$10K-15K short list?

Well if you wanted to purchase some speakers that you would fall in love with, that are not made of cheap MDF, that don't have a soul sucking crossover, or notch filters, ( for the cabinet resonance ) that have the best signal to noise level of any cabinet speaker, that don't have fat flabby bass, that are fast and nimble, that image like crazy, that play loud and play soft, that are very engaging, that you can listen to long term without fatigue, that have a midrange the covers almost the entire midrange, the I would suggest the Wilson Beseech Vector.

The Sonus Faber and the B&W 800 Diamond series will also pair well with the McIntosh. "

I visited a friend's house this past weekend.  He was driving B&W 803 D3s with McIntosh pre and power amps.  He also spent a lot of time on his room setup.  I must say that they sounded great.  Such precision and definition.  A little bit lacking on the deepest organ notes, but otherwise a nice, clean, deep bass. 

There are so many good speakers in this price range, especially if also considering used.  It would take me months to sort through them.

Egglestonworks Andra II or III, Aerial Acoustics 20T, or Revel salons 1 or 2

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.
