Good Speaker within a budget of USD10,000

I recently asked the same question and demoed many speakers and bought a pair of Revel salon2's used for a bit over $10k, BUT my room is 18x26x7 and it absorbs bass. I had several other favorites for a smaller room.
Focal Kanta2 $10k
Dynaudio Contour 30 $6k
Revel f206 $3500?
Kef r700
Vienna Acoustics Beethoven!!!!!!
It's less of a crapshoot putting a system together now compared to 25 years ago but manufacturers still have their own idea of what makes a 'better' product and matching components still matters.

When I went shopping for speakers with $10,000 I got some salon2’s and usher be20dmd’s and for my Hegel h360 the ushers were better, although I think the salons may have a higher ceiling if I could have matched them with a $$$$ amp. There was a pair of sopra 3’s for sale for the longest time for $10k I nearly bought just because of the price! 

The problem for me is after I spend $10k on speakers I got nothing left to match components. Many companies getting into active speakers and the ones ive heard sound better than the passive version.

Listening to The Black keys ‘turn blue’ on a pair of meridian dsp 8000’s I got used for around $10k and I haven’t heard better for the same money.
