I want to replace the original spherical stylus on my JVC Z-1S cartridge with an elliptical stylus. Jico list two different ellipiptical types, the DT-Z1EB for US$45.00 https://goo.gl/D8Ha78 and the DT-Z1E for US$33.00.https://goo.gl/w4HXzz I cannot find any explanation of the difference between the two. The Shibata stylus, DT-Z1 . https://goo.gl/kev3o7 . is listed for US$133.00. and the spherical stylus DT-Z1S is listed for US$43.00 https://goo.gl/GRNSEg. Can anyone enlighten me as to the difference between the Z1E and the Z1EB?
