Hi DT...,
am I correct in assuming the 'Platine Verdier' does NOT use a motor controller, and therefore relying on belt slip/creep, platter mass, and controlled bearing friction to 'cancel' the effects of cogging?

Hi Axel,
before we go back to 1.class school:
Do you know what a motor has to do?
To fight a battle?

Trying to "controll" a heavy platter in motion with 33 1/3 rpm by a "motor" is a nice try. You have a constant "war" between the inertia of the platter and the torque and regulation of the motor.
I am sure we will have several protagonists for this principle here on Audiogon and in the "audiophile" community.
But we will find no protagonists for this principle among technical engineers.
Why ?
Well - obvious reasons, once it is given a serious and undogmatic view.
Direct coupling with quartz or whatever controlled high torque and precise motor giving the "pace" will always work quite well with low mass (= low inertia) platter.
Never against inertia.
We would then look at constant "war" with lots of tiny speed changes and everything but really constant revolution.

Well,
1. Klasse or not. If I read the response it'd tell me that "Platine Verdier" can not work as a top tt should work, because it is at constant "war" with the -constant- bearing friction... hm,?!?

Hey, I guess I'm not ready for this engineering-101 type of analysis yet. Something tells me this is more opinion then knowledge based analysis :-)

One fact to be considered: motors (most? all?) in order to perform correctly/steadily - AC to make sure, since DC is all over the place due to other issues, need to operate AGAINST some sort of load, the more constant the better.

This would completely contradict this almost 'free-wheeling' notion that I seem to hear by Syntax.
Thomas, were did you obtain your engineering degree? In the 2. Klasse then?
Greetings,

Well, it can be a endless discussion when you don't know what you hear. Most today "like" something or they read an "article/review" in a magazine, save 3-4 sentences from it and after a while they are transformed into "experience/knowledge".
Sometimes I wonder (no, wrong, I stopped that) how many Audiophiles think, what a Designer does is perfect. Ultimate. Lots are able to make enough money to buy expensive things (but only with a good discount of course/review "winner"), but on the other side they have absolutely no idea what these units are doing. And they are not seriously interested in that.
And even in the next life these discussions will go on...
One way to avoid it, is to try to visit audiophiles and listen to their Systems, sooner or later you will hear differences...the only decision you have to make then is:
- Do I "like" it or not...
- Is it right or wrong....
"In the kingdom of the blind, the one-eyed man is king"
You know, these 3 sentences...
