2 Channel H in the new guitar player mag
The November Guitar Player, with Alex Lifeson on the cover, has a roundup of 11 half stacks. The PRS gets an editors pick (along with the Peavey Triple XXX II, the Mesa Royal/Atlantic, and the Egnator Armageddon). The amp had "a great range of clean to highly overdriven tones."
I was impressed with the sound of that amp in the "laying down the lead" sessions at EXP 2012, though I wish I had jumped on one of the 20 watt models a couple dealers had over the last year or so.
