Sapphire cantilever with micro-ridge stylus

The micro-ridge stylus of the DS Master1 features a minimum-curvature radius and is mounted to a sapphire cantilever. The super low mass optical generator, which eliminates the need for magnets and coils as found in conventional phono cartridges, is free of ultra-sonic ringing. These features allow the Master1 to reproduce every element of musical information with stunning nuances and brilliant detail, redefining flagship-level performance.

Overwhelmingly high rigidity

Advanced Material Science was employed throughout the development phase of the DS Master1. No detail was overlooked. Over the past two years, all aspects of the design and components have been re-evaluated to ensure the highest rigidity possible in the Master1 cartridge. From its Ultra-duralumin body to its amethyst power indicator window, we have carefully selected each material and component to ensure that the DS Master1 represents a phono cartridge of the highest quality.

Dual mono circuit

The DS Master1’ s matching equalizer features expertly designed, fully discrete dual-mono analog circuits with three independent power supplies. Each channel of the Master1 equalizer has its own discrete power supply to deliver more than ample power, with the third power supply dedicated to the DS Master1 cartridge’s LED optical drive system. This solution delivers unparalleled performance.

Fully balanced XLR output

Offering a choice of outputs and low frequency response options, the DS Master1 equalizer features three sets of RCA and XLR outputs and three separate low frequency cut-off points. Each low frequency contour is accessed by its own dedicated single-ended RCA or balanced XLR output for a total of six sets of dual-mono outputs, providing ultimate flexibility.

Hand-made in Japan circuit board

Every component part used in our products is tested and evaluated by our expert Japanese technicians. In addition to using a specially printed circuit board, twist-connection of the component legs is further evidence of DS Audio’s excellent attention to detail. Each and every product is hand-made and quality assured by our skilled engineers.
