I've heard a few of the Boston VR series speakers (though not specifically the VR3) and they can't compare. The upper bass/lower mids are REALLY muddy, and the their low end tended to be a bit boomy. Certainly not the charactaristics you're going to want in a speaker.

The M60/M80's are clean and tight from top to bottom.

How big is your room? How far away will you be sitting? How far apart will the speakers be from eachother/side walls/rear wall?
