Ortofon OM Scratch White Single Cartridge Mount



Ortofon Optimum Match (OM) cartridges match most tonearms perfectly. If your tonearm has a standard headshell or a cartridge mount, then step up to optimal sound reproduction with OM’s. A glance at anyone of these cartridges will reveal Ortofon’s answer to perfect tonearm matching. Ingeniously tucked into the top of the mounting bracket is a tiny, removable weight-plate.

  • If your tonearm is an standard tonearm, just leave the weight-plate.
  • If your tonearm is one of the low mass types, then simply remove the weight. The mass of your OM cartridge is now a mere 2.5g.

An OM cartridge from Ortofon makes it possible to upgrade the performance of an entire music system very easily by upgrading the stylus. We offer a wide range of replacement styli for OM cartridges. With the OM cartridge you instantly hear the improvement: music you’ve heard many times takes on new dimensions.

High output and maximum scratch performance guaranteed
