Introduction

Marking Accuphase’s 50th anniversary of innovation, the DC-1000 is a flagship digital processor engineered to set new standards in sonic purity and emotional impact. At its heart lies the ES9038PRO ESS-based MDSD/MDS++ converter, driving eight channels in parallel to deliver nearly three times the performance of conventional single-channel DACs.

Design

Housed in a handcrafted cabinet with natural wood side panels and a milled-aluminum base plate, the DC-1000 combines luxurious aesthetics with exceptional vibration control. High-carbon cast-iron insulators further isolate the chassis, while premium ASL-10B internal cabling and glass-cloth fluorocarbon PCB substrates ensure the lowest possible dielectric losses throughout the signal path.

Application

As the centerpiece of a high-end digital front end, the DC-1000 accepts signals from a wide array of sources—computers, streamers, transports—and provides pristine data to downstream DACs or digital recorders. Programmable display of sampling frequency and bit depth keeps you informed of incoming formats, while output-level adjustment and phase inversion let you tailor its behavior to any system.

Technology Overview

• Precision MDSD/MDS++ Conversion
  Eight parallel delta-sigma modulators combine DSD-rate signals into a linear-phase moving-average filter, removing ultrasonic noise without PCM conversion.
• Dual Direct Balanced Filter
  Completely separate line-level and balanced digital paths maintain isolation and prevent crosstalk.
• Low-Noise Power Architecture
  Independent toroidal transformers and dedicated regulator circuits for analog and digital sections eliminate mutual interference.
• Galvanic Isolation & Reclocker
  Deep-buffered reclocking and isolated I/O prevent ground-loop and jitter artifacts.
