Measurement of sound does not equal perception of sound.Then why arguing about or against cable directivity?
By faith or superstition?
oups! i forget....
You claimed that all perception not reducible to measures are placebos for sure....
But wait a minute if some perception are not illusion or placebos , even being non measurable this way by a voltmeter or a frequencies meter , psychoacoustic made sense anyway....And perhaps for the cable, changing his direction is a particular "measure instruction" to experiment with by listening to it? A way to CORRELATE a physical information to an audible perception...
And perhaps cable direction made sense being an instruction to experiment with....
Then is all perception of sound reducible to known measurements or not? Say yes or no....
If like you just said measuring and listening are different why do you ridiculize those who experiment with it in the affirmative?
