Thanks guys,
Man, I would really love to get the Denon, but just dont have the Benjamins right now, in fact I already went way over budget getting the M80's.

I think I will tough it out, and if necessary break out the NAD.
It would be great if I can try it out and still have the option of returning the AVR, but not sure what the typical delivery time for the M80's would be, and need to check the return policy a Tweeters for the AVR.

Silly question, if I do decide to use the NAD as a pre-AMP to the Yamaha AVR, will the volume control still be based on the AVR or the NAD?
