The stylus is a consumable product with a typical service life of approximately 300-400 hours. Normal wear and tear is expected over time. 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 with use, its ability to accurately track high-frequency signals in the record groove diminishes. When o details become less distinct, high frequencies degrade, and sound quality becomes dull, it may be time to replace the stylus. The stylus cantilever is made of high-quality material, providing improved rigidity and consistent sound performance.
