there is a way to do so through Wifi? Can the WR-100 be considered as a souncard by windows? (I used to use such a device produced by Azurewave)

Thanks for your help!
Title: Re: IDA-8 ($995) features and spec
Post by: srb on 29 Dec 2016, 10:28 am
While the WR-100 can apparently be connected to the IDA-8 E4 extension port for both power and data, it also looks like it could be alternately connected via the S/PDIF optical output (if that input on the IDA-8 is not needed for another source) along with a separate external 5VDC @ 1A power supply.

Hi Steve and thanks a lot,

Indeed, there is this possibility, I was planning to use the optical input for the tv, but a set up can be done with a optical switch or optical to coax converter. I suspect however that it would be of a lower quality than the USB input (maybe risk of jitter).

Title: Re: IDA-8 ($995) features and spec
Post by: srb on 29 Dec 2016, 12:41 pm
Another possibility might be to connect the WR-100 to the E4 port and add a third-party Bluetooth adapter with coaxial S/PDIF output such as the Yamaha YBA-11 (http://usa.yamaha.com/products/audio-visual/accessories/yba-11_w/).

It too would need a small power adapter (5VDC @ .5A).  I know the IDA-8 already comes with a Bluetooth dongle, but if some kind of small accessory device needs to be purchased one way or another .....

The type-A port for bluetooth dongle and WR-100 is not USB, it is simply S/PDIF, which is essentially the same as coax.
Using the optical output from WR-100 should be ok, not worst than coax in such a short distance.

I finally got around to trying out a few subs with my 1x pre out gain equipped IDA-8.  With an older AR 120w 12" sub I have to adjust output to around 70% to get to a level that's appropriately matched to my Klipsch Chorus II mains (101 db sensitivity) and with a pair of 100w Pioneer SW8-MkII subs I can't get them to match up with the mains even at full output.   I'll be using a pair of 12" DIY subs in the near future (300w plate amps for those should arrive next week) and I'm thinking they may have a better shot at getting to appropriate output without having to set the volume as high as I do on the 12"/120w  AR sub, but my concern is this...I will be running a DSspeaker Anti-mode digital room correction/bass management unit with those subs and my experience with using that DRC unit is that after it performs its filtering the sub gain has to be turned up to get to the sub(s) output to match the output prior to the application of the correction filter.  If I find I don't have sufficient headroom (at plate amp ouput) to accomplish this will I need to send my IDA-8 in to have the preout gain increased?  I should add that I intend to try the pre-outs for an outboard amp as well and the amp may or may not have adjustable gain.

Alternatively, you can try a small gain device inserted between the dsp and the sub amp (like an active DI box).

It would seem that the "efficiency" of the Klipsch make you use a "lower Volume setting", so the voltage to the RCA outs is reduced.

Your options would then be:

1) Use less efficient speakers, or place a device in front of the speaker to reduce it's efficiency
2) Send the IDA-8 in for 2x or 3x voltage output
3) Amplify the RCA output to the sub

I was under the impression that the voltage at the RCA outs is fixed.  Is it actually variable with a maximum value (2v in my case) reached at a certain volume setting?

And would option #3 be accomplished with a device such as the active DI box suggested earlier?
Title: Re: IDA-8 ($995) features and spec
Post by: John Casler on 24 Jan 2017, 07:59 pm
Yes, RCA output voltage is variable with Volume Setting.

So, because your Klipsch require such a low setting the subs get a lower signal.

Questions on the Display On/Off setting:

1. If the display is off, does it turn on temporarily when a volume or input change is made, and then go dark again?
2. Is the display on/off setting stored in memory, like input volume? If I turn the display off, will it stay that way even after powering off/on?

Perhaps the better question is whether that high res you're buying isn't just a regular file that got resampled or even remastered along the way.

But really now, all music goes through many many adc/dac processes before it's even pressed into final copy. As long as each stage can process at the required level, you shouldn't be losing anything. 
Title: Re: IDA-8 ($995) features and spec
Post by: RafaPolit on 2 Feb 2017, 05:03 am
I, for one, believe that pixelmixture's question is relevant and an interesting discussion.

If the hi-res files are or not really hi-res is a completely different discussion. Let's say they are, or at least will be at some point. Then, his question still stands unanswered!

I do believe that not being a 'true' analog amplifier, that re-digitizing could prove prejudicial. At least, a good computer using all its power to down sample to formats that the IDA-8 could understand may be a better resulting sound that the analog signal being digitized back by the ida.  This would take the meridian out of the equation.

Another route would be to get a true analog amplifier that does not re-digitize the signal.  That may prove more expensive, as it is taking the ida out of the equation, but buying new equipment.

If option A is the route, you would need to make sure that the best posible downsampling is being achieved.  If you leave it to a less-than-best algorithms, then you will ciertainly be loosing a lot of the hi-res files.

Good luck, let us know which route you took! Best regards,
Rafa.

most of these hires files are resampled files ... i know it ... but i also have hires files that i'm sure are not resampled ...
i was in the process of doing a blind test to see if i can really ear the difference between hires and CD quality ( macmini + meridian dac + ida-8 + sonus faber venere 2.0 ) than i realised that the IDA was digitizing what my MQA compatible dac was outputting ....

Well, my used NuForce dda-100 died on me yesterday.  I brought it to the local distributor (who now carries NuPrime and is no longer carrying NuForce, as would be expected) and he is offering me a full refund on the dda-100 if I buy into an IDA-8.

Sounds like a good deal (although after local taxes the price is quite a bit above US MSRP).  So I am really deciding if I can and should put an extra US$1.500 (that's what it costs here) into the upgrade.

Obviously, the better AMP is a clear advantage.  I am worried about a couple things, some are not much of an issue, others could be deal breakers, so any input is really appreciated!

1. I have concerns about the Toslink input, of which I actually need two, as I have a Samsung TV and and airport express hooked optically to my current setup.  I would be using the toslink for the TV and using the Airport Express with analog until I can find a toslink to coaxial convertor (which I cannot find locally).

But I found this discussion: https://www.computeraudiophile.com/forums/topic/26486-an-almost-comprehensive-nuprime-ida-8-amplifier-review/

Will I be able to use to actually USE the toslink or will it fail to acquire both my TV and my Airport Express?  What use is there in having equipment that is "... designed for high precision devices and we think that some Apple TV devices (this has been discovered with Airport Express) send lower level SPDIF signals then IDA-8 can sync up with..." if I cannot hook the standard equipment it will be used with?

