Title: NuPrime Amp Comparison
Post by: rustydoglim on 11 Nov 2015, 12:40 pm
This topic is for comparison of various NuPrime Amps.  If you want to post a short review, please focus on the differences. Review of specific model should be in the respective topic, not here.
Questions and comments are welcome.  We try to be as objective as possible, taking into consideration what we have done in the design so this is not purely "ranking by ear".  When we set out to design a new model, we have a good idea of where we want to position the product and its target customers. And after ten years of designing high-end audio, our team pretty much can precisely control every aspect of the performance and sound characteristic. I am confident to say that there isn't any amp company today that can match our capability in delivering such precise control of the sound.

Hi Jason,

Thank you for doing this.  So looking at that chart, does that mean the power amp section of the IDA-8 would be considered slightly better than the STA-9 for dynamics, resolution, high frequency extension and texture?  Or am I not reading this right?

Thanks!
Title: Re: NuPrime Amp Comparison
Post by: rustydoglim on 11 Nov 2015, 01:08 pm
I have updated the table. The previous format wasn't clear.  If several amps are in the same cell, they are ranked the same.
For example, for Dynamic, Resolution, Texture, IDA-8 and STA-9 are the same.

STA-9 design is derived from the same amp as STA-8, we made it more tube-like.  But since they are fundamentally from the same design, dynamic and resolution would be the same. For texture, you can argue that STA-9 would be warmer with more even harmonics (seriously, we can control the even harmonics of an amp, scary huh), but the difference is not big enough to separate them.

I think while many high-end companies have stopped innovating, NuPrime is ushering a new era of high-end audio.
It is not that we have been over charging customers ten years ago, but it takes many years of R&D to truly understand how to manipulate high power amp and Class-D designs. With each discovery, we are able to improve the performance, gain more control, and find ways to reduce the cost.

Actually what you have seen here are R&D that have been underway for the past year.  We are already hard at work on our new Omnia server and wireless platform.  If you ever think of buying a NAS, a hi-res audio player, a media sever - wait for the Omnia product.  This is a ground breaking product.

That will be interesting.  I am definitely intrigued.

I have been looking squarely at the Auralic Aries Mini as a music server into whichever NuPrime product(s) I end up purchasing next, but I can hold off for the time being as I already have a dedicated PC for the task. The PC is fine, just too big and bulky with too many unnecessary features.  Which is why I am looking for smaller for a music server.  But I also want it to be headless and be able to control it remotely like I can with my PC.

PM me and I can tell you more about the Omnia server. It is expected to ship sometime late January if we are lucky.
I started an Omnia topic here and gave away some spec and features for the Omnia.  Or we can continue the Q&A on that Omnia topic.

Two people who have had all three in their system have told me that the ST-10 is between the IDA-16 and IDA-8 in terms of warmth.  They both described the 16 as "lean."

Post by: ChuckT on 13 Mar 2016, 06:53 am
I notice there is a product missing in the Nuprime line, and that is the integrated amp. I wanted to upgrade my IDA-8 but the next one up is the IDA-16, but I want a separate dac input to a pure integrated amp. Any plans for that hole to be filled?
Title: Re: NuPrime Amp Comparison
Post by: rustydoglim on 13 Mar 2016, 07:39 am
I guess you want more analog inputs. Because we put very good (switch resistor design) preamp and volume control into our DAC and integrated DAC.  There is just no demand anymore for integrated without a DAC. If we make one, you won't pay for it anyway because it will be too expensive. The price of a product goes up dramatically if it is only made for a few. This has nothing to do with the actual cost of material.
Title: Re: NuPrime Amp Comparison
Post by: ChuckT on 13 Mar 2016, 02:35 pm
I found that very odd since if you consider how many pure dac are made and sold every year, this will be the number of potential integrated amps + preamp & amp in buyers (assuming they ditch their old system).
Unless you assume that all who buys a pure dac will only buy a separate preamp and amp, but I can tell you this is not the case. I, for one, wants a good integrated amp. The IDA-8 is not good enough since I found the RCA input do not live up to the amps potential, any external dac I use for input will go thru the IDA8 ESS dac and I don't want that. To give you some ideas, I am planning to play with some multibit and R2R dacs.
Give me a ST10 or STA9 with a good preamp section and I will buy it immediately.
Title: Re: NuPrime Amp Comparison
Post by: rustydoglim on 13 Mar 2016, 03:58 pm
What would considered pure DAC? All DACs have preamp built in.
So if you have DAC-9 or DAC-10 with a stereo amp, why do you need a preamp?
We had integrated amp before with Nuforce models and the message we got from sales channels is that people want integrated with DAC.

