You don't have to wait for the Rowland ICEpower. It's here, and it's spectacular (to paraphrase a Seinfeld episode). And there will be more powerful monoblocks out soon, if 250/500 wpc into 8/4 ohms is not enough for you.
Gryphon 2200 or wait for the new Rowland ice power
I have a pair of Piega p10's which are said to like high power/high current ss amps. I have a Belles 250i that sounds wonderful, but i feel i need more power due to room size and listening levels. I was considering a gryphon callisto 2200 or the new rowland ice power integrated soon to be released. Any experience with the piega's with either of these amps?
