We sell a stereo phono cartridge that uses a revolutionary new design.

The cross ring method reduces the major fault of a normal cartridge

It merges the centre point of the left and right coils by making the left and right coils cross over each other, thus enhancing the ability to regenerate truthfully all the musical signals of the LP. In this way, I was able to cancel most of the causes of distortion in vinyl reproduction.

There are generally 2 major problems in a conventional phono cartridge design. The conventional phono cartridge installs a square iron core attached to a cantilever and winds up a coil around the iron core. It also installs a wire in the centre of the iron core, and it is fixed through a rubber damper in the yoke.

Therefore the movement point is located in the rubber damper on the outside of the coil.

Those methods of generating electrical signals are known as the magnetic induction type, in that they use a core of iron so that movement is separated from the coil. As any piece of iron that is put in a magnetic field is strongly attracted to the magnet, it is not ideal for free or correct movement.

In addition, the movement point is vague because the wire is a bending part. The vague fulcrum cannot convey the movement of the stylus tip to the coil precisely.

And so a cross ring method was devised.

The cross ring method has overcome the biggest flaw of conventional phono cartridge design. The cross ring method synchronizes the centre point of the coil for both left and right channels, and enables correct reproduction by ensuring a clear movement point in the centre. In addition, I can change an iron core into resin because the movement is in the coil. It reduces the influence of the magnetic force and thus enables better freedom of movement.
