The Mono CG 25 Di MkII is an SPU-style Moving Coil cartridge with a spherical stylus profile, for the playback of early 25 µm mono recordings. The CG 25 Di MkII provides an authentic method of playing back these early vinyl recordings with a remarkable level of sonic accuracy.
This cartridge features a 1.5mV output, which makes it suitable for use with a variety of medium-gain moving coil transformers. Ortofon ST-M25 moving coil transformer is designed exclusively for the SPU Mono CG 25 Di MkII.
