I've had my 3802 for a few months now and haven't experienced any problems. But the other day, while watching DirecTV, I had my ear near one of the surround speakers when the unit was in ProLogic II music mode. The signal sounded "warbly" and unstable. This was the case with each speaker other than the center channel. I tried the DTS Neo:6 setting and experienced the same thing. However, when playing back a DVD, the speakers don't exhibit this problem--signals from each speaker sound solid. Problem also doesn't exist when using Denon's 7.1 theater mode. The warble is not noticeable from my normal listening position; only when you get within less than a foot of each speaker. I'm not terribly concerned since it's not that noticeable, but I was wondering if anyone else experienced this and knew anything about it. Any help would be much appreciated. Thanks.
