A tonearm is a crucial component of a turntable that holds the cartridge and stylus while playing vinyl records. Its primary function is to track the grooves of the record, converting the mechanical vibrations into electrical signals that can be amplified and heard through speakers. Tonearms come in various designs, including straight and S-shaped types, each affecting sound quality and tracking ability. The quality of a tonearm can significantly influence the overall performance of a vinyl playback system, making it an essential consideration for audiophiles and music enthusiasts.
