DS Audio DS 003 Optical Phono Cartridge

Description

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

The new DS003 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 DS003 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 aluminum
(as used in the second-generation cartridges) to 99.9% pure beryllium.

Aluminum cantilever & Aluminum body

The DS003 cartridge features the combination of an aluminum
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 DS003 utilizes internal wiring 1.6
times thicker than used in the second-generation cartridges in order to
