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?

Hello Thuchan,

Congratulations, self-disclosure is good for the soul!

BTW, there is absolutely nothing wrong about being a little slow and loving it...:-)...

Always Happy Listening!

Hi Thuchan,

I do understand that your system stands in Bavaria and it is located on-speed outside of Munich :-)

Also, I like following this attitude of "but sometimes fast driving"...out on the road! :-)

Hi Albert,

I heard that you are looking to sell your NVS; are you going to still be planning to continue as a dealer for NVS and JTinn?

Mike L mentioned to me last year that he paid the same for his NVS as you did for yours...was your price around the $12k, or so, that JTinn was selling the NVS for earlier last year?

Cheers!

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!

Hi Albert,

Yes, the string-driven Big Micro Syntax machine was up to the task and, as I mentioned, spot-on; the Seiki was consistent, rotation after rotation, as represented by hole burning in the wall.

No, I did not get a chance to try a Timeline with Rockport Sirius lll while it was here last year. However; Tim Sheridan, was here late last year for a visit before I shipped the Rockport to its new home...where it joined a few other Rockport TT siblings in the UK. As you may know, Tim is the designer of the motor controller (MDA) for the Sirius lll. He tweaked the MDA to bring the speed accuracy of the Sirius lll back to his standards along with preparing the mains change and a few other items.

Cheers!

Hi Albert,

Yes, having the Rockport Sirius lll here last year was really some enlightening audio fun. It is now with Mik in the UK...he is a mad about Rockports; three lll's, and two ll's. He is also a big fan of stonebody Koetsu cartridges and the Goldfinger cartridge.

Like yourself, I do like to hear and make decisions based on what is going on in our systems.

I believe that in my case with the Rockport along with your case with the NVS, we both decided that we were not able to replicate what was presented. So, mine has found a new happy home; similarly, you are trying to find a new home for your NVS and Talea.

Albert, I have fondly followed your posts and do appreciate your desire to find the differences that work.

Cheers!
Alan
