"I'm not sure people really understand what distortion means. How is it considered to be good when listening to music, and tubes apparently doing much better job versus solid state"
More nonsense @jumia . I like tubes as well, and use them, but you're criticizing.solid state and asking how distortion is good when listening to music, yet it is known that tubes produce more measurable distortion than solid state devices. I don't know what your point is, but whatever it is, you're not expressing it clearly.
