OM 5S
The OM 5S features Spherical stylus, robust and economic solution for play back of vinyl records.
If your tonearm has a standard headshell or a cartridge mount, then step up to optimal sound reproduction with OMs. A glance at any one 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.

Styli types and interchangeability
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.
Features
The series is the lowest-mass range of moving magnet cartridges offered by Ortofon.
The OM cartridges bodies have been designed to provide easy mounting and alignment on both top mount and bottom mount headshells.
The OM 5 Series provides excellent compatibility when used in an assortment of playback systems and with a wide variety of phono preamps.
By means of computer simulations it has been possible to define the natural pivot point of the system with unprecedented accuracy while achieving an optimum oscillation balance. The result: improved linearity, higher channel separation, and reduced distortion.
OM Super cartridges models have split pole PINs which reduces magnetic losses at the treble end. This technology extends the frequency range and improves phase linearity.
The OM Super 5 cartridge body is manufactured from a Noryl (plastic & glass compound), which ensures high rigidity and freedom from resonances.
