Now when doing this -- again because there is no audio processing -- the speakers are treated as Large (no Crossover). And so there will be NO SUBWOOFER OUTPUT. There's no LFE channel in the 2.0 layer of course, and there's no bass being steered to the Sub from the mains. The upshot is that you don't have to fiddle with the volume setting on the Sub because the Sub will be silent! Voila!
Bob, when playing DSD direct to analog from 5.1 sources, do all the settings for speaker distance and trims remain in place? I ask this because you say that for DSD the speakers will be defaulted to Large. I have currently set up my speakers to small with -6DB trims to the xlrs fr/fl and I have adjusted the distances to match my room, but I am wondering if all of that is for naught?
Another thing, now that I have had the unit for a couple of weeks, the bass is increasing like crazy. It went from pretty anemic out of the box needing about DBs increase (+15 out of my Fathom F113 + 3db trim from the oppo) for music and movies. Now, for movies I had to take out the +3 DB trim altogether and for movies I am at +12DBs or less (depending on the movie, Prometheus required about +8 only). Music is about the same. Really remarkable break in. I experienced the same thing with the 95, but it took longer than 2 weeks.
When using DSD, the multi-channel Analog Speaker Configuration settings are left unchanged -- they are just ignored.
I suggest "Stay in Tune with PentaTone", SACD, tracks 43-48 for confirming volume trims with SACD Output PCM vs. SACD Output DSD. (NOTE: The Subwoofer test track, track 48, is about +4dB hot on that disc.) But Crossover processing, distance adjustments, and down-mix CAN NOT HAPPEN while using SACD DSD-Direct-to-Analog Conversion. If you need those, then you should use SACD Output PCM instead.
Now if you are playing the stereo layer of an SACD, and don't care that the full frequency range will go to your main speakers (i.e., no bass steered to your sub), then you may very well find you can use SACD Output DSD -- i.e., try it and see if you like it.
Note that distance settings are less important for music playback since there are no visual cues to indicate that placement of sound BETWEEN speakers might not be an exact match to action on screen. Phase management for the Sub is also not an issue since there is no Crossover processing.