HPA-9, DAC-9 and STA-9 together is an incredible set. throw in ST-10 and DAC-10 in the mix.

Title: Re: NuPrime Amp Comparison
Post by: audioguy213 on 14 Jun 2016, 04:31 pm
Does the ST-9 move on the chart when used a a monobloc?
I see the bridged power goes up, what about soundstage, resolution bass extension, etc.
Does a mono bloc ST-9 start to approach the ST-10 in that regard, or does the sonic tuning mean it is consistent on the chart, just with more headroom when used as a mono?
Title: Re: NuPrime Amp Comparison
Post by: rustydoglim on 14 Jun 2016, 04:44 pm
No it won't because even though STA-9 has unique bridging circuit (instead of using Op Amp), it doesn't change the design of the amp.
It becomes "sounds livelier and more dynamic" - which is due to the increase in power. 

Therefore we did not change the positions of STA-9 in the comparison chart and it shouldn't be.  Otherwise our chart is simply bull shit :).

Our French distributor prefers STA-9 + DAC-10 over all other combinations. And others love ST-10 and DAC-10. So as I keep saying, the differences between these characteristic are quite small. They are all very good.

Jason,

Which amp is most popular in Taiwan?

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

With so much confusion over you amplifiers, I've come up with a great idea. Send me all your amplifiers (and a couple DACs), and I'll host a small G2G! Then, I (and whomever attends) will post our impressions.  :thumb:
Title: Re: NuPrime Amp Comparison
Post by: rustydoglim on 14 Jun 2016, 07:37 pm
There is no confusion. Just follow the Amp Comparison guide.
People get confused because they want to get "the best".  So they go back and forth over one model versus another.
For customers who know what they like to hear, they can quickly pick what they need.

If you have a <=$1000 budget for integrated and want "the best", then IDA-8 has no competition on the market.
If you want the most powerful, flexible and warmth system, then go for DAC-9+STA-9 x 2, with HPA-9 for headphones enthusiasts. And this is the best value for money component set.
If you are looking for very smooth, detailed, dynamic, pretty much near perfect system that is neutral, then ST-10 and DAC-10H.  Or go with IDA-16 for lower price but just less that what ST-10 offers.
If you want something similar to ST-10 and DAC-10H, but toward warmer side, then STA-9 x 2 + DAC-10H.
If you have deep pocket and want the best stereo amp and willing to pay more than double the price for the extra edge (it cost exponentially more for the last 5 to 10% extra in all these areas), then Ref 20
I can go on and on but all the above selections are just based on the Amp Comparison.

If you have no idea what you want, then just make your decision on: 1) Your budget and 2) your music preference
From budget and music preference, you can also easily find the components that you need from the Amp Comparison chart.

Ya, I think we should publish another chart using Music preference and budget as a guide!

Jason tells it like it is, no B.S. or hyped-up marketing crap with ridiculous pricing, the sound really speaks for itself.

I still have and totally enjoy the Ref 9V2 SE's with a big-ass 6SN7 tube preamp, CEC transport and DHT Dac, heavenly.

