Yes, the Vandy 3a sigs go for $2K used(that's what I sold mine for), but they take up more room than the Thiel's due to the Sound Anchors(Which is why I went to the Treo's).
Both Vandy and Thiel based their speakers on Time and Phase alignment, so I would think they should share similar characteristics.- Which is why I'd like to hear a pair. I don't think I would be disappointed with the models designed by Mr. Thiel. He certainly garnered a loyal following.
Vandersteen speakers play music. It doesn't matter what you are listening to. I was hooked 30+ years ago when they first came out. I was glad to find they have prospered during my stereo-less days.
A quick look at Vandersteen's website shows a dealer near Milwaukee:

John Rutan at audioconnection (his Agon name) gives great advice and can help you with making decisions. He has tons of experience with many different manufacturers.
