The wide-range DC Integrated Amplifier which went back to the origin of amplifier, strove for the modification of a nakedness property, and adopted the circuitry which devoted in tone-quality serious consideration by the repetition of the audition.

Operational stability was realized not only to super-low-pass one but to the super-high region, and frequency characteristic DC-200kHz is attained.
