Doug said: Ultraclean sound combined with a subtle richness, fullness, and sweetness in the top frequencies of the audioband that’s quite unlike the sound of any other solid-state amp I’ve heard.

Read the SoundStage! Hi-Fi review.

The gist: Lots of power and finesse in Simaudio’s best stereo amp.
