RF is like germs. It’s like Chickenman. It’s everywhere! We're drowning in a sea of photons. Since RF travels at lightspeed it’s eveywhere at the same time. It’s inescapable. It infiltrates any and all holes or gaps anywhere. It enters the unused wall outlet prong holes wherever they might be. RF then contaminates the house wiring (unshielded), then RF enters the electronics via power cords. The PC shielding only protects against external RF. Hel-loo! Regardless of the metal chassis. Since RF is also produced by microchips INSIDE electronics such as CD players not only is everything inside the chassis contaminated but the signal going to the amp or preamp is also contaminated. The enemy is inside the gates!
Seems like any equipment in a metal case is protected from rfi
Looking atFaraday cages in Wikipedia
Here's a quote:
A Faraday cage operates because an external electrical field causes the electric charges within the cage's conducting material to be distributed such that they cancel the field's effect in the cage's interior. This phenomenon is used to protect sensitive electronic equipment from external radio frequency interference (RFI). Faraday cages are also used to enclose devices that produce RFI, such as radio transmitters, to prevent their radio waves from interfering with other nearby equipment. They are also used to protect people and equipment against actual electric currents such as lightning strikes and electrostatic discharges, since the enclosing cage conducts current around the outside of the enclosed space and none passes through the interior.
Why are we trying to quiet the rfi to and from our amps, transports, etc when the metal case already does it?
