I purchased a NAD C320BEE for a second audio system and all is good so far! I had purchased one a couple of months ago which was producing static sounds through the speakers, also it was running very hot and had a burning smell. I immediately returned it. I decided to give NAD a second chance, very good amp for the money I just hope the flaw that I had experienced on the first purchase will not reoccur! Well, im off to listen to some music!!!
