I want a warmer high end

Also a previous Paradigm Studio 60 v.2 owner. They were too bright for me, irritating really. I never really tried some of the advice mentioned above so it may work for you.
As for speaker recommendations, I'll give you the three models I found to be the best in your price range. First on my list is the Soliloquy 5.0 monitors, these are extremely fine speakers at the used prices. The main problem with them is the company is long out of business. Next on the list is the Quad 12L2. These are very good for $500. Very smooth sound and if you like a glossy finish, they have a superb one. Lastly, I like the Polk Audio LSi7. I bought a refurbished pair from Polk on ebay for less than $300; absolutely perfect condition. Good luck with your search.

If these are metal dome tweeters,that may be the problem. Paradigm has had a lot of different sounding speakers through the years.

Try Spendor or Dynaudio.

Jdombrow has a good idea - try Cardas ICs - the best (used) in the line you can afford. (Disclaimer - I have a pair for sale.)

Have you experimented with "footers" under your components that can tame the forwardness and the high end?

I've done a lot of system tuning and every footer alters the sound differently.

In your case 30 Durometer Sorbothane hemispheres or Herbie's "Tenderfeet" might be just the ticket. It is shocking at times what good system tuning can do to change the sound of your system. "Softer" materials like the two listed above, in conjunction with mass loading your components would almost surely get you much closer to the sound you desire.

The best news is that all of this is inexpensive!
