Now you're talking about frequencies that are MUCH higher than the audio 
band.
Complex impedences take effect.  An improper cable, a bad connection, etc. 
can
cause REFLECTIONS of the signal resulting in jitter.  Direction can affect
signal integrity in this situation.  But that has nothing to do with the 
copper
of the wire.  Remember, this is NOT an audio band signal.  The physical 
design
of wire, insulation (material MATTERS), ground, shape, connectors, etc. 
could
affect what goes on here.
