Overview
The Accuphase E-700 is a pure Class A integrated amplifier that sits near the top of Accuphase's celebrated integrated range. It delivers the warmth, low level resolution, and effortless midrange that Class A operation is famous for, paired with the engineering rigor and long term reliability that define the Accuphase house sound. This is a component built for listeners who prize tonal purity and refined dynamics over raw wattage on paper.
At its heart is Accuphase's AAVA volume control, which manages level in the current domain rather than with a conventional resistive potentiometer. This approach keeps signal to noise performance and channel balance consistent at every listening level, so the amplifier sounds equally composed at low volume and at concert levels. Instrumentation feedback circuitry and a robust power supply with a large toroidal transformer support that clean, stable presentation into demanding loads.
The E-700 is ideal for the enthusiast building a reference two channel system who wants one refined box to do the work of a separate preamplifier and power amplifier. Its expansion slots accept optional analog and digital input boards, letting you tailor it to phono and streaming or DAC duties as your system evolves. It rewards resolving, well built loudspeakers and thoughtful source components with a sound that is detailed yet never fatiguing.

How the E-700 Compares
Accuphase E-700 vs Accuphase E-800S
The E-800S sits above the E-700 in the Accuphase range and offers more of everything the E-700 does well, with greater Class A output, an even larger power supply, and headroom for the most demanding loudspeakers. If your room is large or your speakers are especially power hungry, the E-800S gives extra reserve and grip. The E-700 remains the more compact and approachable choice for most rooms while sharing the same core Class A character. See the Accuphase E-800S.
Accuphase E-700 vs Accuphase E-4000
The E-4000 is an AB class integrated that trades some of the E-700's Class A midrange bloom for higher rated wattage and a lively, high current presentation. It is an excellent match for listeners who want maximum drive and dynamic slam from a single box. The E-700 leans toward tonal refinement and low level detail, making it the choice for those who prioritize purity over peak power figures. See the Accuphase E-4000.
Accuphase E-700 vs Luxman L-509Z
The Luxman L-509Z is a high power integrated with Luxman's ODNF feedback and LECUA volume control, offering a slightly warmer, fuller bodied balance and abundant drive. The Accuphase E-700 emphasizes the clarity and delicacy of pure Class A with its AAVA volume system. Both are reference level designs, so the choice comes down to which tonal character and control philosophy suits your ears and system. See the Luxman L-509Z.
Recommended Speakers
