Help me spend $6000

I’m looking to get the best bang for the dollar. My amp is the Pass Labs INT-25. I listen to a lot of jazz,folk,classic rock,and funk. 
Floor-stander or monitor is fine. Prefer new, but I’m open to used. I’m looking for a detailed presentation, but not bright. I also prefer a thick midrange. 

Room is a bonus room with knee walls with carpet and bookshelves everywhere, but not officially treated. I sit near field.
