If the 3800 is on your short list, then it would be my pick. The 6800 is not $2,000 better unless you ned to do something like 7.1.6.Yeah it's insane value right now but since I don't have any external amps atm, I don't want to get a weaker amp section than I have right now in the 4400h even if it's only a minor downgrade. I will buy Dirac in any case since it's the main reason I want to upgrade my AVR.
At below $1,000, the 3800 is unbeatable.
