Accuphase E-5000 amplifier class A review

PRECISION INTEGRATED STEREO AMPLIFIERE E-5000

The E-5000 is the flagship high-power Class AB integrated amplifier developed to mark Accuphase’s 50-year
anniversary.
The preamplifier section features our superior Balanced AAVA volume control, while the power
amplifier section includes an instrumentation amp and power transistors in a five-fold push-pull arrangement driven in Class AB.
These circuits create a balanced circuit from input to output. With its precisely balanced circuits and solidly built output stage, the E-5000 integrated amplifier presents every piece of music in exquisite detail.

Balanced AAVA volume control Highly reliable logic-control signal switching relays
Ample input connectors (Five line level and two balanced)
Line level input and output connectors for a recorder.
Individual phase setting for each input
Stereo signal can be switched to monophonic operation
Left / right balance control through Balanced AAVA
Volume attenuator that can instantly reduce sound as low as –20 dB
Loudness compensator to adjust audible sonic balance.
Tone controls using summing active filters power amplification stage employs instrumentation amplifier principle
Current feedback amplification circuit topology assures excellent phase characteristics in high range
Speaker output protection circuit guards against short circuit
Protection circuitry using low impedance, highly reliable MOSFET transistors switches.
Two massive speaker connectors for output switching and simultaneous output
Line level and balanced outputs at the preamplifier section support bi-amping connection.
Line level and balanced inputs at the power amplifier section allow use as a power amplifier.
Dedicated, high-quality headphone amplifier constructed with discrete components
Two expansion slots for option boards.

The E-5000 has the highest output power in Accuphase integrated amps, the rated continuous average output is  240W/8Ω.
The E-5000 perfectly drives any loudspeakers even low-efficiency ones.

The E-5000 realizes -124dB（0.63μV） of equivalent
input noise equal to the flagship class-A integrated amp
E-800..

Remarks
*This product is available in versions for 120/220/230 V AC. Make sure that the Voltage shown on the rear panel matches the AC line voltage in your area.

*The 230 V version has an Eco Mode that switches power off after 120 minutes of inactivity.

*The shape of the plug of the supplied AC power cord depends on the voltage rating and destination country.
