Worth the $700 price difference, in anyone's educated opinion?

I finally found a spec list for the 4306 other than on Crutchfield! Denon, to my knowledge, still has not listed the 4306 specs on their site.

Unfortunately... Crutchfield just moved the ship date on the 4306 from 11/11 to 12/1. Boooooooooooooooooo.

Appreciate any and all comments, even if you say something like "Why not buy the xxx model from ZZZ?" I seem to have gravitated to the Denons due to the HDMI switching. Not sure I really need three inputs, two might be enough (cable box and dvd player)...

Links to specs:
Denon AVR-3806
Denon AVR-4306

Appreciate any and all responses. I have my tv already, but I have to make up my mind what to buy on the audio side!!! Prob. going with Axioms, that's why I'm here. :-)

Thanks! -Al
