If you can understand why the sonic charcter of any system is determined 85% or more by the amp/speaker (and speaker cable) combo, then you'll understand that if you want "tube sound" then you need a tube amp -- i.e., a tube preamp and a ss amp won't do it (contrary to what many people think ;-) Also, tube preamps make tube noise which is amplified by the amplifier. Tube amplifiers by themselves (genreally speaking) make no noise.
I drive my McIntosh MC275 with a Mark Levinson 26s preamp and the system is quiet, fast, and beautifully balanced sonically speaking. The main attributes of a preamp should be accuracy and blackest background. Since preamps do not process (amplify) the signal, but rather simply select sources and attenuate their output (volume control ;-) there's not much they can do to adulterate the signal, so may as well have a quiet preamp and go SS IMO.
After that, the amp and speakers will determine what your system actually sounds like.
