I too have tried to set my Oppo 93 to send PCM to my 11a. I set the associated 11a HDMI input to PCM rather than bitstream in accordance with the Cary manual. The 93 displays SACD PCM, but the 11a displays DSD. Being able to link with PCM is important because, as I understand it, DSD does not carry information for bass management unless the disc has a .1 channel, whereas PCM carries that information without a separate .1 channel. Few SACDs have a .1 channel.