Can someone confirm or deny using the toslink with regular home equipment and being able to work with it?  Or will it only work with 5K CD players?  I am really concerned here! :(

2.  My main source of Hi-Fi audio is a Raspberry Pi3 connected via USB to the USB B port.  This has worked flawlessly on my dda-100.  But again, here comes the 'very high class' USB on the IDA-8 that may or may not work with Linux, as talked everywhere.  Has someone had success connecting the Pi3 (specifically running Moode OS) to the IDA-8.

I am already sacrificing one toslink and would switch to analog from the airport express, and I am willing to sacrifice that for a better more fuller sound, as described everywhere.  But if EVERY input I intend to feed to the IDA is NOT going to work, then what's the point?

Please, help!

Thanks in advance.  Best regards,
Rafa.

we haven't heard complain about Apple's optical output to IDA-8 for more than 6 months, but that doesn't mean it won't happen.
The last time (about a year ago) when someone had this problem, he solved it by using an optical to coaxial converter. Basically if the optical signal is too noisy, IDA-8 can't sync with it (something like that, I don't know the technical details).

After reading The Absolute Sound review and as much as I could find online about the IDA-8, I bought it without an audition.  I had been set on a Music Hall a15.3 to go with my KEF Q300's and Project Carbon DC, but after burning in the IDA-8 and speakers together, I will not likely buy another amp again.  The sound is so good it reminds me of my first system (Pioneer tube amp, Avid 103's and Techics table -- OK, I am an old-timer -- I was in my 20's when I got that system in 1972).  Great new technology and the analog preamp is just the ticket even with the subsequent digitizing it sounds better than the other Class D digital amps I have heard.  The NuPrime IDA-8 is highly recommended by this dinosaur.

Even though the Analog Outputs are labeled SUB, they are "full range" so yes the IDA-8 preamp/dac/volume control can be used with another amp.

Here's what I did yesterday. [After reading my description (assuming my meaning is clear), please tell me if I've done something wrong or if there is a work-around.]

I'm auditioning a new R2R Ladder DAC. It is connected to my Mac Mini (late 2012/OSX Yosemite version 10.10.5) via USB. The DAC is connected to my IDA-8 via RCA ICs. Firmware is Amanero, but I don't know which version. It was uploaded to the DAC last night.

The sound comes out scratchy and bright. It's really unpleasant. I borrowed my sister's cheap Windows PC to use as source and there is no problem. Music sounds great!

What's going on here? Anyone?

I'd appreciate any thoughts.

I think the input stage tops out at 2V? (we'll have to wait for Jason to confirm)
So if you're overloading it, that certainly explains the poor sound and why the PC has no issues.

Is there a way to drop the output level on the dac? Or at least test by dropping the level in your playback software if possible. If that works, then you know the culprit.

Thanks for your idea. Based on other Denafrips DAC owners' experiences, it seems to be an Apple OSX and/or USB issue. Sometimes it is correctable by making changes in OSX versions; sometimes not. There is a known issue with 2014 USB settings(?) in Mac Minis.

I'm going to try connecting it to a brand new MacBookPro next week to see if it is compatible. Really, this whole experience is frustrating. I'm tempted to run out and buy a cheap Windows PC because I know it will work without a hitch. A new MacBookPro will set me back a helluva lot of cash.  :duh: [I had intended to buy a MacBookPro for other reasons before this happened.]

[Edit]
I decided it must be something to do with settings somewhere in my OSX, so I peeked into my 'Audio Midi Setup' 'Audio Devices' toolbox. Nothing appeared to be wrong, but I clicked on Combo384 Amanero anyway just to poke around. The format was set to its highest setting of 768000Hz. CD quality is 44100Hz, so I selected this just to try. Well, what do you know? My issue is fixed.
Now, I assume my output is limited to a max of 44.1kHz with this setting, but there are other settings which I can experiment with.

I've adjusted the format to 192000Hz with no discernible ill effects.

Congratulations, looks like you have got the issue nailed. I had always used Windows and had always set it to 192k. Well, it seems OIS is also same. Good thread to follow as I had just bought ida8 and sp one combo for my son.

Hello,

IDA-8 owner here for over 2 years - great product

My question is I am considering purchasing a Bryston BDP-Pi digital file player and just wondering if there would be any issues with connecting it to the USB input on the IDA-8.

Thus far I have only used the Coax and Optical and I would like to utilize the USB input as the Toslink on the Bryston is limited to 24/96 while the USB and Coax are good for 24/192.

I already use the Coax input hence the desire to connect the BDP to the IDA-8 USB.

I am not computer savvy but I do believe the Bryston is running a modified Rasberry Pi hardware utilizing Bryston specific (Manic Moose) Linux firmware.

Any direction would be appreciated.

Eric

Don't know about any issues (and it is standard so there should not be) but (as you noted) Bryston has proprietary software. There are over 100 pages of posts on one topic alone - http://www.audiocircle.com/index.php?topic=119878.0     I've seen it but never used it.

I recently purchased a lightly used IDA-8 for the desktop system.  I use it with JRiver which I don't find overly difficult (I set up a friend about a month ago with a Musical Paradise DAC in minutes).  I downloaded the driver and hooked it up.  I have a couple of other (Windows 10) music servers in secondary systems and a Lumin U1 in the main system.  I do burn discs and extract DSD files on the main PC so I wanted something decent to hear music (the IDA-8 exceeded my expectations).

Setting it up with a computer usually involves at least having a display to start up the computer and then select the program (e.g. JRiver, Foobar, etc.).  With something like JRiver there are Apps that let one connect to your network and select the music without needing to look at the display.  Keep in mind something like the size of the display on the BDP Pi.  My Lumin has a display that will show the artist and song but one probably has to be within 8 feet of it to read it.  I use the Lumin App on my iPad mini (and I find their App very easy to use).

If one doesn't want to deal with computer issues, I assume you intend to hook the music server to a hard drive vs. an NAS?  Knowing how you intend to store music would be of help.  There are music servers with storage within (e.g. Aurender).

Why bother? NuPrime makes a Pi-9 product currently available for pilot release.  See the topic on Raspberry Pi in the NuPrime circle. It will be listed on www.nuoem.com under Custom section later this week. It has full support but not widely released.

That is true.  If you use the RCA Analog Inputs the signal will be digitized through an ADC, so in theory you will be performing DAC to ADC to DAC.  No advantage to that.

Use the DAC-9 instead.

