RE: Chinese power cable: wow!

"Now I was wondering, as each conductor is shielded + another shield around everything, I was fearing some reduction of dynamics but, in that position at least, I don't hear such."

Glad to hear that the cable is a success in your system!

The shield should have absolutely NO impact on the sound since the shield should not be carrying any current. If you are thinking about interconnects, it is usually because the shield has been connected such that it is part of the return path and carries current - especially for twin conductor + shield adapted for unbalanced cable. For this application, the shield should only be connected at the source end.

With balanced cables, things are a little more complicated because many consumer products with balanced connections have chassis ground different to signal ground. Whereas the pro equipment I have has pin 1 = chassis ground. If you mix and match equipment with different grounding strategies using balanced cables with a straight through pin 1 to pin 1 (for shield) you end up with noise and ground loop issues. Took me a while to trace back to the offending component!

STP network cable has the shield around each twisted pair and this provides improved noise immunity on top of the common mode rejection due to the twisted pair.
