DS Audio DS-002 Optical Cartridge

World beating optical cartridge technology

Using vibration system of the same design as DS Master 1 and DS-W2 DS002 has a wire suspension mechanism which is the same design as DS Master 1 and DS-W 2 By implementing it, you realize high channel separation and stable music playback. Moreover, by arranging the position of the slit at the position close to the needle point, it is possible to retrieve information with higher freshness.

Aluminum Cantilever with Shibata stylus

Like the more expensive DS Audio cartridges, the DS 002 cartridge body is machined from aluminum and echoes their distinctive design for best optical performance. The DS 002 features an aluminum cantilever and classic Shibata stylus to accurately reproduce the music recorded on the vinyl record album.

Enhanced power supply circuit

When designing the DS 002, we carefully evaluated each component of the preamp/equalizer. The updated power supply is a key part in the new design. To ensure a high-quality power source for the preamp/equalizer, ten 33000μF capacitors are used, providing effortless power for the highest level of sound quality.

Add shield mechanism

For outstanding signal-to-noise performance, we have incorporated a special shielding structure in the preamp/equalizer design of the DS 002. This shield both isolates internal noise from the power supply while also blocking external RF and other environmental noise. The shield is 1.5mm thick and covers the entire transformer, which ensures the best signal-to-noise performance of the DS 002 preamp/equalizer.

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.

Benefits of Optical cartridge design;

Many audiophiles will remember Optical cartridges from the 1970’s. The performance of these was hailed as a radical step forwards at the time, with reviewer comments, ‘Pure, like mountain dew, yet strong like a waterfall’. Unfortunately optic technology in the 1970s had many flaws, issues with heat and signal-to-noise ratio meant that with the dawn of Compact Disc and the digital era, these products disappeared from the market – although still revered in audiophile circles. Now, 40 years later, the massive improvements in optic technology have allowed DS Audio to completely redesigned the Optical cartridge for the 21st century.

Whereas MM & MC cartridges rely on magnets and coils to generate the electrical signal, the Optical cartridge uses a beam of light to detect cantilever movement, making the cartridge much lighter, and more agile. This also removes the magnetic field inside the cartridge caused by the coils & magnets in conventional cartridge designs, and it’s subsequent influence on cantilever movement.

Faraday’s law of induction governs the design and operation of both MM and MC cartridges. As a result, both designs are subject to Lenz’s law. In audio terms, Lenz’s law states that the movement of the coil and/or magnet will produce a frictional force that affects the movement of the cantilever and hence the stylus, such that exact stylus vibration can never be reproduced by an MM or MC cartridge system. DS Audio’s optical system, on the other hand, has absolutely no effect on the vibration of the stylus/cantilever system.

Another benefit of the Optical cartridge design is the output from the cartridge itself. Whereas conventional MM & MC designs rely on ‘velocity-proportional method’, in which, the output signal depends on how fast a tiny magnet (or a tiny coil in MC) moves in the magnetic field. At lower frequencies, the magnet moves slowly in the magnetic field, so the resulted output signal level is very small. Whereas at high frequencies, the magnet moves faster, so that the output signal becomes un-proportionally large. This means MM or MC cartridges require equalisation between high and low frequencies.

In contrast the Optical cartridge system uses the ‘amplitude-proportional method’ in which, the output signal depends on how much distance the stylus moves, without the huge disparity between high & low output frequencies seen in MM and MC cartridge design. It results in no equalisation being necessary in the output signal except for RIAA curve correction. This is especially important when it comes to low frequency reproduction, as the Optical cartridge design can theoretically detect signals as low as 1Hz, as it does not rely on the speed of cartridge movement which dictates MM & MC cartridge output declines 6db/octave.
