" have just built a new cable with Live, Neutral & Earth and a fine tinned braided shield. I have connected this shield to the ground wire again at the socket end."
My response:
By socket I assume you mean at the male plug end. That is the normal end where the shield is connected.
Because you are dealing with a grounded power cord if the shield drain wire was connected at both ends it would be in parallel with the EGC, (Equipment Grounding Conductor). If you didn't have a ground loop hum to begin with adding the parallel conductor would not cause a ground loop hum either.
Why you would not want to connect the small drain wire at both ends is because in the event of a ground fault event, (Hot conductor to chassis/metal enclosure), the small drain wire more than likely would not handle the ground fault current, even though it is in parallel with the larger gauge EGC.
