Power Cords & effect sound?

[Audio_by_Goodwill]

Just moved into a house that was built in 1955. No grounds anyhwere but the service entrance. No grounded power outlets - so no grounds for the audio. Power was also dirty. Just one 220V (+ neutral) line pulled out to the shop/listening room. Everything running from that. Turn on a light, hear a pop.

So I added a made ground. 8' copper clad grounding rod right outside. Not more than 6' from my audio supply outlets. And an isolation transformer for the audio circuits.

That's vastly different than what the super expensive boutique power cables give you.

Well, yes. But I didn't pay much for it.
