  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?

Dear Raul - $500 for a properly functioning SP-10MKII (with PS) ?

I will be sure to contact you the next time I buy one.

For the SP10MKII the following public data is published.

Speed fluctuation by load changes: 0% within 5kg-cm.

Can someone technical explain to me what "5kg - cm" really means in laymans terms. Can I really put that much weight in that area and it will stay accurate ?

D, Syntax, Thuchan - Did or do any current BD TT manufactures publish accuracy values ?

I would think that for someone interested in a high end platter/motor setup these types of figures attract the customer.

Like when buying a car.

0 - 100km in 4.5 seconds. :^)

As a customer without ever hearing it - the published numbers are what got me curious in the first place about an SP10mkII.

Cheers
