I have a Yamaha RX-V2095 as a pre-amp, and a Parasound 2205AT power amp. I have my ICBM between the pre/pro and the amp. Until you hook it in, you can't really judge what kind of a difference the various bass possibilites of the ICBM will make. You just need to noodle around with the settings till you find the ones for your system. Outlaw gives good starting point recommendations in the manu.

I'm using NHT 1.5's all around, with an NHT AC-1 and a SubOne, so my needs were different from yours, but I liked the ICBM enought to keep it. At $249 and a 30 day trial, it's painless enough.