I have the IDA6 with a dongle but it would be no different from IDA8 for this question. You have a few options:
- NuP WR100D .... havent done this yet
- Raspberry PI with a Allo Digione and connect it to the IDA (and use VolumeIO)
- Airport express has a 96/24 optical out and is an airplay endpoint
- Chromecast audio has a 96/24 optical out (my most used streamer)
- NuP has an alpha Pi case + uDSD dac solution (search the threads)

The Dongle is for Bluetooth devices.

All you do is plug it in, and cycle through the INPUTS and select the "E" input of the IDA-8

Then on your Bluetooth device, search for the NuPRIME BTR-8 and SELECT it.

Play some music on your phone or tablet, and it will be transmitted to the IDA-8.

Post by: ripeart on 26 Feb 2018, 07:44 pm
Thank you. I see. The marketing text is misleading.

"... DSD 256 with the convenience of wireless audio in a small, handsomely designed..."

So in this context wireless means "Bluetooth" not Wi-Fi. I also see this statement: "– Extension port for Bluetooth dongle (included) or future release of optional Wi-Fi dongle"

Do we have an ETA for Wi-Fi implementation? Also, what's the fidelity like over bluetooth? (I suppose I could just hook it up and listen!)
Title: Re: IDA-8 ($995) features and spec
Post by: rustydoglim on 2 Mar 2018, 04:06 am
I should change the text on IDA-8 product page.
The WiFi receiver is the WR-100D, shipping for months already.  The E port provides S/PDIF signal as well as 5V power, so you can just connect WR-100D directly to IDA-8, without using external 5V adapter for WR-100D.

Does anybody have any experience of this amp and Focal speakers, specifically the Focal Electra series? I've read that this amp is neutral with a slight warmth which I'm thinking may be a good match.

Thanks for any thoughts!

Post by: mresseguie on 6 May 2018, 03:21 pm
Which model do you own - 1008, 1028, 1038?

The 1008’s sensitivity is 89dB, so that’s not a concern.

I’ve owned the IDA-8 for about two and a half years now, and I’ve tried a dozen or so speakers with it. I think it’s best suited to speakers with sensitivity in the 85 or 86dB to 91(?)dB range. Higher sensitivity and very resolving speakers tend to sound a bit thin with it. Low sensitivity speakers don’t quite wake up and sing with it.

I really like pairing my 87dB Adelphos two-way monitors to it. The IDA-8 is my lowest priced amp, but I always grab it when I’m traveling. It’s a great little amp.

I thought about this a bit more and decided to ask you about your budget. The Electras are pretty decent speakers worthy of better amplification and/or better DAC. The IDA-16 might be worth trying even though it’s not warm sounding. Another idea is a DAC-9 paired to an ST-10 amp.
Michael
Title: Re: IDA-8 ($995) features and spec
Post by: huhpaul on 7 May 2018, 01:26 am
Thanks mresseguie!

Focal Electra 1008be is the model.
My budget is around $1200. looking for the DAC with it too, also compactness is important, which led me to the IDA-8.
The IDA-16 is out of my budget at this time.
Title: Re: IDA-8 ($995) features and spec
Post by: mresseguie on 7 May 2018, 01:44 am
I had guessed it might be budget constraints. I think it’s possible to stay darned near your $1200 budget by buying used DAC-9 and used ST-10 (or even demo pieces).  The DAC-9 I bought was a demo unit.

There’s a website called Hifi Shark (www.hifishark.com) that can save your searches and send you email notification every week. It scours dozens of audio sites’ classifieds for the product you’re seeking. I just checked - there are no used pieces in the US at this time.

A DAC-9 plus ST-10 will give you considerably more satisfaction than an IDA-8 in my opinion. And, yes, I also own an ST-10.

I don’t know where you’re located, but all my Nuprime purchases have been made through John Casler. He’s great to work with.

Regards,

Michael

Another option is to buy a HD-AVA which is being sold at a throwaway price at nuoem.com and it is less than 1200 right now - it has the guts of DAC10 and the IDA-16.

+1 to John Casler. I bought my HD-AVA from him - open box - and he gave me a great price for it. Enjoying it everyday via daphile+NUC (USB), chrome cast (optical) and oppo 203 (analog out)

I'm in Daegu, South Korea and I can find the IDA-8, STA-9 here for sure. I think the DAC is possible to get here too. I'm almost certain the other suggestions would have to be imported, so would bump up prices with import charges and shipping.

I have just try ida-8 at home. Within two days of run-in, I found it has remarkable bass. But , story ends there.

What speakers are you using? What other associated equipment?

Still, you may believe or not that DACs and Amps require sobre break in.  Most people tend to agree that they do (I'm still on the fence).  Whether it is real or it is you getting used to it, is a subject of great controversy.  Still, it may be worth giving it a longer run of evaluation?

Hope your situation improves, best regards,

Rafapolit's question is a good one.

In addition, what sized room are you in?

What music are you listening to?

How loudly are you listening?

Two days of burn in is a very short time. I have learned to wait at least 200 hours before I think about telling people my impressions or asking opinions.

I just picked up a used IDA-8 just by reading reviews on the nets and reading all 20 something pages here in this forum.  The reason for picking the IDA-8 is largely based the compact size and I am also very intrigued by class D amps.  I am downsizing from floor standing speakers (Neat Elite SX pairing with the Naim XS-2 int-amp which works brilliantly for me).  Source remain the same using Oppo BDP-105d and CAS using Mac mini.  I was originally put off by the fact the analog input for the IDA-8 will do the A-D-A conversion but I have decided to rip all my SACDs to DSF files so I won't have to deal with that option.  The Oppo will now primary used for video and for ripping SACDs only. Wish newer Nuprime amp will take HDMI input to accept DSD native but i guess the chance is small as most people nowaday will play DSF files only.  I am still learning how to use Audivana plus but I am currently upsampling everything to DSD128 as a start. Would love to hear other advices or pointer to  forums/sites for the settings recommendation.  It's strange I am going backward with DAC chip starting with my DAP using ES9028Pro and Sabre 9018 on the Oppo now to the even older version on the IDA-8 (9010 K2M!) but I can't have the cake and eat it I guess.  My current speakers are a pair of Neat IOTA which sensitivities are only 84db running 6ohms. These are probably the smallest speakers that sound decent not using a stand (even LS50 are too big for me, TAD 2201 even bigger or the S-A4SPT-PM which I can't find a place for demo). I just hook up the systems about 1 hour ago and comparing the Neat IOTA pairing with the Naim xs-2 they do sound very different. I can't tell which one I like more but now that I have sold the Naim I am not going to think too much about it and just enjoy the IDA-8.

Hello, shektau6.

I'm curious to learn your experience/impressions of the IDA-8 powering those speakers. What size room will you use? Near-field?

