Accuphase DC-1000

Accuphase celebrates 50 years of manufacturing with the DC-1000, a digital processor developed to deliver the ultimate in performance and sound quality. It is equipped with the ES9038 PRO (ESS Technologies) processor: an 8MDSD (DSD signal) / 8MDS++ (PCM signal) type D/A converter that drives 8 channels in parallel to deliver almost 3 times more performance than single channel converters. Low-noise technologies refined during development of the amplifiers, like amplification of ANCC and internal signals and parallel arrangement of power circuits, allow the DC-1000 to deliver unprecedented levels of emotion.

• MDSD / MDS++ D/A converter driving 8 parallel channels using ANCC

• Dual Direct Balanced Filter with completely separate line and balanced signals

• Separate toroidal transformers for analog and digital circuits

• Separate low noise power supply circuits for analog and digital circuits

• Display with sampling frequency and number of quantization bits

• Output level adjustments that can control different outputs from other players

• Digital interface for Accuphase Voicing Equalizer

• Abundant digital inputs like USBs, etc. to connect with computers (HS-LINK, USB, OPTICAL × 2, COAXIAL × 3, BALANCED)

• Digital outputs that can be used in digital recording (OPTICAL, COAXIAL)

• 2 (BALANCED, LINE) analog outputs

• Phase selector that can invert the balanced output

• Active filter amplifiers use glass cloth fluorocarbon resin substrate with low dielectric constant and minimum loss

• Natural grain wood case with a mirror finish crafted by artisans using carefully selected virgin wood

• 8 mm thick machined aluminum bottom plate

• Advanced high-carbon cast iron insulators

• High quality audio cable ASL-10B
