I don't have any direct experience with either of the two receivers but can make a couple of comments :

1. Both of them are very good in terms of all the attributes you listed -- clean, quiet, high quality sound.

2. I don't remember seeing posts from anyone running M80s with a Yamaha but there do seem to be some posts indicating that NADs are OK with the 4 ohm load.

Since you are running M80s I would lean to the NAD... and to the extent that you believe one receiver is "better for music" than another the gossip tends to slightly favour the NAD for music. I don't believe that last point personally (ie I expect the Yamaha and NAD would be pretty much indistinguishable) but none of us know for sure.
