Ortofon SPU Classic N Moving Coil Cartridge

Ortofon SPU Classic N Cartridge

The Ortofon SPU Classic N delivers the renowned SPU sound in a more flexible format, designed for use with traditional detachable headshells. Retaining the same sonic character as the SPU Classic GM series, this version allows enthusiasts to pair the cartridge with their preferred headshell or restore vintage SPU setups with authentic performance.

Known for its rich, full-bodied presentation, the SPU Classic N offers a smooth and natural sound with excellent musical flow. Its Nude Spherical stylus provides stable tracking and a forgiving nature, making it particularly well-suited to a wide range of vinyl, including older recordings.

Built using high-purity copper (OFC) coil wire and a low internal impedance design, the cartridge ensures clean signal transmission and strong dynamic expression, delivering the classic SPU listening experience.
