Furthermore, I would venture to guess that neither Raul nor Mijostyn is actually making measurements of his audio gear and the signal that comes out of them. They are most likely going by data supplied by manufacturers and their own considerable funds of knowledge about electronics and distortion. But history is replete with instances where measurements lie. In the early days of solid-state amplification, we had amplifiers that measured harmonic distortion in the order of .000001%.
FWIW, times have changed and for the better. We can now measure the differences we hear between components- if the knowledge is there to know what to look for and how to do the measurements. IOW if the measurements are done properly they don't lie.
Time hasn't changed human nature though.
Drawing the line between what we hear and what we can now measure is likely to draw ire from both the subjective and objective camps. The very idea! But if you want to get down to knowing what's really going on, that's what has to be done. The acrimony between the two camps has to end.
