I like Katans design because they are placing more emphasis on the box construction (tenon and mortise, larger bracing, 2 inch MDF in front and back) to ensure stiffer and stronger enclosure. The fact they use ceramic drivers helps but I like to look at some innovation instead of just placing ceramic, kevlar, or wood pulp drivers in a box.
Avalon and Ascendo also has unique emphasis on box construction.
