Audiophile Grade Wall Receptacle

@mitch2 

No, I can't cite a specific example but the same can be said for a duplex.  Power is coming from the panel box which is noisy to your outlet.  Again, I am not an engineer and no very little about electricity.  Where is the source of the noise coming from?  Just getting an upgraded outlet is not enough to me.  BTW, QSA has upgraded circuit breakers in addition to upgraded outlets.  The main attribute of an upgraded circuit breaker would be a cleaner quieter signal.

I agree with you on an audiophile circuit breaker , using the audiophile forum I found this https://www.akikoaudio.com/en/products/570-05-akiko-audio-cylindric-fuse-cartridge-english .

But I believe that this would mainly or possibly only useful if you have a dedicated line but at least the breakers are available at a reasonable cost .

Thanks for the link.  I am sending an email to the company to get more information on the circuit breaker.  I do have a dedicated 20amp line for my two-channel

system.  

The Quantum Science Audio Ultra Black-Red AC Outlets are by far the best I’ve ever tried period ! 😍😃 Not cheap but worth every penny though !

@rick2000 -Did you consider the QSA jitterplug prior to buying the duplex outlet?
