At US$1,799, this DS Audio DS E3 optical phono system & preamplifier is a fair used deal compared to the typical market, sitting right at the median of US$1,799 from three recent comparable listings, well below the new retail total of roughly US$2,750 for the separate cartridge and equalizer. You’re getting the same third-generation optical tech as the E1s for less, and far below the US$5,000 all-in cost of higher-end DS optical systems like the 003.
This is a worthwhile buy because the DS E3 delivers distinctive clarity and transparency with a neutral, accurate frequency balance, making it an entry point into DS’s revered optical cartridge line. The bundled preamp/equalizer is essential since conventional phono stages won’t work with optical cartridges, and at this price you’re locking in a complete, high-performance system that’s rare to find used with the preamp included. Unless the condition is questionable or accessories are missing, this is a clean buying opportunity for enthusiasts seeking optical sound without the premium cost.
Independent perspective — not a price guarantee. Always verify condition, accessories and provenance before purchase.
# DS Audio
DS Audio is a Japanese hi-fi specialist founded in October 2013 by Tetsuaki Aoyagi, building on his father's three-decade legacy in laser optics through Digital Stream Corporation. Based in Sagamihara, Kanagawa, the brand emerged from a deliberate mission to reinvent analog playback and "create the future of analog music." This heritage in precision optics proved instrumental in developing the company's signature technology.
The brand is renowned almost exclusively for optical phono cartridges—a category in which DS Audio stands alone as the world's sole major manufacturer. Their cartridges employ proprietary LED-based optical transducers that dramatically improve upon earlier Toshiba designs, eliminating traditional stylus contact and offering exceptional longevity (approximately 50,000 usable hours). DS Audio complements these cartridges with matching phono stages and turntable accessories, maintaining a tightly focused product ecosystem.
DS Audio occupies the high-end and ultra-high-end market segment, commanding premium pricing justified by proprietary innovation and limited competition. The brand has cultivated a devoted following among analog enthusiasts and collectors worldwide, with its optical cartridges climbing to the upper echelons of audio desirability. This is unquestionably a niche boutique manufacturer, but one with genuine technological differentiation and a growing reputation for excellence in a specialized domain.
