Ortofon SPU Meister Silver GM MKII
A Briefing on Ortofon's SPU CartridgesOrtofon’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 favorite throughout the years, both for modern and vintage high-end applications. The latest incarnation of SPU cartridges feature a wood-based integrated headshell to further reduce resonance and provide an authentic and attractive aesthetic.

Ratings & Reviews
All of the performance of the GM E II dynamic, tuneful, with tighter, more controlled bass, more extended and cleaner highs, and overall a more refined sound. A big step up from the very competent GM E II.
