High-output integrated amplifier featuring Balanced AAVAThe 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.

Innovation – The leading edge of technology■ Balanced AAVA volume control
Conventional preamplifiers use variable resistors to adjust volume, whichcauses 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 ofthose signals. This achieves minimum noise at all volume levels without anygrit. 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 theposition of the volume knob and then changing the combination of those signals.
Accuphase developed the volume sensor in-house, using robust and heavymaterials and crafting it using an aluminum block extrusion process to achievesmooth operations, a solid operation feel, and precise position detection whenrotating the knob. It also suppresses operation sounds when using the RemoteCommander to allow for quiet and pleasant volume adjustment.

Sound quality – Simply aiming for the best
■ Formidable power amplification stage
The power amplification stage on both the left and right sides is equipped with a large heatsink 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.

Toroidal transformer■ 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.
