I'll be taking my NAD T762 in for a look while under warranty, the owner of the store said they would take a look, but 'write down on paper the problems you have been having' was a very explicit instruction. The unit freezes at times, and when coming back from a 'drop out', sends a chilling or disturbing signal to one of the speakers (it varies which speaker gets it, but doesn't happen all the time). All in all, real happy with the sound it puts out, just wanting to get rid of the nuisances (and perhaps an upgrade to a T763 at a reasonable price). But my real question is should the receiver still activate the subwoofer if your listening in Dolby 5.1 and speakers set to 'large'? I've noticed sometimes it does, sometimes it doesn't. (I would think it should, but I've been wrong before...) Any advice on whether this should make the problem list is appreciated.
