This was spotted recently. It looks rather similar to a Devialet Phantom. Indeed, the specifications, the terminology relating to the technology used, and the user reviews, are all copied from Devialet sources. Very naughty!

It is very cheap though, although I suspect it might not quite match the performance of the genuine Devialet product. In fact, I think there is a good chance that it will be utterly worthless rubbish. Anyone fancy trying one?
