Who is this for?

The Accuphase E-800S is designed for listeners seeking true high-end performance without the complexity of separate components. It’s ideal for experienced HiFi enthusiasts who value musicality, refinement, and long-term build quality as much as power and detail.

Its pure Class-A design particularly suits those who enjoy a natural, effortless presentation with rich tonal depth and exceptional realism. The E-800S pairs beautifully with premium loudspeakers in medium to large listening rooms, delivering the kind of smooth authority and control normally associated with far more complex systems.

For customers upgrading from premium integrated amplifiers or simplifying an existing separates setup, the E-800S offers a genuine reference-level solution built for years of listening enjoyment.

What makes the Accuphase E-800S different from other integrated amplifiers?
The E-800S combines Accuphase's flagship integrated amplifier engineering with a pure Class-A power amplifier stage, fully balanced circuitry and its sophisticated Balanced AAVA volume control. The result is a high-end amplifier designed to deliver exceptional refinement, precise control and natural musical expression without requiring separate preamplifier and power amplifier components.

How much power does the Accuphase E-800S deliver?
The E-800S delivers 50 watts per channel into 8 ohms, 100 watts into 4 ohms and 200 watts into 2 ohms. It can also deliver up to 300 watts into a 1-ohm load with music signals. This impressive power delivery across different impedances allows the amplifier to work confidently with a wide range of compatible loudspeakers.

What are the benefits of Class-A amplification?
Class-A amplification keeps the output devices conducting throughout the audio waveform, avoiding crossover distortion associated with switching between output devices. This design is valued for its smooth, refined presentation, low distortion and ability to reproduce subtle musical details with natural tonal richness.

What is Balanced AAVA volume control?
Balanced AAVA is Accuphase's proprietary volume-control technology. Rather than relying on a conventional resistive volume control, it adjusts the audio signal through a sophisticated current-based circuit. This helps maintain a high signal-to-noise ratio and low distortion across the volume range, preserving fine musical detail at different listening levels.

Can the Accuphase E-800S drive demanding speakers?
Yes. Its substantial power supply, high current capability and damping factor of 1,000 provide excellent control over loudspeaker drivers. Its power increases as speaker impedance decreases, making it a strong candidate for a variety of high-performance speakers. Speaker sensitivity, impedance characteristics and room size should still be considered when choosing a suitable match.

What inputs does the Accuphase E-800S have?
The E-800S offers balanced XLR inputs and unbalanced line-level inputs for connecting compatible sources such as CD players, DACs and music streamers. It also includes two expansion slots for optional boards, allowing you to add digital or analogue phono connectivity.

Can I connect a turntable directly to the Accuphase E-800S?
Yes, provided you install the optional AD-60 phono input board. This allows you to connect a compatible turntable and enjoy vinyl playback without needing a separate external phono preamplifier. Cartridge compatibility should be checked before choosing the appropriate phono configuration.

Can I connect a digital music streamer to the E-800S?
Absolutely. You can connect a streamer or external DAC through the amplifier's analogue inputs. Alternatively, the optional DAC-60 board adds digital inputs for compatible digital sources, providing additional system flexibility.

Can the E-800S be used with a separate power amplifier?
Yes. Its preamplifier and power amplifier sections can be separated, allowing the E-800S to serve as a dedicated preamplifier when paired with a suitable external power amplifier. This flexibility provides an upgrade path for listeners who want to explore separate components in the future.

Does the Accuphase E-800S have a headphone output?
Yes. It features a dedicated headphone amplifier circuit designed to deliver high-quality personal listening. It supports headphones with an impedance of 8 ohms or higher.

Is the Accuphase E-800S suitable for a high-end two-channel hi-fi system?
Very much so. The E-800S is designed for discerning music lovers who want outstanding stereo performance, refined Class-A amplification and premium build quality in one integrated component. It is an excellent centrepiece for a reference-level system built around quality loudspeakers and high-performance digital or analogue sources.

How much space does the Accuphase E-800S require?
The amplifier measures 465 mm wide, 239 mm high and 502 mm deep, with a net weight of 35.7 kg. Its substantial construction means you should allow sufficient shelf space, ventilation and a suitably strong equipment rack. As a Class-A amplifier, it also produces considerable heat during operation, so adequate ventilation is important.
