Thanks for all the excellent advice. Before I purchase the 80's (or 60's) I will definitely try to demo them in either NYC or Maryland, which should give me a better idea of which will work best. Both space and my girlfriend are the major constraints...

Also some good food for thought on the 606. I suppose in the wost case scenario I just trade out the 80's for 60's (and then buy the 80's to compliment the 60's when I get a larger space!... and a new receiver to play with as well, haha). All good stuff.

Again, thanks, and I look forward to stalking the forums in the coming months!
