My next goal is to purchase a new HDTV and probably an OPPO BDP-10x to replace my old Panasonic DVD. My plan is to feed whatever cable box I have then into the OPPO to take advantage of its video processing and DAC's and then feed the audio signal into the 990 via 7.1 analog. I plan to use the SMS for bass management.

I am not going to use the 990 for video switching but will leave it connected via component.
