Marantz 7400 vs Denon 3803

You probably won't hear a dramatic difference between these two. The Marantz is a really a Pioneer with the audio stages tweeked for better sound. The Denon's have always been among the best receivers. Using in-ceiling speakers will be your weakest link anyway. Pick the receiver you feel the most comfortable with. Check out the controls and the remote, and pick the one that you like to use.

Thank you. just picked up the Denon today, and still have the Marantz NIB.

Yep, Steuspeed hit it on the head
