Did you mean connectors? or wires? Of course, all signal conductors have two paths, even if one is the Earth. I have never seen an RCA plug that didn't use the center for one, and the outer connector for signal ground. Even the mega dollar WBT really use the outer 'shield' for the signal path. > A fairly common wiring layout for home-built cables is to use dual-core > cable for the signal and to connect the shield to ground at one end only. OK, I'll accept that as a reasonable exception that proves the rule. It is probably safe to say that 99% of all RCA/phono equipped cables in the world have one center conductor and use the shield for the other. Clearly some home built and mega dollar cables can have different structures. -- Pat http://www.pfarrell.com/music/slimserver/slimsoftware.html _______________________________________________ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/lists/listinfo/audiophiles
