Need advice on preamps for Krell FPB, Elipsa

I have Sonus Faber Elipsa speakers driven by Krell FPB 250mc mono blocks (replaced my JC1s recently). The BAT 51SE preamp, although detailed, excellent in bass performance and fast, is slightly dark and cold to my taste. I listen to classical music most of the time (large orchestral, violin, piano etc) and some jazz and vocal. Is there a better sounding More musical preamp below $5000 (used) that would match my system well? Had some SS preamps but didn't like them. Don't like Audio Research either ref 3 either.
Thanks.
