have you heard the CR67's? they stand quite appart from the rest of the bostons ive heard. In fact I dont fancy any other boston speaker really, other than the larger VR-3s which are nice but dont sound quite as good for music.
Also when I say held their own, I dont mean litterally, but there were definately some big similarities, the bostons having a more forward sound in the upper midrange and treble, not as pinpoint imaging, resolution and detail was almost identical though, as was upper bass definition and dynamics at low / med low volumes. Scale was obviously larger and the piano's definately had more body. but in terms of disappearing into the room and providing a wall of live presentation sound, the bostons did admirably. The dealer carried(Sonus Faber,B&W,REL,Monitor Audio ...and more no boston products though. throughout the A/b He said quote: "they are phenomenal little speakers".
I was there to audition the REL subs, with the bostons though mainly.
