Doesn't everything?

If I use an RTA or FFT analyzer I can see that there is no real
change excpect for a brief transient during polarity switch. With the
FFT you can see the level of each individualfrequency component and
none of them change.

So that proves that nothing has changed but the polarity, yet you hear
hear the change. Hence you an hear a difference between normal and
inverted polarity. QED

Any change you hear is due to phase errors in your speakers and is
totaly random.

Uh . . . . out of which monkey's ass did you pull this "fact?"

Have you tried it on headphones? People come up with all sorts of
excuses of why they hear what they hear. Some people have said that
they could easily hear the polarity change on their computer speakers
but not on their "hi fi" speakers so it must be because the computer
speakers aren't very good. (couldn't be that the "hi fi" speakers
aren't any good, could it?) Whatever the reason, you CAN hear the
difference, and that's all I was trying to demonstrate.

Lots of people listen to music on computer speakers or headphones.
