The odyssey is similar to Odin at $3400. That AK did a promotional package that you took advantage of is not the issue here. What they did was break up a fresh pair to send you one channel. To get their pricing, they had a large run made to achieve economy of scale and ordering a single replacement now would cost them as much as odin to acquire. Of course they won't return the defective one. Replacement discounts, and you got one, always means losing the broken device so that it can't be misrepresented later. Had you sent both, it's possible they would have sent you a fresh pair for the same amount but it was going to be $1700 either way. Of course they have no interest in broken, recobbled devices on the market, tampering with their stellar reputation.
