DS Audio DS-W3 Optical Cartridge

Cartridge Independent LED and photo-detector arrangement for the left and right channels

The new DS-W3 optical cartridge system has been optimized, by implementing an independent LED and photo-detector arrangement for the left and right channels. As a result the cartridge output voltage has greatly increased from 40mV to 70mV. The DS-W3 cartridge offers a greatly improved S/N ratio when compared to its stable mates, resulting in an even lower noise floor and far greater musical clarity.

Weight of shading plate reduced by more than 50%

The implementation of independent left and right channel LED’ s allows for the positioning of the optical system to be optimized as well as necessitating the use of a new shading plate that has been significantly reduced in size compared to our earlier designs. In addition to this reduction in size, the material used to produce the shading plate has changed from aluminium (as used in the second generation cartridges) to 99.9% pure beryllium.

Boron cantilever & Aluminum body

The DS-W3 cartridge features the combination of an boron cantilever with a line contact stylus. The cartridge body is made of aluminum and the structure has been designed in such a way as to promote maximum rigidity.
