I'm beginning to suspect audiophiles, as a general rule, are a touch slow, as wire directionality and marking cables and fuses with arrows is nothing new. Far from it. Placing arrows on cables and fuses goes back at least 20 years. And the reason arrows are placed on cables is because wire sounds better in one direction than the other. This is not exactly a big secret. Its not Top Secret, it's not For Your Eyes Only. It's not even like the secret sauce on Big Macs. Hel-loo!
