I am surprised that you mentioned enjoying the KEF 104 and have not looked at their modern version the 207.2.
I have these speakers and when properly setup are about as good a speaker that you can purchase.
The KEF's have an absolutely stunning mid-range, fast and well defined deep bass, the speakers are remarkably transparent, the sound-stage is incredibly wide the speakers totally disappear. The Kef's have outstanding resolution an can play very loudly as well.
Personally I would take these speakers over the Sasha, the Magico, and the Sonus Fabers. The Ushers are very good they are not quite as coherent as the Kef's nor will play as loudly. If you are in my area I would love to have you over for a listen!
