The 7700 series is also worth taking a look at. I went from an AV8801 to the AV7704 when I got my 4K TV and there was no noticeable difference in sound quality or picture quality and the AV7704 has all the connections I need.
If you're open to refurbished, I'd recommend taking a look at accessories4less. You can get either the 7705 or 8805 with a 3 year warranty for way below retail price for a new one.
