Skipping back a few....

You'd have to bury an awful lot of copper in an awful lot of salty mud to get anywhere near the low impedance of a good bonded earth.

I'm not one for cables but if I were then the logical end point has to be point to point direct wired with no RCA sockets or wall sockets. If one thinks about the difference between various spring contacts in wall sockets vs no sockets at all one would have to conclude that fancy sockets are just an expensive stop gap. Surely ;-)

Because the only logical end points are no sockets of any kind or replacinlg all you wires with long chains of sockets.
