Accuphase DC-1000 Digital Audio Processor

PRECISION MDSD DIGITAL PROCESSOR

Accuphase make some of the finest audio equipment in the world and we can't recommend them highly enough. All of their components will deliver a marked improvement to any system and are a fantastic base to a new build or an unparalleled upgrade to an existing one.

The Accuphase DC-1000 Digital to Analogue converter breaths life into the CD and SA-CD format. Paired with the DP-1000 SACD transport the performance rivals that of high end turntables.

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

The DC-1000 brings an 11% improvement in noise levels over the DP-950 at just 123dB.

Features

MDS++ type D/A Converter with 8 Parallel circuits and support for 384 kHz (32 bit 2 Channel PCM) The Parallel implementation which is incredibly difficult to achieve compared to a single converter circuit improves overall performance by a factor of three.
