I've had multiple icepower amps, including the PS Audio Trio. It was a solid amp, but I preferred different iterations using the same modules better, for example I preferred the Red Dragon Audio Amp-1s that sold for 1/2 the price of the Trio. One thing that bugged me about it...which was stupid I know, but the LED had a loud buzz, audible from the listening position ~ 7ft away. I listen at lower volumes so any sort of mechanical noise from gear is unacceptable to me, and I find noises like this particularly annoying.
Something from W4S or D-Sonic should be = to it if not better, but it depends what you are looking for. If you can find Murano, Red Dragon, or EVS they all should be better, speaking from experience with the Red Dragons and EVS.
