Has anyone had trouble with speed on their tt

Yes from a new $17,000.00 table purchase back in 2008, after complaints a new motor controller was sent to me which the manufactured called , an upgraded motor controller.
Just a poorly designed controller in the first place and the new one wasn't much better.
My ears were telling me there still were problems with this table however mentioning this on the happy owners group I hurt sensitive egos and was called names, really the joke is on them.

Most turntables of "repute" are not withing very good limits. When you hear a real stable one you realize that. The OP and Syntax are not wrong.

And all DC tables, something that is coming back to be more popular, have servo circuits, and all of them hunt, easily audible when you finally hear something that does not drift and hunt, and easily measurable.

Modern economics in high end audio: give the absolute least you can, don't think of serviceability, get the sale at all cost.

Yup 2 TTWeights TT would not keep accurate speed as told by a Timeline device!

Why not just get a speed control? That's what they're made for.

Well, Syntax, you might be right. I have Expressimo Audio and it is working great as it checks its speed 500 times per revolution and corrects the speed if there is any drag instantly. If it ever needs tweaking at all, a laptop plugs in via USB and it can be calibrated to a strobe to the tenth of a rpm. TTW also has a motor system that has favorable review I have read. Brian of Expressimo also uses very precise machining and a great ceramic bearing on his turntables and they are leveled and balanced precisely. what system do you use?
