DS-E3 equalizer
New Amplification and Power Supply Circuits
In the 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.
Miniaturization is achieved by using an operational amplifier
The DS-E3 equalizer 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 1/3 the size of the DS003 equalizer.
Truly beyond price.

DS-E3 Optical Cartridge
Uses a third-generation optical cartridge mechanism
The DS-E3 uses a third-generation optical cartridge mechanism, the same design as our other products.
The DS-E3 achieves an overwhelmingly low price while inheriting the merits of the third-generation mechanism, such as higher output due to independent LED and PD, improved channel separation, and the use of a beryllium light shielding plate.
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.
Truly beyond price.

The DS-E3 is a revolutionary technology in historic record reproduction.
