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.
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.
