  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.