I used my IDA-8 to power my Fritz LS/5-R (83.5dB, 4 Ohm) two-ways for a couple(?) years before upgrading to the Nuprime ST-10. The IDA-8 was not quite powerful enough to get my speakers to sing in my living room. However, it was fine in my tiny home office.

I still own my IDA-8 because it's a great little amp. I take it traveling; use it in my office; connect it to my TV, and use it for outdoor parties in my backyard. Oh, and I've loaned it to friends while I was traveling overseas. At least one friend now owns one himself.

Attention Jason:

The IDA-8 rocks! :thumb:

Hi Michael, it's not nearfield but in a studio like apartment, the listening area is about 120-150 sq ft. The sound from these tiny speakers are no match for my previous floor standing ones but I don't have much choice as space is a premium from where I live.  I have not cranked up the volume yet to test the amp and will try this weekend!

Hi everyone,
I am new to the music world. I have just bought an IDA8 from a dealer in  Hongkong but have not set it up yet. At the moment  I have my HT setup with Onkyo RZ900 7.2 channels with 5.1 Polk Ti series speakers setup. All my music is in the PC next to the AVR. Music files are  FLAC and and few DSD files, varies from 64 to 256. I have a few questions in regarding to the setup and upgrade.
1) Should I connect IDA8 to preamp output from RZ900 using the analog in from HT and 2 front speakers hook to analog out from the IDA8 so that i can use the speakers for HT.
2) Should I connect the IDA8 to PC using the usb-3 or usb 2 from the PC (running window 10 with Jriver and Foobar 2000)
3) Should I connect the sub to the sub out of IDA8?
3) I listen to music 90% and watch 10% movies. I listen to female vocals jazz, flamenco guitars, acoustic guitar  and classical music. I intend to upgrade my collection to DSD 256 max as i can now buying them online. What is the good main pair of floor standing speakers should buy so that i can enjoy my type of music. My budget is under $3000 USD
Thanks everyone for your time and recommendation.

Try not to fall down the rabbit hole of power cords at this stage of the game. Pick a short but thick gauge that still has enough flexibility to go where you need it to without placing strain on the connectors. Don't bother with fancy shielding or whatnot unless you have a very large amount of signal cables resting on top, but even then simply spacing them carefully should be good enough.

Shorter power cables aren't necessarily better. In fact I've found the opposite. It depends on the cable design / gauge / shielding...and one's system.

I do not have such a cable to test and that's why I'm asking here, I think that those who have this amplifier have tested another wire

I've tried several different PCs with my IDA-8. I never heard a difference, so I do just as Jason recommends - I use the stock power cord.

Hello, new to this nice amp. I have a question. When I turn it off (with the remote or by pressing the input knob) it goes into standby, but the display lead is a blue dot, and the manual says it should be red. Is this normal? The only input connected to the amp is usb.

aaaaand last question (sorry I didn't come up with all these questions in the first post). When I turn on my IDA (connected to USB to pc) it produces a pop in my speakers when the display turns on and the volume escalates to its last setting. Is this normal?


I also have a technical question. Since I'm using low sensitivity speakers (Dynaudio Emit M10, sensitivity: 86), I read that they need to get quite some power to deliver their potential. If I listen to music at low-moderate levels, does it make any sense to set the IDA to say, 75/100, and lower the volume on windows/spotify/foobar/etc? Or is that the same as setting the IDA to 25/100 and raising the volume in those apps?

Can the IDA-8 unfold MQA files?
Title: Re: IDA-8 ($995) features and spec
Post by: rustydoglim on 1 Apr 2019, 06:56 pm
No. I don't think there is any difference whether you decode ("unfold") the MQA on your computer or in the USB chip.
I think many people don't realise that the DAC doesn't do any decoding of MQA format.
It is the firmware inside the USB communication chip (XMOS) that does the decoding before feeding the DAC.
We "figure" this out when we implemented MQA decoding in Evolution DAC.

Ahh. I see...and thanks. So just so I’m understanding you clearly, if I’m streaming a Tidal MQA file from a desktop app on my laptop/tablet and sending that content to the IDA-8 via USB all the decoding/unfolding is done at the laptop/tablet PROVIDED it’s capable of doing that?
Title: Re: IDA-8 ($995) features and spec
Post by: rustydoglim on 3 Apr 2019, 03:30 pm
Correct. If Tidal offer MQA on its desktop app, it has to be able to decode. Similarly all the smartphone apps can do the decode.
Without being able to decode MQA, there is no MQA streaming.

Hi,

I’m contemplating if I should buy the IDA 6 or 8. I understand that the 8 is more powerful but how’s the difference in sound quality, etc?
The 6 seems to have more features like two optical in and 4 pairs of banana plugs. Why?
The idea is to drive a pair of totem dreamcatcher speakers. Any thoughts and recommendations?

IDA-8 is a better integrated (better DAC/preamp) with more power.  The amp is warmer for IDA-8 and more powerful than the one in IDA-6.  For the same power, IDA-6's amp is not necessary worst than ID-8, just different, more neutral.

But since we are talking about integrated, so the sum of all parts of IDA-8 make it much better than IDA-6.

Also, Totems like a bit more juice (even the newer 8 Ohm speakers!), so I'd go with the 8.

For what it's worth, some folks here have not warmed up to the IDA-6 sound.  I think it's more oriented to restaurants and other type of places where music is more intended as a background rather than the main focus point.

Go with the 8!  But I know about your frustration about the two optical inputs. I complained about this and ended up buying the DAC-10 + ST-10 (4x the cost of the ida 8!) just to get the extra inputs.

Do you guys leave your IDa-8 running 24/7 (even when you are not using it or not gonna use it for some hours/days)? I read that class D amps should be left running, but I'm uncertain if this applies to the IDA-8 being it Class A+D.

I find my IDA-8 to not need much warm up time to get into its sweet zone...20-30 mins, maybe....so I turn it off when not in use. My Threshold (A/B) and First Watt F5 clone (A) are a totally different story and are best  left on.

I take this opportunity for a question: why is the analogue input of the IDA 8 digitized? What would the benefits be? I'm very satisfied with this amp, but having a turntable too, the idea that the analogue input is digitized annoys me a bit, although I must admit that in the end the sound is still good.

Title: Re: IDA-8 ($995) features and spec
Post by: RafaPolit on 20 May 2019, 05:54 pm
There are no "benefits".  It's a design issue: it's easier to have a single output flow, which, since you have a DAC in the IDA-8, is required to go through digital.  So the analog inputs are passed through the same process to simplify the device and keep costs low.

