Accuphase DC-1000

Celebrating 50 years of manufacturing with the Accuphase 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.

DSD signals contain a large amount of quantisation noise  at frequencies higher than the range of human hearing, so digital filters have to be used to remove high frequency noise. Typically, DSD signals are converted into PCM signals before being input into the digital filter. The MDSD principle employed in the DC-1000, however, generates 8 phase shifted DSD signals and then inputs them to the 8 channels in the MDS++ type D/A converter. The entire circuit then operates as a moving average filter with completely linear phase characteristics to eliminate high frequency noise. MDSD represents a ground-breaking playback method that does not convert DSD signals into  PCM signals, but instead operates as a filter that eliminates high frequency noise.

The MDS++ conversion principle is a revolutionary D/A conversion method that employs multiple delta-sigma type D/A converters connected in parallel for drastically improved performance. By passing output from the high performance ES9038PRO (ESS Technologies)  through 8 parallel converter channels, the DP-1000 provides a theoretical 2.8 (=√8) increase in overall performance for distortion, noise, linearity, and more. Because the improvements provided by the MDS++ principle are independent of signal frequency and level, output signal noise at very low levels can also be minimised, a feat that conventional delta sigma converters find extremely difficult to achieve

Accuphase DP-1000

The DP-1000 is the culmination of Accuphase’s 50-year pursuit of creating the ideal compact disk transport. This high rigidity, high precision drive is equipped with a silent and elegant disc loading mechanism. The outer rotor brushless DC motor smoothly rotates the disc, while the newly developed dampers protect the pickup from vibrations. Incorporating a number of technological improvements like a low center of gravity and fortified frame alongside features like programmable playlists, the DP-1000 is the ideal transport to quietly and accurately read data.

• High-rigidity, high-precision aluminium machined SA-CD/CD drive
• Low-noise power supply circuits and separate toroidal transformers for mechanical system and signal processing
• Programmable playlists so that you can enjoy your music in the order you want
• Accuphase voicing equaliser and digital connections
• Digital outputs (HS-LINK / COAXIAL)
• Low placement of the SA-CD/CD player for a low centre of gravity
• “Power-on play” that automatically starts playback with a timer (sold separately)
• HS-LINK Ver. 1 / Ver. 2 switching
• Data disc playback including DSD discs
• Natural grain wood case with a mirror finish crafted by artisans using carefully selected virgin wood
• 12 mm thick machined aluminium bottom plate
• Advanced high carbon cast iron insulators
• Supplied with HS-LINK cable AHDL-15

The Accuphase DC-1000 and DP-1000 together form a stunning optical disk play back system. Each unit however can be purchased separately to complement or enhance an existing transport or processor.
