ground noise isolation


Several months ago, I started to hear intermittent buzzing in my system, about twenty minutes of every hour. It comes and goes. I still haven't figure out the cause but I have determined it's coming through the ground. I purchased a regenerator product with battery backup. When I pull the pc from the wall the buzzing goes away and when I plug it back in it comes back. The regenerator manufacturer says it has to be coming through the ground.

What's the best way to isolate the ground from my system? Would an isolation transformer work? If yes would 2.5kv be enough if my draw is 1000 watts?

I have a dedicated line and only play vinyl.

Refrigerator cycling on/off?
Fluorescent light?
What's a smart meter?

Are you in a single family dwelling / duplex or / appartment?

Sometime neighbors can generate some nasties on a power line, even the next door variety.

2.5kw iso transformer will work OK and should be good up to 1000 watts but only if the power factor of the load is high enough.
Does your kilowatt run ok now, from the wall?
