My freind just bought a Pioneer DV-563A-s wich is able to play SACD. We hooked it up and couldnt play SACD with the COAX digital connection, only with stereo RCA hookups. Is this normal? Its the first time I have tried SACD so I know nothing about it. HELP!:b Is the 2 channel hookup better than the 5.1 or should I just get 6 cables and go that way?
