Lightning quick DYNAMIC amp in the under $1000 range

The only one I can think of off the bat that might be good to try is the Schiit Vidar for $700.

Right now I am using a behringer EP 2500, which is a pro amp, so wondering if I could add more musicality to my system with a "Hi-fi" amp

What speakers ?, the rest of the system ?, your room ?, your musical tastes ?, and do you play louder at times ? If you want " musical ", you will likely get recommendations on getting a tube preamp, if you currently do not use one. Enjoy ! MrD.

Agree that it would be very helpful to know a lot more detail...but generally speaking, you will get a lot more bank for the buck buying a preowned....there is almost always good stuff available as new stuff is coming out all the time that people want to try.
