Ortofon SPU Meister Silver GM MK I
The SPU Meister Silver GM MKII is an SPU Moving Coil (MC) cartridge that has been improved on coil winding material, stylus and magnet.
The cartridge has been outfitted with high purity multi-conductor 6 – Nines silver wire (of a purity of 99,9999 %) for a more open and revealing high end presentation.
The nude elliptical stylus tip mass has been decreased by a factor of more than 50%, resulting in increased tracking ability and reproduction of microdynamic detail.
The generator system has been revised produce a slightly higher output to ensure compatibility with a wider range of moving coil transformers and active MC preamplifiers.

Ortofon’s SPU cartridges continue the tradition of the first ever Moving Coil cartridges as originally engineered by Mr. Robert Gudmandsen and produced by Ortofon in the late 1950s. Praised for their refined linearity and full body, these cartridges have remained a favourite throughout the years, both for modern and vintage high-end applications. This year we decided to give our SPU fans around the world an opportunity to get a collection of the four most famous SPUs, each of them being a very special collector's item.
