hey, you said in another post to stay away from sony xplod amps? why? i have been considering a sony XM-752EQX to drive a single Polk Audio DX10. the amp looks like a great value (not from circuit city) at $150. it has all the features i've been looking for at least. what is your complaint about sony amps or waht problems have you seen as an audio store employee? thanks for the help!
