A moving magnet cartridge with an Elliptical stylus designed to work with most turntables. Designed to provide easy mounting and alignment on both top mount and bottom mount headshells, and provides excellent compatibility when used in an assortment of playback systems and with a wide variety of phono preamps.
The OM Series body is manufactured from Noryl (plastic & glass compound), a lightweight material, which ensures high rigidity and freedom from resonances. 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.
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. 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 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 Series allows you to step up to better sound by simply upgrading the stylus. Depending on your preference, styli for the OM Series are easily interchanged and include: styli 3E, 5E, 10, 20, 30, 40 & 78 and D 25 M.

Is analogue better?
Vinyl is a cost-effective way to get into proper audio. Some experts argue it it gives a better experience than digital, with a lack of compression and a naturalness that’s hard to replicate.
Digital relies on a computerised interpretation of sound-waves. Turntables and records, however, maintain analogue integrity by translating these sound-waves into physical grooves and vibrations rather than 0s and 1s.
I liken turntables to coffee. They can be terrible or wonderful.
Rightly done, they'll produce a brilliant sound and last you a long time. But the bad ones sound gross and can damage your records.
It's all about materials and construction. A turntable is a mechanical instrument that needs to measure record grooves in a delicate way.
What to *avoid* in a turntable
This product page will run through what makes the Primary E such an ace deck for the money. But what shouldn't be inside a turntable is just as important as what is. Here's a summary of the things to avoid, and we've got more detail here.
Inbuilt speakers. This is baaaaad. They're small and tinny, so you'll be strangling whatever signal does come out of the record. But also the vibrations being inside the chassis create a feedback loop which goes back into your records.
A tonearm that's too short or made out of the wrong materials - this will interfere with the accuracy of what's embedded in the record. Small platters are bad too - they'll eventually warp your records due to the edge overhang.
Stylus and cartridge that put the wrong pressure on your records or are made out of bad materials. These will distort your sound and potentially damage your vinyl.
Cheaper motors that don't spin precisely in time. You'll hear higher or lower pitch in your music.
