For more than 50 years, Ortofon has been designing and manufacturing Moving Magnet cartridges. Along with our well-regarded Moving Coil cartridges, Moving Magnet models have established a good reputation among music lovers and Hi-Fi enthusiasts the world over. OM 5E features 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. The OM 5 Series allows you to step up to better sound by simply upgrading the stylus. Depending on your preference, styli for the OM 5 Series are easily interchanged and include: styli 3E, 5E, 10, 20, 30, 40 & 78 and D 25 M.
