It's there!

In the far field. Near field tests that show any measurable
amount of it are still highly suspect.

The point is that AM distortion, which dominates and is relatively large in
speakers, and often pretty audible, is only present in good electronics in
far smaller quantities. Masking rules, we hear distortion in speakers far
more so than in non-clipping, non-noisy electronics.

OTOH, aren't the AM products that speakers generate mostly
the "warmth" generating kind that people seem to like in
small amounts? That's not to say that it still isn't
swamping the smaller effects.
