Audioquest manufactures cables in China for a long time (10 years?). They moved production there, cut prices and changed names of the cables to stay competitive. Python IC, for instance, became King Cobra (half of the price).
I suspect that big portion of price is not actual cost of manufacturing but R&D. I don't know if this can explain such price difference but on the other hand DH Gate doesn't give any specifications. Are they high purity silver? what type of insulation? Is it foam Polyethylene and carbon loaded partially conductive Polyethylene for negative conductors? Even if all is perfect copy of original (including patented DBS system) I would ask if DH Gate has authorization from AQ. If not, it is pretty much like buying stolen bike - some people wouldn't do it but others pretend not to know it is stolen.