Yes, very refreshing and straight forward.  Im going to really look at a int from this company. Very informative thread also. I could be up for a change in my main stereo. But it would be a big decision to sell a couple components, pre and power ,to cut cost of a integrated, but it might be worth it.

budget is not an issue,

well recorded rock (Steely Dan) and funk/jazz (New Mastersounds, Lettuce)
want: dynamics, bass slam, ease driving 89db 4 ohm speakers, smooth top end that errs on the side of forgiving rather than revealing of bad recordings

Ref20 are not in the running, but everything else you make is,

please advise.

MCH-K38 or STA-9 x 2.  If you are into classical I would recommend ST-10 or IDA-16.

I totally agree. I have the Ref 9V3 SE's and have had them for 10 or so yrs (Ref9 V2's upgraded). Jason personally corresponded with me on the upgrade. I was in the UK for 14 yrs and when moving back to the US I inquired about buying new US plug power cords for the amps and my P9 Nuforce/now Prime gear and Jason sent them to me in the UK free. Great, great customer service and an excellent product

Much depends on your system and listening preferences.

Early and Classic Rock was not always recorded well (although some like Stairway to Heaven remastered are incredible) so accuracy will show you the lumps and bumps.  Like always.

All and all, another consideration, might be the DAC-10 with a Pair of STA-9, which can ever so slightly smooth out edgy recordings a bit.

A bone to pick upon components picked because they play a certain type of music. I say its rediculos.  If a component cant really do all types of music,why would you want that. Music of all kinds is dynamic and ever changing. I guess i just dont get it.

I should have mentioned that I'm very much leaning toward Spatial M3 Turbo S speakers, so if anyone could make amp and dac recommendations for these speakers and my preference for 60s-90s rock, I'd certainly appreciate it.

I am running the DAC-10/ST-10 combo with the M3 Turbo S right now and the combination is excellent.  Type of music doesn't matter and short of rap and opera I have tried it all.

You are partly right if someone can design a Perfect Amp. And cost is no object.
Music is dynamic. No amp in the world can perform well at all frequencies and all power level, within reasonable cost.

Linear power supply is cheaper than switching power supply but it is slow and very bulky. Low noise and high performance switching power supply is difficult to design and costly. I haven't even touched the amps.  I am sure you get the point. We are dealing very physical world and it is difficult. 

We are in high-end audio territory and the sonic differences between these amps are relatively small, many casual listeners can't tell the differences.  Furthermore, different people reacts to the same music differently. That's why some people love tube sound. And that's why there are so many speakers out there.

It has been updated. Note that STA-6's position on the warmth and texture.
It shares the same design as STA-9, but tuned toward neutral with slightly more details.
It is very simple to choose between these two: if you listen to classical and jazz music, pick STA-6. If you have a mix of all types of music and want to maximise the effect of explosion in a movie, go with STA-9.

Hi Jason,

Aparently, the sta-6 position on the chart did not survive the migration to the new site.  The chart showing on the new comparison chart is, once more, lacking the STA-6.  Also, it would be nice to see the IDA-6 as well there?

I think Jason mentioned the the STA-6 is of a similar sound, to the STA-9.

That said, I have heard and used the STA-6 and found it exceptional for such an inexpensive amp.

Down side, is that it does not have XLR inputs if you require them.

Keep in mind bridged use of the NuPRIME Amps IMPROVE the sound and specs, opposite of conventional amps.

Hi everyone,

I would like to use HD-AVA as power amplifier of my Marantz 1608 which has front preouts, because of the interesting ADA price.
So I am not interested in the AV section, but in the Stereo part of it.

In the amp comparison page, the Stereo components of the AVA are not mentioned (for ex. Op Amp + Half Bridge + Switching) and no picture of the inside in the product page, but in the amp comparison chart it seems to have the similar sonic features of the IDA-16.

I have seen that "It is the same amp section as the IDA-16." in this thread.
But what about these features of the IDA-16, are these the same?: "the Switch-Mode Power Supply (SMPS) technology. For thundering, authoritative bass performance, the IDA-16’s innovative supply and its Cross-Matrix Array (CMA) capacitor bank"

On top of that why is the sound stage better and the texture worse?

