The transformer raises the impedance a bit. (What do you loose??)
I repeat this: As I get more and more familiar with the new generation of
plug in power generators, I get more and more suspicious about what happens
when the generator is idling.
Before it used to be only a resistor, no harm, but today the PIP is
produced by a current regulator.
The intention is good, to bring up the input impedance - but what happens
when it is idling?
Besides, different recorders probably behave differently.
If I couldn't sleep unless I had taken a grip into this, I would connect a
capacitor in series with the signal and a suitable dummy-resistor over the
input, creating a load, as from a PIP microphone. See if I got a difference...
