I just put in Thiel CS 3.7 in a slightly larger room than yours. I removed a closet door to give me a bit more space, especially the space from my head to the wall behind me. I am assuming your space is a dedicated listening space.

1) If you can do anything with this room them get some GIK Acoustic treatments (or from anybody else). GIK will work with you remotely to find the best products to use for your room. My stuff was the lowest priced ones and the 9 panels totaled $700. They make an incredible difference. That floor stander in my room sounds great after the panels were added. I am shocked that my floor stander works so well in this room.
2) I am going to explore adding Digital Room Correction next after I get my speaker repaired (figure that out tonight). With DRC I would not even need the panels but they are supposed to make the DRC easier to implement in the treated room. I use ROON for my streaming digital and the DRC will be implemented as Convolution file(s). Not too expensive to get a professional sound engineer to implement this remotely. PM me if you want more details. I am in the process of doing this, though I hit a road block with a speaker driver problem that will get solved soon.
3) If you have separates why not go for a Class AB amp such the CODA #8, Bryston 4B3, Parasound JC5, Hegel 390 integrated. These are not that expensive and run cool. I will be running 2 Benchmark AHB2 which I am not sure would work with your speakers. PM me if you want to talk about the AHB2, I did a lot of research on this amp into low impedances.
4) The KEF LS50 META maybe something you would like. It is a perfect fit for your room size. I replaced my KEF LS50's with the Thiel CS3.7 but the LS50's worked great in my treated room. Prior to treatment not so great.
Big speakers in a small room. Been there, done that, got it to work great.
