Ortofon SPU Mono CG 25 DI MK II Moving Coil Cartridge and Headshell

Ortofon CG 25 DI MKII Mono Cartridge

The Ortofon CG 25 DI MKII is designed to deliver an authentic playback experience for early mono vinyl recordings. Built with a focus on historical accuracy, it captures the character and tonal balance of original pressings while maintaining a high level of sonic precision.

With a higher output of 1.5mV, the CG 25 DI MKII is well-suited for use with a wide range of medium-gain moving coil transformers, making it easier to integrate into traditional analogue systems. Its spherical stylus with a larger 25µm radius is specifically optimised for early mono records, ensuring correct groove contact and minimising wear.

The cartridge body is constructed from a ground wood and resin composite, contributing to a natural tonal character and effective vibration control. Combined with high-purity OFC copper coil wire, it delivers a warm, stable, and highly musical presentation that suits vintage recordings perfectly.
