With the headshells you can tune the sound of your turntable in a very easy way.
The family of materials is graphite, but just as wood or plastic, it comes in many variants.
I have chosen a high density type, that is also oil soaked. No, I have not done it so as to get their hands dirty. It is of course finished so you can touch it without pencil marks on your fingers.
With this type I gained the most favourable sound results.
The sound is very detailed, but keeps the right timing and timbre. A real good match for top MC systems.
The design results in an extremely rigid and resonance-free headshell, which basically ensures an extended precision in sound.
