iF the distortion spectrum is 110 db below the principal tone, does it matter what shape it has?
Your assumption is that with dynamic musical content - quite different from a sine wave - is that the performance will necessarily be the same. Engineers like Nelson Pass have proven otherwise.
"The resulting complexity creates distortion which is unlike the simple harmonics associated with musical instruments, and we see that these complex waves can gather to create the occasional tsunami of distortion, peaking at values far above those imagined by the distortion specifications."
Remember the old Crown gear like I used in high school with 0.05% THD/IMD? That should have been inaudible, right? Surely you don't believe that!
