Unfortunately the Denon on AC41 is out-of-stock. The Amazon site prices are still lower than my Yamaha idea and I like the aesthetics of the face plate better. But although I have no problem with factory rebuilt, I do worry about used. I don't want the dented one. The other caveat I have is lack of wifi in the unit. I'm not even sure what flexibility I would use by NOT having it. After all, these are new features to me. Option b: has some good features like the wifi, but doesn't look as good as the Denon and I wonder whether it is beefy enough for me. (I guess I don't trust a $399 receiver). But you gave me much to think about. Thank you.
