The DS Audio DS-E3 optical cartridge & equaliser package is a newcomer to 2024 and achieves an overwhelmingly low price, and inherits the merits of the third-generation optical cartridge mechanism. The DS-E3 benefits from a higher output due to independent LED and PD. Improved channel separation between the left and right channels, and the use of a beryllium light shielding plate also help in raising the performance bar.

Aluminium cantilever with elliptical needle
The cantilever is made of aluminium 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.

New Amplification and Power Supply Circuits
In the DS Audio DS-E3 equalizer, the amplification circuit has been made symmetrical, and the voltage supplied to the cartridge has been stabilized to achieve a clearer and faster sound.

Miniaturisation is achieved by using an operational amplifier
The DS Audio DS-E3 equalizer uses an operational amplifier as the amplifying element to minimise the signal path, thereby greatly reducing the number of components and achieving a smaller size. As a result, the DS Audio DS-E3 equalizer is about 1/3 the size of the DS-003 equalizer.
