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 by aluminum and the structure has been designed in such a way as to promote maximum rigidity. In addition to these features, the DS-W3 utilizes internal wiring 1.6 times thicker than used in the second generation cartridges in order to
Equalizer
Changed the thickness of the circuit board and the thickness of the copper foil.
Compared to the DS-W2 equalizer, the thickness of the circuit board has been changed from 1.6 mm to 2.0 mm, and the thickness of the copper foil has been changed from 35µ to 70µ.Components are also optimized for third-generation cartridges.In addition, the DS-W3 equalizer has four different low-frequency outputs to choose from. The DS-W3 equalizer has both unbalanced and balanced outputs, so you can choose the output that best matches your system.
Hand-made in Japan circuit board
Every component part used in our products is tested and evaluated by our expert Japanese technicians.
In addition to using a specially printed circuit board, twist-connection of the component legs is further evidence of DS Audio’ s excellent attention to detail.
Each and every product is hand-made and quality assured by our skilled engineers.
