Accuphase E-4000. An Integrated 180W/channel possibly the Finest in a Solid State Stereo Amp. Period.
Now at True Audiophile
The E-4000 replaces the beloved and vaulted 480. When we say, "period" we don't kid. Accuphase has a low product due to their legendary build quality and sound.
Since the E-303 launching in 1978, the high-power integrated amp is at the core of Accuphase product lineup.
E-4000 is a succession model of E-480, it is the 12th generation of “Accuphase Core Product”.
The E-4000 integrated amplifier has emerged from separate amplifier technologies.
The preamplifier section features AAVA using ANCC to allow for volume adjustments that maintain high levels of vibrancy. The power amp section employs balanced transmission utilizing the instrumentation amplifier principle to drive noise suppression to its limit.
The E-4000 is equipped with a four-fold parallel push-pull configuration of power transistors driven in Class AB in the output stage to extract every last ounce of potential from the speakers and create soundscapes filled with subtlety.
- Revolutionary AAVA volume control
- Four-fold parallel push-pull configuration of power transistors driven in Class AB
- High power output of 180 watts into 8 ohms / 260 watts into 4 ohms
- Power amplification stage configured as instrumentation amplifier
- High damping factor of 800
- Strong power supply with massive high-efficiency toroidal transformer
- High-voltage, large filtering capacitors
- Protection circuitry using MOS-FET switches
