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?

You must be kidding me, right?

Ketchup, Well still a live are: Lurne, Kuzma, Driessen (Pluto) and Simon Yorke. To my knowledge only Lurne produced also DD TT's (Studio, Studietto) but in his own
company (Audiomeca) only belt driven TT's. It seems reasonable to think that they prefered belt drive. Lurne also published about his design phylosophy but I can't
recollect his thoughts about DD's.

There may well be, but I doubt very much they would post on an English speaking forum. Japanese? ...maybe!
Ecir38 - Thanks, you are right. I couldn't see this info on the Sutherland website so I emailed them and they confirmed that the new model puts out 8 flashes per 1.8 seconds. This gives the user eight spots to choose from. I wish they would update their rather cryptic user manual with this info. It still says one flash per rev.

Can anyone name one brand that is not Japanese, not German, and not Swiss origin that made direct-drive turntables in the 70's, 80's, and 90's before the Rockport Sirius III, which was reviewed in Stereophile in 2000? I certainly cannot think of one. So for 3 decades in the USA and UK that were dominated by Linn, there was no manufacturer making DD tables. Are audiophiles really that monogamous? That statistic is frightening, considering the two audio powerhouses in the world did not make a single direct-drive turntable in the heydays of analog!
