2020 update : JC Verdier La Platine

A recent encounter with a JC Verdier dealer as well as a recent Audiogon discussion thread led to the start of this thread. He was in my house updating my La Platine which had been in storage for ten years with thread and oil. While he has high regards for the deck, his newer clients nevertheless prefer a Techdas iii than an 'old' La Platine. Given the proliferation of expensive decks in the past dozen years, La Platine has become very much under-appreciated. 

It's clear to me that the influence of the La Platine is everywhere to be found. Specifically, the magnetic suspension system that was employed 30+ years ago. Even SOTA offers their newer decks with mag. lev. features. And if you read this review: https://www.callas-audio.nl/Callas%20Platine%20Mod%20Kit%20Review.pdf, the Continuum Caliburn uses the same concept, which was not acknowledged in Fremer's review, albeit with more sophisticated , and expensive, execution.

It is also clear to me that there is much misunderstanding of the workings of the La Platine. I for one have contributed to this. The motor of the La Platine, for example, has been much maligned. The thread drive is another aspect of the turntable that have been described as inferior. With regard to the motor and thread drive, I have been set straight by Chris @ct0517 and Lyubomir @lbelchev. Experimenting with the different types of silk threads, the tightness to the platter  and a renewed understanding of the soundness of the Philips motor have been rewarded with better dynamics and transparency. 

The funny thing is that during the past two years of re-engagement with audio, I have questioned ownership of every components in my arsenal except the La Platine. It has always been a keeper. I wonder if La Platine owners would contribute to celebrating this 'old' deck with tales, advice, and insights?

Cheers!

@ct0517  Yes, I agree about the ball.
Platine Verdier users have debated a lot about the advantages and disadvantages of using a steel ball. Removing it is from our point of view the best solution to preserve the turntable from noise and vibrations.

My bearing does not leak too. But it is open inverted bearing -  the oil flow very slowly to the bottom of the axle.  It's just physics.

Recharging the bearing with oil should be a monthly routine. The consumption of oil is dependent on temperature an how much the turntable is used.

oh I have tried to add oil.
Unfortunately, unlike my 993, it doesn't take much. 8^(
I'm sure it is taking a little.

I don't see a debate with the ball. It's a Vibration Resonance (VR) activity to generate a small signal. Adding in additional points of conduit is never good. The manufacturer has done everything possible to isolate, especially in the use of dissimilar materials, to control resonances. The differing materials between the platter and spindle one example most never see.

While I have been experimenting with the stock motor / thread drive , I decided to try something else. For the last 2 1/2 weeks, I switched out the stock motor with a Jasmine ( high torque?) motor and Origin Live belt. The behavior of the platter to this belt drive obviously is quite different. Platter starts and stops much faster, it’s interaction with the motor much more immediate. My initial listening impression was a more stable bass image within the soundstage. Not a dramatic difference but different enough. I deicided to keep the belt drive for two weeks. 
Three days ago I switched back again to the thread drive / stock motor. What I assumed was an improvement on the bass front with the belt drive, turned out not so dramatic. In addition, with the return of  the thread drive, the air around instruments and the sense of the venue were all that much more palpable, that much more ‘real’. While I still don’t quite understand the workings of the thread drive and braking, I can attest that it sounds better than after market belt drive.
I still believe a thread drive with a servo motor that monitors speed stability, e.g. SOTA and Roadrunner, may  be worth investigating down the road. 

A final thought on light strobe. I feel that it is a  measuring tool, like the use of a ruler for  distances, or a Fozameter for sound separation. It’s objective!  Now Lederman of SoundSmith prefers cartridges with a left / right channel differential. That’s subjective. I have no argument with someone’s listening preferences, especially when the the analog sound produced is comparable to reel- to reel.  But we ought to assume that speed stability is one of the criteria for achieving such a sound quality. If that is not the case, that speed stability doesn’t matter,  I would still like to the what the measurable
deviations were.

My turntable is a JC Verdier Nouvelle Platine, the one without the magnetic bearing, but with the same platter and motor. I have just upgraded it with the Sota Eclypse combo,and an OL belt. Speed accuracy is better (between 33,332 and 33,336) but W&F Less precise (0,08 instead of 0,06 %) I used the Analog Magik to have the figures. The issue with the motor of the Verdier is simple,you are not able to set with precision the speed. Musical results are better with The Eclipse combo.

I must admit, today is the first time I carefully read the letter from Verdier in which he explains about the braking effect at the spindle. That is an accepted method to smooth out or drown the braking effect due to stylus drag and probably does go a ways toward stabilizing speed.  Other and more "vintage" turntables did the same, including grease-bearing versions of the Garrard 301.  Verdier mentions the TD124; I was not aware that it too incorporates a brake.  Setting the brake just right is important to get the most out of it, I would imagine.  Not having owned a Verdier, I have no idea what the steel ball does; it sounds like it adds to or is integral to the mechanism of the brake.
