Accuphase E-700

The E-700 is a pure Class A stereo integrated amplifier that brings together advanced design technology cultivated over 50 years and uses the latest circuitry and high-quality materials to significantly improve performance and sound quality. The preamplifier section is equipped with a ``Balanced AAVA volume control'' and the entire signal flow from the input terminal to the output terminal is completely balanced allowing for high-purity signal transmission. In order to further improve electrical performance we have optimized the component placement board pattern and ground layout and adopted our unique "ANCC" for the current-voltage conversion circuit achieving low distortion and low noise. The power amplifier section employs the latest instrumentation amplifier method has a balanced signal path and is equipped with an advanced ``MCS+'' circuit and current feedback amplification circuit to improve various characteristics. In addition by making full use of the highest grade materials circuits and pattern technology we achieve low impedance a guaranteed damping factor of 1000 and ideal drive for any speaker. Power MOS FETs are used as output elements and each channel is driven by 4 parallel push-pull pure class A operation. A powerful power supply section with a large power capacity toroidal transformer and large capacity filter capacitor achieves linear power of 35W/8Ω 70W/4Ω 140W/2Ω 160W/1Ω (music signal). Within the Class A operating range the power consumption of the power supply section is always constant and it exhibits unwavering ability to respond to changes in any input signal. "E-700" is an integrated amplifier that achieves performance and sound quality approaching that of flagship models.
