Hi @audphile1 Unfortunately, it was a cash transaction.
Just heard back from the seller. He does not want to offer a refund. He figures I just don't like the cable, so I can simply resell it. I told him that the problem is the cable doesn't work as it should. And therefore, I can't resell it, in good faith.
I also suggested that if I send it to Cardas and they determine it's faulty or fake, then I'd have to pursue a fraud claim. Although, that's probably not gonna bear much fruit. So I asked him again for a refund, and offered to cover the cost of return shipping. We'll see what he comes back with. My guess is he won't comply.
I'd send it to Cardas, as many have suggested, but my gut is that it's not counterfeit, but rather, old, and perhaps damaged in some way. And by the time I pay for shipping, validation, re-termination (assuming it's okay...which doesn't make sense, given its sonic signature), shipping back, duty/taxes/brokerage fees etc -- just so I can resell it -- it's doubtful if it would be worth my time.
Best, JAMES.
