First, I wanted to let everybody know (if you don't already) that the wonderful site "Welcome at Direct Drive" is accessable again through a new link, which is:
http://www.oocities.org/de/bc1a69/index_eng.htmlI wanted to expand a bit on Mmakshak's remarks, because they hint at something that seems to be a recurring event in the world of audio: namely that changes in the market often cause the curtailment in developing certain kinds of equipment/technologies that wind up on the back burner, sometimes for years! One such is the direct drive turntable. The belt drive took over the market because the inexpensive-to-produce version of the belt drive TT, like the original AR for example, sounded way better than the inexpensive-to-produce version of anything else. And both DD and idler drive TT's suffered from this situation -- with consumer DD's in particular getting a reputation for lousy performance -- which they deserved ;--) This is not to say that you couldn't find excellent DD's at the time, particularly from Japan, but none of them were what I would call 'consumer' products, and the companies that made them, particularly the Japanese, made a whole range of other products, and so eventually stopped developing DD's because the market wouldn't support entry-level (i.e., profitable) models. That's just the nature of free-market capitalism. But a whole generation of audio hobbyists were never exposed to DD's for that reason, and what they did hear, is that they sucked! Never mind that records themselves continued to be mastered on DD cutting lathes, hmmm . . . .
As a general rule in mechanical engineering design, 'simple is better' IF one can pull it off in the actual product! With renewed interest in vinyl comes a renewed interest in TT's; and as always, new offerings start with the "Neiman-Marcus" models. But with today's advances in materials, electronic control, and manufacturing techniques, it won't be long before a $500 DD turntable hits the market that will provide the obvious benefits of this elegant solution to record spinning. My 2 cents.
