I am going to stick my neck out and make you a wager. I’ll bet that if I crept into your home one night and swapped +/- on each of your speakers that you’d not notice the difference.

Yet, in the heat of the moment during a listening session you’d hear the swap immediately—even if you didn’t know what it was I was doing.

In fact, I know this to be true because I’ve done both experiments.

What might we conclude from this observation? That long-term polarity swaps are meaningless, yet short-term ones are noticeable? And, if that is so, why?
