I got the Icon AMP in yesterday (thanks nuforce Help Desk team)! This is so strange, I didn't think this amp would make such a difference in my sound. I'm still not sure if it's the placebo effect, but everything sounds far brighter than it did!
I'll have to play around with it some more today, as I only got about an hour with it last night.
There is an audible *pop* within the unit a second after I turn it off, but I read this goes away after awhile, am I correct?
