MC A95 set-up and maintenance

As with any cartridge, setup is absolutely crucial in order to ensure the best sound reproduction capabilities. Although there are many valid paradigms that exist with regard to cartridge setup, Ortofon does not endorse a specific methodology and encourages users to explore the options as suggested by their high end audio dealer, including professional setup.

In addition to alignment, consideration must be made to adjust azimuth, anti-skating and VTA in order to maximize the potential performance of any high end cartridge.

With a complex stylus shape like the Replicant 100, there must be special attention paid to positioning the diamond in the groove.

The Stylus Rake Angle (SRA - see figure) is very important to the performance of the Replicant 100 stylus, and the long contact surface (the sharp edge) of the diamond should be almost perpendicular to the record surface when viewed from the side.  The angle between the record surface and the cantilever is close to 23 degrees when SRA is 90 degrees.

A perfect starting point is to set the tonearm parallel to the record surface and to use the recommended tracking force. The contact surface will be close to perpendicular to the record surface with this setting. The SRA can now gradually and carefully be changed be adjusting VTF and, if necessary, the tonearm height. The target should be an SRA around 92 degrees, determined by the listening experience. In other words, the point of the stylus should point slightly towards the tonearm base.

In order to attain maximum channel separation, it may be possible to adjust the azimuth. Should the cartridge not be perfectly perpendicular to the record’s surface, the tonearm or headshell may require to be tilted a few degrees.

Correct azimuth is established by observing the reflected image of the 2 parallel cartridge front lines. The cartridge’s front lines must form a straight line with the reflected lines. A flat mirror may also be used to facilitate this process.


There are 4 sets of screws included for mounting the cartridge to your tonearm. It is of great importance to choose the correct length of screws when mounting the cartridge.  Using too long screws may stop the screws inside the cartridge resulting in insufficient mounting in the headshell. The choice of screw length depends on the thickness of the headshell, and a maximum of 2.5mm free screw length under the headshell.
Mount the cartridge loosely to the headshell during this procedure.
