The DS Audio DS-E3 Equalizer is a compact, entry-level phono stage designed specifically for third-generation optical cartridges. Utilizing operational amplifiers as primary gain elements, it drastically shortens the signal path and reduces component count, achieving a footprint approximately one-third the size of the DS003 equalizer. The unit features a fully symmetrical amplification circuit and a newly stabilized power supply system delivering clean voltage to the cartridge, resulting in enhanced signal clarity and faster transient response.

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.
