High output integrated amplifier

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.

Features

Balanced AAVA Volume Control

Conventional preamplifiers use variable resistors to adjust volume, which causes contacts to deteriorate and create grit as well as increase noise at normal volume levels. AAVA, however, produces multiple, widely varying signals from the input signal and controls volume by changing the combination of those signals. This achieves minimum noise at all volume levels without any grit. The E-5000 with its balanced AAVA circuits delivers exceptional noise suppression performance.

Formidable Power Amplification Stage

The power amplification stage on both the left and right sides is equipped with a large heat sink and employs five-fold parallel push-pull power transistors driven in Class AB to provide rated, high-power output of 240 watts into 8 ohms and 320 watts into 4 ohms

High damping factor

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.


Power supply circuitry designed for optimum stability

A strong power supply featuring a massive toroidal transformer and two high-voltage, large filtering capacitors (40,000 μF/100 V) offers a stable power supply at all times.
