TAD Reference loudspeakers-How good are they?

Just wondering if the TAD Ref 1 and/or TAD Compact Ref 1 are as good as some of the show reviews suggest, although a recent review did mention a slightly "dark" presentation, albeit state of the art sound.

Does anyone know if the implementation of concentric tweeter/mid is superior to that of KEF/Thiel, or perhaps the Berylium constructed drivers and/or crossover sophistication.

I'm thinking about the TAD Compact Ref One as my "final" loudspeaker, as I have a small listening room at 14 x 16; Quite expensive at MSRP of $37K. I would appreciate any and all opinions and experience with the TAD Reference loudspeakers.

Thanks so much!
