High-output integrated amplifier featuring Balanced AAVA

The E 5000 is the flagship high-power Class AB integrated amplifier developed to mark Accuphase’s 50-year anniversary. The pre amplifier 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 Accuphase E5000 integrated amplifier presents every piece of music in exquisite detail

Balanced AAVA volume control. Conventional pre amplifiers 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.

Quiet and smooth volume sensor design. The AAVA controls the volume levels by using its volume sensor to detect the position of the volume knob and then changing the combination of those signals. Accuphase developed the volume sensor in-house, using robust and heavy materials and crafting it using an aluminium block extrusion process to achieve smooth operations, a solid operation feel, and precise position detection when rotating the knob. It also suppresses operation sounds when using the Remote Commander to allow for quiet and pleasant volume adjustment.

Formidable power amplification stageThe 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 brings out the full potential of the loudspeakers. 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.
