Direct drive doesn't require using a servomotor for speed regulation. There doesn't necessarily even have to be a feedback loop, although I don't see that as being bad.I like some technologies just because I think they are simple and elegant. I like Wankel engines. For piston engines, I like overhead cams. And I like the idea of direct drive for turntables.
Didn't stop me from using a turntable with a belt in my best sound system or a piston engine with pushrods in my hotrod car though. Sometimes the best stuff is old school. I'm even running a carburetor and points.
I guess its like the solid-state verses tube thing. Some would say that tubes are obsolete and pay them no attention. Others would have nothing but a tube amp. I think you can make really good equipment using a variety of technologies.
Sometimes the best stuff is lower tech but hand-crafted to perfection.
