I just purchased a Denon 3802 receiver to replace a Yamaha 596. I have Paradigm Monitor series speakers. At any volume and in any mode, I have a consistant hiss coming mostly out of the tweeters. If I turn the volume all the way down (to the negetive infinity sign), the hiss goes away, but when I turn it up one click, the noise returns. The hiss does not seem to get louder if I turn up the volume. It is just loud enough to hear from the listening position. I had bought a Marantz SR8200 last month (that was returned due to the audio drop out problem) and the Marantz did not have the hiss. The Yamaha had some noise, but it was variable with the volume. Is this a known issue with the Denon or is there something I can do to lessen the noise? Thanks!
