Ortofon Super OM 10 OM Single HiFi Elliptical Stylus Listening Cartridge

The Super OM cartridges have been designed on the basis of their OM lightweight system with three major improvements:

• 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.
• Additionally, a new technique was developed and applied: slit less than 1 mm dia. hollow pole pins, thus significantly reducing eddy current losses caused by magnetic hysteresis. This sophisticated technology extends the frequency range and improves phase linearity.
• Thirdly OM Super cartridge body is manufactured from a Noryl (plastic & glass compound) which ensures high rigidity, and freedom from resonances.

All Super OM models have the same body, construction and magnetic circurity. The only difference is the interchangeable stylus unit.
