I had an electrician put in a new 20 amp circuit he had the polarity out of phase. It pretty much made a mess of the sound. It was about 13 years ago at this triplex that I used to own. Unfortunately he wired it up at the box using the existing outlets and wiring just put on their own circuit. It took me three days to figure it out what was going on. once I put my system on extension cord to the kitchen outlets, it sounded like its old self again. I then bought a plug tester. That is when I found it out of phase and with a floating ground. I now always check to see if the polarity and the outlets are now wired correctly when I set up any system. It is a great tweak to make sure you have good power. I stopped payment on the check to the first electrician an hired another electrician who came out and fixed the polarity plus having to re-do the whole thing right. Once my system was on the new and corrected dedicated 20 amp circuit it sounded better than it ever had, and it was a huge improvement.
