No, wrong.  At the start, the Nad owner had never heard of Micromega, and was still less impressed that it was French.  As far as he knew it was treated with the utmost suspicion, he had no idea what he was supposed to be hearing, and he expected his NAD to walk it.  Only when he took it home did he come to think it was so much better than his NAD.

If he'd been relying on the DBL test he'd never have known as the difference didn't show up noticeably.  Like I said, the DBL was useless in that instance.
