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?

That is one thing about the original Empire table that they got right- the platter and the motor mounts are not floating with respect to each other. Wow and flutter on even the first models had excellent specs. The motor on those machines are also quite powerful and have a lot of torque.

A powerful drive is really helpful to speed stability and is why the best vintage machines are still respected today.

Hi Unoear - so the Sirius is yours :^)
I have never seen one let alone heard one.
If I owned one I would never sell it - even if it meant my two 17 years olds had to pay for their own university.
FWIW - My earlier comment came from reading past posts here by members who have heard it and actually complained about some part of its sonics.
Sounds unbelievable to me. I can only assume the setup (most likely the arm?) must not have been optimal.
Cheers

I didn't count the screws on the Timeline Thuchan because I thought.......although they supply a Hex bolt with it.........someone is really saying "don't open this!" :^)

How does the Criterion stack up with the Timeline? That would be interesting to know?

Never tried the Timeline with the Criterion because the air damping asks for a record fixing knob over the spindle of the platter.

I may try without the special fixing tool.

Dear all, I'm sorry I've stop watching the forum for a few days and so, I've admit I've felt somewhat pitty for no one of you could not indentify all of my bitter posts regarding the TT which been pictured by Hiho at 11-14-11.
It is my (28000 EURO) Symphonic Line RG6 and I have it from 1996. I'm trying to sell it locally for about a year with no luck here in Greece. I don't know how to post a picture with my Pluto on it (please Chris if you have the kindness do it for me). It is not possible to convert it for other than the euro std of 230V/50Hz and it is a great challenge for me to pack it safetly so, no interest to sell it other than local pick up. I'm not satisfied by this TT and I've allready replaced it by Thorens TD124 II/Saec WE308SX. I would not comment furthermore about it as I've allready said more than enough. You can search my posts in Agon.
