DS Audio DS E3 Optical Cartridge and Phonostage System
The DS E3 uses DS Audio’s third-generation optical cartridge mechanism, and brings this high-performance technology to a lower price. This new mechanism offers higher output due to independent LED and PD, improved channel separation, and the use of a beryllium light shielding plate. The cantilever is made of aluminum and the stylus tip is a solid elliptical.
The DS E3 equalizer has a balanced amplification circuit, and the voltage supplied to the cartridge has been stabilized to achieve a clearer and faster sound. It uses an operational amplifier as the amplifying element to minimize the signal path, thereby greatly reducing the number of components and achieving a smaller size. As a result, the DS E3 equalizer is about a third of the size of the DS 003 equalizer.
