I don't have the bp10, but I have heard them. I also have the deftech 1000s, and the sm65, and the kef q300. In my opinion the kef mids are much stronger and cleaner than the deftech mids, and the uni q creates much more depth and imaging. Also, the clears on the kefs are much more 3 dimensional and airy, while the deftechs sound very one dimensional or thin.
