Product Description
The DS Audio DS-W3 optical cartridge system has been optimised 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.
The implementation of independent left and right channel LED’ s allows for the positioning of the optical system to be optimised 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.
The DS-W3 cartridge features the combination of an boron cantilever with a line contact stylus. The cartridge body is made by aluminium and the structure has been designed in such a way as to promote maximum rigidity. In addition to these features, the DS-W3 utilises internal wiring 1.6 times thicker than used in the second generation cartridges in order to reduce impedance.
Compared to the DS-W2 equaliser (phono stage), the thickness of the circuit board has been changed from 1.6mm to 2.0mm, and the thickness of the copper foil has been changed from 35µ to 70µ. Components are also optimised for third-generation cartridges. In addition, the DS-W3 phono stage has four different low-frequency outputs to choose from. It has both unbalanced and balanced outputs, so you can choose the output that best matches your system.
