axiom_man,
I hate to say this, but you have a reached a point in audio where if you want more, you have to pay a hell of a lot more.
The higher end Denon's sound as good anything out there, and have a lot of power. If you want something that will blow it away, get ready to spend well over $5k.
Let's say you buy some Krell equipment and blow $20k on it. If you did an A/B test with the Denon 3803 at your regular listening levels... The difference may or may not be there, but it certainly wouldn't justify $20k (unless you're rich and that's chump change for you).
What exactly are you looking for? What doesn't the Denon do that you wish it did?
