CLASS-A INTEGRATED STEREO AMPLIFIER

The E-800 is positioned above the E-650 as the new flagship model in the integrated amplifier lineup from Accuphase. The preamplifier section features the impeccably 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 the very heart of the music. The E-800 comes with two option slots for the Accuphase 'Option Boards,' such as the AD-30 phono preamp, or the DAC-40 digital to analog converter.

BALANCED AAVA TYPE VOLUME CONTROL

AAVA performs volume adjustment by making use of a combination of 16 current signals with different magnitudes, thereby eliminating signal degradation and impedance fluctuations and maintaining a 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.

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).

POWER SUPPLY CIRCUITRY DESIGNED FOR OPTIMUM STABILITY

The strong power supply with a massive high-efficiency toroidal transformer and two large 60,000 μF filtering capacitors ensures a stable current supply at all times

THE HIGH DAMPING FACTOR BRINGS OUT THE FULL MUSICAL POTENTIAL OF LOUDSPEAKERS

Features such as Balanced Remote Sensing and MOSFET switches help to realize a damping factor of 1000. Superb motion control lets every loudspeaker perform at its very best.

BALANCED I/O

Integrated amplifier with fully balanced configuration extending from input to output.
