Accuphase DC-1000 Precision MDSD Digital Processor

Product Description

The Accuphase DC-1000 MDSD Digital Processor, launched to celebrate Accuphase’s 50th anniversary, is a reference-grade digital-to-analog converter (DAC) designed for audiophiles seeking the pinnacle of digital audio performance. Featuring an 8MDSD/8MDS++ D/A converter with eight parallel ESS ES9038PRO channels, a fully balanced signal path, and Accuphase’s ANCC low-noise technology, the DC-1000 delivers a pristine, vibrant soundstage with exceptional dynamics and transparency. Its champagne gold panel, persimmon wood side panels, backlit display, and meticulous Japanese craftsmanship make it a luxurious centerpiece for high-end hi-fi systems. Supporting high-resolution digital inputs up to 32-bit/384kHz PCM and DSD256, it pairs perfectly with transports like the DP-1000 for unparalleled digital playback.  

Key Features  

• 8MDSD/8MDS++ D/A Converter: Eight parallel ESS ES9038PRO DAC circuits per channel achieve 2.8x performance improvement in distortion, noise, and linearity, with MDSD filtering for DSD signals to eliminate high-frequency noise.  
  
• Fully Balanced Signal Path: Dual Direct Balanced Filter with four low-noise monolithic ICs per channel ensures pristine audio with minimal interference and excellent phase accuracy.  
  
• Versatile Connectivity: Includes HS-Link (up to 32-bit/384kHz PCM, DSD256), coaxial (32 kHz–192 kHz/24-bit PCM), optical (32 kHz–96 kHz/24-bit PCM), and USB (up to 11.2896 MHz DSD, 32-bit/384kHz PCM) digital inputs; coaxial, optical, and HS-Link digital outputs; and balanced XLR and unbalanced RCA analog outputs.  
  
• Low Noise Design: Achieves a signal-to-noise ratio of 120 dB and total harmonic distortion of 0.0005%, delivering noise-free, high-fidelity audio.  
  
• ANCC Technology: Advanced Noise and Distortion Cancelling Circuit, derived from Accuphase amplifiers, enhances signal purity for transparent playback.  
  
• Robust Power Supply: Two toroidal transformers (one for analog, one for digital) with 80,000μF filtering capacitors ensure stable, clean power with complete circuit separation.  
  
• Digital Level Control: Adjustable output level (0 to -40 dB) for precise integration with preamplifiers like the Accuphase C-3900 or C-2900.  
  
• Intuitive Controls: Front-panel controls and RC-250 remote offer easy operation, with real-time display of input signal bitrate and DSD frequency (MHz).  
  
• Elegant Design: Champagne gold panel, persimmon wood side panels, and backlit display reflect Accuphase’s premium craftsmanship.  
  
• Handcrafted in Japan: Meticulous construction with premium components ensures reliability and sonic excellence.
