Hi Ben:
While direct drive turntables have an awful lot going for them (my recent experience with a Technics SL1210 only reinforced this view), they have one distinct disadvantage. In order to recuperate the huge capitol outlay required to design, implement and tool up for a good quality Direct-Drive motor unit you need to sell several thousand units per month.
Unfortunately most high end, specialist audio turntable manufacturers can only dream of these sorts of production volumes. The world market for audiophile record decks is just not big enough to support such a design project as a main stream audio product. This is where the belt drive principal becomes attractive, simple off the shelf technology that is easily adapted to fit the required application. A cynical view perhaps, but a realistic one all the same. Back in the eighties large organizations such as Technics Matsushita, JVC, Sony, Denon etc had large R&D departments and an R&D budget that would pay the national debt of some modern nations. This sort of operation could easily develop a complex direct drive system that worked very well, was cost effective to manufacture and was extremely reliable. There are many decks which are better examples of this technology and are still function today, when was the last time you have to change a belt on your D-D deck?
There are always exceptions of course and like a previous poster has mentioned the grand prix audio deck comes to mind (how deep are your pockets?), the Terres deck is also available. The Terres units are still very expensive and as I understand it Terres is more aimed at the DIY kit builders rather than the “Turnkey operation” type consumer.
However; all is not entirely lost - the DJ market is much bigger than the specialist audiophile market and this is one area where manufactures can support the production costs with sufficient sales volumes to make it all fiscally viable. Manufacturers such as Gemini, Vestax, and Numark and of coarse Technics and Audio-Technica all produce direct drive models. The last two companies produce products that have become iconic in the DJ industry. Unfortunately for music lovers most of the budget DJ decks offer very poor audio performance and can easily be bettered by a Rega or a Project Turntable. On the other hand, the Technics deck, whether you hate it or love it, also performs very well as an audiophile deck and still makes a very strong case the adoption of the direct drive technology. The little heavy weight Technics has high torque, low noise and an incredible pitch stability that I am yet to hear from any belt drive deck. You can use it straight out of the box and get very good performance or you can go for an all out assault and Pimp up the deck with a Rega or SME arm. You can also add some sexy sqidgy feet and get some very good results.
It will be interesting to see where this thread goes.
