If looking at tube preamps, make sure that they are comfortable with the input impedance of your amp. We just introduced a tube preamp in this price range and FWIW its OK with that impedance.
However I agree with others here- make sure your system is set up as best you can before making changes to the equipment to further your goals. It can save you a lot of money!
