The DS-W3 cartridge is a completely new design. The third generation of DS Audio’ s optical cartridge features a comprehensively re-designed optical system that provides the following improvements and benefits:
We have further developed the optical cartridge system by implementing independent LED’ s and photo-detectors (PD’ s) for the left and right channels. The result is that the cartridge output voltage is dramatically increased from 40mV to 70mV (a 75% increase) and channel separation is greatly improved 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. Despite this dramatic increase in output, the excellent signal to noise ratio that DS Audio optical cartridges are renowned for has not been compromised. In fact, quite the opposite is true. 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.In addition to this, the new independent design of the DS-W3 cartridge has made it possible to eliminate crosstalk, greatly improving left and right channel separation (in particular the high frequency separation has improved by10dB in comparison to its DS Audio forebears.
