Tube Preamp with Solid State Amp?

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.

^^^ @ clearthink,
 to"dip a toe"in any waters is to start as small as $ possible with maximum gains..An inexpensive tube buffer would exhibit all the basics of how tubes affect the sound including true staging & instrument separation,depth of stage & tonal saturation...

I have been doing this since the 80's Conrad Johnson Premiere  2 with Adcom GFA 555. loved it. It really stepped up the dynamics of the Adcom. Audio Research LS2B with Krell KSA 100s. Softened up the Slam in your face of the Krell. Today still Audio Research LS 27 with ARC DS 450. CJ or ARC tube preamps work well with Your Parasound. 

I'm sort of at the opposite end. 
I have a solid state preamp and tube amp(s). I use multiples of subwoofers and I don't think tube preamps are up to that challenge.

I have a Luxman Cl38U SE w/a Bryston 2.5 SST2 powering a pair of Aerial 5T's. Gives me a nice detailed top end. Eliminates some of the harshness from streaming music.