On the more expensive DAC-9 and DAC-10, this is not the case, and analog audio is kept analog. This is better, but more expensive.

Makes sense?
Best,
Rafa.

But do you think the Nuforce IA7 V3 or IDA 8 is better?

Title: Re: IDA-8 ($995) features and spec
Post by: RafaPolit on 22 May 2019, 06:20 pm
I have not followed NuForce after they split in two companies, leaving NuPrime with the "high end" products.

Still, there is still some overlap.  In this case, I have not heard the IA7.  But here are basic questions first: the NuForce hasn't a DAC, it's only an analog-source amp.  Are you 100% sure you won't need the DAC?

For the price of the NuForce, you can find interesting alternatives.

You have stumbled upon an interesting approach from NuPrime that presents its own complications: NuPrime has Power Amplifiers on one hand and DACs + PRE amplifiers on the other hand.

This leaves the "key" amplification alone, but leaves you without volume control.  PREs and DACs are combined.  Other houses (Moon by Simaudio comes to mind) offer standalone DACs and have a large portion of their product line in Integrated Amplifiers, which mix the PRE + AMP in the same device.  This allows for the "sources" to be more independent.

In your case, and for the money of the NuForce, you could buy a STA-9 which is probably a much better amp, but then... what to do for volume control?  Still, with what's left from the $1400 or more from the NuForce (vs the $700 of the STA-9) you could buy a phono preamp.

What are your other sources that you are considering the NuForce?

Post by: jonbee on 22 May 2019, 08:14 pm
I received my IDA-8 this week. It is a very neutral, detailed and open sounding amp, much like the rest of the Nuprime line. Not as much depth as the Dac-10/ST10 however. The main difference I hear is that it sounds a bit dynamically polite with not as much slam compared to the bigger offerings. That extra slam will cost $$, if you want to keep the other wonderful qualities and features this model has.
Accordingly I'm not sure it is a good choice for hard to drive speakers played loudly in bigger rooms, but it is a very good value for its sweet, clear sound where brute force is not required.
I'm using it in a 12x16 room with a pair of very high rez 87 dbw $$$ speakers, and it is wonderful.
Very nice operating features for the $, too.

By "stand-by" you mean back switch turned on and powered off by the remote, right? I tried leaving it on (meaning, turned on and running) and I noticed it got very hot, like toasty hot after a couple of days. The thing is, I use my IDA-8 as my sound interface in Windows, in order to use my passive speakers. So it is kind of a bummer having to switch it on and off every time I want to, say, just watch a random youtube video (instead of listening to music, which is its main use for me)

What do you think, RafaPolit?
Title: Re: IDA-8 ($995) features and spec
Post by: RafaPolit on 25 May 2019, 05:16 pm
Well, I'm nothing but an enthusiast, so take my answer as simply my point of view  :)

I agree that your scenario is the one area which is not comfortable with passives and amps and etc.  My solution was to add desktop computer speakers (Logitech 5.1 system) that stays on all the time connected to the computer's audio 5.1 output, and configured as the default sound output device.

Then, when I want critical listening, I switch the output (either via control panel, or, more commonly, by the app performing the playing, like Audirvana, or Roon, etc.) to the DAC that is connected to the 'good' system.

Still, there is some overhead involved in this procedure, but takes away the need to turn on everything just to watch bloopers on YouTube or the news.

A really nice alternative, would be very good active wireless speakers, like the KEF LSx (or whatever the new small ones are called) which will solve all your needs and still leave you with great sound all around.

Where I live, power is not all that reliable, I only leave DACs on at all times, all my other equipment is turned off / on as required.  Even the DAC-10 is always on standby and not on all the time.

That's me, I'm sure others have other approaches.

Hope this helps,
Rafa.

Yeah, I was considering getting cheap speakers and use my PCs onboard card as output, but I don't have any (if only my dad hadn't put those old Edifiers who knows where, haha). I'm actually using my screens audio speaker for YT videos, but well, it sounds worse than corded phone. At least it's better than nothing.

It is a real sweet piece of gear for the price- build (and size!), sonics, and features. I love mine, beautifully powering my Eggleston speakers in a smallish room. I know of none that can offer as much for the $.
Wiring up I/Os is a significant part of cost of production, so lower cost items have fewer. It is also a way to encourage us to move up to more $ options.
Title: Re: IDA-8 ($995) features and spec
Post by: RafaPolit on 26 May 2019, 04:43 pm
Here, I had a similar process and actually decided on the 10s exactly because I wanted more inputs: TV, airport express, etc. It meant spending 3 times as much as the IDA (there are a lot of threads about me asking all sorts of questions).

The truth is that now I have the TV via optical, and a RPi via USB and this is all I need.

In the living room, it's even simpler: a single RPi via Coaxial (Allo DigiOne) is all the inputs we will ever need.

I know this won't be everyone's case, but I encourage you to think about costs elsewhere: instead of spending more for more inputs, perhaps a Roon license is enough to send everything to a device like he RPi and you have a hell of an streamer.  Or a chromecast in the TV (or AppleTV or Fire, or whatever is to your taste) will allow for a single TV to be the central hub of a setup. (With the TV on at all times, of course).

So, after voicing protests against the number of inputs myself, I now think differently and think these are more than enough.

Congrats on your purchase! Enjoy.
Rafa.

Rafe - agree that it always possible to find work arounds. Especially if one can use the Coaxial input but I get the feeling that Coaxial is becoming less common. However the Allo is one opinion. I need the optic in for my tv.

Hello, Pf.

I hope you don’t mind my popping in to answer your question. Leaving it on in standby mode is just fine. I bought one of the first IDA-8s when they first hit the market, and I either keep mine in standby or simply leave it in ‘full’ on mode. I’ve never had an issue with mine. It’s a great little amp.

Read this FAQ: https://nuprimeaudio.com/ufaqs/what-kind-of-volume-control-and-preamp-do-you-use-for-your-dac/ (https://nuprimeaudio.com/ufaqs/what-kind-of-volume-control-and-preamp-do-you-use-for-your-dac/)

This is how the signals travel through the blocks inside:  digital switch --> DAC --> [optional analog preamp] --> power amp
DAC chips have advanced to the point where even the "entry level" version has very accurate digital volume control (32bit).  So the simplest implementation for volume control is all digital and then just feed the DAC output to power amp.  The result can be amazing.

