Mikeaudio, I know that based on your thread you are looking for a SS preamp rather a tube unit.
However I would like to suggest a tube preamp that in my opinion will not benefit from tube rolling. That preamp is the Herron Audio VTSP-3. Like Stringreen , I am also a musician, violinist by training and have played for years, and this preamp is the best at rendering musical satisfaction that I have used. It gets all aspects right in MHO. You should check it out, I do not think tah you will be dis-satisfied.
