I think you are all getting this massively arse about face. This isn't Rega turning its hand to making limousines or Formula One cars; I can't write this without it reading like complete pretentious cobblers, but it's like buying the Platonic Form of Rega. It's not meant to be the last word in bling or massive overengineering, it's the Mitochondrial Eve of Rega turntables... all current Rega turntables derive from the Naiad. Truth is, even up until about May this year, Rega was still unsure whether this product was a product, for the same reasons you have intimated. It was a breadboard design for the RP-series developments. However, Roy had been repeatedly asked to bring the test-bed into production - "whatever the cost" - by distributors and guests who visited the factory, and by absolutely anyone who heard it at Roy's listening room.
Having been one of the lucky few who has heard it (and perhaps the only person here who's actually got some listening time on the turntable, allowing me to pass comment with something even remotely connected to an informed opinion, even though the room and the rest of the system was new to me), there is a lot of potential in the Naiad. But even up to a few weeks ago, Roy remained 'troubled' by the costs involved in making the turntable, and the fact that it is such a low-numbers device (due to the practically one-off nature of some of those parts) it will necessarily cost far more than any other Rega thing, ever. But, IIRC about 25 of those first 40 decks were a shoe-in due to pre-orders on the deck, if it ever came to fruition.
As of about March this year, it was going to be a limited run of turntables to distributors alone, but someone pointed out to Roy that all it would do is massively piss off those full-time Rega supporters who would happily chew off their arm to own anything Rega... and they do exist. So, it became the Naiad and was started to be considered to be a product that could go into strictly limited production. As to the signed editions and the first 40 serial numbers being in sequence from 1973-2013... that was my idea I'm afraid, when we visited Rega recently.
Given the market for top-end turntables, I anticipate a market of about 80-100 units all up, even at £30,000, and I think that Rega will probably sell most of those in the first 12-18 months, and then spend the next three and a half years selling the last few, because that is how high-end rolls. Yes, if it had been built like an obsidian and acrylic obstacle course, had vacuum pumps, magnetic levitation, belts made of unicorn snot and cost over £100,000 it might sell a few more, but then they would take 20 years to sell and they wouldn't have been born out of a test-bed for Rega's turntable line. And Roy would have despised it so much, it would have broken him.
