Direct Drive vs. Idler Drive vs. Belt drive


I'd like to know your thoughts on the strengths and weaknesses of each drive system. I can see that direct drive is more in vogue over the last few years but is it superior to the other drive systems? I've had first-hand experiences with two out of the three drive systems but looking to learn more.

I have a Garrard 301 grease in Woodsong plinth, EMT 948, and Kuzma Reference (belt/suspended). I like to think I love all my children equally. But if I had to sacrifice one it would be the Kuzma. 
Mikelavigne,

the TechDas tables do have an air cushion feature and air dampened feet. They do not have a real air bearing! You may look it up at my Caeles II report on AudioCirc.

Mikelavigne,

just look under „Air Bearing“
maybe you see one the first time 😀

Right Atmasphere, if on a "proper stand" which includes the floor and everything under it, a situation most of us have no control over. On any wood joist floor you will be in trouble. Those of us on concrete slabs are lucky. I personally do not think that level of speed stability is all that important. Like distortion in amps it becomes a numbers game. But, I do not have any prolonged experience with modern DD tables. My bias comes from the unfortunately distant past. You as an audio manufacturer get a lot more opportunity to play with this stuff than I do and I do believe I am jealous of that. My life just lead me in another direction.
What tonearm would you put on the 1200G?

thank you for that hint. i did see a picture of the bearing here;

looks very purposeful. it’s similar to what i had on my Rockport Sirius III. not sure about the TechDAS.

currently my CS Port LFT1 has an air bearing and the whole platter sits on an air film. it is a low flow low pressure design. i like it a lot.
