Good sound; unreliable circuitry
I've owned this amp for a total of 3 years and, overall, I've been pretty happy with it except for the last couple of months. For some reason. it randomly chooses to shut down into stand-by mode (the little red light next to the power switch will flicker on and off). After repeated checks concerning my speaker wire connections as well as unplugging each individual unit from the amp, I still can't figure out the problem. It HAS happened DURING playback but for the most part it will go into stand by as soon as I turn it on. When I turn it on a day or two later, it will be fine. My last stereo amp was a Yamaha (model number not remembered at this point) which lasted over 15 years and i'm very disappointed with this unit giving me issues after only less than three years of use. I can't afford a new amp at this point and am very wary at trying to get it repaired (with the problem not going away after "repair") so I'm basically stuck with it. Again (with supplementation of a dbx 215S EQ which I bought from Crutchfield), this is very good, clean sounding amp. but in all honesty, I'd be very wary of buying any NAD products again. I should have bought another Yamaha.
Pros: Good, clean sound,
Cons: After less than 3 years use and no obvious reason, goes into stand by mode.
