I have had mostly great results with pairing a SS preamp and a tube amp. It just depends on the products that you pair and your ears. For example, I have used a CJ PFR amp with several different tube amps for years - it almost always sounded great. By way of comparison, the Krell KCT - not so great; at least with my tube amps.
Why use a SS preamp? Black, quiet background, usually plenty of inputs, often a remote. It's not the only or even the best way to go, but it has worked well for me. YMMV
