If you've read any of my previous posts, you'll know that I'm basically very happy with my AVR300/27A combo. That said, I have a minor problem with background noise which I would like to get resolved. The noise is noticeable at relatively high gain (say, 75 db) with quiet source material (and when nothing is being played). Some info: - With everything connected, the noise is present on all inputs...it's worse on analog inputs than digital but is not absent on any of them. - I removed all cabling except speakers and found that the noise was completely gone, so I suppose that rules out the AVR300 as the source. - I began recabling, starting with the subwoofer, then moving to the DVD recorder, the VCR, etc. - I found that the VCR was the main culprit and subsequently re-routed its outputs through the DVD recorder. - With the VCR removed, the amp stays silent even at maximum gain UNTIL I recable the 27A. The digital output is fine, but if I connect even a single analog cable (I have 8, 6 for DVD-A and 2 for stereo), the noise level increases. It's not as bad as it was before, but it's definitely still there. The interconnects are decent (MIT for the fronts, blue jeans for the others) and the problem occurs regardless of which cable is connected, so this would seem to rule out the physical cables. - The ground lift switch has no effect. So...I'm stumped. Any theories? Ideas? Thanks.
