I response to nealk's concerns, the only reason that my center channel wasn't working was because the disc I was using was improperly labeled as a multi-channel disc. All other multi-channel SACDs play as expected. I was only able to use the center channel as a determining factor because I have no rears or sub presently. The Billy Joel Stranger CD has his voice emanating almost exclusively from the center channel. I hope this alleviated some of your concerns. I just wish I had realized that the disc was incorrectly labeled before I tore everything apart and bothered everyone here. Sorry to have caused any unfounded concerns.

Regards,
Matt
