Jserv,

I have a pair of M22, contrary to the belief of many people here, there is a difference in sound btwn different receivers when I pair it up with my M22. I have try both the Denon AVR3803 and Harman Kardon AVR320. I have to admit even though I don't want to, the M22 in my opinion sounds better with the Harman Kardon for music. Now you can say I like the Harman Kardon better because it is warmer or whatever, but the fact is different receivers do sound differently.
