MFI is not adding hundreds of dollars to the price. So everyone that thinks this would be half as expensive without i-device compatibility can rest easy. That is not the reason it is $600. You are probably looking at $30, on the high side for a license fee. This, of course, does not include R&D but it certainly isn't going to cost $300.
Yes. I'm fairly confident Apple actually controls (or sells directly) the chips that can interface with the lightning connector and enable direct digital access. There are already $100 lightning compatible docks out there, so there's no way MFI is driving the price to where it is.
That being said, I'm heavily interested in this product, and eager to hear about people pairing amperiors with it as those are my cans. I'm just not paying $600. Maybe Amazon will run a $200 miracle deal like they did for the original VAMP one year near Christmas. Then, I'm a buyer.
