The cantilever of a record cartridge, like the stylus itself, is an important part of the vibration system and necessary in order to transmit the vibrations accurately from the record to the stylus.
A variety of materials such as aluminum, sapphire, beryllium and boron are used to make cantilevers of different shapes and dimensions. The lighter and stiffer the material, the better and more accurately the cantilever can transmit vibration.
In today’s high-end cartridges, precision is also required for the materials, processing, and assembly of magnetic circuit parts as well as the suspension mechanism connected to the cantilever.
Atrotos audio is using only the best available. All the cantilevers are made in Japan.
Cantilever types and features
Ruby
Because the Ruby cantilever is very rigid, it accurately transmits the vibration of the stylus tip and, compared to metal cantilevers, a clearer sound can be enjoyed.
The diameter of the rod is 0.3mm
Boron
Large elastic modulus, high specific rigidity, and speedy sound transmission. The tip is fixed with adhesive due to fragility and limits in processability. The performance is outstanding. It is simply the best metal cantilever.
The diameter of the rod is 0.28mm
