quote lewm: "The stator or magnet part of the motor is actually part of the inert platter itself or is firmly mated to it."
I assume this is when it is both inert and in motion, either way how could it be any more directly-coupled than that? The principal problem with direct drive turntables when they were introduced was 'cogging' created by movement between the magnetic poles of the motor. So they reduced the problem by adding additional poles to the motor. I think around 24 was thought to be enough, however that's still 24 cogs in around 2 seconds. I can think of 1 high-end DD turntable manufacturer only(Goldmund) and one other mass-producer that has a quite romantic following (more initially with DJs) and I understand they have announced they are going to discontinue building their tables (notwithstanding the vinyl resurgence). Their romantic resale value should rise even more accordingly.
As far as rim-drives go, this is mostly a market of diy/garage builders based around 40 year old designs
rebuilding salvageable $50 (c 1960)tables. Oh, I do hear VPI offers a rim drive option on one of its pricier setups. Either way, its a wheel, directly driven by a motor and the wheel makes direct contact with the platter.
Anyway, I actually am thinking seriously about trying a KAB 1200 myself in one of my systems.
