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?

Speed Accuracy done right at Monterrey / California via thread Drive.
We have a small black hole in the wall, right behind the turntable. We guess it is a Laser burned one :-)

Dear Syntax: Well Halcro has a wider black hole in the wall, right behind the TT. This TT is a DD 400.00 Victor TT.

So not big deal what you are showing against the humble Victor or my Denon one.
It is not here at speed accuracy/stability where belongs the " secret " for a top quality level that you till today can't even imagine could exist.

Have fun.

Regards and enjoy the music,

I found a random picture of a turntable online that looks like the kind of thread drive turntable Dertonarm would make. :)

Any idea who made that?

Nice shot Hiho,
Never seen that turntable before?
Intrigued by the armpod cylinder. Seems like it may revolve for different length arms and has multi-way fixing options?

For the record Raul.....the Victor TT-81 was $300.00 but I doubt that it was able to 'burn' a hole in the wall like the TT-101 which cost the princely sum of $1500.00..........the best money spent on my system other than my speakers :^)

Hiho, that is some german manufactured tt, but I can't remember the name. It is a belt drive however.