Many thanks, I am about to buy one of the NuPrime amps, but figuring out which one...

Thanks

Title: Re: NuPrime Amp Comparison
Post by: rustydoglim on 13 Mar 2018, 03:24 pm
HD-AVA and IDA-16 has very similar amp sound characteristic because they use the same amp module.
But obviously the power supplies are different, but that has secondary effect on the sound.
They also shared mostly the same DAC. But keep in mind that DAC design is not like a wheel of a car where you just swap the parts.
So HD-AVA will get you close to IDA-16 if you are using USB input.
The AV part is not easy to use (read manual and online FAQ thoroughly and you will be fine) but very good sounding, especially you can use it to play movies and music from external hard disk.

Hi all,

I have just setup a DAC10H connected to NuForce Ref9v3SE monos.  The sound is incredibly detailed and amazing for Accoustic and blues but I'm finding it a little too accurate for Rock Music.  To get the sound I'm looking for for rock I'm going from a Squeezebox Touch through a Tube DAC and back into the DAC10H... A bi convoluted

I understand from reading that the Ref9v3SEs is a different design to the STA9 or STA10 and even the Ref20...
Just wondering 2 things before I make my next purchase...

1) where would you place the Ref9v3SE in the Amp comparison chart.  Is it closer to the STA9s or 10s

2). Will the DAC9 instead of the DAC10 with the Ref9v3SEs give a similar sound to a DAC9 and STA9 combination or do I have to go the full DAC9 and STA9x2 to get a true high end tube sounding solution?

Thanks in advance

John

Title: Re: NuPrime Amp Comparison
Post by: rustydoglim on 31 Mar 2018, 04:56 am
The Ref 9* sound is similar to ST-10. ST-10 is an evolution from Ref 9V3SE.
The 9 series are generally warmer.
The upstream devices are the most important with regard to preserving the details and resolution, so if your music preference is acoustic, then DAC-10H is the right choice.
Problem is that rock music has a lot of sound effects (especially electric guitar) so you hear too much of the unwanted details with an accurate amp.

STA-9 will be a good choice to try since it is so cheap and good.
Or wait for the new MCX-2 and MCX-4 (2 and 4 channels amp) series coming out late April. They are more refined than the current MCH-K38, designed to be all-purpose high-end amp.
Title: Re: NuPrime Amp Comparison
Post by: JackD on 31 Mar 2018, 06:44 am
The combination of the DAC-10/ST-10 will give you an "honest" representation of the music as the signal is presented to them. I use this combo everyday with Spatial M3 speakers and have for almost two years.  Changing your gear to make up for poorly engineered "Rock" music is folly.  There were only a half dozen "quality" engineers in Rock Music's hey day and most of them now are retired or extremely selective about the projects and artists they are involved with. If you are talking about current Rock music you are wasting your time as most of the production values are crap and there is nothing you can do about it as it is engineered to sound best on iPods with earphones.

The Ref 9* sound is similar to ST-10. ST-10 is an evolution from Ref 9V3SE.
The 9 series are generally warmer.
The upstream devices are the most important with regard to preserving the details and resolution, so if your music preference is acoustic, then DAC-10H is the right choice.
Problem is that rock music has a lot of sound effects (especially electric guitar) so you hear too much of the unwanted details with an accurate amp.

STA-9 will be a good choice to try since it is so cheap and good.
Or wait for the new MCX-2 and MCX-4 (2 and 4 channels amp) series coming out late April. They are more refined than the current MCH-K38, designed to be all-purpose high-end amp.

Do you mean Nuforce Ref. 9 series or Nuprime STA-9? I have the DAC-9 paired with Nuforce Ref 9 V2's and planning to "upgrade" to STA-9, always been a fan of a warmer, "analogue" sound, even if this combination sounds excellent. I think, for me, that if I choose Nuprime ST-10 it will be more of a sideway move.

