Electrostatic speakers and phase/polarity inversion

My EE Minimax preamp evidently inverts phase (or polarity). Not sure about the proper nomenclature but you know what I mean (I think). One solution is to invert your speakers connections but my question is, does this work the same with electrostatic speakers vs conventional speakers?

Both coil driven and electrostatic speakers see AC signal, so there will be no difference.

Polarity is the appropriate term.

A polarity inversion can be fixed by swapping "+" and "-"; a phase shift (even one of 180 degrees) cannot. Phase is a time dependent quantity
Yes, the polarity convention of an electrostatic speaker is (should be!) the same as a dynamic (permanent magnet driver) loudspeaker.
It gets a little arcane with some of the (vintage) compression drivers from, e.g., Altec and JBL -- which is why I bought myself a Cricket.

If one is ever in doubt about polarity, one of these comes in extemely handy, IMO. Not exactly Old World craftsmanship, but they're inexpensive enough and they do work.
