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?

Heck, around these parts a nice looking plinth can get the juices flowing. :) Toneless beating in time is not the sum and substance ('heart and soul') of music, regardless of its capacity to motivate. There is no false dichotomy of one over the other (rhythm or melody). Now ... back to the turntable accuracy dance off.
Hi Thuchan,

I do understand that your system stands in Bavaria and it is located on-speed outside of Munich :-)

Also, I like following this attitude of "but sometimes fast driving"...out on the road! :-)

Always happy listening!
Ct, "Can someone technical explain to me what "5kg - cm" really means in laymans terms."

From the SP-10 Mk2A Operating Instructions:

"If 500 tonearms of 2 g. tracking force were placed on a record at the same time the turntable would still maintain each rated speed."

If this is correct, it does seem to offer a reasonable margin. ;-)
