Accuphase E-4000
Beschrijving / Description
The E-4000 integrated amplifier is a succession model of E-480, the 12th generation Accuphase Class-AB high-power integrated stereo amplifier. The Preamplifier section provides a low-noise AAVA volume control with a fully refined circuit configuration and layout. The Power amplifier section adopted the bipolar transistors in a four-fold parallel push-pull arrangement and made a significant achievement for the driving ability of loudspeakers. The E-4000 extracts the full potential of any loudspeaker to reproduce sound overflowing with energy and vividness.
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.
A strong power supply featuring a massive toroidal transformer and two high-voltage, large filtering capacitors (40,000 uF/80 V) offers a stable power supply at all times.
