SPU Meister

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.

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.
