Description The 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 OMs. 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 2.5 g. An OM cartridge from Ortofon makes it possible to upgrade the performance of an entire music system very easily by upgrading the stylus.
