Accuphase E-700 Class-A Precision Integrated Stereo Amplifier

Description 

The E-700 is an evolutionary integrated amplifier that incorporates numerous technologies from our 50th anniversary flagship model, the E-800. The preamplifier section uses a Balanced AAVA type volume control with ANCC to create a balanced configuration from input to output and achieve driving perfection. The power amp stage that drives the speakers has been fortified from three elements to four, further increasing reliability. Experience the full breadth of emotion in live performances with the E-700’s superior expression.

Features

The Accuphase E-700 is an integrated amplifier with a fully balanced configuration from input to output, featuring a Balanced AAVA volume control and a high-accuracy, high-rigidity volume sensor construction. Its power amplification stage is configured as an instrumentation amplifier and uses a four-fold parallel push-pull configuration of power MOS-FETs driven in Class A.

The E-700 delivers a linear power output of 35 watts into 8 ohms, 70 watts into 4 ohms, and 140 watts into 2 ohms, with 160 watts into a 1-ohm load for music signals. A high damping factor of 1,000 provides strong loudspeaker control. The amplifier also features a strong power supply equipped with a high-efficiency toroidal transformer and large filtering capacitors, while MOS-FET switch-based protection circuitry provides reliable protection during operation.
