Typically a lot of this stuff is A stock. The dealer is not allowed to officially discount many of these brands, so by calling it B stock and saying it may be a demo(like there are 50 units of demos on Audio Advisor) or a return or the cardboard box got dinged up, or some other excuse, they are then allowed to sell brand new stuff at a discount.
I bought a Nad integrated that was listed as a "display" model, and it turned out to be BNIB.
