Excellent machine. Clear and accurate sound. Powerful enough with its 150 RMS/Ch for shake the entire house and capable of fine and delicate/rich sound when needed. I Rated 9 of 10 just because of it trend to become a bit /hotter/ than others amp i've tried so this baby need to have plenty of fresh air around it! In fact, it needs a dedicated fresh place among your audio gear. Visually it's beautiful...and builded as a tank! Love it!

Great unit, lovely LARGE meters, nice sound, capable of 110/220 Volts. Built like a tank.
A Yamaha unit with half the specs of this one costs US$5.000 in 2016
My favorite piece of gear.
