I own Benz LP with micro ridge stylus which is about 7 years old. Benz
which used Gyger styli for years obviously changed to Namiki. The same
is the case with my EMT which used Gyger for years but not anymore.
Van den Hul own explanation is that his ''stock'' is full of old Gyger
styli. As I explained already trademark is different than patent . The
patent duration is 20 years but the owner must produce and trade
the product to get patent protection. This is obvious in case of VDH
because he deed not produce any styli. So, obviously, he stipulated
by Gyger his right to sell Gyger styli which he designed under his
own trade name. BTW he sold many more then Gyger. As I also
mentioned trade mark can be easy prolonged. Cost about 600 euro.
If you have read contribution of our ''Professor'' JCarr who is even
at higher level of knowledge than Raul HIMSELF deed no mention
Gyger at all. He agreed with my general statement about Namiki
and Ogura but explained his (aka Lyra's) exception in the sense that
they provide Ogura with boron and order special styli for their
cartridges. This thread was started with intention to find ''third
party'' because Replicant and other styli can't be from Mars but
produced by someone. The candidate are Gyger and Expert stylus.
I have different retips by Expert stylus since my friend Axel Schurholz
passed away. BTW Experts stylus is one of few who does ''stylus
only'' retip for an modest price. I was in the same position as this
French trader who hired an teacher French in order to be ''allowed''
to the French high society. He said to his teacher: ''My Gosh I speak
prose my own life without knowing that. I am very thankful to you
Professor.'' . I had also no idea that ''Paratrace'' is ''Gyger x'' despite
the fact that I own 3 of those.
