My apologies if I may be simplifying the issue, but here goes ... I have a 2 channel set-up (Musical Fidelty A3 integrated amplifier) with a SONY SCD555ES SACD changer. I just put in the SACD and just press play. The SONY defaults to the SACD layer ... said differently, you have to go out of your way to select any other layer (in the case of the hybrid SACD). I have both stereo & multi-channel SACD's and have never noticed any tracks not playing, or anything unusual for that matter. If I am missing something ... please feel free to correct me. Regards, Rich
