Many listeners have heard better sound using Zero Impedance transformers
even when the load match was OK in theory; ie, when the load value was
raised higher than "it should be" and the load is "underpowered", the
music sounded better, and so it should have because the THD was lower,
and DF higher. The "underpowered" load match means less maximum PO is
available abd in SE amps it means clipping is asymetrical because the
wave clips onj one side due to grid current before cut off occurs. But
who cares how the amp clips if there is **enough** power before clipping
occurs?
Not to mention that asymetrical clipping is more musical than symetrical
clipping.
