Turntable speed accuracy


There is another thread (about the NVS table) which has a subordinate discussion about turntable speed accuracy and different methods of checking. Some suggest using the Timeline laser, others use a strobe disk.

I assume everyone agrees that speed accuracy is of utmost importance. What is the best way to verify results? What is the most speed-accurate drive method? And is speed accuracy really the most important consideration for proper turntable design or are there some compromises with certain drive types that make others still viable?

If speed accuracy has nothing to do with sound performance but is a seriuos basic request with a design then where would you as a designer place it in order of importance if all else is managed in a design of a turntable?

In other words if the motor/s, speed controller, belt/s are not up to the job holding the speed when a record is being played would this not drastically effect what you hear?
Tony you may find Dovers record player interesting ,surely a heavy weight contender for ultra sophisticated speed control.

Henry if my memory is correct I seam to think that I read somewhere TW Acustics stated their motor speed control was designed to perform like a vintage direct drive.
Halcro Good work and thank you for your time spent on this.

I know that I am pitch sensitive and I believe it is most important perceptual feature in music.
Which is why I have never been satisfied with any of the belt drive turntables that I have owned so far.

Fascinating and of course your table would be something to experience even though I could never afford it along with associated components.
Have you now or are you planning a web site for your products?
