Run some numbers, it's very interesting to watch. You still get a dramatic
increase in distortion near the zero crossing. It's enough distortion you
can use that old HP 334 and see it with a test jig.


** There is NO distortion in the arrangement AS SHOWN !!


Everything has distortion. Nothing is completely linear. It's how physics
works.

Check out Doug Self's book on power amplifier design. Again, the issue
isn't the frequency response, it's distortion from the ripple across the
capacitor.


** Which does not exist in the circuit shown as the 10uF caps are DC biased.


DIfferent issue, not related to DC bias. Again, check out Self's book.
