The circuit that Al devised or spoke of was a referred to as a " Anti Parallel Diode" set up where two rectifier bridges were placed back to back to create a one way gate ...

Any fault or short in the component would pass through the one way bridge to and down the safety wire to the ground rod

Any ground transients or RF coupled to the safety wire trying to invade your component through the component's safety ground system would be blocked by the bridge's one way action

There is a safe path to ground and a gate keeper at the entrance to block or suppress noise ...

Search General and Tweaks for ... "anti parallel diodes" for Al's actual posts and comments

Apparently Bryston feels this is a big enough problem that they are addressing this issue by installing just the same circuit in some of their amps

See the attached photo and look at the Bryston amp schematic on the top ... follow the ground off the IEC and it sure looks like what Al was describing

Also note Bryston seems to have a concern for DC off set ... follow the neutral off the IEC to a circuit that looks like the circuitry used in a typical Hum Busters

For more info on the ground noise issue ... goggle ... Ground Transient Blocker or Suppressors ... these are pricey but UL approve I think
