I would say any American or European or Japanese 'Brand Name' cable, Like AQ or Cardas or Kimber sold by an eBay from China is 99% likely to be fake.
Cardas and Kimber are made in USA. AudioQuest is made in China. so some may be simply stolen factory/factory defects.
Even USA purchase of used stuff like Kimber Hero or Cardas Golden Cross may be fakes.
It is harder to fake the special covers and connectors of some cables.
Fake cables are a big problem in the used market.
Many cables new, come with a special box, or a serial number on a card. These MUST be with the cable if one even thinks of buying an expensive used cable. One can send a cable to the company to verify it is real. But if it is a fake, the company will keep it..
Cables may have ultra pure wire, or unique insulation, Stuff the fakes do not have.
I no longer buy used wires at all. Just not worth the risk.
