World's Best Cables use their own unique 4% blend of silver solder in all their cables, and the joints are military-grade hand soldered. Like most manufacturers, they offer a 5 year warranty. Their 24k Gold Eminence jacks have an advantage over the Switchcraft counterparts. Instead of having in-line solder points which are prone to shorting out, the Eminence jacks have solder points that are almost 90 degrees apart from the cable. Moreover, the Eminence shorting prevention substrate is affixed to the inner roof of the jack's top half... keeping it snug in place.
