DS Audio Grand Master Phono Cartridge

DS Audio's flagship optical phono cartridge, engineered to bring analog sound to another level.    The new Grand Master optical cartridge is optimized by implementing a new independent (dual mono) LED and photo-detector arrangement for the left and right channels. The cartridge output voltage has greatly increased from 40 mV to 70 mV, significantly more than traditional phono cartridges. With this dramatic increase in output, DS Audio's excellent signal to noise ratio has been furthered improved, resulting in an even lower noise floor and greater musical clarity. The new design of the Grand Master generator further reduces crosstalk, greatly improving left and right channel separation, specifically above 10 kHz.  Over 50% reduction in moving mass  With the implementation of dual mono LEDs, a new larger shading plate was engineered using 99.9% pure beryllium for optimal positioning and agility.   DS Audio succeeded in reducing the weight of this shading plate by more than 50%, from 1.5
