Description
Accuphase E-700
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.

■ Power amplification stage that achieves linear output
The power amplification stage on both the left and right sides features a large heat sink and employs four-fold parallel push-pull power transistors driven in Class A to provide linear power output of 35 watts into 8 ohms, 70 watts into 4 ohms, and 140 watts into 2 ohms.
■ Power supply circuitry delivers steady power
A strong power supply featuring a massive toroidal transformer and two high-voltage, large filtering capacitors (56,000 μF/50 V) offer a stable power supply at all times.
■ High damping factor brings out the full potential of speakers
The damping factor represents the amplifier’s ability to drive the speakers. A damping factor of 1,000 (guaranteed) extracts the maximum potential from the loudspeakers.
