Bill. I glanced at the 2930 manual and many of the statements about DL and settings are very similar as for the 4010. But in both manuals, it is pure Denonese, so who knows?
My best guess is that just like in my player, the 2920 SACD signal will carry over DL in bitstreamed DSD, but you'll not be able to opt for PCM. And thus you'll be able to select DSD Direct in the 4311 if you like. IRT 2910 HDMI connection, it appears that like my player, you'll not be able to send DSD via HDMI at all, so will not be able to duplicate your Oppo tests. We'll see, mebbe you'll figure this out better than I. .
Thnx for that detailed report, Bill. It'll be interesting to find out if this occurs with DL. I hope you can figure out how to toggle your Denon player from bitstream to PCM via DL. Also, if there is such an option, could you also please check bitstream vs PCM via HDMI (DL disabled).
Sorry for not going back and reading all of the comments on this combination, but I may be able to add some helpful information.
My 2930-4311 audio connection is via DL3 only. I hooked up video via composite and removed HDMI link out of paranoia Audio setup on 4311 is set to auto decode (necessary if you ever plan to play a regular CD). Other than customizing Audyssey/EQ settings this is all that's necessary on the 4311 for proper configuration.
On the 2930 there is an SACD configuration button on remote and front panel. Mine is set to MULTI, the heirarchy of 2930 will revert to the next lowest setting in this order MULTI-STEREO-CD. The latter switches the PCM, the former two remain DSD. To switch to PCM output simply select CD for this configuration.
You will not get DSD via HDMI, both the manual and my own testing have verified this (yes, I'm stubborn).
A couple of tips. It took me awhile to figure this out, but you cannot select DL in the 2930 configuration with a disk in the player. Once DL3 is selected there are no audio configuration changes that you can make unless you want to turn compression on. Also, if you turn off the display of the front panel of the player it will also turn off OSD, which naturally is necessary for setup.
Now back to the boards to find out just what the heck this LFE thing is all about.
