The DS Audio DS003 Optical Cartridge is an advanced optical pickup featuring channel-independent LEDs and photo-detectors that boost output voltage to 70mV for an exceptionally low noise floor and improved S/N ratio. Its optical mechanism employs a 99.9% pure beryllium shading plate with over 50% reduced mass compared to previous generations. Housed in an ultra-rigid aluminium body, the cartridge combines an aluminium cantilever with a line-contact stylus and 1.6x thicker internal wiring for reduced impedance and enhanced signal clarity.

The Japanese company DS Audio is a true pioneer in the field of modern vinyl record playback. As a specialist division of the development company Digital Stream Corporation, it brings to market unique optical phono cartridges and specialised equalisers. Unlike traditional MM and MC systems, which generate a signal through the movement of a magnet or coil within a magnetic field, DS Audio’s optical cartridges detect the movement of the stylus by measuring changes in the shadow and brightness of an infrared LED and photodiodes. As a result, there is no magnetic resistance, allowing the stylus to move freely, smoothly and with exceptional precision along the record groove. The system’s moving mass is extremely low, resulting in a radical reduction in noise, zero magnetic distortion and a clean, native analogue signal with a vast dynamic range.
DS Audio’s optical technology operates on the principle of amplitude proportionality, achieving an excellent signal-to-noise ratio, a solid bass foundation and incredible detail. The brand’s comprehensive portfolio ranges from more affordable systems right up to the absolute reference class. The company also supplies specially developed phono equalisers for its cartridges, as well as innovative accessories, including ionisers to remove static charge and stylus cleaning systems. DS Audio products are designed for discerning vinyl enthusiasts and audiophiles seeking maximum clarity, dynamics and the definitive technological solution for the analogue signal chain.
