It was inspired by the(47 Labs) RS Labs RS-A1 tonearm. Here's the text on the website via Google Translate:



I'm not sure any of these work at all as tonearms. Apparently this is just one big experiment and we never saw the final product as can be seen in this series pictures in historical context: What disappointment!

Can this last one work ?

I am also puzzled by the swinguing headshells you posted earlier. Can they improve tracking and reduce distortion ?

Regards

That's a loaded question. Please go back to earlier posts to explore more. The RS Labs examples are not intended to correct offset angles or to reduce tracking error so it's really not about tangency. But it is intended to reduce skating force.

Check here: www.sakurasystems.com/products/rsa-1.html

The tonearms that are intended be tangent can be examined in posts about the Thales tonearm and its theories. If you have time, go through the entire thread.

I allready read about the Thales tonearm that I had the oportunity to see and listen to in Krefeld during tha AAA show last october. I works ok but is very complicated.

I was puzzled about the head shell contraptions but you made it very clear now.

Thank you so much.

I think I included the link with the simplified answer. Here's a more elaborate piece: www.sakurasystems.com/articles/rs-a1.html

Thank you directdriver.

Now I see the point in using a high pivot

More nice pictures of Thales Simplicity tonearm. I think I like this arm even more than the flagship model.
