Advice from Audiogon family - best speaker $3k-$4k

Don't forget about Vandersteen. The new model 2 Ce Sig. III is right in the middle of your price range. If you dont mind the looks of the model 2, it would be a good choice. Not bright and very detailed but not overly analytical. 

Klipsch Forte?

+1 Focal used Kanta 2 possibly in your budget. Good luck ! 

I am in a fairly similar search mode as the OP, and would have seconded @vinylzone suggestion of Maggie 1.7i at <$3k … BUT you can’t drive them adequately with that Mac integrated, and small/medium Maggies are so dependent on listener room constraints and preferences for genre/content (eg lower extension/dynamics)

In that price range +1 on the Sierra towers with raal recommendation. Had a pair for 8 years, great imaging and depth, wide soundstage, very airy and detailed with yet excellent bass.
