Fantastic amplifier, massive amounts of power more than it's rated for, around 180 Watts Per Channel at 8 Ohms at 1 KHz. Superb build, not too hard to work on, easy to find all the parts for, amazing clean sound. Decent Phono Preamplifiers, with good sound, though they're much quieter than a 2 Volt Line-Level signal. Headphone amplifier pulls off the mains for the amp, so you get tremendous detail and definition. Amp's only downside is that it gets very hot after a while.
