D'oh! It seems my earlier post about the spike and rounded wavefrom on the
actively balanced program outputs can be ignored. Looks like 200-600 ohms
of load will clean things right up (though much lower R and it gets a tad
worse).

Don't know why I didn't check this out earlier. I guess I thought
the balance trim circuit would have been enough load but apparently not.

Follow-on comments welcome; but it seems I've answered my own question.
Sorry for the fire drill.
