Moerch tonearms:

In spite of the slender appearance, the Moerch tonearms have an amazing mechanical strength and stability. They are the result of the best precision mechanics, the finest craftsmanship, and realize technical and tonal claims without compromise.

What has been archived with the Moerch tonearms enables the cartridge to accomplish its task with extraordinary motional ease while maintaining a very high degree of stability.

The proof of their superiority lies in the listening! The Moerch arm have received high acclaim from both critics and skeptics, simply because their sonic superiority can be easily demonstrated.
