Tube vs solid state is a matter of personal taste. The distortion that is mentioned with quality tube integrated, or separates is low enough that the ear does not perceive it as bad unless it gets harsh sounding. By the time that happens the shingles on the roof are rattling lose from the high SPL. :) It does not take great power for creating great sound. It does take a robust power supply, and quality design, components, engineering. I'm my opinion, tubes have a warmth in the voice range, and and sound in the midrange which usually will be noticeable.
Solid state has the punch, the quick hit with a drum and speed that seems effortless in music. Probably due to higher damping factors.
I think tubes give flexibility by allowing pre amp or power amp tubes to be changed for different preferences in sound. With solid state "it is what it is" I also think Orchestra music shines more with tubes. Strings have crisp vibe to them. Voices can be velvet , smooth yet detailed.
Rock music, solid state with a pair of JBLs is tough to beat.
Everyone's ears are different and have individual preferences.
It's all about what you enjoy. My pick is tube.
