Motor Controller ugrade for Raven One Turntable

So the question still arises, how bad can the stock motor controller be that a replacement is "nothing short of astounding". And shame on TW if the stock controller is that bad on a table costing that much. since the only thing a motor is supposed to do is turn at a consistent speed, an astounding improvement is only possible if the stock motor controller didnt do that.

I am not arguing that maintaining a constant speed of the platter will not result in improved sound. I am arguing that any decent turntable of that expense should come stock with a motor and controller that does that basic function.

Hi Elinor,

how can this be? The controller just controls the motor or motors depending on which table you have.

The motor/motors have a belt attached to the pully and then the belt goes around the platter of the table.

Can anyone explain, to me it must be something to do with speed stability.

It's the modern LP12. No matter what you do, you will never reach an end.

It sounds like it should be classified as a recall and a replacement instead of an "upgrade."

I find "nothing short of astounding" an astonishing statement. I can't argue with what you and your friends are hearing but I'm curious about the reasons and if the improvement is really so pronounced. Could it have to do with noise, connection to the AC grid etc that is a difference between AC and battery powered equipment? Or is it really just speed accuracy? If it is the latter, then I agree with the "recall and a replacement instead of an upgrade" comment. Something must be wrong with the stock AC-1 motor controller though that never really got noticed in all of the glowing reviews of that table.
