@imhififan , It is not ''either or'' but both (aka conjunction).
All my headshells have this ''movable 4 pin connector'' which
make azimuth as well eff. length adjustment possible. So I
don't understand persons who buy expensive headshells
without this provision. This imply all wooden headshells
because they can't ''bear'' the fastening screw.
Thanks for providing highendcity address. Those are the right
kind. AT headshells have screws threads at the under side.
For some carts very practical but not suitable for effective
length adjustment with ''short 4 pin connector''.
