Thanks for the reply Gonk...one more question.

If the 990's Bass Management is more than adequate, would it be possible to insert the ICBM between the DVD-A SACD player and the 7.1 direct input of the 990 to maintain pure analog (and accept the loss of delay settings) for these sources? That way I could eliminate a DAC process and preserve the analog signal. I would assume I would then set all speakers to large and sub to "on" for this and bypass the player and the 990's bass management functions.

I use would then use a separate DVD player and the bass management of the 990 for movies, digital input from a CD player and the X-Box etc. Here is the rub... Can I have different speaker settings (small, large etc) based on input used? Given the above scenario, would I have to? I might be confused, but I think I would.