When analog gets in the middle, that's where things become expensive and cumbersome. Add a remote control to the complexity - now you have to control the digital volume inside the DAC, and also the analog preamp. The FAQ explained how it is done.
For an entry level integrated, if we choose to add the analog preamp, it will improve the analog input, BUT DEGRATE the all the digital inputs. That resulted in overall worst performance.  If you want to have ultimate performance for analog and digital inputs, then you have to upgrade to DAC-9 or DAC-10.

For IDA-8, the analog input is converted to digital with a small loss of fidelity, so that analog preamp is not required.

Sometimes you see the term "preamp stage" in the context of power amp module, this preamp stage is not the same preamp as in the device. The preamp stage in a Class D power amp design serves to adjust the gain and sonic characteristic.

 Hello all,
I would appreciate help with IDA6 problem.
Recently upon startup when output relay should be energized it is clicking on/off instead and music can't be played. There is the same behavior regardless of the input channel selected and only if I disconnect speaker connector it stops clicking. In the very beginning when issue appears it was OK after few clicks and continue playing selected input. Is this device defected or there is a chance to make it work properly again. I really like this great Nuprime product and would like to listen it again. I do not have any receipt or warranty because I bought it on Ebay few months ago.
I would appreciate any help or guidance with this issue.

Thank you very much !!

Looks like your IDA-6 has some problem, you should contact support and create a help desk ticket (follow instruction from the website).
Title: Re: IDA-8 ($995) features and spec
Post by: John Casler on 9 Jun 2019, 08:42 pm
Franco,

One other thing to try:

The amp protection circuit might be seeing a "short" and not be able to complete the circuit.

If it is a short, it could be in the speaker cable, or the actual speaker itself has somehow shorted.

To test simply unplug each speaker cable and examine it for possible shorts.

Then while the amp is ON and music is playing connect each speaker separately and see if either play through the amp.

If music play through one, and not the other, then swap the speaker cable that does work.

This will help in determining if it is something else besides the amp, before you file the support ticket and send it in.

Good luck.

DAC is an acronym for Digital to Analog Converter.
Without a way for humans to listen to digital code, the code has to be converted to analog signals for us to hear it. That's what a DAC does.

Post by: onurb on 11 Jun 2019, 09:16 pm
I know this, but I assumed that in the case of IDA 8 the dac was only used for volume control and the signal was amplified in the digital domain, as for example in the Nuforce DDA 120, if I'm not mistaken.

Bruno
Title: Re: IDA-8 ($995) features and spec
Post by: rustydoglim on 12 Jun 2019, 09:00 am
All the digital inputs go through a digital switch and then into DAC chip.  The DAC chip does volume control as well as converting it to analog.
The output of the DAC chip goes from 0 to 2V max, and then to the internal power amp.
So when you turn the volume knob on IDA-8 you are changing the volume inside the DAC.

But for higher end DAC such as DAC-10, the volume control affects TWO places: the DAC as well as the resistor ladder preamp after the DAC.
If the input is digital, then the preamp doesn't change the volume (it just switch it through a 0 db gain), the volume is best controlled inside the DAC.
But if the input is analog (remember, in this case there is no A2D conversion for DAC-10), then volume gets changed by the preamp after the DAC.
It is kind of complicated for non tech people, there is an FAQ under the DAC section about this, I am not sure if that helps.
All this trouble just for one analog input  :duh:   I know for some people that one input is the most important.

I've had TDSS mod 3 of my Nuprime pieces (2 DAC10H, ST-10) with their full mods (level 3?) and the difference is obvious and well worth the pretty modest $ for a high end system.
I don't know how close the level 1 DRRT mod they mention is to the full mods I have, which are more $ (about twice, I think), but the TDSS mods are not snake oil, imo. The DRRT is priced at ~$325. Included in the retail price, I think that is a nice upgrade. Maybe the cost of a full upgrade is reduced?
Maybe I'll have my IDA-8 modded. The sound and features are amazing at the price already.

Small pop sound is normal in most cases. Think about how loud your speaker can sound and observe the woofer's movement when you play loud music, especially drum.  It is probably 10 times louder than the pop sound.

could someone teach me what the sub-out are for? I know they are, logically, for a subwoofer, that I don't own, but can these be used as line-out to connect them to another amp?

Generally, if there are L + R stereo sub outputs, they are line outputs that could be used as preamp outputs (as opposed to mono sub outputs) if they are full-range without any low-pass filtering.

In the case of the IDA-8, these full-range outputs originally had 3X gain (6V) as opposed to more-or-less standard 2V, and therefore were described as subwoofer outputs and not preamp outputs.

However, as of August 14, 2015 all IDA-8 shipped had sub outputs with a default of  1X gain (2V), with 2X and 3X gain available on special order.

It is of little consequence, since your sub has a gain control to get the right balance.

So the  different voltage output will only affect "fixed" volume subs.

No, it was never meant to come with 2 remotes :)
LONG time ago, when we first introduce IDA-8, the original remote was not good enough.  So we made a new remote in later production. But since we have spare remotes, we just include them while supplies last.  The 1st remote stocks have long gone.

Are there particular models of speakers that you (or anyone) has found to make a noteworthy pairing with the IDA-8?

I’ve owned an IDA-8 since they first hit the market, and I still like and use mine. I’ve used it to power a pretty wide range of speakers in this time. Remember: It’s only 100w/ch, so it won’t do well trying to power low sensitivity speakers or speakers in a huge room.

Okay, I’ll provide two groups - one for speakers that didn’t seem to pair well, and one for speakers that seemed to pair well. [I’m using my phone to type, so I may make changes once I get home.]

Inferior pairing:

Fritz Loudspeakers LS/5-R (83.5dB), Daedalus Audio Apollos (96.5dB), PranaFidelity floor standing speakers 'Vayu', Lawrence Audio Cellos
I'm back on my laptop, so here's a little more info: The LS/5-R monitors are hungry little guys that really need more power to 'sing'. The IDA-8's 100w doesn't do them justice. My Apollos are very efficient, but they sound thin when powered by the IDA-8. I don't recall the Cellos' efficiency, but they, too, sounded thin. The Vayu sounded a bit thin, too.

My take away is that the above big speakers just sound better with more robust amps.

Good pairing:

ProAc Response D2, Adelphos two-way monitors using SB Acoustics Satori drivers designed by Jeff Bagby (87dB), Daedalus Audio Pans (94? dB), PranaFidelity Fifty/90monitors, Dynaco A-25 speakers, Paradigm Studio 20 v.3, Wild Burro 8” full range drivers on Betsy OB baffles, and CSS Audio Criton 1TD.....(pretty sure there were a couple more, but I don't recall right now).

