Fuse directionality is a myth...prove that to yourself by reversing the fuse in any component and note that the sound doesn't change one iota, regardless of the hyperbole and silly claims otherwise. Also it bears mentioning (again) that the little wires and circuit board traces aren't installed with any thought of their directionality, thus rendering the tiny fuse wire's directionality utterly irrelevant. One may ask, "why do so many claim unmistakable sonic attributes due to Special Fuses?" Because they can, and subjective opinion, expectation bias, or mythology based belief is by it's nature difficult to dislodge from the faithful, or anybody motivated by commercial incentive over objective logic.
