I tend to agree with this. How to determine absolute phase in a multimiked recording where absolute phase can vary by mike?
I set my system from source (cartridge/DAC) to speaker cables to be consistent and not change absolute phase as best as I can. Then I just play music.
I took into account my amps gain stages (2, so invert and than invert again, no overall change) but they are cap coupled (looks at amp suspiciously, "have you been fooling me all along?").

With my CD playback system I can switch polarity on the fly. With some recordings -- not all -- I heard a difference. But only a difference not necessarily better reproduction. Some of this phenom may be what it takes electronically to reverse the phase. My guess is that to get a true idea of phase differences is to simply flip the speaker wires leaving everything else the same. Then there is the gain stage count to determine if your system from source to speaker terminals is in phase or "out of phase." Capacitor coupling twists things further by 90-degrees.
My recommendation? Don't worry about it -- it will drive you nuts.
