DS AUDIO - DS E3 Optical Cartridge

"Truly beyond price.
The DS-E3 is a revolutionary technology in historic record reproduction."
Ikuo Tsunoda, Audio Critic


The DS-E3 is a third-generation optical cartridge mechanism using the same design as DS Audio's other optical cartridges. This evolutionary analog based technology generates an analog signal via displacement of record groove modulation vs typical velocity by utilizing an optimized photo-electric conversion, allowing for optimal trackability of vinyl information without the typical pitfalls.

The DS-E3 achieves an overwhelmingly low price while inheriting the merits of the third-generation mechanism, such as higher output for a significant inprovement in Signal-to-Noise due to independent LED and PD, improved channel separation, and the use of a beryllium light shielding plate. An unbelievable entry point for beginners in the vinyl arena who haven't dedicated funds to a standard velocity based RIAA phono stage.

Aluminum Cantilever with Elliptical needle
The cantilever is made of aluminum and the needle tip is a solid elliptical needle. While adopting the third-generation optical cartridge mechanism, the channel separation is set 1db lower to improve mass production efficiency.
