Denon AVR-3300 5.1 Channels Receiver

Pros: Marketing Hype, Base Response, Tuner, Quiet Background during Music Playback
Cons: REMOTE, REMOTE and REMOTE, Weak Prologic Mode, Sibilance in Female Vocals, Lack of Warmth in Music Reproduction

I purchased the Denon AVR-3300 after being unlucky with two Onkyo Receivers. The TX-DS575 seemed weaker in supplying power to the rears. I upgraded to the TX-DS777 which was better but had the same annoying hiss from all channels, not to mention source...

Pros: Good power & fine Dolby AC-3 and dts processing
Cons: Build quality, particularly fan system

Pros: Great sound, good feature set
Cons: Audio switching reliability problem

I've had this receiver for a long time. I've been very happy with it overall, but I've got one particular problem: when switching inputs (e.g. from VCR1 to DVD), the audio doesn't switch immediately. If I don't touch it, it'll come back after some period of time -- sometimes immediately, sometimes 10 minutes.

I have the same problem when powering it on initially. It's been in for service, and they can't find anything wrong with it. Indeed, about half the time I have no problem at all -- the sound comes right on. Cycling power one or more times (sometimes up to 4+ times) does eventually solve the problem. However, if I just let it sit there, eventually the audio will kick on.

I've tried factory reset as well, to no avail. I can find no other reports of this problem anywhere on the internet, so it's likely an isolated incident, but it is really frustrating.
