It's too bad there are so few Tannoy Prestige dealers in the US. I picked up my Kensington SE speakers from Audio Atlanta in Marietta, GA (got their floor model). Find a way to get your ears on them - it's been most musically rewarding purchase I've yet made in this hobby. Hardly anybody in the US has heard them, it seems.
I've also heard from people I trust that the Glenair (the big 15" one, not the 10" version) and Churchill Wideband are stunning. Must admit though, I'm fond of the Kensington's styling.
