Folks on this thread who deride the hype surrounding high-end cables are partially correct. The wire portion really doesn’t matter for digital, and hardly for analog. But connectors are vitally important for both. A cheesy cheap cable with cheesy cheap connectors might work for six months or two years, but then fretting corrosion, spring-contact fatigue and stuff like that can make for noisy and intermittent connections that can be the very devil to diagnose and can actually damage your expensive equipment.
Gold plated connectors are worth the money in the long run. Certainly, some cable manufacturers are guilty of over-hype, but to totally dismiss the possibility of there being any difference between cables is uninformed, reactionary and short-sighted.
