The stylus is a wear item, and its normal service life is approximately 300-400 hours. Damage caused by improper handling, excessive tracking force, low-quality records, or unstable turntables may shorten the lifespan of the stylus tip. As the radius of curvature of the stylus tip increases with use, its ability to track high-frequency signals in the groove diminishes. When audio details decrease, high frequencies become weaker, and sound becomes duller, it may be time to replace the cartridge. The stylus cantilever is made of high-quality material, enhancing rigidity and helping maintain consistent sound output.
