~$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.

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. 
Thomas, thank you. I'm fascinated by the plasma tweeter concept and would love to hear them. 
I listened to a speaker with as plasma tweeter and walked away thinking, just because something can be done doesn't mean it should be done. That was a few years ago and they might be improved now.

In no specific order and obviously at this price component matching with the passive models will determine results
You do not mention anything about the type of sound you are looking for.  Like filed coil speaker sound, open baffle, horns, etc.  it comes down to preference not ours.  If you are more specific on your experiences and what you like then there is a starting point.  DynamiKKs are German made speakers that to me have a horn sound, details/clarity, deep bass, very open and airy, easy to drive, the company makes their own drivers.

Happy Listening.
