isn't the main feature of the icbm to provide proper bass management for 5.1 analogue input (e.g., from a multichannel sacd or from a dvd-a)?

the 950 has this built in. of course, the icbm is far more flexible -- so ideally, you would turn off the bass management feature in the 950 and continue to use the icbm. i would install it between the sacd player and the 950.
