Light, when it strikes a crystal, scatters irregularly depending on the form of the crystal. This effect may be compared to that of sound spreading out when it meets an object. The design of the SP1000 represents the properties of mineral crystals as a metaphor for the lightness and melody of music. It juxtaposes the unchanging tenacity of stainless steel and a crystalline structure. The crown wheel provides a high-level of precision and style, and the combined push and turn functions allow the user to operate on/off and volume control just with a thumb.
