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!

The sensor would be placed on the underside of the aluminum alloy platter which overhangs the magnets by about 4cm. The actual magnet sensor is approximately 5mm. If it is placed close to the edge of the platter, then there would be a 3.5cm clearance from the two La Platine magnets. This  may be enough to avoid any disturbances, but it really has not been tested. 


@xdr wrote about his experience with the Eclipse on the La Nouvelle, the baby brother / sister of the La Platine. The Nouvelle does not use magnetic repulsion on the platter, so his application of the Eclipse motor had no problems. 

Keep in mind that, at least for the Phoenix Engineering gear, the progenitor of the Eclipse system, the distance between the magnet and the Hall sensor, when the magnet passes over the sensor, is optimally one-eighth of an inch.  That’s about 3mm. If what you describe would permit that close spacing without exposing the sensor or the magnet to the considerable field strength of the magnets that support the platter or if the sensor is impervious to that magnetic field, then fine.

The more I look at the La Platine, the more I think you are correct about the incompatibility of the Eclipse drive system with it. 
I doubt if SOTA would provide a definitive answer. It would be good to hear from someone who has tried.

I do think SOTA would be forthcoming if they have the information. No harm in asking. On the question of whether the magnetic field per se would be a problem you might directly consult Bill Carlin of Phoenix Engineering. He’s a good guy, and he’s always been responsive.

You can run the basic Sota Eclipse motor and controller ( $975 ) without the Roadrunner feedback system and it will still be a significant upgrade from the Verdier motor.

Furthermore - lewm's point is probably a red herring - the monitor under the platter is unlikely to be affected by the magnets which are inboard from the platter edge. I'd put money on it, in which case you could run the Roadrunner feedback as well.
