Nobody has answered your question, Say811, so I'll give it a try. I have listened to all of these speakers and each is VERY different from the other. The VR-4's, as you may know use a rear-firing dipolar tweeter. The model "VR" stands for "virtual reality". If you enjoy a more ambient sound and a larger sweet spot, then you might like the Von Schweikert's. In addition, they have TREMENDOUS bass response, probably the deepest if not tightest (for lack of a better term) of the three. Vandersteen and Thiel are at the opposite ends of the spectrum in terms of their overall sound. Many people consider Vandersteens to be somewhat "dark" in their presentation while others find the Thiel to be too "bright" or "forward". In any case, the Thiels are more analytical and will probably be more revealing of any weaknesses in your system. Meanwhile the Vandersteens are a bit more forgiving of system shortcomings as well as poorly recorded music. Although your musical tastes are quite varied, most of the artists who you reference produce(d) relatively decent sounding recordings, so this might not be as critical. I will say, however, that there's something to be said for a speaker that gets out of the way and just lets you enjoy the music, and in this regard I would have to give the nod to the Vandersteen 3A. I don't own any of these speakers, but I recently bought a pair of Hales Response 2's here on the Audiogon. The Hales follow a very similar design philosphy as the Thiels and also have a similar sonic character. While I LOVE them for the things that they do well (female vocals and piano in particular), I find myself listening to less of my music collection and have actually begun to purchase music that I know will sound good with the Hales'. I don't think that you could possibly go wrong with any of these choices. By the way, in your original post, you asked whether you should bi-amp or bridge your Citation amp. I would strongly recommend bi-amping. I sometimes wish that I had purchased that same amp and kept my speakers (Platinum Audio Solo). It's an incredible amp for the money! Best of luck to you.
