Integrated Stereo Amplifier

Since the E-303 launching in 1978, the high-power integrated amp is at the core of Accuphase product lineup. The E-480 is a succession model of E-470, it is the 11th generation of “Accuphase Core Product”.The E-480 Preamplifier section features the further evolved AAVA that enables an accurate volume control. The power amplifier section, a damping factor is further enhanced with precise and dynamic speaker driving ability. The preamplifier and power amplifier sections are kept entirely separate, users are able to combine E-480 with other separate systems.

Option Boards

A range of sophisticated option boards opens up even more possibilities. The newly developed Digital Input Board DAC-40 features a USB port and support for high-bit, high-sampling frequency signals up to 192 kHz/24 bits. The newly developed Analog Disc Input Board AD-30 is also available, ideal for high-grade reproduction of analog records using either MC or MM phono cartridges.
