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?

How accurate is the Timeline with its flashing laser?

supposedly time-base accuracy of 2 parts per million

Has that been measured for its accuracy ?

what happens when the batteries start to run down?

I heard about an audiophile living in Munich who usually proudly presents his very rare and expensive vintage items, including high calibre turntables. During a listening session someone stated "the sound is so slow, maybe we should check the speed accuracy". The result was 30,.. also being not very stable.

Speed was corrected to 33,33 and in the end the audiophile resisted listening to the correct speed sound. He said, I am used to the slower mode, it doesn`t matter if anything is correct. I love the sound!

Oh my god...

Best and fun only

Jtimothya, I don't think you are serious (correct me if I'm wrong), but to elaborate on my point: a great drummer playing alone can get the juices flowing with a great groove. Now, imagine a (potentially) great melody played or sung with bad rhythm. The end result can be painful.

Hello Thuchan,

Congratulations, self-disclosure is good for the soul!

BTW, there is absolutely nothing wrong about being a little slow and loving it...:-)...

Always Happy Listening!
