@tvad,
...One of the benefits of tube amplification is the differences in sound possibilities. ..

Yes. Very true, tube amps offering switchable triode / ultralinear is fun. And, flavoring sound using different sounding input/driver tubes (various). In addition some of the better designs permit varied use of different EL34, 6L6*, 6550, KT77, KT88, KT90, KT120s, and some recent designs permitting use of KT150s. Thirdly, changing coupling caps offers other flavors of sound. Very tunable to taste once learning some of the signatures from different tubes. Best to have friends with similar tube amps to loan/compare tubes. Super tunable to taste - great flexibility.
With solid state pre/amplification, pretty much locked in (take it as-is) excluding maybe playing around with different interconnects in an attempt to passive EQ the sound -OR- this is when the speaker-change rollercoaster ensues. It’s also a benefit with SS, fewer options keeps one away from the very tempting tube rolling rollercoaster with tube amps.
