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 Halcro: I could listen to you reading the phone book and find it gripping. You speak with a deliberateness and cadence of several philosophy professors I know. Put differently, you're the John Gielgud of the audio world.

Dear Raul: If one has built a turntable than which none greater can be conceived, then there's no need to listen to others, except as a form of idle amusement.

I tried it on a "DD" SP10 MK2 and it was off, no way to correct like the MK3 offers speed adjustments so the owner has to send it in.

Not what I wanted to read. I hate this thread.

Seriously: did the built-in strobe of that particular sp10 show that it was holding speed? And the timeline showed differently?

Thanks, Dev. I was just joking, but your post does move me closer to getting a timeline just to satisfy my curiosity.

And when I'm unhappy with the results (I pessimistically predict), I'll wish I had Lewm's skills or at least easy access to someone with similar skills.
