I have mentioned this once before - I think to Boa. I have somewhat clarified the problem.
When playing a CD on 5 channel stereo or using the Matrix, etc surround effects, the center channel sounds terrible with a lot of distortion. Sounds like the horn is "vibrating" with the highs. The mains (rb-5) and rears (rb-5) remain sounding great. With four rb-5's, you can imagine why I prefer 5 channel stereo.
So I thought the problem was with the RC-3. However, when I switch to Dolby or Neo 6, the center channel "comes to life."
What gives? Defective amp in the 3801? Or does the 5th channel just sound bad due to its creation by the receiver, and so live with it?
Anyone else toggle the two (5ch and Dolby) with a CD and notice a difference? Most prevalent on less than stellar recordings.
