Do you mean the 4806CI? Or are you buying a refurbed 4806?
I'm not sure I'd go for the refurb. I believe it has issues with 7.1 LPCM. I was keeping up with this unit and firmware updated because I wanted one. I stopped researching it a while back. I don't know if Denon has issued a firmware update to resolve these issues or not.
If I were to buy a new AVR today, knowing what I know, I'd get the Anthem, AMV-40 because I use an external VP. Not sure what I'd use for amplification, but the Emotiva's look OK for the money. If I needed a so-so VP with the AVR, I'd go for the 4806CI over the 4306. It has more to offer than just a video processing piece and THX. They dumped some coin in it's DA's and other gadgets for improved sound quality.
Marnantz is working on their 7.1 LPCM bugs (I'm one of their test dummies and they are forwarding my findings to Japan for resolution). It has its problems just like the rest of them, but damn it sounds great....
