I will never even consider a piece of NAD equipment again. I had the 763 receiver and when the system died (sound through anything involving the DAC was almost silent out of the right side of the unit) within the warranty period, they looked at it over the course of a month, told me there was nothing wrong and sent it back. I hooked it up again and a few weeks later the same thing happened. When I brought it in again they wouldn't look at it unless I paid them for the diagnostic, etc. because the warranty had expired when the unit was with them the first time. Yeah, I am never buying from them again.
