MDSD Digital Processor Accuphase DC-950

Full Description

Overview

A digital processor that redefines the state of the art — Digital signal processing is implemented

through an ultra-high-speed FPGA in conjunction with innovative MDSD reproduction

technology, forming a double-speed high-precision moving-average filter circuit for straight D/A

conversion of the DSD signal. Eight digital inputs including USB with support for 11.2896 MHz

(1-bit 2-channel DSD) and 384 kHz (32-bit 2-channel PCM), as well as an HS-LINK connector

(Version 1 and 2) provide enhanced versatility for the ultimate in performance and sonic purity.
