The stylus is a consumable product with a typical service life of approximately 300-400 hours. Besides damage from improper handling, excessive tracking force, low-quality records, and unstable turntable conditions can reduce the lifespan of the stylus tip. As the radius of curvature of the stylus tip increases with wear, its ability to track high-frequency signals in the groove diminishes. When o details decrease, high frequencies degrade and sound becomes duller, indicating the need for replacement. The stylus cantilever is made of high-quality material, enhancing durability and helping maintain consistent o performance.
