I read a little more and found your point Rick (sorry, I should have done my home work prior to my previous post):
In addition to performing this mandatory function for DVD-Audio or SACD, the ICBM may also substitute for a pre-amp's own bass management circuitry.
However, I would probably think that a great piece of pre/pro like Rotel RC-1070 should have great bass management features. I believe that you have the same preamp. Did you notice any improvement with your 2.1 setup after purchasing the ICBM?
It seems this one retails for $249 plus shipping. Is that right?
