You can hear if the system phase is inverted at the XLR by pin configuration or the preamp my design is phase inverted, and tube preamps have a history of this and the manufacture notes that in the owner manual.
My dealer told me never to switch the + & - at the speakers, always at the amp. I have tried it both ways and you can hear a huge difference, I use Dynaudio Confidence 5's.
Switch and the speakers and the sound will thin out and lose some impact and dynamics, switch at the amp and body and the bass dynamics come back.
I get more results than using the polarity switch on my cd player. Bound for Sound wrote about this 20 years also.
This has nothing to do if the CD is recorded properly. We start with the system then check your LP or CD if imaging is poor, and bass is not tight with impact.
This is not even hard to hear if you go to live concerts and train your ear. Perhaps some system will not show it as much, but my speakers have no problem letting me know something is a miss.
