I apologize if the conversation between me and XM confused things. I think you will see improved results running HDMI from your OPPO to the M-975. Analog out of the M-975 to your amplifiers/subs just as before.

I would be interested in hearing your thoughts on any differences. I find the M-975 and OPPO to be an impressive combination.
