best tube preamp under a 1000 for B&K 200 sonatas?


I have a pair of the B&K mono block sonatas...currently using a B&k ss pre....I would like to step into a tube pre but don't want to spend more than a grand. Definitely buying used. Running paradigms studio 60's. All suggestions welcome. Thanks

Can you explain a quickly about the output impedance of the preamp? What should I stay away from? I have seen a few Carys on here in my price range.,also what about eastern electric min max?
