Hopefully, you have an instruction manual for whatever turntable you
are using. Different brands and models have different ways of
adjusting tracking force. One common method is to look for a
counterweight on the tonearm at the opposite end from the cartridge
and try and adjust that to provide more or less pressure at the
cartridge end.
So what I'm doing, then, is changing the weight with which the
cartridge enters the grooves? How would this affect sibilance?
You are changing the weight with which the cartrdige bears down on the
grooves. It is important that the cartridge is always exerting a positive
force on the groove, so that it will follow the undulations of the groove.
There are dynamic forces due to the motion of the stylus as it follows the
groove, that then to allow the stylus to pull away from the groove. If the
stylus does not accurately follow the undulations of the groove, then there
will be distortion. The sibilance you hear may be distortion that is
generated by the stylus not following the undulations of the groove.
