What's Next

Vandersteen ,at your budget try 5A or model seven used

I’d suggest a lengthy listen to some Focal Utopias - now the Evo range is out there will be some great buys on Scala V2 and Maestro.
Magico Q3 if you like resolution, S3/5 is you want more full.
KEF Reference are a little rolled off, Blades marginally better.
Tidal, Lumen White, Kharma and others with the Accuton ceramic drivers might appeal?
You might find Raidho the sweet spot...

Beautiful system.
Good fortune in your ongoing quest! 👍

This veteran audiophile thinks you should look into the Wilson Yvette at 26k list.
I don’t know what bias you may or may not have for Wilson but the Yvette is a beautiful sounding speaker with plenty of mojo should you want it. It also their best looking speaker in my humble opinion.
I’m not even what you might call a Wilson guy but in a world of overpriced gear at least Wilson gets everything built to an incredible standard including the wood crates. As is well known the drivers are not exotic which bugs some people.. The main thing is the sound and it’s awesome. I’m spending way too much time listening these days.

ricred1, nice system and room.  You make me want to get out my vacuum cleaner!  Sounds like you have decided on a speaker change, perhaps the biggest decision with a system. 

You are right about cables, the combo's and synergy possibilities are endless.  However, I would echo Keithtexas that MIT's would be a big change.  Not only his recomendations, but the newer 2C3D line and EVO line in the Heritage series offers some serious trickle down performance for more reasonable pricing.  Good luck and it will be interesting to follow your journey for me since I own Thiels and that brand is cooked!
