Topic: Are gold-plated TRS connectors a waste of money?
I'm shopping for Neutrik TRS plugs to connect gear to my UFX analogue I/O. We all known the theory: gold plating offers good corrosion resistance but wears out quickly because gold is soft, so the general rule is "gold-plated for permanent connections, nickel-plated for things you plug and unplug frequently". That makes sense, but the TRS connectors on the UFX are all nickel-plated. Not saying nickel-plated is bad, but it makes me wonder... surely there is no benefit to be gained from using gold-plated plugs if the UFX jacks are nickel-plated, no? In other words, the weakest link would be the UFX gear would be the weakest link in terms of corrosion resistance. Besides, mixing metals may actually accelerate the corrosion process (see galvanic corrosion).
Have you guys ever experienced corrosion on nickel-plated contacts? I can imagine it being a problem if you live in South East Asia or near the sea, but usually is it a problem?
