I just bought the Pioneer DV-563AS, mostly so I can play SACDs. I was very surprised to find that it required hooking up RCA jacks to play SACD. I have the unit connected to Yamaha HTR-5550 receiver. I am unsure how the Pioneer should be configured to play SACDs in multi channel mode (and yes the SACDs I am trying are that way).
I am also unclear of setting the receiver should be on to get the desired outcome.
