The DS 003 incorporates the latest generation of optical transducer technology from the Japanese company DS Audio, and in lab tests has been proved to be built with the highest quality standard. In listening sessions, record after record not only does it further glorify the family traits of background quietness, transient vividness, detail resolution and tonal neutrality, but also have surpassed most conventional cartridges in freedom from mechanical graininess or electronic glare/haze. It is also a definite champion in imaging accuracy/stability throughout the entire audible range. More importantly, the DS 003 has such low level of measurable and perceivable distortion, the illusion of an open-reel master tape being played, or even a live event taking place in the room occurs much more often than any competitor in the similar price range. I am tempted to conclude that, this generation of optical cartridges is now capable of impressing listeners not only with abundant musical information, but also with certain amount of magical and seductive power. Strongly recommended.
