^Bill, just to clarify, you are getting DSD decoding in the 4311, regardless of whether you are in Direct Mode. because you have set the Oppo to send DSD and the Oppo detects that the AVR will acccept DSD. BTW, my level-matched comparisons between send DSD vs PCM from Oppo to Denon have consistently revealed a decided SQ improvement sending DSD.
Thanks for that information and that you find DSD to be the best setting. I'm going to do some more comparisons tomorrow. I want to see which will sound best in my room DSD Direct or Stereo with Audyssey for 2CH SACDs.
For your information Bill, according to Bob Pariseau (who IMO is the most knowledgeable and helpful poster in the Oppo 93 thread) on SACD playback the 93 's LFE channel is output at a different level depending on whether you let the Oppo decode it (sending it PCM to your AVR) or let your AVR decode it (DSD Direct). IOW the bass management in the 93 is different in the two cases. Pretty sure if the 93 decodes it (versus the AVR) the LFE channel is 10db louder. I noticed and verified this with my set up (93 to 4311) about a year and a half ago and I let the 93 decode DSD since this seems to properly match up with playback of other 5.1 material in the LFE (.1) channel. Now it's possible Oppo has changed this in a firmware update since then but I can't recall mention of this and I haven't gone back and re-checked it anytime recently. You might query Bob on this point on the 93 thread and check it yourself on your system.
