The choice of turntable cartridge depends on several factors including your budget, the type of music you prefer, your turntable's specifications, and your overall sound quality expectations. Generally, cartridges come in two main types: Moving Magnet (MM) and Moving Coil (MC). MM cartridges are more common and affordable, offering a good balance of performance and price, making them suitable for casual listening and entry-level to mid-range turntables. MC cartridges are typically more expensive and are favoured by audiophiles for their superior sound quality and detail. Consider also the compatibility with your tonearm (whether it's standard mount or P-mount) and the type of music you listen to, as some cartridges perform better with certain genres.
