I just swapped out the amp I am using to drive a pair of Paradigm Studio 20 v2. in the surround back channels of my HT. I was using a Paraound Zamp v3, great amp, no trouble driving the speakers in this application. The PW Amp has ARC so I ran ARC before I ran the Audyssey in my Marantz processor. Prior to running ARC the Audyssey set the crossover at 80. After running ARC it set the crossover at 40! ARC does such an amazing job. I have used this amp in my desktop rig too and would recommend it highly. Right now the PW line up is on sale and the PW Amp is 50% off.
