somebody please explain why anyone cares about a polarity inversion to
both channels..
Please don't tell me that you can hear it.
Sometimes you can hear it, sometimes you can't. It depends on the
program material. But it's easy enough to get it right, at least on
your end, so that you might as well get it right. What happens on the
listener's end is anyone's guess.
Here's an example that you can hear:

You'll notice an apparent change in the low frequency content halfway
through when the polarity inverts.
I do hear a diff but it depends on where I am located relative to my 2
speakers.
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.
Any change you hear is due to phase errors in your speakers and is
totaly random.
