I'm kind of with Ken here. I don't think you need to spend that kind of money to get excellent results.
I know you'll be very happy with the Epic Grand Master 500 system. Are you getting a stock finish or a custom finish? If you are getting a stock finish and have the room, for your budget I'd spend more on the speakers (i.e. get Epic 60 or Epic 80) and less on the receiver.
That being said, nobody has ever been disappointed with a Denon and I'm sure any of the models you mention would be quite lovely. Perhaps budget for a good universal remote control.
