Right-on! The PS in a SE amp is most important
because it must have the same hi-fi qualities
as the so-called "active" circuits on the
other side.
Alternating current always has two sides, so
for practical purposes, a SE amp IS "push-pull."
It's just that the PS side does not contain
amplifying devices-- that means that you don't
have to listen to one side of the circuit battling
against the other side-- only one side is active, so
things are much more friendlier-- towards music.
Dogfights are more active when there are two dogs.
When both dogs are exactly alike, the dogfight
would end when the two agree with each other.
When one dog is different from the other, we
have distortion-- of the dogfight-- the two dogs
don't agree with each other, so they both distort
their surroundings with the dogfight!
This is, of course, the bane of all p/p and
"balanced" circuits.
They are never "balanced" because two tubes or S/S
devices that are identical to each other don't exist.
Dogfights involving only one dog are less
offensive, but the area around the one dog
now becomes much more a part of it!
That is why SE lovers can't stand p/p and
balanced circuits. The system rejects the area
around the performance to some degree.
Engineers call this reduced distortion.
Music lovers call it what it is: rejection
of ambient cueing....
