I'd call Audio Advisor and ask them the specifics. I'm willing to bet that it's an ex-demo or returned piece, but you never know.
Kind of turns me off a bit that Audio Advisor's doing this though. It's one thing to advertise and sell as a demo or open box item, it's another thing to advertise them as factory refreshed. Nothing wrong with Spearit Sound selling refribished NAD gear, as it's NAD gear. I think Bryston's above that.
Hopefully that doesn't start a war.
