My Denon 3808CI is several years old and I love it. Recently, however, I have been noticing sporadic crackling and distortion, mainly with dialogue reproduction. There doesn't seem to be any rhyme or reason to it, and I can't figure out what is causing it. Speaker connections are solid, as are HDMI connections. It happens almost exclusively during playback of Blu-ray movies (I have the Oppo BDP-93, but the problem started before I got this player), but I just starting noticing it occasionally on a playback of a recorded program on a Directv HD-DVR. Someone told me it might be a bad HDMI cable or a bad HDMI port on the Denon. Was just curious if anyone else has experienced anything like this with their Denon 3808. Any input on causes and/or fixes would be much appreciated. Thanks!!
