Paua/ Nautilus


The laws of physics dictate how moving systems operate, therefore cartridges must strictly adhere to first principles to get sublime results. In accord with these laws, the Sussurro has an incredibly low effective moving mass, resulting in vastly improved damping.

The lowered inertia means less stored energy in the moving system, so that primary resonances that normally occur all but vanish.

This moving iron design allows the required stationary magnetic parts to be rigidly held in exact position at all times. The fully shielded annealed case allows totally hum free operation, RF shielding, and extreme mechanical stability.

  • MC Preamp compatible
  • Ultra low effective moving mass resulting in superlative transient and micro detail performance
  • Telescoping Aluminum Alloy Cantilever / Selected nude Contact Line diamond stylus
  • Composite body featuring impedance matched energy transmission system

For the first time it is possible to enjoy the virtues of our low effective moving mass architecture with the finest step ups and phono preamps for truly amazing vinyl replay.
