The LS10 features a nude Shibata stylus, the most famous member of the “line contact” styli family. Unlike cheaper stylus shapes (spherical, conical, elliptical), the vertical tracking force (VTF) is spread along a wider area, and therefore wears slower.
In addition, the VTF of the LS10 MC Cartridge is only 1.6g, so the pressure on both the record and the stylus is kept at minimum.
The LS10 MC Cartridge stylus lifespan ranges from 2,000 to 3,000 hours.
In other words, the LS10 stylus lifespan ranges from 3 to 4 years if you listen to records 2 hours every single day.
