I came across this very nice 5-ch amp recently. Very powerful, massive, great power supply. As you can see, this thing is built to be utilized to the fullest.
5 channels that can all do 110W@8Ohm continuously, and 120W@8Ohm stereo. The unit weighs 70 pounds! And it is 4Ohm stable.
Amp is in great shape.
Asking $350.
