Initial impression of the Nuprime ST-10 amp

I have a very fine McCormack DNA .05 Deluxe amp, a Don Sachs 6SN7 preamp, driving my Spatial Audio M4 Turbo S open baffle speakers and today swapped the McCormack amp for the ST10 amp.  Right out of the box, the ST10 is quite an amazing amp.  It is very powerful and yet quite delicate in its rendering of sound. To my ears, it is somewhat tipped-up in the HF compared to the McCormack amp, and at this point seems to give up a bit of the LF rendering of the sound to the McCormack amp, but overall, it has lots of inner detail and a sublime mid-range.  It has not a bit of harshness or dryness that I have heard with earlier Class D amps... it is very musical with the sound flowing effortlessly.   I will post my impressions after it has been run-in for a week. My initial impression is that for $1600, this is a very fine amplifier.

Cool, whitestix. I really enjoy my NuPrime IDA-16. If the ST10 is anything like my IDA-16 it will take a few weeks for it to really start settling-in.

Based on my experience with the IDA-16 I believe you are in for a good time, enjoy.

Cheers,

Scott

That's great. If it's anything like my IDA-16 it will continue to open up and fill out. You may have some peaks and valleys along the way. Around the 300 hour mark my amp really started to bloom. Even now passed the 500 hour mark it continues open up and settle in. Have fun.

Cheers,

Scott
