I'm late to the party and don't have much to add, but since I just got my 60's and they're about 9-10 feet away from me, I thought I'd chime in.

They sound beautiful. I haven't watched a movie with them yet - this weekend. But the music is awesome. The soundstage is so much larger than it was before (which it should be given what I had).

Anyway, no worries with that distance.

My M60's make me listen
My M80's make my ears hear
Either way - I'm not deaf anymore
