Best speakers for around 30K?

Considering the best full range speaker in the $30000 range. Any suggestions, new or used?
Until now, I'm researching the following:
-YG Acoustics Anat Pro
-JBL Everest DD66000 or 67000
-Wilson Maxx 2 or 3
-Tannoy Kingdom Royale
-Focal Grande or Maestro Utopia

If natural, realistic presentation of music rather than a 'high-fi' spectacular is your goal, then you should consider SoundLab electrostatic panels. Check the "Planar" listings here on Audiogon.

Couple comments:

(1) I think the question s/b rephrased as.... " any suggestions as to what is the best speaker to BEST MATE with my source, electronics, cables, listening arena, and favourite listening genre?..." Can you elaborate on your supporting system?

(2) "Best" is a personal value judgement - one man's candy is another man's poison. There is no substitute for YOUR OWN in-person actual physical audition of the various speakers mated with your gear. Achieving that elusive Holy Grail synergy is both a lengthy process and a journey, cuz "one size does not fit all.". Soliciting a recommendations list based solely on a random price point by itself rarely -- if ever -- gets that synergy. There are many circumstances wherein a significant reduction in price for a speaker selected, actually sounded better in a particular system for these reasons. The point: Synergy matters.

Without phasing in the above, (regrettably), your query per se will likely generate heavily biased personal editorials (however noble) with an absence of any proper bespoke tailoring to your system. Good luck in your search.
Here is one speaker that you might consider. Below is a review of it. Less then the 30K when you look at the engineering you can understand that your money is going for something besides hype.

I fell in love with this company many years ago and brought the line on. They just keep improving. The Vector has tons of spacial qualities that so many speakers lack. The bass is very accurate and fast. The midrange driver is connected directly to your amplifiers so they will let you know how your upstream equipment is.

See if you have a dealer near you.