It seems as though mid-efficient two-way monitors just seem to pair well with the IDA-8. It's got an almost tube-like sound with these speakers. I've got the IDA-8 powering my Adelphos monitors in our BIG family room. This room sucks bass out, but midrange and above frequencies sound great. I've got my TV and a Mac connected as well.

What amp would you consider as an upgrade to the IDA-8? I have a pair of KEF R300 and I was looking at Cambridge Audio CXA80 and Marantz PM8005, but I couldn't find comparisons to the Nuprime.

Correct me if I'm wrong, but the Marantz lacks a DAC, no? The IDA-8 and CXA80 both have DACs. Do you want an all-in-one, or amp/preamp with separate DAC?

I haven't heard the CXA80, but the included DAC is purported to be the same as the DAC Magic 100's. My first DAC was the DAC MagicPlus (a step up from the 100), and it was not a revealing DAC. It really held my system back. The IDA-8's DAC is actually pretty decent.

I'm biased here. Of the three amps you mentioned, I'd stick with the IDA-8. However, if you want an upgrade from this (and want an all-in-one unit), then take a look at the IDA-16. I know there are other  all-in-one amplifiers out there, but Nuprime is my 'go to first' for all-in-one amps. I just bought a new IDA-16 that was delivered just today because I gave my son my IDA-8. [It's his first system, and he's delighted.]  Unfortunately for me, my new IDA-16 is in Oregon while I am over-wintering in Asia. I'll tell you how I like it in March.  :(

While the IDA 16 looks fantastic, I doubt I could find it in my country (Argentina) and if I did, it would probably be at a super crazy price.

I was actually considering getting a Pro Ject DS2 digital in the future for that MQA support (snake oil?), but I'm currently able to get the CXA80, pm8005, and pm7004 for relatively cheap and used (it's hard to find cheap used audio stuff here).

Today I tried the pm7004 and really liked it's sound compared to the IDA-8 (which sounded less detailed in mids and too bassy) and an Arcam FM28, but with KEF LS50 (similar, but not exactly like my R300). But then again, I lose a fantastic DAC until I'm able to get that Pro ject DAC.

You have made me laugh!

I have been claiming these conditions we 'south americans' have to deal with.  It's far from ideal: "which would you choose between A or B?"... "very simple! Take both, pick the one you like, return the other!".

I spend more time explaining my regional constraints rather than actually getting info, but the truth is we are bound to trust reviewers and user stories, and blindly (deafly?) making a purchase with the best informed decision.

Not really assuring.

For me, locally NuPrime is no longer available, apparently distribution channels forced the local reseller to have to first ship and import into the US and then back here to Ecuador, where the cost of $700 STA-9 ended up being close to $2000, so no longer the correct price vs performance niche... not to mention the fact that we earn about a quarter of what a US citizen makes.  So even $700 would be four times as expensive for us... but then it costs almost 3x the cost, so now it's 12 times harder for us to access to such products.

It's simply absurd and considerably maddening.

Wish you the best of lucks with your adventure, but the truth is that you are probably better sourcing from whatever is available locally, as limiting as that is.

Argentina has more problem than other South America country.  The item can't even get in. 
For Ecuador, at least you could buy direct from us. If you want to audition a new amp for example, and is already a customer, you can order and return the amp for a full refund (the usual conditions applies, ie return in a very good shape, box damage ok, but don't scratch the amp). Or order 2 different amps and return one.

Argentina has this black market of hi-fi audio that would really surprise you. I mean, we can buy very expensive stuff from these "importers" (who I believe are customs employees), so there's quite a lot to choose from. Most of them are even nice enough to let you got and listen to different equipment (as people normally do in the US/Europe). Unfortunately, none seem to import Nuprime products for whatever reason.

I'm leaning towards Vincent upon one of these fellow's recommendation, but I've yet to go and listen to that brand's amplifiers and compared them to the IDA-8

We don't know who they are, and no one from there contacted us.  Well, one reason we always hear about from dealers who sell very expensive stuff is that they don't want to sell NuPrime.

From a dealer where I used to reside, I was told he wouldn't carry stuff that would take up floor space which could be used to display items they could make more money on.  So they don't necessarily look out for a customer's wallet.

Jason,

I spent yesterday afternoon at the 圓山大飯店 roaming the different room at the Taipei Audio & Art Show. There were two rooms with Nuprime gear, and each one had an IDA-8 in the rack (in addition to other components). One room also had a pair of STA-9 amps (in use). I think I snapped a pick. I'll post a pic once I upload them all to my computer.

Hi,
I own IDA-8, KEF LS50, REL T/7i
What should I do to upgrade my system/sound ?
Will IDA-16 be significantly better than IDA-8 or should I go for ST-10+DAC-10 ?
I'm also considering Hegel H190

Hello, JAC_ZAR,

The IDA-8 and IDA-16 have a very different sound. The IDA-8 (with the right speakers) can sound almost tube-like. It is - in my opinion - a great product offered at a steal of a price. I owned one of the first units until about 6 months ago because I gave it to my son as a house warming gift. I replaced it with an IDA-16 because I wanted more power. The IDA-16 is clearer sounding and definitely more analytical. I went through a phase a few years ago during which I thought I liked analytical, but after about 18 months realized I do not. I really like the tube-like sound - regardless of whether it's from a SS amp or a tube amp.

Once I had burned the IDA-16 in and listened to many different songs and three different pairs of speakers, I discovered that what I really wanted was an IDA-8 with a 200 watt amplifier. Apparently, that is not possible.  :( 

There are plenty of people who own an IDA-16 and love what it does and how it sounds in their systems, so don't take my criticisms as representative of the market. I have owned an ST-10. I prefer its sound to that of the IDA-16. I haven't heard the DAC-10 in so many years that I can't possibly tell you how it sounds.

Enjoy your audio journey.

Michael

The DAC-10 is a great piece and pretty much neutral unlike many Sabre based DAC's. To get a half sized combo that gets a sound similar to the IDA-8 with power that my be possible with the ST-10 and the new Alita DAC. The combo side by side would be less than an inch wider than the IDA-16.

If you don't need digital inputs, then you might consider the new AMG PRA.  It is spectacular

Mated with the AMG STA amp (or a pair in mono) should offer some of the IDA-8 sonic qualities except much better.

Check with your dealer and if you go with that pairing there my be room to trade the IDA-8 in.

If you do need digital inputs, just mix the DAC-10 and the AMG STA or 2.

Let me know if you have questions.

