$2000.00 to spend on new speakers.

I recently heard a pair of Dali speakers that were in the $2k range that were impressive. The hersey’s have been in the klipsch lineup forever, congrats.

Your selection of gear shows a lot of good choices you have made.
I like horns and larger woofers but for some reason the Heresy 
never sounded quite right to me. The good news is that they are one of the most popular speakers so resale is easy. 

I see some good and some horrible suggestions above.

Good luck!!

I like the material of their cones.

Here's an interesting video that shows how the shape of cones can be distorted. I can only imagine what might happen to the sound.
