Confirmed? By who? By the same guy who told you they were using genuine Oyaide plugs (which they obviously aren't)? By a photograph? Gee, that's not hard to fake. With all due respect Dan, it sounds like you are trying awfully hard to justify your purchase and convince yourself that these are awesome sight-unseen, when all appearances indicate you are being scammed.
By the way the AC-11 is named that way because it uses 11 gauge conductor. I thought this guy said these used 9 gauge? Also, the HT cable has two shields and tech flex over the wire, so why would they print the product info directly on the wire when it will never be seen? All indications are that this guy is scamming you. Even if what he says is true, he is breaking all kinds of laws by taking someone else's product and repackaging it under his own name.
I'm kind of baffled, really. You started a thread asking for recommendations for "the best mains cable on the planet" and got some good recommendations. But you ignore all those and go for some cheap Chinese knockoffs on ebay, and then spend this entire thread trying to convince yourself that you got "the deal of the century" when all indications are that this is a complete scam.