Also, do you have more info about the new MCX-2 and MCX-4?
Title: Re: NuPrime Amp Comparison
Post by: rustydoglim on 16 Aug 2018, 05:01 pm
Ref 9v2 to ST-10 is a small upgrade, and with very similar sound characteristic.
For me, ST-10 is a better amp than STA-9 as I prefer my amp to be neutral and detailed.  STA-9 is warmer but less detailed than ST-10.

Jason, i would like to know if passing form Dac9+2x Sta9 to a pair of Nuforce Ref 18 (and probably a Dac 10H) would be considered an upgrade.
Someone offered the Ref 18 pair in exchange for my Diy speakers (he wants to sell them for 2.200 euro, i wanted to sell my speakers for 2500).
I'm working on another set of speakers based on Accuton drivers, as a side info. Those can get really power hungry.

Hello Rusty .. since I'm trying two new Reference 20 .. this is their first sounding week .. and I can choose for them or for the Evolution One .. could you tell me how much this new Evo is improving compared to the Ref. 20?
Well .. to be clearer .. I pay half price for the Ref. 20 (new but sold as demo units) while the new Evo is full price .. apart a little discount .. so I'm investigating about if the kinda double price is worthing
Thanks in advance for the reply
Title: Re: NuPrime Amp Comparison
Post by: rustydoglim on 14 Jun 2019, 11:53 am
Performance is subjective, especially at this high level.  All I can tell you is that Evo Amp is a newer design (for details please refer to the product page) and everything else is just better than Ref 20.
Keep in mind that Ref 20 is an incredible amp, and there is no particular weakness. So Evo Amp is just better in every way.
Is it worth the extra cost, that's subjective.

Some people drink away a few thousand $ a year in wine, take a vacation, or my online gaming pals spend a few thousand $ per year for the thrill of being the best, so it is a personal choice you have to make.

I quoted your sentence in an interesting part.
In your knowledge where and what I gain with the new Evo One?
By my small experience with the Ref. 20 I greatly appreciated the soundstage  a bit wider deepest and taller than the one obtained with my Parasound Halo JC1 and the Primare A32 I'm using from a year .. and the tonal neutrality... as good as from the other amps used.
The weird data is the power of the Ref. 20 compared to the Evo One .. in fact for the first NuForce says 200/8 and 400/4ohms .. for the second 240/8 but 330/4
Could this due to the new toroidal power stage compared to the previous switch module?

My rig .. Pass Labs X1 preamp .. TW Acustic Raven One TT with Graham Phantom II and Benz Micro LP cart. .. Whest Audio PS30RDT SE phono stage

Upgraded combo Philips CDD 882 Transport with Philips DAC 960 ..

Power Cords all Shunyata .. two Venom HC on amps and two Delta NR on pre and phono.

Some basic about power, current and voltage
V = I * R
P = V * I = V square / R
So, the basic assumption is that  when the impedance R is half, then power is double. 
I think so far everyone understand this elementary math :).
But in reality that's not always the case.

Let's use Ref 20 as the example:
200W at 8 Ohm is the spec for the amp.  400W @ 4 Ohm is the expected power if the power supply AND the amplifier are designed to scale up.  So far so good.   Now let's consider other alternatives.  What if we increase the capability of the amp to get more power at 8 Ohm.
Evolution One has 240W @ 8Ohm, better.  Could we have also increase the power of the amp and power supply to deliver 480W @ 4 Ohm ? Sure, but that would compromise the sound quality where we have to alter the design.   

Therefore, the overall power of Evo One has increased for most speakers (whose nominal impedance .  In all practical purpose, nobody really listen at max power, the typical listening power is less than 100W.

Got it! .. Thanks
Theorically on my Thiel CS 2.4 the Ref. 20 works better than the Evo ..

