I. General Information

The J.Sikora tonearms are a unipivot design that is the first to use aramid fiber for the Arm Wand. Aramid is
very light, stiff, and resistant to resonances. This makes it an ideal material for the production of the

Wand’s

conical tube. Using aramid fiber reflects

J.Sikora’s overarching philosophy of combining

unique properties of

various materials such as aluminum, bronze, cast iron, and steel to maximize vibration control and stability.
