I was going to put this in the old thread it was discussed in, but thought it might be better in a new one. After a couple months of mostly superb performance with just a couple glitches, I had to send it off for warranty repair. The problem was that more and more, when I would turn the unit on, I would get some odd audio. Sounded like an old AM radio with a bad signal. Lots of noise with fairly quiet source audio. They tested and returned noting that all was as it should be which concerned me. But I had always felt that the audio issue was HDMI related but couldn't quite put my finger on the actual problem. When going through the testing of all inputs and such, I noted that when the bluray player was selected, the menuing on it wouldn't hold sync. It would show, then reset, show then reset, but if I put a disk in it would play it just fine. So I thought that maybe one of the HDMI inputs didn't like that BR player, so I switched some things around, even changed to a new HDMI cable, but the problem followed the BR player. Finally after looking at the video menu selections and how they were set on a working input/source, I noticed Video Output Resolution which was set to 'auto'. This AVR will do up to 4K conversion and I thought why not set it to a fixed output resolution to see what happens. Set the AVR for that HDMI connection for the BR to 1080p, reconnected the BR player and all was good. It seems the 'auto' setting does some negotiating and for whatever electro-magical reason the Sony BDP-N460 and the 2113ci just couldn't get together with syncing. My thinking is that when I had it before sending it off, the constant reset of the HDMI sync caused something to overheat (or something) and it affected the rest of the operation. Or at least I'm hoping that is what was going on. I'll know better after a few days of operation. One thing I noticed while the Denon was off to the repair center and I was using my HK AVR-247 was the the HK has more headroom when 7.1 sources are in play, mostly because of the very hefty power supply I suppose. Overall the Denon sounds much better with an excellent soundfield that the HK just couldn't quite do. Most of that I think comes from the Audyssey EQ. The HK has a much simpler EQ setup routine all done from a single spot, while the Audyssey requires at least 6 spots of testing.