This is what wrote a famous reviewer about my spkr:

"I estimated the Thiel CS2.4's voltage sensitivity to be slightly higher than both average and specification, at 88dB(B)/2.83V/m.
However, despite Wes Phillips' conjecture that this speaker is not too hard to drive, its impedance plot (fig.1) indicates that the CS2.4 demands a lot of current from amplifiers.
Not only does its impedance drop to 2.73 ohms at 600Hz, but it stays significantly below 4 ohms from 100Hz to 50kHz, and there is a difficult combination of 4.5 ohms magnitude and –45° electrical phase angle at 80Hz.
Thiel CS2.4 owners should make sure they have a good 4 ohm–rated amplifier to drive this speaker."

I could recognize JAs review anywhere! He is a genius, and his info is vital to a lot of us that can't hear first hand and need to rely in other people's opinions and measurements.

4 ohms from 100 to 50K is the entire frequency range! Are you sure you copied that correctly? If that is true, these are certainly < 4 Ohm speakers! 600Hz is the very MIDDLE of everything you will be hearing, and that is 2.7Ohms.  Ouch!

Still, let's say all this is true (which I am sure it is, JA knows his stuf better that anyone else I have read in the industry).  You would still be getting 340 W from the Evos, which is probably more than you would usually need.  Would more be better? Sure, but only if everything else is equal.  So, let's say you had the same exact sound (not possible, lets just theorize for a minute) and you could get a 400 instead of 340.  Then yes, for sure it would be better.

But if the sound is less rich, or less detailed, or a bit more colored, or ... you get where I'm going at.  Perhaps it's better to have 340 great sounding Watts, instead of less good 400 W. 

So if there is any chance for you to try them out and judge for yourself, that'd be great.  Still, at double the price, I can assure you they won't be twice as good.  No where near that much in fact.  So if you are happy as is, you could save a lot of money and have both the amps and the $ wine Jason is talking about (or the PC games if you are into that! :) )

Best,
Rafa.

SHOULD I BUY STA-10 OR STA-10M?

I am looking for a power amplification solution for a stereo system which currently uses a Chord Hugo as a DAC and pre-amp.

This amplification solution needs to power my current Focal Aria 938 floor-standing speakers as well as my future speakers which are likely to be a product along the line of Focal Sopra 2 or Goldenear Triton Reference. 

One question that I have not been able to answer is whether to purchase a stereo amplifier (e.g. ST-10) or two mono amplifiers (e.g. ST-10M). I have not bought any NuPrime products before but am very interested.

I hold myself accountable for buying intelligently and might not be able to forgive myself spending twice the amount of money to obtain only a 10% improvement in performance.

Please advise. Thanks.

I hate to tell you, but (unless you own a really difficult to drive speaker) I don't think there is more than a 10% difference with just about any amp once you pass a few hundred dollars.  Don't get me wrong, there are certainly improvements out there, but I'd argue that they aren't really much more than 10% if that.  The high end is all about chasing that last 1-10% of improvements.
Title: Re: NuPrime Amp Comparison
Post by: rustydoglim on 22 Oct 2019, 04:50 pm
the difference is relative.  I am a coffee drinker, I buy only Jamaica Blue Mountain Coffee bean for drinking at home and to me, the difference between top tier coffee and "regular" coffee is day and night.  Same for sound quality.
I do agree that the difference between ST-10 and ST-10M is 10% or less unless you have a difficult to drive speaker.
BUT, we can't generalise that for the other NuPrime amps.  The difference between Evolution One and STA-9 would be huge in all aspects of sound characteristic.  And there are much smaller differences in quality (for example, comparing resolution) between similar range of amps (ST-10 and new AMG) but they differ in sound characteristic.

According to our chief engineer, he designed these amps and their desire characteristic through extensive computer simulation of circuit and devices during the design stage, not via trial and error. The sound characteristic is achieved by crafting class-A transistors preamp stage of the Class D power stage.

Sure, if you use these amps to drive a $2 speaker, they are going to sound the same.

@Mystic Dragon

I recommend that you go with ST-10.  You will be happy with ST-10.
And later if you upgrade your speaker, and want something much better, then trade in (I am sure your dealer will be glad to take one ST-10 at full price) for a pair of Evolution One later.

