Summary: After 8 months the receiver lost all sound on allinputs. I sent it back to Denon and 6 weeks later, it was returned. The same problem recurred within 2 weeks and by now Denon had switched to an independent repair service, Panurgy. Again the This time the repair has already taken almost 6 weeks, and I have no receiver. When I called, they couldn't find the receiver with their own authorization number as they had given the same number to two people.
