Introduction

As Accuphase’s flagship integrated amplifier, the E-800 merges preamplifier finesse and power-amp muscle into a single, elegant chassis. It delivers the musical insight of a separate-component system with the simplicity and synergy of a unified design—bringing you closer to the heart of the music.

Design

• Fully Balanced Signal Path: From every input through to the outputs, no single-ended stages compromise channel separation or noise performance.
• Balanced AAVA™ Volume Control: Accuphase’s signature Analog Vari-gain Amplifier varies gain, not attenuation, preserving signal integrity and channel matching at all levels.
• Instrumentation-Amplifier Power Stage: A pure Class-A, six-fold parallel push-pull MOS-FET array drives speakers with effortless authority and zero sonic coloration.

Application

Use the E-800 as the centerpiece of your two-channel system: connect digital sources, phono stages, tuners or streaming modules, then feed speakers or an external power amp. In variable-output mode it can even drive headphones directly, making it an all-in-one solution for serious listening.

Technology Overview

• Six-Fold Parallel Push-Pull MOS-FETs: Operated in pure Class-A, this configuration yields the dynamic slam of a power amp twice its size—yet with the purity and refinement of the finest tube amps.
• Massive Toroidal Transformer & Filtering: A high-efficiency toroid and large-value capacitors provide rock-steady current delivery, even during the most demanding musical climaxes.
• MOS-FET Protection Switching: Fast-acting, silent protection circuits guard against overloads and speaker faults without compromising sound quality.
