Herron preamps are very neutral. Not sure there will be enough warmth there for you. I used to own a Joule Electra LA-100 MkIII (I compared it in my system with my friends Herron) which I felt was incredibly musical with just the right touch of warmth for my system. I ran it with a solid state amp. The LA-100 is actually a tad more neutral than most preamps I have heard, but if you get a chance, check into one of these or the newest version of the LA-150.
