Da Vinci AAS Gabriel

y.s.:

Not necessarily, in fact I have this suspicion from what I heard this far, there is once again some trade-of going on here.
I have heard the 'musical' mass-platters close to what you mention (alas not with loosish string), - and very 'fast' lower-mass-platters ~ 4.5kg, that can sound a bit 'restless' even nervous like.
So Thomas, where he sees it, seems a bit unclear to me, but since he likes to 'stir the pot' he may like AND dislike both, in the fashion of a true chilled out cynic?

In the case of a ~ mass-platter (of sorts), Transrotor Z3 with a jolly tense neoprene belt, it goes as much the route pretty of a Thorens 2010 arrangement.

Then we have the 'Platine Verdier' with yet heavier platter and a rather LONG, no-stretch Kevlar? string. (Tensioning and length is up to the user - like how long is your rack space?)

If I'd have to pick between the 3, I guess I'd be still looking at the 'Verdier' rather.
Then we have the SME system, fast, dynamic --- BUT not necessarily all what you'd call a: really dynamic low register, [or] "air" in the bass line, YMMV.

Now, so we wont loose the thread subject -- where do our 2 contenders, TW & Da Vinci, fall into the scheme of things?

Note: I once tried a no-stretch string in place of a square (stretchy belt) on a RPM 9 ----> result: Plain awful...
Greetings,

Axel, ...... back to the object of this thread: in terms of both - craftsmanship and tooling - I would go for the Raven (but I don't need to....).
Both - Raven (whatever incarnation) as well as Gabriel do both desperately need a working isolation to be able to show their merits.
Putting them "hard-coded" on any solid ground/shelf, rack means simply giving (rather throwing....) away 50% of the possible performance.

As for the RPM 9 with thread.
It needs some experience to get the right "feel" (if you don't have the right equipment) as far as the thread tension goes. Too much - pretty bad. Too less - pretty bad too...
"Right" tension - pretty amazing......

And yes - I would take the Verdier any time above the two contenders.
Preferably a Verdier made prior to 1993.

Dertonarm,

Did you ever test the Verdier for stray magnetic fields above the platter that would in fact negatively impact a cartridges performance by interfering with the cartridges magnetics?

Dgad,
yes - I did. About 18 years ago. First I was suspicious about this too. The big magnetic rings relatively close to the tiny magnets inside the cartridge,....hmmm.

However, - as the tests showed (and some measurements done at the technical high school Munich) the 2 magnetic rings are embedded inside two steel "rings" which do very effectively shield the magnetic field - at least from dispensing vertically towards the platter surface.
There was no detectable interaction with the magnets in cartridges nor did the test show any induced hum.
It performed flawless with a very wide range of cartridges from Ortofon MC-5000, Supex, Koetsu, FR, Grasshopper v.d.Hul, Dynavector,Kiseki, Ikeda EMPL, SPU and Miyabi.
The Verdier is a fairly "raw" concept and was from its very beginnings as a DIY-project introduced in the late 1970ies in the french L'Audiophile-magazine. It is however a smart design which gives - proper set-up - extremely good sonic results and has some very clever design features which all do work for the better in performance (if not in looks....).

The versions built prior to 1993 are sonically better to later production.
The versions with pure magnetic bearing in the horizontal plane - no added ball.
I am referring to the La Platine Verdier only.

A permanent magnet cannot induce hum. There is no need to test it.
