The suspension system is an important aspect of a stylus assembly. Pfanstiehl and EVG have the same design as each other but differ from the Shure originals and JICO which are more refined.
Of the few times I've encountered sibilance, it was due to either too low tracking force or to a mismatch of stylus to tone-arm.
The
Shure 3X stylus tracks between 2.5 and 3.5 grams so is better suited to medium mass tone-arms. The M75ED with a
N75ED stylus should track between .75 and 1.5 grams which should be used in low mass tone-arms with low friction bearings.
If your tone-arm likes the
3X stylus, then I would suggest a
N75EJ stylus for the M75ED cartridge body
