I'll chime in on the PSB B15s as well; I think I paid $369/pair. I'm a newbie, so I can't speak to the type of music they're best at. I tested them with Roy Orbison and Emerson, Lake, & Palmer, and they filled up a small room (~12'x14') just fine. I use them as rears, with T45s as fronts, but I believe the B15s could stand on their own on a 2 channel system in a small-medium room. I also believe I am wasting their potential using them the way I am.
