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 stylus tip wears and the radius of curvature increases, its ability to accurately track high-frequency signals in the record groove diminishes. When o details decrease, high frequencies become less clear and sound quality becomes duller, indicating it may be time to replace the stylus. The stylus body is constructed from high-quality materials to enhance durability and maintain consistent sound performance. Output voltage: 4.2 mV. Frequency response: 20 Hz - 20 kHz.
