I've had an NAD 752 for about a year now, and have been very happy with it. I moved recently, and took great care not to damage the NAD or my speakers during the move, but now I'm having a problem.
I seem to have lost the left surround channel. Does anyone have any advice before I approach NAD about service? The other 4 channels are working fine, and when I connect the L surround speaker to another channel it works, so the problem is not with the speaker. I've got fairly new Tara Labs cable, so I don't think it's the cable, either. Any advice?
I would try leaving it unplugged for say 24 hours and then plug it in to a power conditioner/voltage regulator. The NADs can be very fussy when it comes to the quality of power. If that doesn't work it's time to return it for warranty work.
