[cable directionality]
"It’s not a concern for their* particular forms of use."
"Cable directionality" must have some physical manifestation, even if it's at quantum level. The "good" direction must be consistently more effective in energy/information transmission. Otherwise it's distortion which cannot be "good"(local entropy variable) . Energy/information transmission efficiencies mean lives can be lost or saved and money made. One would think this could be of concern.

"...directionality is sound related only"
So only some select audiophiles can measure with their ears local entropy of cables conducting electricity? This skill or knowledge is not available to anybody else and no instrument can match human ears?
