(Holds head in shame - never thought I would post a "which receiver" thread)
It happens to almost all of us. So easy to blurt out advice, spend other people's money, but it gets tougher when you have to choose for yourself sometimes.
If all else is the same, I'd go with Denon because I'd want the Audyssey suite. That one has vanilla multEQ, Dyn vol, and Dyn EQ. If I buy one soon, this year, it will have the XT version of the multEQ as well DSX so I have the chance to add height speakers.
If you don't care for the Audyssey suite, go with the better price I guess.
