I've only had my ICBM for about a week now with only a few hours on it.It is in between my preamp and amp{a 2 channel system} feeding a HSU VTF-2 sub.This unit seems to find bass that I didn't know was there.The bass just seems more powerful.I had been looking and reading about it for about a year before I bought it,now I wish I had got it long before I did.Good job Outlaws.
