The Accuphase E-5000 is the flagship high-power Class AB integrated amplifier developed to mark Accuphase’s 50-year anniversary. The E-5000 is known for its exceptional sound, advanced features, and outstanding build quality. Being a fully balanced design provides a high signal-to-noise ratio, low distortion and wide dynamic range. It also has a large power supply and a very high-quality power amplifier section. The E-5000 is designed for use with high-impedance loads, and it is capable of delivering high power output levels with minimal distortion.
It has a built-in preamplifier, which allows users to adjust the volume and tone of the audio signals before they are sent to the power amplifier. It also includes a range of digital inputs and digital audio processing capabilities, including a high-quality digital-to-analog converter, which allows users to play high-resolution digital audio sources.
The Accuphase E-5000 is highly respected and sought-after piece of audio equipment among audiophiles and music enthusiasts, and is considered one of the best integrated amplifiers in the market.
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.
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
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.
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.
