Accuphase

E-800

The E-800 is the flagship of Accuphase’s integrated range and almost floored us when we first heard it. This is a seriously impressive amplifier.

A wholly new full Class A amplifier with 50W into 8 ohms – equating to a far, far larger Class AB amplifier meaning it will drive even the most demanding loudspeakers with ease and with a performance to rival high quality separates. Accuphase’s proprietary Balanced AAVA volume control eliminates outside noise and gives an unsurpassed signal/noise ratio. And there are two modular slots for Accuphase’s optional DAC and phono boards to be added (each sold separately).

Please get in touch for pricing information.

The E-800 is positioned above the E-650 as the new flagship model in the integrated amplifier line up of Accuphase. The preamplifier section features the impeccable Balanced AAVA type volume control, while the power amplifier section is configured as an instrumentation amplifier using a six-fold parallel push-pull configuration of power MOS-FETs driven in pure Class A.

The resulting quality is on a par with high-class separate type amplifiers. Operating as a simple and smart system, the E-800 realizes acoustic excellence that reaches to the very heart of the music.

Accuphase E-800 integrated amplifier

Ultra-Massive Pure Class-A Precision Integrated Stereo Amplifier
Combining cutting-edge technology with carefully selected materials of superb quality, the E-800 exudes an aura of solid luxury, with a lavish champagne gold front panel that changes its look depending on the viewing angle, and bar graph meters that delicately reflect the rhythm of the music.

Balanced AAVA type volume control
AAVA performs volume adjustment by making use of a combination of 16 current signals with different magnitude, thereby eliminating signal degradation and impedance fluctuations and maintaining high S/N ratio and low THD over the entire volume range. In the Balanced AAVA implementation of the E-800, two AAVA circuits are driven in a fully balanced configuration with a superior capability to eliminate external noise.

High-accuracy, high-rigidity volume sensor construction
The volume sensor mechanism developed by Accuphase in-house is built from a single massive aluminium block extruded and finished with utmost precision and complemented by other substantial materials, to ensure a silky smooth operation feel.

Formidable power amplification stage
The power amplification circuitry mounted directly on a large heat sink employs a six-fold parallel push-pull configuration of power MOS-FETs driven in Class A. Two identical units arranged on the left and right sides of the chassis deliver impeccable power in a linear progression for the two channels: 50 watts into 8 ohms, 100 watts into 4 ohms, and 200 watts into 2 ohms. The amplifier can even supply 300 watts into 1 ohm (music signals).

High damping factor brings out the full musical potential of loudspeakers
Features such as Balanced Remote Sensing and MOS-FET switches help to realize a damping factor of 1000. Superb motion control lets every loudspeaker perform at its very best.

Power supply circuitry designed for optimum stability
The strong power supply with massive high-efficiency toroidal transformer and
two large 60,000 μF filtering capacitors ensures a stable current supply at all times.
