It is the Integrated Amplifier which inherited the thought of POA-S1.

The large current type magnification element UHC MOS is adopted as a magnification element.
Current supply capability is improved a bipolar transistor and more than equivalent, and UHC MOS serves as an element which the sound quality merit of MOS FET also has.
Furthermore, in order to pull out the capability of this element to the maximum extent, the cascode bootstrap system is adopted,Ideal load to the electric power magnification stage was realized, simple and straight composition is realized, and the sauce resistance which was the cause which soils sound quality is also eliminated taking advantage of the stability of UHC MOS.

Since the Oide power is acquired with low power supply voltage by adoption of a BTL circuit, adoption of the device excellent in sound is possible.
Moreover, full separation of the ground circuit and speaker output current used as a standard of operation was carried out, and more nearly quality sound quality is realized.

excelling in a chassis at the damped-oscillation characteristic -- electromagnetism -- the "sand casting" of the nonmagnetic material in which highly precise processing which distortion does not generate easily is possible is adopted. Furthermore, by unifying a chassis and a radiator, the thorough high rigidity and absent-resonance-izing are realized.
Moreover, it is fixing to a sand casting chassis directly, and the core of a transformer and the sintered alloy insulator are also pursuing to the limit of vibrationproofing structure.

The newly developed NEW inverted sigma balance circuit corresponding to both the inputs of a balance input and a normal input is carried, the individual conversion circuit in an input stage and a voltage magnification stage is made unnecessary, and it has become the balance direct design which can do an input for the balance power amplifier of BTL composition direct.

Equalizer amplifier has adopted the exclusive constant-voltage power source of two-step composition.
Since a circuit and a power source can be completely intercepted by turning OFF an EQ Power switch when not using a Phono input, the influence of the sound quality on line-in, such as CD, is cancelable.

Since simple & straight-ization of a signal course is put into practice, a pre out, a main in terminal, tone control, a filter, a loudness, muting, and a headphone jack are not carried.
