Bob, I have no experience with room mode correction (ARC) except for LF ARC for a pair of subs, so I can't comment on the relative merits of ARC v superior analog. I think with either the 95 or 103 Joe can take video from HDMI-1 to his TV/monitor/projector and audio from HDMI-2 to his processor. SACD output can be set to DSD, given the 9.9 is doing speaker configuration and so forth. I'd guess, but don't know, that the video processing of either Oppo may be superior to that of the 9.9.
There are lots of posts here and at AVS about the fine quality of analog from the 95 and 105, so I'm not the only one who's fallen into the trap. I have no idea how many sources Joe needs to accommodate, but I would have bought a 105 and used it as the processor instead of the 9.9, taking its analog directly to the amp. A 105 takes digital input, including HDMI and asynchronous USB, and does speaker configuration, bass management, and volume control. A veritable Swiss Army Knife for AV.
