I'm running the RX-V1400 on my M60's and I'm very happy with it. Before the Yammy; I had the Denon 1601 and it sounded good but not as good as the RX-V1400. I know its the bottom end of Denon lineup so comparing it isn't fair. Some say the RX-V1400 makes the M60s brighter but I didn't find it that way. I think its all about setting it up right.

People here rave about the 3803 and 3805; so either way I think you wont be disapointed.
