When you say you "hear a difference between signal cable", I certainly
hope you mean that you have a friend connect the cables, without
telling you which ones you are listening to.  You don't have to do a
production number with a cast of thousands, just use common sense. This
is what you meant by a "listening test", isn't it?  This is effectively
"double-blind" as long as your friend doesn't talk to you during the
test.

Look first for the beam in the eye of the experimental procedure,
before looking for the mote in the eye of the audio signal. (Note:
this metaphor is probably a result of the fact that we used to play
with Mercury, coat dimes with it, roll it around on our tables, etc. in
high school Chemistry lab.)
