Inheriting the essence
of the Grand Master

DS003

“The DS 003 shows emphatically how trickle-down technology benefits the customer, while maintaining a pecking order. As close as it is to the mind-boggling Grand Master, enough differences ensure that the two can co-exist: the DS 003 is the more lively of the two, the Grand Master the more subtle. That said, if you can afford a Grand Master, buy it. If you cannot, the astonishing DS 003 will still blow your mind” Ken Kessler Hi Fi News

 

DETAILS

Cartridge

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. /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. 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. 1.6 times thicker than used in the second generation cartridges

 

 

Equalizer

Changed the thickness of the circuit board and the thickness of the copper foil.

Compared to the DS002 equalizer, the thickness of the circuit board has been changed from 1.6 mm to 2.0 mm, and the thickness of the copper foil has been changed from 35µ to 70µ.In addition, the DS003 equalizer allows you to select the cutoff frequency for the low frequency range from four types, allowing you to select an output that better matches your system.

 

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. product is hand-made and quality assured by our skilled engineers.

REVIEW & AWARDS

The Abso!ute Sound - DS Audio DS 003 Optical Phono Cartridge - Read More

"The optical groove-reading system is fairly easy to explain: The intensity of a light from a miniaturized “lamp” inside the cartridge is continuously modulated by the movement of an extremely low-mass “shading plate” attached to the stylus/cantilever. As the stylus vibrates, the shading plate vibrates in sympathy, blocking varying amounts of the light coming from the lamp. This variable luminosity is then turned into variable voltages by photoreceptors and sent on to a dedicated phonostage unit, where it is equalized and boosted to line level. " - Jonathan Valin

"What we’ve got here is an optical cartridge, one that doesn’t rely on magnets and coils to generate an electrical signal, and—for the most part—it’s a total paradigm shift. There’s no coil, no magnets, and the cartridge itself is an active component! So there’s lots to go over here. Please bear with me as I go through it because it’s worth it." - Jason Thorpe

"DS Audio cartridges certainly possess a family sound. Seasoned audio enthusiasts might agree that all the various types – MM, low- and high-output MC, strain gauge, Decca/London, moving-iron, moving-flux, and in this case optical – all exhibit specific characteristics. Cantilever material and stylus profile offer some differentiation within a given range and so it is here, in part, with the new DS 003." - Ken Kessler
