@q66 @vidister My favorite is still the gold-plated Toslink cable.

Because it's become so mainstream that it's the only type of toslink cable available in some stores (I mean, stores that don't even target a particularly audiophile audience).

Gold plating is already rarely useful (if ever) for a digital connector, but Toslink is an optic fiber, often made out of plastic (and sometimes glass)! 🤣
