At the pinnacle of Class-A amplification, the Accuphase E-800S redefines integrated amplifiers with its perfect blend of performance, reliability, and craftsmanship. Every detail has been carefully engineered, making this amplifier not just a piece of audio equipment but a long-term investment for discerning audiophiles. Built to last decades, the E-800S is designed to deliver uncompromised sound quality, standing tall against more complex pre-power combinations—at a fraction of the cost.
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.
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 massive high-efficiency toroidal transformer and two large 60,000 μF filtering capacitors ensures a stable current supply at all times
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.
