Yes Jurij,
here we are at a point. You can build and measure, or build and listen. You definitely need experience, time and discipline to recognise and document empirical progress. Since I work most of the time to earn money, I don't have the opportunity to do slow empirical research. I borrow ideas, combine them and let myself be surprised.
The fact that Ipe and Panzerholz/Delignit have particularly good damping has been established by others. Korf has carried out extensive measurements on tonearms, for which I am very grateful.
As long as there is no comprehensive physical world view for tonearms, we can make do with Newton, Korf and Bryan, and of course with our intuition.
For me there was also a Russian who experimentally determined the drag of pickups in his living room and Ledermann who propagates cactus needles for pickups, and of course...

Shipbuilding engineer specialising in vibrations, Döhmann who researches record players, Richard who has rethought the tonearm, everyone who thinks through and designs the world...
With best regards
Arndt
