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?

I suppose using a strobe disk and the Timeline laser then comparing the results. I don't lose much sleep over it...I use a strobe disk and that is good enough.
I almost bought the timeline. Glad I didn't. using a Fluke digital multimeter is a more accurate way to set your speed, rather than trying to look at a laser being somewhat stationary on a wall. Use a test record at 1000Hz and connecting the Fluke to the output of the phono stage. For 45 rpm, the same 1000 Hz tone should read 1.35k Hz. The Fluke cost about $125.00.
