I've been pleased with my old Paradigm Atoms (purchased a Salvation Army for $7.50!) driven by the Icon 1. There is a slight hiss, and the amp isn't powerful enough to go as loud as I'd like. I have to turn to the volume knob to 12 o'clock before I can even hear anything. I have just ordered the Icon 2 upgrade, which has 50% more power, so hopefully that will be enough.
Otherwise, I am very impressed by the definition and overall presentation of my system, which is augmented with an M&K V-75 Mk II sub to nicely fill out the bottom end.
