Thanks for your answer, Richard; from my point of view (my knowledge),
what you win is less circulating currents all around the output stage
(less I2R losses); what I want to ask you, is, what do you mean with
more "headroom"?, is that the ac voltage signal (always for the same
power output, 100 W) will have a higher upper limit in excursion before
flat-topping? and so, less distorsion, ¿is this what you mean?.
