Features

The E-700 has a Pure Class A operation (35 watts into 8 ohms). Guaranteed linear power: 120 watts into 2 ohms, 60 watts into 4 ohms, 30 watts into 8 ohms; and the preamplifier and power amplifier sections can be used separately.

Balanced AAVA volume control

One of the key features of the E700 is its Dual Balanced AAVA volume control system. AAVA stands for "Accuphase Analog Vari-gain Amplifier," which is a proprietary technology that provides precise and accurate volume control with minimal noise and distortion. The Dual Balanced AAVA system uses two separate AAVA circuits for left and right channels, which helps to maintain perfect channel balance and stereo imaging.

Output stage with power MOS-FETs in triple parallel push-pull configuration

Triple parallel push-pull output stage with power MOS-FETs and power amplifier stage mounted on a large heat sink. Two identical units are arranged on the left and right sides of the chassis.

Balanced I/O

Instrumentation amplifier principle in power amplifier for fully balanced signal transmission, complemented by MCS+ topology and current feedback amplification circuitry.

Strong power supply with massive high-efficiency toroidal transformer and large filtering capacitors.

The E-700 uses a massive power transformer with high output capability. Highly effective filtering is realized with two custom-made aluminum electrolytic capacitors, each with a large 56,000 μF rating.

HiFi+

The Accuphase E-700 is an exceptional performer. It has authority, power, dynamics, rhythmic energy, and grip while offering subtlety and inner detail where it is needed. When someone really hits a tom or snare, the E-700 conveys its impact and delights the listener with subtle insights into a delicate cymbal line or the technique and style of a skilled guitarist or sax player.

Who is this for?

The Accuphase E-700 is perfect for listeners drawn to the purity and intimacy of Class-A amplification. It suits music lovers who prioritise tonal richness, soundstage depth, and long listening sessions free from fatigue.

Its beautifully smooth and organic presentation pairs exceptionally well with high-resolution speakers in small to medium-sized listening rooms. The E-700 excels with vocals, jazz, acoustic music, and classical recordings where texture and realism are especially important.

For customers seeking a refined, emotionally engaging listening experience with the unmistakable character of pure Class-A sound, the E-700 is a deeply rewarding amplifier.
