The E-4000 integrated amplifier is the successor to Accuphase's highly regarded E-480. Noise levels are significantly lower, with the E-4000 being around 20% less than its predecessor, thanks to a revised AAVA volume control system and ANCC circuit.
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 180 watts into 8 ohms and 260 watts into 4 ohms.
High damping factor
The damping factor represents the amplifier’s ability to drive the speakers. A damping factor of 800 (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.
Investing in the Accuphase E-4000 is more than just purchasing a piece of equipment; it's an investment in a reference-grade audio experience. This amplifier is designed to satisfy the most discerning audiophiles, offering a level of performance that is truly exceptional.
