Rhodium plated audio grade wall socket

Is this snake oil?

I am renovating my house so have the opportunity to overhaul everything including the electrics. I am having a dedicated line from the breaker box/RCD to my hifi equipment. Will adding these types of wall sockets also help reduce interference from other household appliances, routers etc? What does Rhodium actually do in this case? It’s less conductive than copper, silver and gold.

Any thoughts are much appreciated.
