Yes gonk. For my use that would be perfect. I started to write that in but I would want it as an option along with the others. The problem I foresee is what the PCM signals would be. The main L/R and surround L/R's would be OK as pairs but what about the sub and center? Separate? Would they all be separate? I'm not sure but I don't believe the PCM stream can handle greater than 2 channels ata time (anyone know?) I suppose that could be a PCM pair as well but I guess it doesn't matter as long as its accessible.
I assume that other multichannel processors would be on the market, i.e. multichannel EQ and the like, so having a native DSD or Bitstream would also be nice.
But for now, multiple PCM channels after decoding would be great for me.
