Hi guys! Sorry to bother all of you again, but I desperate need help to solve some problem ( I believe so ) on my receiver. Yesterday while listening to music on 2 channels ( pure direct) on my Denon, it seemed to me that the sounds ( usually from the instruments) are a little out of tune. Hard to explain. Try to imagine when you are selecting the radio station and you get that noise. It is not too loud, usually it happens during the low frequency sounds of the audio. The dialogue is clear. Could this be caused by some bad settings on the receiver? Initially I thought it was only coming from the M22's but while listening to music on 5 channel stereo it seemed like it was coming this bad noise from the QS8's also. I need to do some more testing ( it is night here right now ). Any help will be appreciated. Thanks
