    MY TAKE: Wow, I'm impressed! The DS Optical Cartridge System offers some very unique and enticing attributes, along with outstanding performance. Super quiet background, very low surface noise and detailed yet utterly smooth rendition. The associated preamp/equalizer. Very highly recommended. - Galen Carol

     

    How Does It Work? –

    Unlike conventional phono cartridges which employ an electromagnetic generator (a coil positioned within a magnetic field in the case of a moving coil design), Japan’s Digital Stream Corp. uses their vast background in optical systems to re-imagine the phono cartridge using state of the art optical technology. In the DS 002 an infrared LED and optical sensor interpolate the subtle movements of the stylus/cantilever – a unique design that eliminates a number of drawbacks found in a conventional electromagnet design.
     


     

    Forty Years in the Making –

    It has been over 40 years since the first optical cartridge was introduced by Toshiba. Though a number of attempts have been made, the concept of an optical cartridge was never fully realized. It took the technical background in precision optics of DS Audio to bring the concept to fruition.
     

    Who is DS Audio? –

    DS Audio is a newly formed audio business group within Digital Stream Corporation, a company involved in the precision laser optical industry for over 25 years. The company’s high-precision disc inspection systems are used worldwide and their 95% market share in this area is testament to their quality.

    Besides working in the precision measurements by Laser optics, DSC has explored unique applications of laser technology such as PC input devices, gaming devices. The optical mouse, for example, was co-developed by Microsoft and Digital Stream Corporation. It has changed the world. DSC has received the Outstanding Engineering Excellence designation from Microsoft and was recognized for their work by Japan’s Ministry of Economy, Trade and Industry.
     

    The DS 002 -

    The DS 002 System consists of the DS 002 Optical Cartridge and the companion Preamp/Equalizer.

    Featuring an aluminum cantilever and classic Shibata stylus, the DS 002’s optical screen is positioned closer to the stylus–a breakthrough in phono cartridge design allowing for more accurate reading of the information within the record groove.

    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. The DS 002’s optical screen is placed near the stylus tip, together with a newly developed wire-suspension system to hold the cantilever. The new position of the optical screen is a breakthrough in phono cartridge design, providing a much more accurate reading of the groove information and contributing to clearer sound reproduction.

    Notably, the cantilever is more precisely positioned within the newly developed wire-suspension system in the DS 002. This new structure provides a highly accurate and precise pivot point for the cantilever, increasing channel separation to reproduce the most accurate stereo image.
     

    REVIEWS:
     

    Mono&Stereo: "In contrast to moving-magnet (MM) and moving-coil (MC) cartridges that work on the principle of electromagnetic induction, an optical cartridge uses a beam of light to read stylus/cantilever movement. The advantage of this system is twofold: it makes the cartridge much lighter and more agile, while also completely eliminating the frictional force caused by magnets and coils and the resulting influence on stylus/cantilever movement.

    "A further key advantage lies in the cartridge’s output. In conventional MM and MC designs, the output signal depends on the velocity at which a tiny magnet or coil moves in an electromagnetic field. At lower frequencies the magnet or coil moves slowly so the output signal is small, while at higher frequencies it moves more quickly and so the output signal is disproportionately large – hence the need for equalization. In contrast, in an optical cartridge the output signal depends on the distance that the styles moves, so there are no disparities between high and low frequencies. Therefore no equalization is required (other than RIAA curve correction) and low frequency reproduction is much enhanced, since an optical cartridge can theoretically detect signals as low as 1Hz. 

    "The resulting sound has delicacy, subtlety, natural warmth and a deep richness. Most important, it is stunningly real, capturing all of the miniscule yet critical details that make a musical performance come to life." - 2017

     

    The Absolute Sound: “[The DS 002] simply has to be heard to be believed.” -Jonathan Valin

     

    The Absolute Sound: Rated among the top 5 most significant analog introductions at CES 2017 by Julie Mullins

     

    The Audio Beat: "DS Audio showed a new and lower-priced optical cartridge and phono stage, the DS 002 (top two products, $5000 for the cartridge and preamplifier/equalizer). The DS 002 promises to bring the advantages of optical cartridge design within the reach of a greater number of audiophiles. An optical cartridge uses a beam of light to detect cantilever movement, rather than relying on an electrical signal generated by magnets and coils. This is claimed to produce a signal of greater purity. Based on the success of the much more expensive DS Master 1 that  has so impressed audio writers, Aki Aoyagi developed a less expensive design. However, the DS 002 is no budget product -- it is built to a very high standard." - CES 2017
