I agree with Jdombrow, you should try borrowing one and see if the sound works for you. The "warm tube sound" is a generalization. There are incredibly transparent tube preamps, and very warm,rich, syrupy ones. And everything in between.
If you don't have any complaints about the sound now, what is it that you're trying to improve on?
Some options in about your price range that I think are pretty good for the price include the Marsh P2000t and Audio Mirror T-61.
