Ortofon SPU Meister Silver GM MkII The SPU Meister Silver GM MkII is an SPU Moving Coil 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.
