My hunch is that 95% of IC "manufacturers", particularly the one man operations of under $500 IC’s mark directionality because they think it lends the appearance of technical sophistication and legitimacy."
Question: Why on Earth would anyone in his right mind mark his ICs or speaker cables or fuses with arrows just to lend "technical sophistication and legitimacy" to his products? You know, since many or perhaps even most audiophiles are JUST LIKE YOU and don’t buy into the whole wire and fuse directionality thing. Hel-loo! Please refer to my post last week regarding PATHOLOGICAL SKEPTICISM on one of the fuses threads. Further, Audioquest, a strong advocate of wire directionality, is hardly a one man operation. One more thing, fuses aren’t marked for direction, that’s left up to the user to decide.
In fact, your argument is similar to the argument that most high end cable manufacturers cryogenically treat all their cables to lend technical sophistication and legitimacy to their products. 😀 If that’s true how do you explain the cable manufacturers who don’t advertise they Cryo their cables? Answer at 11.
I personally think it’s just a question of how competitive you as a manufacturer wish to be and how hard you want to win Best of Show.
