    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?

    Dave, it should be disk dependant. Most all SACD's have a high resolution 2 channel stereo SACD layer that your player should be playing. How are you feeding the audio outputs from the player? You need to be going to a fully bypassed preamp input or you may then get an upconverted mix (but that is probably dependent on how you set your 9000es up).

    Thanks Charles. That's kinda what I thought. That means there are actually three programs on every disc:

    multichannel DSD
    stereo DSD
    Redbook CD (for compatibility with conventional players)

    I am running both digital and analog to my pre-pro (Lexicon MC-12). For redbook CDs, I select the "CD" input which I have programmed to use the digital input. For SACDs, I select the "LD" input which is programmed for full analog bypass. Of course, this means I give up bass management on SACDs but since I have reasonably full range front L-R (-3dB @ 32Hz in-room), it's not a big problem.

    Dave,

    Stereo is required for SACD. Multi-channel and Redbook CD are optional.

    John is correct. Until recently, all Sony-issued SACDs are single layer discs, which means you can't play them in a regular CD player or DVD player.
