Tweak your AC mains for better performance, free


If you haven't done this before or recently, try it. It will improve the performance of your audio system, particularly if you have an older circuit panel in your home. Go to the AC circuit panel. You'll have a main breaker that runs power to all the circuit breakers in your home: turn that breaker off and back on. This will shut off all the power to your home, momentarily. Then turn all the breakers on your panel off and on. By the way, electricians recommend doing this once a year. I hadn't done this in several years (I always forget) but, I happen to remember it because one of my breakers had shut off. Anyway, after I performed this simple on/off task, the next time I turned on my audio system, the sonics really improved. The soundstage had opened up with more width and depth, fullness was improved, and so was the overall resolution and presence of the system. I noticed it immediately, and then remembered that earlier I had flipped all the breakers on the panel. I don't have a dedicated line yet, or any fancy custom audiophile breaker panels, but the results of this simple task proved once again the dramatic affect AC delivery has on what you hear from your sytstem. I can only imagine what one can hear with dedicated lines, custom breaker panels, and audio grade outlets. For me, the best I can do now is a power regenerator that I just ordered a conditioner and a few good outlets. My system: LSA DK Signature Integrated, Modwright Sony 999ES (tube rectified PS 9.0), Acoustic Zen Reference Matrix II IC's, Jolida JD 100, Acoustic Zen Satori Speaker Cable, Shunyata Hydra 4 PLC, various aftermarket PC's, FIM 880 outlets.

On the other hand, you could not pay your electric bill for a while, I am sure they would be happy to cycle you switch...perhaps having it in the "off" position longer would have even greater benefits than just the the momentary interruption...just a thought....
Tgrisham, as Reb1208 suggests, the wiping action of the contacts in the breakers (especially after a couple years of oxidation) created better surface contact and created a better electrical connection. (I assume this is why electricians suggest this be done at least once a year) That's where the improvement in electrical delivery originated and that improvement ultimately affected system performance in my opinion.

You're being dismissive and presumptuous. I guess that's your style.

It's definitley not a case of a person hearing what they want to hear. I know my system and room extremely well and the change in performance afterwards could even be heard a room away.
The improvement that Foster9 is experiencing is probably due to the cleaning that occurs when the switch is opened, then closed again. I do the same thing but take it further by first, opening the 200A main breaker and removing it. Then I clean the copper buss contacts with 600 grit sandpaper and 99% isopropyl. Clean both the buss and the breaker contacts. Finally, use quicksilver gold contact enhancer on the freshly cleaned copper. Do the same for the breaker feeding your audio, then reinstall everything. Maximum results occur once the quicksilver breaks in thoroughly. Please don't perform this tweak unless you know what you are doing, particularly the 200A breaker (the wires feeding the 200A breaker go out to the pole and are live).

You may have a faulty breaker with high contact resistance causing too much of a voltage drop to the AC power reaching your system. I'd call an electrician to take a look at that panel. Any undue warmth will indicate a serious problem.
