I am a Foundation owner. The foundation will not yet decode DSD so if you want SACD you have to change your source (SACD Player or Bluray player) to output PCM instead of bitstream over HDMI. I play SACDs from my Oppo BDP-95 in this method. In this case Oppo is converting to PCM and sending it over the HDMI instead of the 7.1 output. Also in the case of the OPPO, if you change the HDMI output to AUTO instead of PCM or Bitstream, it does correctly switch from bitstream to PCM automatically when playing DTS HD MA versus SACD. I personally hope that they soon add DSD decoding to the Foundation so that I can compare OPPO decoding versus Foundation decoding.
