SACD seems to be going multichannel these days. Unfortunately my player doesn't have multichannel capability (Sony 9000ES). What happens when I play a multichannel SACD? It seems that if only the front L-R channels are reproduced, a significant portion of the recording will be missing. Do these discs contain a DSD "layer" with everything remixed to stereo? Or am I getting some sort of upconverted 16bit/44.1 KHz data?
