$10K-15K short list?

Alot of good choices.
I would recommend Legacy Signature which i heard at a NY HI Fi show in 2014 which were great.   Here's a video of the Legacy Signature speakers.  https://www.youtube.com/watch?v=3XrMtzzNHds
I also really like JM Lab Mezzo Utopia speakers and JM Lab 920.1 speakers from the 2000s. 

I would certainly recommend going to the RMAF this fall. Money well spent. I remember going to the CES show 2004 and 2005 going into so many rooms that reviewers had raved about. Most I would just do a U turn. I don't need to eat the whole egg to know it is rotten.

Wilson Sophia 3 or Sasha 1 are in your budget used...  I have Sophia 2 and love them. A friend has Sasha 2, and they are incredible.

@dhanks   I'd narrow your list down on your own before opening it up to feedback and specifics on say two or three speakers. 

There have been many good recommendations given, but for me, this would be an overwhelming exercise due to an overabundance of choice.

As @ricred1  brought up a few times, your room is critical.

What you listen to and how you listen is important as well.

Are you open to changing your amplification? If you want to try something different, then that should dictate your speaker direction.
