I have a pair of T-7's which just received the newly available "Chapman" T-7 upgrade. New Chapman propriatary woofers, Scanspeak mids drivers, and the quantum leap newer totally upgraded crossover components and internal wiring plus Black Diamond racing cone feet and binding posts. Like an electrostat but with the transient dynamics of cone drivers. A T-7 with the "Chapman" upgrades for ~ $2000 is one of those rare audio treasures. Just be sure to give them time to breakin and you will be amazed.
