Ron, your post caused me to rethink that situation. Not being a musician, I didn't think of the fifth situation. Let me say that I think that vacuum tubes as well as tape recorders go into saturation rather gracefully which produces second harmonic distortion, but a transistor amplifier is almost distortion free until it (hits the wall) and clips the signal and causes dramatic odd numbered harmonics. Splatter would be a good word to describe the result. That may be the reason for the tube preference. I still think that you couldn't tell the difference if you kept the volume at a reasonable level. Nowadays transistors are capable of lower noise than tubes I believe. I don't doubt that transistor amplifiers could be designed to have the same distortion as tubes, but you couldn't sell them, preconceived opinions being what they are.
