Hi Ben,
If the person concerned was, Geoff, the owner of Acoustica (whom I know well), I'm a little surprised, as he's usually switched on enough to know that's not how to treat your potential customers. Btw, the Ferrari could well have been his, as he loves his sports cars!
Since I gave up on Naim (and indeed most currently produced hi-fi equipment), I no longer attend 'hi-fi shows' that are designed simply to promote a particular dealer's product range, in this case that of Acoustica.
However, I'm surprised that the sounds heard by visitors weren't better, as he used to know what he was doing.
Marco.
