My name is Allen, I also have a set of Centurion speakers. I run them with a Denon receiver (till I save more $$ to step up) and I have tons of output. When friends bring over their high end amps, yes, they get louder and more detailed. In fact these speakers are louder than the last few sets of speakers I have had: Whatmough and PSB.
I have enjoyed these Centurions so much I bought the Roman Audio Pro Console center channel, the Senator's for rear fill, and the 12" powered subwoofer.