For a few $ the TDSS mods significantly improve the clarity of the IDA-8 and DAC-10. It does not increase the power, however. I have modded Nuprimes (IDA-8 and 2 DAC10-h) in my 3 systems and to me they are permanent fixtures. After 53 years of swapping around that is saying something. Unbeatable values and features in their niches, with or without mods.

IDA-8 has achieved the perfect balance for an entry level audiophile integrated at unbeatable price for the sound quality.
To be honest, we don't know how to make it sound better or more powerful without increasing the price by more than 50%.
It is kind of like the Dad's personal music system whereas Omnia A300 is for the whole family.
Cultural and geographical preferences are also quite different. So we do have some people that prefer the A300 sound over IDA-8.

What the IDA-8 lacks is a very good but low cost streaming transport (Stream 9 Mini).
But we have to release the incredible Stream 9 transport first.  :thumb:
If budget allows, go for the Stream 9 (less than $1K, exact price available end of Feb), you will not regret it.  For the same music, ie same 16-bit/44.1kHz music from CDT-10 versus same file streamed from network NAS, the performance of Stream 9 rival that of CDT-10.

Discovering my new IDA-8  :D, I am also facing new questions as I go...  :?
Unless I have missed it in the manual and scanning through this very extensive thread, I didn't find the answers to the following ones:

-> What is the maximum section of speaker cables (diameter [mm] of area [mm²]) that can be used 'bare wire' (through the hole in the IDA8's terminals)?
I had borrowed some speaker cables (Van den Hul CS122, with a cross-section area of 2.96 mm² according to its specs) to test my new setup, but it seems the cable is too wide/thick to fit well 'bare wire' into the speaker terminals (through the holes transversal to the terminals). (I know I could use banana-plugs (or spades), but I would prefer not to, as I don't need to switch cables regularly, would prefer a solid connection, and this would save me some costs and also space in case of banana-plugs etc.)

-> Can the 'extension port', which is of physical USB-format, be used to power my Chromecast audio (which sends its signal back to the IDA-8 via the optical input)?
(That would save me space and power-socket space.) I don't know if there is any risk in doing so, e.g. if one would inadvertently select that extension port as input while the Chromecast is connected to it. I know Nuprime has other, more feature-rich streamers too, but for the moment I'm quite happy with the limited Chromecast functionality and already own one.

Yes, but check the pins compatibility on the Chromecast audio power supply (they should be, but you better check).

I'd agree with that. I can't think of a real competitor at this price where massive drive power is not required. I use mine to drive my inefficient but hi-rez class A Revel Gems in a 10x12 room and it is vey satisfying.
Ultimately it has less slam and fine detail resolution than my far more expensive Cherry Maraschinos or my IDA-16, but it is always musically satisfying in the right system environment.
The IDA-16 is a good choice for a move up in power, slam and resolution. It works great with my Avalons, which are a tough load. Not the best I've used, but diminishing returns come in steeply above this level.

Thanks!  :D
I cannot find the details about the Chromecast Audio pins (which is used or not and for what).  :(
However, as the Chromecast works with any USB-power outlets, I assume it follows USB-protocol at least for charging (power pins +&- correct), and I understand from your answer that the Nuprime extension ports also does. My concern (not being familiar with those protocols), is if there is any risk of using them together that way if the pins are correct (data versus power): could there still be a risk due to some signal exchanges via the data-pins, for any of the equipments (creating a bug or any other thing)?
I guess that what should without without any risk is looking for a USB-cable that only has the two power-pins connected (charging-only cable).
Could I be forgetting anything here?
Maybe the maximum power that can be drawn from the Nuprime extension port? Are there some specs available for that, does it follow some standard or include a safety which, in case the attached item tries to draw more current, would just limit the current output safeguarding all internals of the Nuprime's?

I agree.
The AMG-PRA (preamp) & AMG-STA (power amp, 130w) delivers an amazingly good sound, under a compact size.
The Absolute Sound "highly recommended" (review (https://www.theabsolutesound.com/articles/nuprime-amg-sta-power-amplifier-and-amg-pra-preamplifier))
Hifi-advice "highly recommended" (review (https://www.hifi-advice.com/blog/amplifier-reviews/power-amplifier-reviews/nuprime-amg-pra-with-2x-sta-stereo-power-amplifier/))

That combo drives at my place, in a very good and silent room, one of the finest-sounding 2-ways speakers I know: the Harbeth M30.2 Anniversary. I listen to classical music, wich is very, very demanding regarding timbres. I attended countless of live, unamplified performances.
The result that the AMG combo delivers is very good (and I am very demanding).

Just one pic (for the sake of teasing ;-)

First of all, thanks for Nuprime for making this lovely little amp, it is so good for this price that many users has reviewed so I don't need to repeat. As a new user, I have 2 small questions.

1: I can only set 24 or 32 bit in PC (Win 10), no 16 bit as mentioned in manual, does anyone face the same problem?
2: Can any user share which digital input sound the best? I don't have any hi-res file so the better spec in USB input is not relevant to me.

Thanks for your helping.

Since you are using PC with USB audio, you should be able to set input in higher bit rate but that will depend on your music file.
If your files are all 16-bit, then IDA-8 will only decode them as 16-bit.
You should be using USB audio if you are connecting the PC to IDA-8, even if your PC has optical or coaxial outputs.

The remote control on my IDA-8 has quit working.  Does anyone know how I can get a replacement?  I was able to speak to the guy who distributes Nuprime products and he asked me to email him and he'd get back to me but he never did.  I'd be open to buying a used remote or even a universal remote if those options are available.  Thanks!

I would suggest you fill out a "support ticket" and ask the procedure to get a new remote, or the remote codes so you can program an after market unit.

The remote key codes are published on the product page: https://nuprimeaudio.com/product/ida-8/

 Thanks for that info!

I've spoken with John Casler, who couldn't have been more helpful.  He guided me to complete a service request directly with NuPrime and so hopefully I'll have a working remote soon.  Thanks again to everyone for their help!

I would like to ask if I want to connect IDA8 to a headphone amp, I just use a pair of RCA to line out, set max volume, and let the headphone amp for volume control? But do I need to unplug the speaker binding post firstly? Thanks.

IDA-8 wasn't designed to turn off the speaker output if the line out is connected to the headphone amp.
Unfortunately, you have to unplug the speaker cables.

I don't want to hijack the thread, but I wanted to chime in about the IDA-8 that I've had running since right when it came out - via USB from the computer then off to the Axiom Audio M3's in my desktop set-up.

This is such a beautiful sounding (and off-the charts value) amp that I will do whatever it takes to keep her in the system.  It is great to also know that the service, if ever needed, is first-rate!
