QSA Audiophile Circuit Breaker


US, 20A Breaker With QSA Treatment


Tweek Geek Speek Blog Review of the QSA Black/Red breaker
This panel mount audiophile circuit breaker is rated for 20 amp circuits and certified for home use. They have been treated with the QSA process which transforms it's performance when powering audio equipment.
We highly recommend using the QSA treated circuit breaker with a QSA treated AC receptacle. This combination is highly effective at lowering the noise floor, and providing power to your components that will allow them to perform with unimaginable clarity, depth, and naturalness. You won't believe you are listening to the same system!

Results In Our System


Before the QSA Breaker, we had a builder grade common 20 amp breaker connecting our audio circuit to our studio system, we had a short run (12 feet) of high quality 10AWG wiring in the wall from the breaker box to the Gold QSA wall receptacle. Our Kiyora power conditioner was plugged into the Gold QSA, and we were using both plug and iec jitter adapters from QSA on our other components plugged into the Kiyora. So as you can see, our system had plenty of QSA power products installed prior to the circuit breaker, so our expectations were moderate.
Bottom line, the circuit breaker provided a MAJOR difference in dimensionality, naturalness and liquidity of the music being produced by components in the circuit. It went way beyond our expectations.

Choosing The Right Breaker


Circuit breakers for the home come in several brands and sizes. You will want to pick the same brand that is matches your breaker panel. The easiest way to find that out is by opening the front door on your breaker panel and taking note of what brand and model is currently used in it. We have several listed here that cover most available breakers. If your breaker looks different, take a photo of it and any branding/ model numbers it may have and email us with the photo and information. We may be able to make a custom breaker.
We do not treat GFCI type breakers, as the treatment itself will trip the breaker during the process. We also limit treatment to single pole breakers only.
