DS Audio DS Master3 Optical Phono Cartridge

Description

DS Master3

The successor to DS Master1, which has created the history
of DS Audio

Cartridge

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

The new Grand Master 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 Grand Master 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.

Diamond cantilever

A first for DS Audio, the Grand Master cartridge features
the combination of a square pillar diamond cantilever with a microridge stylus.
The cartridge body structure has been designed in such a way as to promote
maximum rigidity. In addition to these features, the Grand Master utilizes
internal wiring 1.6 times thicker than used in the second generation cartridges
in order to reduce impedance.