NUPRIME SALES CHANNELS

I live in Australia and hope NuPrime would establish brick and mortar or online sales channels that serves this market. 

While I would be satisfied to place an order for a ST-10 without having first listened to it, I cannot see myself doing the same when I consider buying a product priced at the Evolution One level.

It would be good to be able to buy MCX-2 type products from eBay or Amazon.

Yes we are, in fact, our engineer assisted the leading GaN device company to apply GaN driver to high freq Class D design.
It sounded different, yet to consider better.  We have become so good at combining Class A transistors with MOFET Class D power stage to produce different sound characteristic, so I think it is a learning curve that we have to go through to fully utilize GaN devices.

Hello, I contacted my local Nuprime dealer to order a pair of amplifiers for my Apogee Duetta signs.
I love the creamy, refined, complex and charming sound of my old Jeff Rowland Model 2. Although sometimes it lacks the crazy dynamics and demonstrative precision of my CLASSE CTM600.
The truth is that thinking of another type of configuration for bi-amplification I thought of a pair of ST10M in bass and the JR M2 in mid and treble.
A good friend recommended that for a coherent integration both amplifiers should be the same and there I thought that that option of the st10m would give me the opportunity to later add an ST10 stereo.
And although the basic question is whether two stereo ST10s would be enough for my ribbons , I was wondering if the new AMG STAs (with their necessary 200w at 4ohms) would be a sound match more in line with what Apogee do best.
Can anyone help me with your Apogee experiences?

Thanks and regards.
Title: Re: NuPrime Amp Comparison
Post by: rustydoglim on 6 May 2020, 08:33 pm
Power = Current X Voltage
The misconception is that speakers such as Apogee needs a lot of power, what it needs is high current type of power.  AMG is designed to output a lot of current, so it has no problem driving Apogee.  That means, at the same power, AMG has more current whereas ST-10 has more voltage.
Some people choose to buy amp with ridiculous power (that includes Nuprime MCX series) but keep in mind that amps that are designed for such high power > 300W give up some refinement and details. Higher power = higher noise in entire circuit and parts.  That's why most Nuprime amps don't go over kill with power.

You should have the same type of amps if you are going with bi-amping (perhaps one stereo amp plus two mono amps). I think ST-10/10M or AMG will fit your need but since they sounded different, I suggest that you contact Jye at support@nuprimeaudio.com with your music preference.  He is our product manager and golden ear.  Support is a shared email so you need to address your email to Jye.

Hi ! I am considering MCX-2 for my new Focal Aria 948 because they are known to be current hungry (up to 350w recommended: 2 x 21cm[8,27inches] woofers) and I like to listen to concerts, rock, ...
As I am not searching for very warm power amp, I heared that it would sound best for my needs (very dynamic, solid bass, ...).
I know I could loose a bit detail (as you said MCX are not as audiophile as ST-10, AMG STA or Evo One) but that seems to be the best compromise !
Does that make sense ?

I will provide a comment for A300 in the comparison but I think it is difficult to rank A300 in the table because it is an all-in-one device. Most people who have heard A300 and IDA-16 would comment that they sounded very similar.
Title: Re: NuPrime Amp Comparison

Patmania,

I have both the IDA-16 and an A-300. I used to own an IDA-8, but I gave it to my son as a housewarming present.  :( I really enjoyed that amp.

In my home using my ears, I do not think the A-300 sounds similar to the IDA-16. The A-300 is a bit warmer sounding, which I like. I haven't heard the IDA-8 in 1.5 years, so take my next comment knowing my aural memory isn't exceptional. I think the IDA-8 is warmer sounding than the A-300, but the A-300 sounds better while driving big speakers. The IDA-8 sounded a bit thin when I used it to drive large multi-driver speakers. The Bluetooth feature and Nuprime APP make the A-300 very convenient to use.

Just my two bits. Your mileage may vary.

You guessed right, we are considering an improved version of the A300 amp for IDA-32.
