Hearing other appliances in dedicated line


Hello

Recently I started hearing clicks through my speakers when I power off my tv or change speeds on my fan. My system has a dedicated 10 gauge line running from the circuit breaker panel. Never had anything like that happen before. No changes were made to the system. Any help would be greatly appreciated.

Is your audio system breaker on the opposite leg (phase) as these appliances? That could help.

So big a deal was my discovery years ago that some of the ground wires were not tight inside my 200 amp breaker box Stereophile published my letter to them about it. Taking proper precautions,I hand tightened every wire inside that breaker box. My issue wasn’t clicks but rather, hum. Never heard any anomalies again.  

I have a 4 wire dedicated line one common ground the other a insulated isolated  ground on its on buzz bar and grounding all wires awg 10 Copper

as well as outlets gold over Copper , very quality .
