Query: When it works, sounds great

I had this receiver for 28 days, about the 20th day the volume spiked to maximum on its own and almost blew my speakers. On the 28th day, the sound degraded to that of an old AM radio just before it stopped sending sound to the speakers completely. It came back to life on and off a couple of times before I pulled out every cable and boxed it up. While it was working it sounded very warm. powerful, and the imaging was great. This unit gets hot, much hotter than it should. I've since read the reviews at audioreview and wish I had before purchasing this receiver. I think H/K dropped the ball on the avr45, avr65, and avr85. I went to Circuit City after XMAS and saw 6 returned AVR's on the shelves, 45's , 65's and 85's. That told me something. I was willimg to live with only one optical input, no DTS and no A/B speakers, but not after the gremlins took hold of it. Sounds like a processor problem throughout the line. Maybe the new 300, 500 series will be like the H/K of old.
