Stylus size of Zero MONO $2250
0.7mil is suitable for reissue monaural LP and a monaural LP of after 1960.
1.0mil is suitable for the monaural LP of a deep groove of the first press of the 1950s.
However, both styli can trace the monaural LP of all generations without a problem. When you listen to the monaural LP of all generations, we recommend 0.7mil.
When you listen to a monaural LP of the first press of the 1950s mainly, we recommend 1.0mil
