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?

Dear Thuchan, For at least someone who looks even better
than 'us' (the Connery twins) a real suprise to show off with his behind.

Davide 256, 'the average stylus pressure is 1.5 gm.,etc.' I was always wondering about this 'drag issue' more in particular because of the 'vulnerable' stylus cantilever combo. But as a non-technical guy I was not brave enough to say something although I asked the question how this 'vulnerable thing' can cause such problems? Well I was dismissed but not convinced. I still have this 'picture' of an elephant (the platter) and the mouse (the stylus) in my mind. BTW 'my elephant' is 8 kgr.

Hiho, According to me this is a Brinkmann TT . Probable made for Burmester himself because of the colour. However I have no idea why Burmester is so fond of white colour. I also have no idea why Dertonarm posted such a criptic answer because he must be familiar with this TT.

Halcro, I have no intention at all to burn holes anywhere near my Kuzma. BTW I start my Kuzma manualy in such a way that the speed is perfect from the first groove on. The effect is less wear for the stylus as well for the motors (there are two in my Kuzma,you know ).

Adult persons watching the laser spot on the wall instead of listening to the music. This hobby really become some kind of 'decadent bourgeous inclination' as Lenin would
call it.
Dear Daniel, While Marx is your countryman I refuse to believe that my German friends are 'petty bourgeous'. On the contrary you are all the world citezens with some peculiar hobby. However 'love makes blind' is a Dutch proverb. Not easy to choose among the social rules between so many countries btw.

Regards,

Dear Lew, If you keep quoting all kinds of prowerbs attributing them to Shakespeare there is of course the chance that you may be right sometimes. BTW if it is the case that love makes blind then probable other people were also capable to discovere this truth. Only for the so called intellectual property it is relevant who wrote what first.

Hi Geoch, To my knowledge Symphonic line produces amps not
turntables. So it may be possible that Brinkmann produced
this TT for Symphonic line? To me this TT looks like a Brinkmann and should be more easy to sell as a Brinkmann. There is much more in 'a name' than Shakespeare thought.
Hi Geoch, May I suggest the German sites : www.ebay.de and
www.audio-markt.de. Your TT and the tonearm are familiar
in Germany and the Germans are the only reach people in Europe at present. You should sell both apart and , considering the postage cost for items above 20 kgr., restrict the delivery of your TT to E.Union. If you need help with German you are welcome.

Regards,
Dear Thuchan, With all your gear (past and present) you of course have much more experience with selling than I. But I have much more time to watch the 'markets' mentioned. Ebay.de is different than audio-markt.de . The latest one
is more suitable for the items with an 'fixed price' in mind ,the former if one has a vaque idea about the price. The listing time is also different: 10 days versus 1 month
min. Ebay.com is more problematic for his TT because of
the postage cost and transport outside of Europe. But like you I also prefer ebay.de. In casu however it is about Geoch and the question what may be the best solution for his problem.

Geoch, Since Brinkmann was employee by Symphonic line it may be the case that he designed this TT? To me your TT looks like an Brinkmann TT.

Regards,
Dear Thuchan, Our German friends are obviously searching for the new or added preconditions which are yet not known.
If they were known and technicaly solvable then probable
there would be no or less problems with those damn TT's.

Dear Halcro, 'but the way many are discussing ...strobes (versus) Timeline...symply leaves me open-mouthed.'
You are suggesting the lack of intellect while it is about simple psychology. A phenomenon which can be observed in nearly any thread.

Dear Swampwalker, 'Our' Lew is a scientist so no wonder he
use what Wittgenstein called 'scientific grammar'. I would prefer 'indicative statements' above 'declarative' but in any case the 'truth valued ' statments are presupposed. I believe that thinking about different drive systems involves a 'paradigm shift' but not a 'revolutionary' advance in technology. If there were a real revolutionary advances in the technology all TT's designs would use this technology. Otherwise the producers of the 'old technology' TT's would obviously speculate about possible 'sentimental buyers'.

Dear Lew, I know your opinion about Lurne for some time but
Goldmund thought obviously otherwise when they hired him
as a TT designer. I am not sure if he designed the Goldmund
Reference but well that he designed the Studio which is
a DD kind and also the F3 linear arm. The DD motor was not a problem in Europe . He used the Papst motor first and JVC latter. He is still in business btw.As you also know Dual produced two very interesting DD motors but sold many more belt drives. Dual is now back in buseness but they don't produce any DD turntables at present. The reason is probable the pessimistic market expectation.
However I also mentioned Kuzma, Driessen and Yorke but you
obviously prefered not to comment on them. Considering the
prices for their TT's one can hardly argue that the production cost is the reason for their avoidance of DD kind.

Regards,
Ketchup, Well still a live are: Lurne, Kuzma, Driessen (Pluto) and Simon Yorke. To my knowledge only Lurne produced also DD TT's (Studio, Studietto) but in his own
company (Audiomeca) only belt driven TT's. It seems reasonable to think that they prefered belt drive. Lurne also published about his design phylosophy but I can't
recollect his thoughts about DD's.

Dear Geoch, I agree totally with your 'whealty assumption'
reg. the ''exclusive TT's''. The prices are 'astronomical' but obviously not economical. Ie those are not easy to sell. So your pressuposed 'whealthy victims' are probable very scarce kind of the human kind. I do believe that we in this forum are crazy but within the reasonable bondaries. Not a merrit of our psychology but of our means. I see that you are very well informed about those 'exclusive babys'. I never heard about George Bernard btw.

Dear Lew, I had no idea that you can be also charming. I was 'programmed' to expect mainly critical remarks from you. Thanks for your comment about my Kuzma. But before my Kuzma I owned the Audiomeca J 1 . They are very similar qua design philosophy so it may be the case that Kuzma 'borrowed' some ideas from Lurne.
