Oh, brother, one of the A Boys checks in with his usual failure to grasp the whole directionality thing. Doesn’t any one of the electronics EE pretend gurus even understand what directionality is?
Once again, we have an amp manufacturer who never got the memo regarding advanced fuses, fuse directionality or wire directionality, including HDMI, Digital Cable and power cords. I have one word: hyper circuit focused!
Man that’s some thick sarcasm if I’m interpreting it correctly, but if indeed you are being sarcastic, Bravo to you! Anyone claiming directionality in a conductor made of 99% pure copper or silver is selling snake oil. Absolute nonsense.
And to answer your (poorly worded) quiz - MOST signals on audio cables are AC - hence destroying the stupid "directionality" argument. LOL.
