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.

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.
