“…Larger-scale dynamic shifts are rendered with conviction while lower-level nuances still come through with clarity.
The soundstage is impressively wide and nicely layered.
…
We are equally pleased to report that the DAC-9X’s preamp section is a good one. Judged by price standards it displays an impressive degree of finesse, delivering a well-resolved and musical performance.
…
The NuPrime DAC-9X is a talented and versatile product that is capable of delivering pleasing results in a wide range of systems. Match it with the care a product at this level deserves and it won’t disappoint.”

“As it turns out, I did not have to worry. With the Evolution STA in the system, there was no perceived loss of bass control. Indeed, there was the same control, but with a more detailed bass than the AMG STA’s. As cliche as it sounds, across the frequency spectrum, I was hearing things that I swear I had not heard before with the AMG STA’s. The Evolution STA was able to do all this while retaining the detailed yet smooth sound signature that I really like about Nuprime amplification. The Evolution STA represents the best class D implementation I have heard. This is a truly end game type amplifier for me.”

“This is NuPrime at their very best – the new STA-100 is their most affordable power amp yet, a radical internal design and fantastic sound quality that will have you wondering how such a small box can produce such a big sound.
…
The STA-100 is real high end – it’s expressive and detailed, pacy and involving. And when NuPrime describe it as having ‘explosive power at high volume’, they aren’t kidding; this baby can go! And it just gets better as it warms up…The background noise levels are vanishingly low.
…
I’m struggling to find a downside…But more importantly this model is a welcome addition and delivers an authentic NuPrime experience to a whole new audience.”

“How does 120W x 2 worth of hybrid Class A + Class D amplification for $649 sound? How about running a pair of them in mono mode for a total of 290W per channel? You’d think there must surely be some compromise involved yet try as I might I just can’t find it.These little fellows offer richly textured sound with an excellent soundstage and deep low-end extension, all in a tiny package. The amps build on the classic NuForce Reference models of yesteryear, but take on a subtly relaxed flavor where those older models could be a bit high strung. This is a hugely crowd-pleasing product worthy of serious attention despite its affordable nature”

“Combination of energy and musicality
…NuPrime’s achievements have earned an excellent reputation, including its digital amplifiers, including the STA-9 model on power stages using a brand design and preceded by class A gain stages. Listeners get excellent sound results, which should reconcile the advocates of opposing opinions on the amplification classes!…”
