"The only way that would be possible is to compare listening through the switch to listening without the switch and extra cabling. The box is used or it is not. That would be the necessary control to replace the assumption set."
Alternately, if one were to assert that covering a cable with magic marker changed it, one is stuck either measuring the effect from the standpoint of electronic theory OR by asking if anyone hears any difference.
The electronic theory approach used to design things says if the effects are small enough, they will not be detectable, the idea with the switcher is that to do this test one must compare so what matters is the stray elements are very small as they were (like a few inches of cable).
The point is that once no one knew which was which, the differences that they heard went away, that part was a blind test, if you really can't tell which is which or a difference between A and B using only your ears, the differences are very small..
The usefulness was in showing everyone just how large even dominating what they expect or know was relative to the actual / detectable acoustic changes the different speaker cables imparted relative to zip cord.
That part was huge, totally unexpected and humbling for some who were totally "sure" about their cables.
One can debate everything makes a difference even a flyspeck of dust in the room and it does at some level, but until one removes prior knowledge from the test, one is not measuring what your ears hear but an opinion which encompasses what you know and believe as well..
