I'm more into the 'vintage' end of audio, so may not be entirely applicable to the OPs situation... but -
I have found the best combination (to my ear anyway) with is the tubes in the preamp and solid state for the power amps.
I run a modified Dynaco PAS-3X preamp into dual Mac MC2100s set up as monoblocks. This gives me the 'warmth' and presence of the tubes coupled with a basically unlimited power reserve (210 wpc out of each MC2100)... the other key is to have speakers capable of utilizing both the expanded bottom end subtleties as well as that high power reserve that such a combination brings to the table.
End result is as close to zero distortion / "muddiness" on those low bass / kick drum notes as is possible within the constraints of a 'vintage' system; combined with a better level of detail and nuance than either an all - tube or an all-SS setup could provide.
Going all tubes looks the 'coolest', of course - but unless your bank account is unlimited, you will face a much lower power output ceiling going with tube amplification. Some will argue that the higher power is not really needed at normal listening levels; I would offer that there is a distinct sonic advantage in having such a huge reserve to handle the millisecond power demands really impressive low notes put on an amplification system...
