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.
Have you ever turned on your system, only to find
the sound was totally wrong? Nothing focused, imaging gone, soundstage just disappeared? The bottom end had no impact, the voices were from everywhere, yet when I moved my position slightly left or right, the voices moved in that direction. The music sounded as if it jumped from in between the speakers out into the room very close to my chair. I was going nuts! I repositioned the speakers for the next 4 hours only to find that whatever I tried wouldn't bring back my marvelous sound.
Then I remembered I swapped cables between amp and pre last night. The pre has 2 outputs, one inverted from the other. I plugged both into the right side, one normal, one inverted. What a boob! Anyone have similar mis-steps they would like to share?
