Since this is probably the last word on the 990, I think it would be useful to see a bass management matrix for the 7.1 direct inputs. I know what happens if you set all the speakers to SMALL and the SUB is essentially yes. There are many other possible combinations, but short of a whole matrix, I do have two specific questions.

If one sets the center and surrounds to SMALL with appropriate crossover frequencies, and the fronts to LARGE, what actually happens to 7.1 direct for the different sub settings +SUB, LFE or NO?

Are there any combinations of settings for any/all the speakers (size and delay distance) when the 990 would not apply the extra A/D and D/A to any of the speakers (like the fronts) and would pass any parts of the 7.1 direct input through as completely unprocessed analog?
