The stylus is a wear-item with a typical service life of approximately 300-400 hours. Besides damage from improper handling, excessive tracking force, low-quality records, or unstable turntable surfaces, the lifespan of the needle tip may be reduced. As the radius of curvature of the needle tip increases over time, its ability to track high-frequency signals in the record groove diminishes. When audio details decrease, high frequencies degrade, and sound becomes increasingly dull, consider replacing the cartridge. The cantilever is constructed from high-quality material, enhancing durability and helping maintain consistent audio performance.
