Ortofon SPU Meister

The original SPU model, engineered by Mr. Robert Gudmandsen in 1959, introduced low coil impedance concept. As a basis for reproducing superb high frequencies, this concept has been improved and refined in the decades since.

In 1992 the Ortofon SPU Meister was introduced to celebrate Mr. Robert Gudmandsen’s 50th anniversary working at Ortofon.

The new features for this cartridge, again fully respecting the original concept, involved a wooden box of noble tree - a dedication from Mr. Gudmandsen to the owner of the cartridge. An important new technical data was a raise in output of about 75%, by introducing the Neodymium magnetic circuit. Further the very pure 7-Nines copper was now used for the armature windings.

A key SPU feature is an integrated headshell, designed to mount directly into classic tonearms with detachable headshells - tonearms such as the SME 3009 and 3012, and other tonearms with similar "universal" tonearm mounts. Quite simply, there is no finer complement to a classic tonearm with a detachable headshell than an Ortofon SPU.

SPU Meister features Mr. Robert Gudmandsen signature printed in both A and G-models.
