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.

One could argue that if they have to add so many motors, the fundamental belt drive implementation might be flawed.

Not only can you hear rumble but it also distorts everything else you woofers are doing.

I have a Rek-o-kut and it has a little rumble. It’s old and the plinth is crap. I also have 2 rebuilt and updated Garrard 401s. There is no rumble or woofer flapping on my Spendors or REL S3 sub. And piano and organ sound right.

@scar972  There's a photo on my System page. It's an aluminum light grease bearing with POM linings and ceramic ball. Made by a guy in Asia. SPH. sphBearing AT gmail com

I replaced the bearing in my 401 idler and the improvement was transformative. So much so, that anyone with an original is not hearing what the table is capable of.
