“If you see AudioQuest-branded products being sold for “too-good-to-be-true” prices, the chances are very good that the products are counterfeit. Be particularly wary of AudioQuest-branded cables being offered for unusually low prices from China and Hong Kong, especially on auction or bid sites.
AudioQuest cannot ensure the authenticity of any product purchased from any unauthorized AudioQuest dealer. If purchasing from a marketplace, such as Amazon or eBay, please verify that the seller is authorized.
