Thanks to Keith's suggestion, I went out and purchased a few Radio Shack switcher boxes so I could hook up my new C222ES SACD player and the DVD-A player to the same amp. After checking a few SACD's from Chesky (David Johansen, Ana Caram, Wagner and Verdi) I was not getting anything from the center channel or subwoofer. These are multi-channel discs so I was wondering if they were mixed using these channels or not. It's probably something in my cabling but the DVD-A side has all channels firing. Any input would be appreciated.
