NuPrime DAC-9X and STA-9X review by Alpha Studio

Thank you Alpha Audio for a detailed and professional review of the Nuprime DAC-9X, which begins at 1:12:20 in the video. The reviewers start by discussing their setup, evaluation criteria, the use of a re-clocked SPDIF signal, and their decision to avoid using a power conditioner. They highlight the DAC-9X’s exceptional detail, extreme separation, and impressive performance at its price point, noting that Nuprime has expertly implemented the Sabre DAC. The DAC-9X reveals background vocals remarkably well, a feature unexpected in its price range. Overall, the reviewers find it to be an excellent value, delivering performance and expandability comparable to more expensive integrated amps when paired with the STA-9X.

NuPrime AMG STA-SE review by HiFi-Advice

Nuprime AMG STA-SE ($2295 USD / $2595 Euro) won HFA Award from HiFi Advice. Christiaan Punter is a highly respected reviewer who has evaluated the Nuprime ST-10/10M, AMG STA, Evolution STA, and AMG STA-SE.

Here are the notable statements from the review:

The AMG STA-SE does not fall into this trap and walks the fine line between maintaining control and stability on the one hand and providing emotional involvement on the other. This is one of NuPrime’s most alluring qualities: their Class-D products do not sound like other Class-D products.
……….
The AMG STA-SE is a different animal. Given its ballsy and confident yet liquid presentation, it’s perhaps more like Class A than Class A/B. More specifically, no longer Jeff Rowland-esque, in some ways, it now sounds more like a Pass Labs amplifier.
……….
….the AMG STA-SE sounds more natural than all other Class D amplifiers I have heard…..
