I have went back and forth. Quite honestly I am not settled with that one yet. The Onkyo models (newer) have the HQV Vida 1900 chip which is the best in an AVR I have seen to date. In all fairness to the Oppo it could get a newer firmware that might push it even further. When I had the Edge and or a Duo the Onkyo's processing was better. It is the main reason why I have stuck with Onkyo the past couple years. I would love to experiment with the new Denon 4520 soon but I suspect the video processing might be the same as the 4311 and the Onkyo is better hands down. Of course I could send 1080i or 720p thru both and let the 1000 upscale. Hmmmm we have too many options these days.
I will experiment during tomorrow's game and post back.
