Well, the Atma-Sphere 100 wpc class D monoblocks are very fine amplifiers. In listening to them I cannot identify anything in its sonic signature that screams class D. I have been surprised that the class D monoblocks seem to power my Aerial Acoustic 7ts effortlessly. The sonic signature of these amps is clean, pristine, non-fatiguing with very solid imaging. Nevertheless, I could see how it’s sonic signature would not be for everyone. While avoiding the nasties of solid state, is it tubelike? Perhaps it has some sonic traits of a very good hybrid or contemporary non-romantic tube amplifier.
I bought the PSAudio monoblocks and these amps virtually simultaneously. I like them both very much as neither amp will be returned or put up for sale.
