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

The new Master 3 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 dramatically increased from 40mV to 70mV. The Master 3 cartridge offers a greatly improved S/N ratio compared to its stablemates, resulting in an even lower noise floor and far greater musical clarity.

The weight of the shading plate is reduced by more than 50%

The implementation of independent left and right channel LEDs 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 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 Master 3 cartridge features the combination of a square pillar diamond cantilever with a Micro Ridge stylus. The cartridge body structure has been designed in such a way as to promote maximum rigidity. In addition to these features, the Master 3 utilizes internal wiring 1.6 times thicker than used in the second-generation cartridges in order to reduce impedance.
