It cannot be validly used to describe a significantly distorting amplifier compared to one distorting less.
Natural does not have a precise technical meaning and so can be used to describe a significantly distorting amplifier without being an absolutely false statement. One can object on qualitative grounds if inclined but things are not black and white.

I do not hold audiophile beliefs and would be offended to be called an audiophile by a person outside the audiophile world although I do appreciate you do not mean it in a derogatory way here.

No problems so long as you avoid terms with precise technical meanings you should be on safe(ish) ground.

Possibly. From the evidence in these pages (my only real exposure to audiophiles) there certainly are audiophiles who appear uncomfortable with their beliefs and seem to be threatened by a more scientific view. Nonetheless, I suspect they are probably in the minority and, as far as I can judge, most have few problems dismissing contradictory information when it intrudes from the world outside.

??? Then it will be audible?
