Paradigm studio 80's to harsh, Parasound HCA-3500


I have Paradigm studio 80's v2 with a Parasound HCA-3500. I think this setup is too harsh and I am looking for ways to correct this problem.(possibly a different amp or if anyone knows of a preamp that would smooth out the highs.) Also, I am thinking about getting a Proceed HPA-2 and am wondering how it would match with the paradigms?

I have the Studio 100v2 with Sonic Frontiers pre and Anthem MCA-20 amp. I'm using Virtual Dynamics Audition cables all the way through and the highs sound great. In fact they sounded a bit muted when I was in my apartment because the room was overdamped. You may wish to play with room treatments although your amp may be to bright for you speakers or vice versa.
I agree with Thomas above. I owned Studio 100's v1 and v2's. I switched to a Black Gate moded PS Audio HCA-2 and I thought I had found sonic satisfaction. No fatigue, plenty of power, well defined bass. I borrowed a pair of Avalon Acents for a few months and I couldn't get rid of the Paradigms fast enough.
