The DAC-60 is a digital input board that can input digital signals directly into amplifier units when installed in Accuphase preamplifiers and integrated amplifiers (listed below). Three input types are provided (USB, OPTICAL, COAXIAL) for connection to a broad range of digital devices. The D/A converter adopts the “2MDS+ (Multiple Delta Sigma) converter principle” with ES9016K2M (ESS Technologies) mounted in parallel to convert analog signals that remain extremely true to the original source sound. Born from cutting-edge audio technologies, the DAC-60 is an option board that provides truly high-quality and fully expressive performances.
