Brass is the (costly) way to go.

Hi.

I have seen some audiophile grade power strips & powerline conductors installed in housing built with thick shiny brass plates, asking for big bucks.

Quite a few willing audiophiles find such brass plate housings improve the sound vs steel or plastic enclosures. Believe it or not?

From RFI/EMI shielding aspects, thicker the shielding enclosure will get better absorption loss to more I^2R loss inside the shield material. Brass, being a largely copper+ less zinc alloy, is more conductive than steel which is perromagnetic. It offers much better reflection loss to
high frequency noises (beyond 10MHz).

It worths giving it a try if your local brass plate supplies won't charge you too much.

PS: many musical instruments are made in brass, right?
