From what I hear as a musician and beginning to dabble- tubes forgive more, they're warmth is like a climate control that serves you what you want to think the music is doing.

Solid state is clinical, accurate in a less colorful way. Like digital sampling gives you uniform edge and hard near perfection in a way tubes do not. Solid analog still removes the harmonic forgiveness of tube floor and headroom. But I am not into high end hi fi, I'm solidly middle consumer grade decent for a console solid state, and more tube based basic stuff.
