The E-800S is our flagship model that incorporates the full breadth of Accuphase's accumulated knowledge on integrated amplifiers. The preamplifier section incorporates a Balanced AAVA type volume control, while the power amp stage relies on an instrumentation amplifier principle and six-fold parallel push-pull configuration using power MOS-FETs driven in Class A, driving any loudspeakers to higher dimensions of sound. Enjoy the blissful acoustic space provided during playback with the E-800S.

Positioning and Preamplifier Excellence

Positioned as the new flagship model above the E-650, the Accuphase E-800S integrates cutting-edge technology with meticulous craftsmanship to redefine the standards of integrated amplification. The preamplifier section boasts the impeccable Balanced AAVA type volume control, ensuring precise volume adjustment without signal degradation or impedance fluctuations. Operating seamlessly as a simple and smart system, the E-800S delivers acoustic excellence that resonates with the very essence of the music.

Vintage Design and Unparalleled Power

Exuding an aura of solid luxury, the E-800S features a lavish champagne gold front panel that dynamically changes its appearance with the viewing angle. The power amplification stage harnesses a formidable six-fold parallel push-pull configuration of power MOS-FETs driven in pure Class A, delivering impeccable power with linear progression for both channels. With capabilities of 50 watts into 8 ohms, 100 watts into 4 ohms, and 200 watts into 2 ohms, the amplifier ensures an immersive listening experience, even supplying 300 watts into 1 ohm for music signals.

Optimized Stability and Enhanced Sensory Experience

Designed for optimum stability, the E-800S's power supply circuitry features a massive high-efficiency toroidal transformer and two large 60,000 μF filtering capacitors, ensuring a stable current supply at all times. The amplifier's high-accuracy, high-rigidity volume sensor construction guarantees silky smooth operation, while the Balanced AAVA type volume control maintains high signal-to-noise ratio and low total harmonic distortion throughout the volume range. Additionally, features such as Balanced Remote Sensing and MOS-FET switches contribute to a damping factor of 1000, allowing every loudspeaker to unleash its full musical potential with superb motion control.
