Hello Ctsooner. Thanks for the info on Audioconnection. I live in Wisconsin, hence my lack of knowledge where Audioconnection is. I never was a Vandersteen enthusiast before, but have listened to their latest speakers recently at several dealerships and came away impressed. I pulled the trigger and purchased a pair of Treos with the carbon tweeter. They replace a pair of B&W 802D's. I have to wait awhile for them because as they are being made, I also have to wait for the Vandersteens to come back from vacation to finish my pair. Can't wait. A salesman at my dealer said he has a pair of Treo Ct's, along with a pair of the Vandersteen subs. He said, in his opinion, that this combo out performed the Quatro Ct Wood. Can't personally verify this as I haven't listened to that combination. But this was his opinion. I do agree that the carbon tweeter is a large step up from the standard ceramic tweet for the same reasons you expressed. All in all, good design.
