~$15K floorstanders: opinions sought

There a chance I'll be able to make a significant investment in my speakers within a few months, and jump from $4K/pr Focal 926 to something in the 10-15K range. I'm running krell gear and have no intention of changing electronics, they are perfectly suited to my ears - - but if new speakers expose weaknesses, then I'll tackle that later.

Here's the thing: aesthetics matter to me, a lot, and I'm not ashamed to admit it. I love my art and home and music is a huge part of my lifetime joy. These are some of the brands /models that I personally think are beautiful, and I'd love to hear from folks who could speak to a possible pairing with Krell. I like precision, speed, clarity, and firm bottom. 

Room is approx 18x20x9. New or used is ok.

Von Schweikert Endeavor SE
Vienna Acoustics Klimt The Music
Magico S3
JBL Synthesis (4700, 9900, etc.) 
Spatial (loved the demos I heard but not sure if OB would work in my space)

Appreciate any insight, despite the aesthetic emphasis. 
Wassaicwill, any decision yet?
Hi dramatictenor, I'm leaning toward SF Olympica, Focal Sopra 2, Rockport or Von Schweikert. The SF and Rockport weren't really on my radar before I put out this call for help but I'm impressed by what I'm learning about both. I've heard the Sopra so I'm hoping to audition a few more brands in the days and weeks ahead. I typically move very slowly and then very quickly once I hear "It" that I'm looking for. I'm overwhelmed by the generosity of the folks here and so very grateful. 

You can consider used Lansche 4.1

I had lived with the speaker since 2007, but I have nothing to do with linked listing.

It gives the pristine treble out of plasma tweeter.

Eva Cassiidy’s voice sound spooky.

With two active 10 inch drivers, it can go down to 20 hz.

It also looks gorgeous with excellent finish.

Nice WAF.

If you live in California, you may ask the seller to audition it.

I may let you listen to my speaker if you are in Pacific Northwest.

Thomas, thank you. I'm fascinated by the plasma tweeter concept and would love to hear them.
