One thing I was wondering was if I use a transformer

a nominal 16 ohm secondary but use it with 32 ohm
headphones for example, then ra reflected into the
secondary would be so low relative to the load that

output could be considered essentially a voltage
source.
Equally the load reflected to the plate would be four
times higher so distortion would be lower?


Language. Lower load = higher resistance.

If you follow my logic, my point is clear. The load
presented by the primary of a transformer comprises:

1. Primary winding resistance
2. Leakage inductance in series with 1
3. Reflected secondary winding resistance in series with
1
and 2
4. Reflected secondary load in series with 1, 2 and 3
5. Primary inductance in shunt with 3 and 4

Think.


Nope, maybe I am just thick. You said "10H is in shunt
with load. Lower load makes shunt more
significant."

Now you are saying "Language. Lower load = higher
resistance."

Which means "Higher resistance makes shunt more
significant"

That means to drive a higher resistance load I need MORE
inductance in the primary.

Does not make sense to me.


I can't see why not. Oh well. I suggested you simulate.
Perhaps flipper can explain better.
