Turntable speed accuracy

Albert, Thanks for the specifics on the TimeLine tests. That Mk 3 must be something and perhaps "best of DD breed". I'd love to hear it someday. Pity it's no longer made.

I witnessed a TimeLine demo on a DD table last weekend. The owner held an envelope 12" from the laser and yes, the spot did not move during the 30 second test. When I asked him what the result would be if he let the laser hit the wall six feet behind the table, he admitted it would not maintain its fixed position. Now that table does have speed adjustments for fine tuning, and I presume better results could be attained, though we did not spend the time. I appreciate and respect the thoroughness with which you seem to be doing your evaluations.

The remainder of your post is thorough and well reasoned, it seems to me. Thank you for summarizing the issues to clearly. It's very helpful.

Thanks Albert,
A thoroughly lucid and objective opinion........from a subjective point of view.....which is all we can really have after all?
Right Nandric? :^)

Hi Albert,

thanks for the responce inrelation to the NVS using the TimeLine.

It's great you are providing other info. too but as you mention it's your take, prefference and obviously VERY subjective.

I have heard two SP10 MK3's to date now in my own set-up and over all preffered specific belt drive tables, "all belt drives aren't buit equal" in comparison but that's for another thread.

While I was visiting Syntax last month, he checked the speed stability of his machine. The laser from the Timeline was spot-on and did not waiver...his well-tuned Micro Seiki RX-5000/RY-5500 was simply steady and consistent.

Albert, you may have already mentioned the reason, if so, I apologize for bringingtip the question again...why do you think that the NVS was not up to task? Since you are not having issues with your fabulously-modified Technics Mk 3, great; why do think you maybe having instability with the NVS? It appears that is not an issue with the quality of the mains being presented to the motor controller; otherwise, I guess that Technics Mk
3 would also have an issue...what do you think could be the issue with the NVS?

Cheers!
Alan

Albert - excellent, thoughtful response. You may now don your asbestos suit! ; - )

I think you make a couple of excellent points; namely that speed precision AND accuracy are both important. IME, individuals vary in their sensitivity to one versus the other. I also agree that while speed parameters are obviously important to turntable performance, other characteristics contribute to the overall turntable quality including immunity from internally and externally generated noise/vibration.
