Superdoof, you have a very nice system. I have always heard great comments on the Aerial line, but have never had the opportunity to hear them in person. I was just wondering what would be even better than the Aerials to make you want to switch!
As for suggestions, as you can see, I own Von Schweikert VR4-jr's, that I am very happy with. I have owned Martin Logans and B&W's also. I use a tubed-pre and solid state BAT combo.
Good luck in your speaker search.
