$20k top, full range speakers?

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!

What I point out to people is that Kef has spent an incredible amount of time and money to develop the technology of the their speakers. The Uni Q is in its 10th generation.

My point it with the .2 versions Kef has made one of the most perfect coincidental loudspeakers, a true point source. The lack of smearing, and heroic cabinet build: birch cabinet, extensively braced with the midrange/tweeter housed in an truly inert aluminium enclosure, means that this speaker has great low level resolution, I loved the old Kef models in their day, but for many people Kef's designs were eclipsed by other companies.

Kef recognized their market slip and has been on a mission to reinvent their image and products, I started looking into Kef after Stereophile's review of the 207.2.
