I have a pair of GP's and origionally used a 1080 rotel.....it was ok, I went to a classe ca 101, and was floored by the detail the speakers could play......liked one classe ca 101 so much that I got a second, and ran teh gp's off of mono amp configs, and they are AMAZING!!!!!! got a good source component, and have decided to no longer use my sub, they dont need it. Give them plenty of clean power, and they really come to life
