If you need 7.1 channels you could get a modded Oppo with Vanity93 digi out board. You could run this straight digitally into a Trinnov MC8. The Trinnov will expand 5.1 to 7.1 using 3D remapping. You will have less flexibility than with an HDMI based SSP, but sonically the only thing equivalent to this would be usual suspect of >$25K processors (Meridian, Krell, ADA reference).
Standalone Room Correction Component
What are the current room correction components out there that only correct for room effects. No cost limitations, through cheaper is always better. I know there are some out there specific for subwoofers but I was looking for one that controls full range with delays, etc. for a 2ch to 7.1ch setup. Auto correction as well as manual correction would be a plus. Thanks.
