Audiophile circuit breakers ?

Gs5556 -> I live in Europe, in Poland to be precise, so I have an DIN compatible breaker box as standard.

The voltage may not be an issue (if anything, the voltage in Europe is higher than in the US). However, the mounting standard may be another story.

In any case, I'm surprised that no one tried to market circuit breakers in the US yet.

Elberoth2, here in the U.S there is a sticker on the panel, that more or less says, only breakers UL listed for this panel board shall be installed in this panel board. That means same manufacture. I think the manufactures had a lot to do with the listing.

At one time Rick at Virtual Dynamics sold cryo'ed breakers. Cryo'ed seemed to make a more relaxed presentation of the music. All the breakers, I believe were UL listed. I am not sure if they still sell them. Anyways, the difference in sound was from the cryo'ed treatment and not so much the breaker itself. Just guessing on the sound difference. Quick silver treatment also applied to the breaker and the bus bars also improves the sound. Be careful when working inside your breaker box.
