Ortofon OM 5E Moving Magnet Cartridge

OM 5E Moving Magnet Cartridge, by Ortofon.

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 attached. 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.

OM 5E features an elliptical stylus that provides balanced and distortion-free playback. Elliptical diamonds are able to follow the groove oscillations more accurately than spherical diamonds due to their contoured shape. This results in better tracking and less distortion.

By adopting a wide range of replacement styli, the OM 5 Series can provide an optimum match for your home system, application and budget. In the development of OM cartridges, a major objective was to provide the music lover with the opportunity to optimize sound reproduction without having to replace the entire cartridge. Instead of being merely intended for replacement purposes following wear or damage, the OM 5 Series allows you to step up to better sound by simply upgrading the stylus.

For more than 50 years, Ortofon has been designing and manufacturing Moving Magnet cartridges. Along with their well-regarded Moving Coil cartridges, Moving Magnet models have established a good reputation among music lovers and Hi-Fi enthusiasts the world over.
