I have recently bought the Monitor 70's, CS2, and monitor 30's. I would like to know what amp will have clean crisp sound for all speakers. I would like both detailed sound, as well as dramatic for large action sequences in movies. I would preferebly like a seperate 5ch amp from the receiver. Also i Have read that the newer D-class amps use less power and produce just as much juice, without sacrificing sound quality. Any and all suggestions are appreciated.
