KEF Concept Blade

I profiled the KEF Concept Blade speaker here, but since there's only one pair in the world, there was no way for me to hear it until the company brought it to CES and set it up in a room at the Hilton with an Audio Research CD5 CD player and DSi200 integrated amp. Listening to Patricia Barber in a live recording and a tenor sax with rhythm section, it sounded quite good overall, with very clean, tight low bass, but the upper bass and vocal range was slightly congested. The KEF rep agreed and said it was the room, and I couldn't disagree—hotel rooms generally make lousy listening environments.
