Has anyone had trouble with speed on their tt

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?

But thanks to everyone for the thoughts. I had bought Origin Live's best tranny/motor DC200/and motor controller and had problems so I bought a second complete O.L.system and had them both turning a heavy steel Aerex flywheel. The VPI tt was updated to the super platter that is now defunct. It was driven with belts and I tweaked them for just the right tension and everything lubed and leveled and was always unhappy with my speed. My McIntosh 831MVP blu ray player with Upgrade Co mods cannot touch Expressimo's turntable and motor. Plus Mac had trouble with the transports and it took a long time to get mine back after owning it less than a year. Digital does have excellent speed and if you get a good modder like David Schulte to shield it properly you can take the jitter out of the digital system. My vinyl still bests it by a good margin.

Mosin You might be onto something about the platter being so important to speed control.
