Seeing/hearing and sighted/blind tests

Are you unfamiliar with Stax electrostatic headphones? They are called
'earspeakers'.
That's what Stax calls them. Everyone else calls them headphones......
You simply attach the cables coming from the Stax
transformer to the speaker outputs of your power amp. The headphones
are polarized by AC current, and the power amp supplies the signal.
They are extremely accurate and fast transducers. If you have a chance
to listen to them, do so.
I have listened to them many times, and I have a particular affection
for the Lambda. Perhaps it's a certain lack of familiarity with the
Stax *range* which prompted your challenging the question, since not
all Stax 'phones are self-polarising. Also, the questioner may have
wondered if you had hooked up a dummy speaker load in parallel with
the 'phones, in order to provide a more rigorous test of the power amp
while at the same time using a highly sensitive listening tool.
Clearly, you did not.
However, this has nothing to do with your refusal to understand that
*sighted* testing is useless for the discrimination of subtle sonic
differences. Also, unless you are intending to use *only* the Stax
'phones with that power amp, it's a very poor test of a power amp,
since hardly any power is required to drive them.
