Ooberpad announces the availability of the power-packed Accuphase E-800 Class-A Precision Integrated Stereo Amplifier. The E-800 is positioned above the E-650 as the new flagship model in the integrated amplifier lineup of Accuphase. The preamplifier section is feature-packed with the flawless Balanced AAVA type volume control, while the power amplifier section is configured as an instrumentation amplifier leveraging a six-fold parallel push-pull configuration of power MOS-FETs driven in pure Class A. The final 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 core of the music.

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.

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