Anyone have the chance to listen to the Boston Acoustics VR series speakers.I'm interested in the VRB bookshelves.No dealers have them in my area.Would like to know how they would compare to the Paradigm Studio 20's or BMW 600 series if anyone knows.They appear to be a mid line speaker in between Boston's lower CR series and thier top line VRM.I was quite impressed last year when i listened to one of Boston Acoustics VRM floorstand speakers.That was at Tweeter and now thier out of business.Thanks in advance.
