Directional interconnect cables

DCstep, is this correct? I thought you always pointed in the direction of music flow i.e., source to preamp, preamp to amp and amp to speaker. Doesn't this assure that the grounded end of the shield is properly oriented? If not, I've been doing it wrong for 20 years.

Rodman99999, I spent thirty years with AT&T. Tell me more about the industry's stand about cable directionality.
I never heard it. What are your sources? Not an attack, I just want to know.

It is a pointless and circular discussion. Trust you ears and don't listen to any pseudo-scientific explanations of cable theory. In a hobby that is immersed in hype, hyperbole and BS, cable, is without a doubt, the most extreme of all. If you like a $10,000 cable that is all that matters. If you like a $10 cable the same applies.
No one can, using the scientific method, prove that burn-in
is audible.

I don't understand either but people hear what they hear and believe what they believe. The one thing I've learned is, apparently, the directional arrows don't always mean that cables should be installed in the direction of music flow which is intuitive but, instead point to the grounded connection. I never knew that and don't consider it intuitive.
