Talon Firebirds, Aerial Acoustics Model 20T, VR-7

Has anyone any sense as to how these three compare?

The Von Schweikert VR 7 receives considerably less talk in these forums compared to the unrealistic V-11's and very expensive V-9's. In the $30K price range there are many really great choices including the Wilson WP7's. Since other than going to the shows, doing any A-B comparisons is virually impossible and makes this a frustrating choice when memory alone is my guide. Not to mention a variable mix of front end electronics, ss amps, tube amps, ± preamps etc.
