Even is you had correct and reversed in a mix of equipment. It would only matter if a few of the pieces had serious power supply failings.
So if nothing blew up, I say no problem. and no difference in the sound.
Hot / Neutral Reversed
If your entire stereo was connected to that one duplex, nothing should matter. Folk use (I use) "Technical power" (balanced 60v/60v)mixed with normal 120v/0v and it does not matter to the sound in any way.Turntables eat 60v/60v same as 120v/0v too.So generally modern stuff in not bothered by it being 'wrong'.Only if there was a short, or some failure, maybe it would matter. but more so if you had really ancient gear. Modern gear is pretty well protected. Even is you had correct and reversed in a mix of equipment. It would only matter if a few of the pieces had serious power supply failings.

If it was wired incorrectly at the outlet I would check the wiring all the way back to the main distribution panel and use a circuit tester just to make sure. This is a safety issue that should not be made light of in any way. As for the performance of equipment, if you can not tell the difference in the performance and the plug is polarized then I would look for another issue in the system such as damage. The basic question becomes, when the power wiring is correct, where is the weak link. |

I dropped an extra $2 for an extra-fancy version w/ rubber grips on the sides: https://www.amazon.com/gp/product/B000RUL2UU/ref=oh_aui_detailpage_o00_s00?ie=UTF8&psc=1 All the other outlets on the circuit tested fine. It just happened to be the outlet all my equipment used (save my Vandersteen Quatro CTs) that was reversed. |
