i was intrigued (or bored enough) to google this dhgate, about which i was only vaguely familiar. they're not a seller, rather they're a platform, more-or-less like ebay, for thousands of independent seller. as best as i can ascertain, the platform itself is legit, and very large--they have an escrow service to assure delivery of products, etc.--but there's no controls on the source of merchandise which the sellers sell, and the consensus is that most of it is counterfeit or gray market. there's also no meaningful recourse if a buyer gets burned on a purchase. (there's a ton of "dh scam" and other web chatter that cast aspersions on the whole enterprise). it may well be, as marakanetz states, that many buyers are perfectly happy with the stuff they get from dhgate, and that the knockoff products are just as good as the real thing, though i personally wouldn't touch it.
Don't read you'll be sorry
Just got my new Audioquest K 2 speaker cables from DH GATE yep I said it. I bought my previous Audioquest cables from my former employer [Audio Buys] Summer job pre wiring houses. Still great friends. Anyway paid their cost for a brand spanking new pair of "Bed Rock" cables I was so proud. So what I know are quote un quote real Audioquest cables just got blown away by a $380.00 total cost [shipped door to door in 6 days] pair of Audioquest k2's from DH Gate.
