Dereneville - linear scanning of the grooves
- Thread starter Derainer
- Start date
I listened the first combination in Munich MOC 2018 with Tedeska cartridge.
Difference between the Derenville and SME was important even if on SME a more expensive cartridge was used.

Delighted to see this.
As an old bloke who worked on engineering record players in the 1970s but stopped to work in F1 racing I have found it depressing to read about "advances" on tone arms which have actually been variations on same-old, normally using static parameters for a dynamic device
This is a proper modern bit of engineering to do the right thing. I have been using a Goldmund T3f for over 20 years and this is the first arm I have seen which makes sense to me since production of the T3f stopped, and all this newer technology which wasn't available before.
Bravo! €30k looks good value compared to a lot of what I see.

Thanks for the pictures Bob.
That was in Munich at the High End show 2018
Together with Thöress Amplifiers and Tedeska Pickups it was a very successful event.
Michael Fremer also visited us on the first day. He was visibly impressed.
kind regards, Rainer

Oh, I can reassure you. It's very easy to use and really stable enough. It's all tried and tested components.
I think that some rotary tonearms are more sensitive and can fail faster.
Another good thing is that it is completely maintenance-free. There is nothing to pay attention to.
I have an older customer who can see very badly. He can no longer see the grooves on the record.
With my linear tonearm he is very happy again. And he is sure that he will not damage his vinyl.
So no reason to shy away. You can believe me. Once the tonearm is calibrated, you can't do anything wrong.

Rainer, do you visit the USA sometimes and help your customers?
Sorry if I missed that earlier.
Cheers,

I have been using a similar concept of arm but much older engineering without mishap for nearly 30 years.
This with its much more modern control system should be fine. I have plenty of pivoting arms (I was involved in the business in the 1970s) and none of them are as safe to use as this will be.
I can understand a reluctance to buy because of the cost though...
Thanks for asking, Bob.
I personally deliver each tonearm and record player to the customer.
After the calibration (12-10-7 inch, left + center) I do a little training with the customer
until everything is perfect and he is safe. That also explains the price.
After that the customer doesn't need me anymore*. Also not for changing the pickup.
*Unless he wants to share a good whisky, or a glass wine with me.

Rainer,
How do you compare your arm against Kuzma Airline and ET-2?
Agree that tangential arms have some advantages but you need to stick better to rubber free carts, like Zyx or AS/Palladian!?

Hi E.
Our LT arm is actively controlled. The ones you mentioned are passive arms.
With all these passive LT-arms the small filigree needle has to do all the work of the feed.
It has to push the masses of the tonearm and all the tubes and cables.
The cables are made very thin to reduce the resistance. However, this can lead to radio interference.
Our tonearm, on the other hand, has shielded balanced high-end audio cables with XLR connectors.
The tonearm is basically built like a rotary tonearm. The pivot point is actively guided and driven along.
The high precision distance laser monitors the 90 degree angle 100 times per second.
It permanently reports to the electronic control, which monitors the angle of rotation
always remains constant with 90°.
The filigree needle lies in the groove only with the specified support weight.
There is no lateral force at all on the groove flanks.
Please have a look at the graphic in my 2nd article.

With our principle of active linear scanning we can give the tonearm itself sufficient mass.
An MC system with low compliance can get all the information out of the groove - even the deepest bass in music.
I miss this excellent sampling of the very low frequencies in many passive LT systems.
They can't reproduce this because they have too little mass due to their construction.
I hope I was able to answer your question satisfactorily.

Thanks Rainer,
It is true that with the passive arms you might have radio interference if you do not take care on shielding etc.
On the other hand with the active arms you have a lot of active parts having impact on the arm tube and on the needle (energy transfer).
I remember the Goldmund arm, which was really insufficient. I had it and sold it.
Active arms control one aspect of the scanning but maybe also opening a handful of other issues on tracking.
How many times have we seen the Thales improving it’s design? It is always a compromise.
Nevertheless your design is very interesting.

Yeah, you're right, we know all these problems.
But we have all solved them perfectly. And it took almost five years for development.
I also wrote that in my story.
Today we are happy to present an active LT arm that plays far away from Goldmund and other LT arms.
To date we have five very satisfied customers. And there will be more.
But we only build six of these LT arms a year. And we have limited them to 24 pieces.
And once again: the operation is really child's play.
All components are also used in industry and have proven themselves many times over.
So there is no reason to shy away from it.
When the new LT arm is ready I will make a short video to show how easy it is.
You live in Munich - why don't you take a flight to Paderborn and visit me - I cordially invite you here.
I will also pick you up at the airport, if you wish. Afterwards you can honestly report to the users here.
kind regards, Rainer
Rainer,
Thanks for your invitation. I am in Paderborn from time to time, also having friends over there.
I will let you know when I am coming.
All the best

Believe me. It´s a Question of Time. This will come.or "Juke Box Adam"
For Machines who can also do this
And it will make a fresh Espresso during the Changing Procedure.
Quite impressive that video above. Some romance is missing in that industrial robotic world ...
And from 4:44 with the two humans being turned upside down and around; headache and stomachache. They need to cut down on noise too.
