Very nice system, congrats to you. I too, fell in love with Wilson Benesch, though when I heard them at RMAF '07, with the DeHavilland amps and preamp, the smaller stand-mounts were in use.
Actually, I've been lusting after DeHavilland gear ever since, but they have always been a bit beyond what what I could afford. The WB Curves must be outstanding as good as the smaller WB's are.
Regards, and enjoy,
