Ortofon OM-5E

Optimal fit and sound reproduction
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 a 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.

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.
