All direct drives do not cog. Any non-coreless motor can cog, including belt drive tables. Also, because a belt drive is usually turning at 300rpm, multiple resonance modes are being induced into the platter. Now, I'll admit that I have yet to hear a belt drive that I like as I prefer idlers and direct drive table. I can always hear the motors in belt drive tables from several feet away at 33.3 rpm, including one very nice $40k belt drive table I have recently evaluated. I was shocked that I could hear the very very heavy motor as it spun. I can not hear my GAE or SP10 mk3 motors at 33.3 rpm even with my ear on the plinth.
The belt drives have their place I am sure but for me they simply lack drive/force, a sense of power if you will. Idlers and directs have this attribute which I am partial to.
Better direct drive including the SL1200 Mk2 also do not "hunt and seek" as Mr. Framer and others have alleged in times past. That is why it is call a Quartz -Lock. It locks to speed and adjusts when a load change is detected. All one has to do is scope (O'scope) the table and look at the resultant wave-form. Cheap tables may exhibit that undesirable behavior but even the SL1200 MK X did not behave in that manner.
Now, having made my thoughts public, I have nothing against belt drive tables other than the fact that I've never heard one that I prefer over a direct or idler. Never heard a Caliburn :)
Just wanted to comment on some things I see posted over and over and which I know to be in error.
