Accuphase E-700 Integrated Amplifier

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 circuits 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 fully balanced, allowing for high-purity signal transmission. In order to further improve electrical performance, the parts arrangement, board pattern and earth layout have been optimized, and the original ANCC has been adopted for the current-voltage conversion circuit, achieving low distortion and low noise. The power amplifier section adopts the latest instrumentation amplifier method, with balanced signal transmission, and is equipped with an evolved MCS+ circuit and current feedback amplifier circuit to improve various characteristics. In addition, by making full use of the highest grade materials and circuit/pattern technology, it achieves low impedance, a guaranteed damping factor of 1000, and ideal driving of any speaker. The output element uses a power MOS FET, and is driven by 4 parallel push-pull pure class A operation per channel. A powerful power supply section with a high-power capacity toroidal transformer and large-capacity filter capacitor achieves linear power of 35W/8Ω, 70W/4Ω, 140W/2Ω, and 160W/1Ω (music signal). Within the class A operating range, the power consumption of the power supply section is always constant, and it demonstrates unwavering capabilities in response to changes in any input signal. The ``E-700'' is an integrated amplifier that achieves performance and sound quality approaching that of flagship models.
