There would still be many to choose from, so do you have a budget?
If used is an option, Joseph Audio RM7 or various Proac or Reference 3a monitors all excel at what you’re looking for. There’s also a pair of Silverline SR17s available here now below your price range you should seriously look at, or their Minuet monitors if you’re looking new. You should post your electronics as well as that could help further focus recommendations. Also, what are your current tower speakers? Best of luck.
If you are looking for great midrange, it is hard to do better than ATC.
We have the SCM 11 good, and the SCM 19 better and the are fantastic.
Huge sound stage, natural and uncolored midrange, good top end detail and great dynamics.
The ATC line is very balanced and musical, without being bright or rolled off. They like power however, we have driven them with as little as 40 watts
It will also come down to wether you prefer a more detailed sound Focal, KEF, B&W, Paradigm or the wamer more laid back sound, Harbeth, etc.
If you like neutral to a little warm try to listen to Dali, or the ATC.

My current speakers are Legacy Classic, with Primaluna Prologue Premium power amp. For pre amp I'm using the Aric Audio Unlimited. Sources are an Onkyo CD-7030, a modified Sherwood S-3000 tuner and a modified Yamaha YP-211 turntable. Cables vary as I have a large collection of cables both in silver and copper. I listen to Jazz mostly but tune in to contemporary radio stations on a regular basis.
Your Primaluna amp and Aric Audio Unlimited pre (I own one too) are quite midrange heavy to begin with. Depending on the types of music you listen, a midrange heavy speaker could make the overall tone too unbalanced. If it were me, I'd look for something that is generally balanced. My personal favorite is Dynaudio X14 and it should fit in your budget if you can find one used. Good luck.
Well, after a trip to Montreal and auditioning a pair of speaker I thought I'll like I realized I wasn't going to get much on trade in for my Classic. It just happen that the local Craigslist had a pair of Platinum Audio Solo for sale. I offered my Classic in trade and he accepted. The Solos are as good as the reviews describe them. I'm very happy with my new speakers.
