perfect, thank you for the pictures!
the Jelco and the Koetsu gold headshell are exactly the same, apart of the used headshell wiring. So I am going to try more of those
I know , that Thomas Schick tried a FR64s without spring. This is a well known tuning for the old Rega RB300 tonearms.
I have to say, that I do understand , why Fidelity Research have chosen a spring to give the tracking force. The Tracking force is independent from outer influence.
So I like the FR64s , as he is. I tried to mix counterweight tracking force and spring tracking force, and yes, you can here a difference, even without putting the spring out, but at the moment I like the standard FR64s and Ikeda 407 set up more.
I very much appreciate your feedback on this.
Your fine tuning is very impressive. I think we can all take a leaf out of your book, because I noticed that many of your modifications do not cost the earth (unlike the cartridges ) but the small changes you have tried clearly make a fundamental difference - perhaps by way of analogy it is like focusing a camera or getting the right depth of field for a photo that you are taking.
I look forward to reading further contributions on this thread
