Why is it you all never talk about how well the equipment makes music? Isn’t that the reason for audio equipment? Do you listen to cellos, oboes, trumpets, etc. or do you just hear SINAD?
The musicians being recorded are the ones who make music, not my hifi.
I want my kit to reproduce their music without adding anything of its own.
For it to achieve that I look for distortion less than 0.1% (-60dB) and a noise level better than -80dB. It may be that better than that can be just discerned by some people but , for me, these differences are negligible and completely swamped by the differences in sound quality between recordings, which are W-A-Y more than those between different bits of hifi.
That actually means most electronics are good enough though some power amps may not drive some badly engineered speakers due to their load.
The only things actually capable of changing the sound audibly IME and microphones and microphone position (if you make recordings), speakers and speaker position and having enough power to drive the speakers you like without clipping.
This amp would probably sound transparent to me, though the one major thing influencing power amp SQ, tolerance of severe speaker loads, isn't tested here, or most other places, so maybe not.
