The PMA2000 is a truly special amp, does many things right. Not much of a fan of the 1500 or the 500, the 700 is not too bad. Overall I find the denon amps have a very warm sound signature, and perform best when cranked hard. Not the best at detail retrieval, but a pretty smooth 'listen-all-day' kind of sound.
+1 to that cranky.have heard the setup of a close friend who runs a marantz cdp(forget model no,damn!) with a denon pma2000 through jamo d590 speakers.was my first real listen to great equipment.stunning to say the least.cheers
