Where did this hypex integration come from? Don't make me puke
Of course Nuprime amps are all designed by Nuprime. We do not buy from Hypex or any other amp module.
In fact, we will be introducing our own amp module for the DIY and installation marketing in December.

Interesting! By any chance could one use the upcoming amp modules to create a self-powered speaker?

Yes.
Basically it is a "naked" STA-100 with 20% more power with a mounting bracket/heatsink.

Hello
what about an high-end streaming DAC/preamp (target early Q4 2023) ?

hello
At the origin of my purchase I listened to the Evolution 2 with Focal Utopia, it was breathtaking afterwards for my less demanding speakers, and one. smaller budget because I wanted 3 amps, I tested the nuprime AMG One in the store and I don't regret it. when I was talking about hypex it's linked to the hypex hype on many sites, it's true that its modules when they are well integrated they are transparent and have no breath, but often I find that they are missing soul. this nuprime amg one is more transparent and therefore more versatile than amg STA9, AMG STA for exemple when you listen to all styles of music and not just vocal jazz. we are perhaps less tube type like the sta 9 but it still has this warm side. we are therefore in an ideal compromise

That has been pushed out to mid 2024. We hope to announce something at Munich high end show 2024. May be sooner.

Regarding High End streaming DAC mid 2024.

In which series/level will that be in?

I am now testing Evo DAC-2, and it is amazingly good, nothing less.

But I am wondering if it would be better to wait for the upcoming streaming DAC?

rustydoglim · « **Reply #48 on:** 4 Jan 2024, 07:02 am »

The Evolution series will have two streaming models: IDA-32 (we talked about this for sooooooo loooong, sorry) and streaming transport. I am not sure integrating a streamer with a high-end Evo DAC-2 is a good design choice. The product will be more expensive, but less in performance.

I have two questions about Evo Two amplifiers.

I'm enjoying ST-10M for some years. Wonderful amplifier. Is the Evo Two, as far as sound signature, an upgrade to ST-10M or does it go in different direction?

Second, what is the peak output current and will Evo Two drive 2 Ohm loads?

Many thanks, Srdjan

rustydoglim · « **Reply #50 on:** 5 Oct 2024, 07:03 pm »

Forgot to answer this. In general, Nuprime amps don't lean towards overly warm, "sweet", or bright sound.
See https://nuprimeaudio.com/guides/amp-comparison/
Evolution Two as the highest performing amp in Nuprime product lines, has the best of various sonic characteristics except that it is not as warm as AMG STA, STA-9 etc.

It is listed along with ST-10M, AMG One, etc as neutral amps.

Nuprime amplifier generally can go down to 2 ohm momentarily and as long as the current is less than 7A, it won't shutdown for protection.

New member, long time reader...
Currently using 2xSTA-9 and are very happy, both out of curiosity and upgraditis I am looking to try either an old school class-A amp, or another NuPrime...
Looks like the AMG-One would be a good step for me, large enough to notice a difference.

What are some other experiences been moving from STA-9 to AMG-One?

Check out the comparison here: https://nuprimeaudio.com/guides/amp-comparison/
The change in sound characteristic and quality is huge in all aspects going from STA-9 to AMG One.

Indeed the 2 are on different levels in most categories, just what I need to figure out what I like better. I’m not set on ”my” sound character yet and hope that the difference is noticeable.
I do like to hear all the details, better frequency extension is also welcome, maybe I will find the next ”bottle neck” in my system 😬.

Currently running an AVM PA5.2 tube-hybrid pre amp and QLN signature 3 speakers. Also looking to upgrade the digital front-end from WiiM possibly to a Stream-9… becoming a NuPrime fan boy

AMG One and AMG STA-SE have distinct differences. Compare these two in-depth reviews from two respected reviewers:

@rustydoglim
The Evo II is now about 2 years old.

How is the Evo II SE different?

Is the Evo III coming out soon?

rustydoglim · « **Reply #56 on:** 19 Mar 2025, 01:50 pm »

Evolution Two-SE is our new flagship amp. The difference is mentioned on the product page.
The changes is quite noticeable over Evo Two.
If you purchased Evolution Two within a year, we can offer free upgrade but you have to pay for the round trip shipping to Taiwan factory.
If more than a year, we charge a token service fee of $100 for the effort plus the round trip shipping.
If you have other amps and are interested in trade-in, contact us by email sales@nuprimeaudio.com and let us know where you are located and your current amps.

Are you kidding, it took a long while to come up with a major improvement:
"Compared to the Evolution Two, the Evolution Two-SE features a new ODC circuit that enhances interference handling by a factor of 10, resulting in improved total harmonic distortion (THD) performance."
That's very difficult to do at this level.

We are confident that the Evolution Two-SE can rival the CH A1.5 (€30K) amplifier in every aspect. When the Evolution STA was last reviewed, it was considered on par with the CH A1.5—excelling in some areas while falling short in others. With the Evolution Two-SE, we have worked diligently to refine those weaknesses, creating one of the world’s finest amplifiers.

Sorry I didn’t realise Evo 2 was upgraded to Evo2SE.
Great that you offer a factory upgrade service.
Can I ask what the noise floor of the Evo2SE is?
Rob Watts is not a fan of Class D because he says the noise floor of most designs is around -120dBA whereas his Chord Dave is at -178dBA.
Not sure if that is relevant but he implies ClassD can’t fully reveal what his DAC designs are capable of.

rustydoglim · « **Reply #58 on:** 19 Mar 2025, 02:57 pm »

high end audio is both an art and science. That's why we never emphasize on some absolute number and claim that it sounded good because.....
Go find out if -178dbA is realistic or not (ask ChatGPT, Grok, etc). You can't even measure this level of noise floor.

Here's what ChatGPT said about -178dbA: Radio astronomy and quantum physics labs (e.g., LIGO gravitational wave detector) can achieve noise levels approaching -180 dB in highly controlled, cryogenic, and vacuum environments

HeeBroG · « **Reply #59 on:** 22 Mar 2025, 05:51 am »

Very well. I have just placed an order for the EVO II SE's with my dealer.
I'll touch base when I receive them.
