HI Huntermusic,
Is your upgrade limited to consideration of the preamp? Also, what is your budget?
If you are only looking at the preamp (and I am assuming you only need a line stage), some options you may want to consider in the ~$20-25k price range include the SmC VRE-1C, the Doshi Alaap 3.0, and the Constellation Virgo II. For a little on the higher end, the the Ypsilon PST-100 Mk.II may also be worth your consideration.
However, I think you would be better served looking at your speakers, and to a lesser extent, your amp. I think you will get a much bigger bang for your upgrade dollar, and will be able to address the "hardness" that you identified.
