the usual SET dogma of maximizing distortion.
Is this a troll Krueger or do you really believe your own dumb ****?
In theory SET dogma reduces a certain type of distortion,
Name that distortion. BTW, in case there's any confusion, I don't mean
make
one up!
SET advocates believe all phase splitters are imperfect and so
eliminating them eliminates asymetric drive issues,
Asymmetric drive - small problem
Asymmetric output stage - large problem
Typical toob bigot logic - exchange a small problem for a large problem!
also that push-pull
transformer cores are magnetized and unmagnetized on each cycle.
Only a problem to people who don't believe in soft magnetic materials.
However, even if that's so the core magnetization is ten times worse,
making sufficient primary inductance impossible for good LF response if
HF response is not to be killed off.

It should be noted out of fairness in the case of a deliberately
restricted bandpass amplifier, perhaps one for a treble driver, single
ended can provide better results than at first it would appear.
IOW, instead of being an utter unmitigated disaster, its merely a disaster?
The Audio Anthology provides the example of a treble SET for a horn
driver
that provides 4 watts, and by limiting power protects the driver since
it will handle at least three times that in square wave power at 50%,
symmetrical duty cycle.
Sounds like a good job for a $1.00 (or less) IC.
