Features

Original Parts

Silver Output Transformers

Rich and direct sound is obtained with using pure silver winding and multi-layer, multi-compartment structure.
Winding are all done by skillful technician hands using pure silver wires. It is one of the most important procedure to keep the graceful and dignity sound of 211.
We also applied special insulating materials in considering its high voltage operation.

Silver Capacitors

Silver capacitor which use pure silver foil as electrode.
It is specially designed to prevent the potential oscillation with the foil, which can easily generate muddy sound when lignal surge from low to high level.
All silver foil capacitors are Audio Note hand made.

Original Silver wire "SSW"

All conductor materials are pure silver. In order to supress the unwanted vibrations, natural silk is used and twisted around the silver conductor. It works as an insulating layer between the silver wires and the exterior PVC jacket.
