I've done it both ways; SS pre w/ tube power, and tube pre w/ SS power. Both have worked depending on the speakers...the most synergistic combo will depend on the surrounding comps, room character and your listening taste. That's our hobby! Right now I do as 'oldheavymec' suggests: tube pre split output to SS for woofers and tube power for mids/tweets. I installed a gain pot on the SS amp to balance things and it locks in nicely.
My gear: not high end...Chinese Zero-Zone CJ clone pre, hot rod ST70 (VTA driver), Akitika GT102, and home brew speakers with Dayton 7" RS woofs, Morel Twee-mid domes and Dayton crossovers. 1 cu ft enclosure ported to 33 Hz cutoff. Also have a Dayton 8" powered sub in the low frequency circuit with DSP to add some extra oomph and eliminate any bass slop from the ported woofers when playing vinyl.
