NAD products are not as disposable as most big-box electronics... ...i suppose it depends mostly if you have a decent repair shop in your area (because shipping costs can take a big bite out of any repair budget). Also, the repair shop does not necessarily have to be an Authorized NAD outlet to get good work. I would google the NAD model number and symptoms and look through the myriad discussion forums to try and narrow the possible repair schemes.
