Please Call For Price.
Accuphase E-4000 – We only stock brands that we love at HFL so it was a pleasant surprise when I had an opportunity to listen to the Accuphase E-650 and instantly I was smitten, I have to say I was almost won over by the looks before it had even created a singe note, the presentation sounds just right though, honest but with a tad of warmth giving a very natural sound so if you are looking for a new amp, pre or source feel free to get in touch to arrange a demo of Accuphase.
The E-4000 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 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.
