DS Audio is a Japanese high-end audio manufacturer renowned for pioneering optical phono cartridge technology. Founded by Tetsuaki Aoyagi, the company introduced its first optical cartridge in 2013, revolutionizing analog playback by replacing traditional moving magnet (MM) and moving coil (MC) designs with an optical system that converts stylus movement into an electrical signal via LED and photodetector arrays. This approach eliminates electromagnetic interference, resulting in a lower noise floor and enhanced clarity.

DS Audio’s product line includes models such as the DS-W3, DS-003, and DS-E3, each offering varying levels of performance and affordability. Their cartridges are paired with custom-designed equalizers to ensure optimal signal processing. Handcrafted in Japan, DS Audio’s products are celebrated for their innovation, precision, and contribution to the resurgence of analog vinyl playback.
