Sapphire Gramophone Needle – Double-Sided
28201
High-quality sapphire needle for precise sound reproduction
The double-sided sapphire gramophone needle is a key component of phonograph cartridges, designed for accurate sound tracking from vinyl records. Thanks to the high hardness of sapphire and its resistance to wear, it provides long-lasting performance and clear audio playback.
Compared to the single-sided variant, this reversible design allows the needle to be flipped, extending its lifespan and enabling multiple uses. This type of needle is commonly used in analog turntables, ensuring optimal contact with record grooves and enhancing playback quality.
