Iv'e noted sizzle or "micro-arcing" from Zinsco brand circut breakers (common in older houses) you can actually hear coming from the breaker with heavy load applied. When different re-conditioned (no longer available new) or used circut breakers exchanged in audio circut, difference is quite audible. With a dedicated circut I am beginning to think the main quality difference is in the straight run of wire instead going through a series of brass screws on receptacles, Will start a new thread soon on my home setup.
Dedicated Lines & Power Conditioners
I currently have a Running Springs power conditioner in which all of my gear is plugged into. The RS is plugged into one of my two dedicated lines. Is this overkill? Could I get away with a less expensive PC? Does one really need high end power condtioning when using dedicated lines?
