What made you choose that receiver? Are you going to use multiroom? Do you really need the 11.3 spec?
If not you will be better off choosing something else. I would be looking at spending half of the budget of that Denon 4810 on a stereo amp, and get an AV receiver with the other half... If you must have a one box solution, I suggest looking at something like a Yam Z11 or Z7.
