The stylus is a consumable product with a normal service life of approximately 300-400 hours. Damage caused by improper handling, excessive tracking force, low-quality records, or unstable turntable surfaces may reduce the lifespan of the stylus tip. As the radius of curvature of the stylus tip increases over time, its ability to track high-frequency signals in the groove diminishes. When audio details decrease, high frequencies become weaker and sound quality becomes increasingly dull, indicating the need for replacement. The stylus cantilever is made of high-quality material, enhancing rigidity and helping maintain consistent sound output.
