Accuphase E-700 Integrated Amplifier
Flagship Class A integrated amplifier offering refined power, premium control, and fully balanced architecture for high-end stereo systems.
The Accuphase E-700 Integrated Amplifier represents the pinnacle of Accuphase’s Class A integrated design, combining reference-grade circuitry with the musical warmth and precision that define the brand. Built on technology developed for Accuphase’s 50th-anniversary flagship models, the E-700 delivers 35 watts per channel into 8 ohms, 70 watts into 4 ohms, and 140 watts into 2 ohms, with peak headroom up to 160 watts into 1 ohm.
The Accuphase E-700 features the advanced Balanced AAVA (Analog Vari-gain Amplifier) volume control system with ANCC (Noise and Distortion Canceling Circuit), maintaining ultra-low distortion and exceptional linearity. Its fourfold parallel push-pull MOS-FET output stage operates in pure Class A, ensuring smooth, natural sound with effortless musical flow.
From input to output, the Accuphase E-700 maintains a fully balanced signal path for the lowest possible noise floor. A massive toroidal transformer and large filter capacitors provide rock-solid power, while a damping factor of 1,000 ensures total control over even the most demanding loudspeakers.
With balanced XLR and RCA inputs, tone and balance controls, speaker selector, and upgrade slots for the DAC-60 digital input or AD-60 phono stage, the Accuphase E-700 is designed to be the heart of a world-class home audio system. Every detail, from its aluminum chassis to its precision controls, reflects Accuphase’s heritage of engineering excellence.
