The Cobalt Blue uses the Microline tip stylus possessing ideal curvature of 80μm contact surface against the record groove. This contact surface achieved a superior reproduction characteristic. Cobalt Blue has been created to naturally reproduce the sound cut on the record.Ultra-precise Sapphire pipe material has been introduced for the cantilever. The remarkable hardness of the sapphire will help reduce distortions and is also superb in the transmission of high speed vibration to create an increasingly clear sound.
