The Accuphase E-4000 Integrated Amplifier is a high-end audio component that delivers 180 watts per channel into 8 ohms and 260 watts per channel into 4 ohms. It features six unbalanced (RCA) and three balanced (XLR) inputs, offering versatility in connectivity. The amplifier's design includes Accuphase's proprietary AAVA (Accuphase Analog Vari-gain Amplifier) volume control and ANCC (Accuphase Noise and distortion Cancelling Circuit) technology, which together ensure low noise and distortion levels across all listening volumes. The E-4000's sound signature is described as highly refined and musical, with a deep, controlled bass, detailed midrange, and smooth, extended highs, making it well-suited for both critical listening and immersive musical experiences. Its impressive damping factor of 800 contributes to its ability to drive a wide range of loudspeakers with authority and precision.
