The DS Audio DS-003 optical cartridge & equaliser package is a completely new design, based upon the third generation of DS Audio’ s optical cartridge. It features a comprehensively re-designed optical system that provides a number of improvements and benefits.

The new DS Audio DS-003 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. 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-003 cartridge offers a greatly improved signal to noise 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 DS003 cartridge has made it possible to eliminate crosstalk, greatly improving left and right channel separation (in particular the high frequency separation has improved by1 0dB in comparison to its DS Audio forebears).

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.

As a result of this, DS have succeeded in reducing the weight of the shading plate by more than 50%, from 1.56mg to 0.74 mg. This is less than 1/10th of the mass when compared to the core and coil system found in a typical MC (moving coil) cartridge and further improves one of the key advantages of DS Audio’ s optical cartridge technology, which is an incredibly low effective mass.

The DS Audio DS-003 cartridge features the combination of aluminium cantilever with a line contact stylus. The cartridge is made by aluminium and the body structure has been designed in such a way as to promote maximum rigidity. In addition to these features, the DS-003 utilizes internal wiring 1.6 times thicker than used in the second generation cartridges in order to reduce impedance
