I'd like to add my two cents, I have been in constant contact with Corbyn, and she's been a great help. They've been going all over Asia touring the Roxannes so I'd give them a little slack now. And there's also the fact that they're swamped with the Roxanne orders. I'd give them some slack this time of year.
Paying over $1500 for an item shouldn't require giving them "slack". All they'd have to do is send out regular emails to their customers updating them of what is going on and giving realistic expectations of when they're going to be shipping.
I just ordered a pair of Shure SE846 from Amazon. Once they arrive if I like them I'm cancelling my JH order.
