RE: Has anyone tried these.

"...why don't those tubes simply dominate with their distortion levels printed on the box"

Well I don't know about distortion specs printed on the boxes but the linear tubes do dominate.

6sn7, 2a3, etc. are very linear tubes and that's why they are so widely use for audio.

BTW It's not sound that is measured by the traces of a curve tracer. It's the electrical function of the tube that is being represented. But the electrical function of the tube determines the distortion (or lack of) of the output wave form. If the tube's function is non-linear then the output wave form will be distorted (misshapen).

"...best most enjoyable sound..."

I think you are now getting to the root of the issue.

There are different types of distortion and not all distortion is heard as equally detrimental to the perceived sound.

Then there's the question of personal preferences. The person who often listens to live un-amplified instruments might have a better understanding of which playback systems sound more like the real thing and which systems do not, with no regard for personal preferences.

Others might like the sound of a system based solely on personal preference, having nothing to do with what the instruments actually sound like and nothing to do with anything technical.

I guess in that case it's all "magic".
