It is not so much that I can do better than the Aerials, but it is simply a matter of space, and I might need to move my system into an area where monitors, or smaller floorstanders, would be more appropriate. At this point in my life I have yet to acquire a space to call my own, where cables everywhere, and 100+lb speakers do not matter to an interior design minded wife. Right now I have a great sounding system, but there is this nusance complaining in the background that I can't seem to make go away... :-)
I have never heard the Von Schweikert line. They look to be nice, well-made speakers. And I have heard great things about BAT of course!
