My recommendation...
Which receiver can you get your hands on and return if you aren't satisfied? I swear, these receivers are all so close, you can freakin' go mad quibbling over the minute differenceswhile paper shopping.
Zero in on the receiver your gut tells you to go with. Take it home with the expectations of keeping it. Hook it up and see how it sounds then run it though the gauntlet.
I was stressing over this and that, almost paralyzing myself into no decision. Then I looked at the Denon 3808. It hit me like a bonk over the head. I was looking at the 4306 and 4308, Pionner Vsx 94 and 84, Yamaha 2700, etc.... Once I saw the 3808, I immediately bought it and brought it home. I have been grinning ear to ear since. If I got it home and it didn't 1. sound spectacular and 2. work without hitches then it was going back.
In my house with my speakers (Klipsch Ref Rf 82 mains, RC 52 center and RS 42 surrounds, Martin Logan Abyss Sub) this Denon thing is da bomb...and works flawlessly. I even hooked up a wireless gaming adapter to it and have it connected to Internet Radio and my home network.
