[time-nuts] Rb references for audiophiles?

Jim, "directional" audio interconnect cables typically have two conductors 
for the signal path, plus a shield. The shield is connected at only the 
"destination" end of the cable. This is similar to some low-level 
instrumentation connections (where the signal flows through two inner 
conductors, and we don't want the shield contributing to circulating AC 
ground currents).

The situation for "directional" speaker cables is a bit stranger, but, 
again, typically involves a shield connected at only one end of the cable.
