The fifth generation MDS+ player and successor to the DP-570, the DP-570S advances Accuphase's disc player technology by applying \u003cstrong\u003eANCC (Accuphase Noise and Distortion Cancelling Circuit) to the MDS+ DAC for the first time\u003c\/strong\u003e, using four parallel ESS ES9028PRO DAC circuits with ANCC-equipped I-V conversion amplifiers for significantly lower distortion, improved linearity, and a quieter noise floor than the DP-570. A refined, more rigid custom SACD\/CD transport mounted on a multi-layer base plate for low center of gravity and maximum vibration control, programmable playlist functionality, a Direct Balanced Filter with completely separate line and balanced outputs, and comprehensive digital connectivity including USB Type-B, HS-LINK, coaxial, and optical inputs for DSD 22.5MHz and PCM 384kHz\/32-bit make the DP-570S both a reference disc player and a full-capability external DAC at Vinyl Sound Buffalo, NY USA. hi-fi+ reviewed the DP-570 and described the Accuphase sound as a very organic hint of subtle warmth, an underpinning sense of calm, an unforced and entirely natural-feeling level of detail, and an almost uncanny way with timing — qualities the DP-570S takes further through ANCC.\u003c\/p\u003e \n\n\u003ch2\u003eMDS+ with ANCC: Fifth Generation Parallel Delta-Sigma Conversion\u003c\/h2\u003e\n\u003cp\u003eThe DP-570S's defining advance over the DP-570 is the addition of ANCC (Accuphase Noise and Distortion Cancelling Circuit) to the MDS+ DAC's I-V conversion amplifier stage — the same technology introduced in the C-57 phono stage's MC head amplifier and applied throughout the C-3900S and E-800S. MDS+ (Multiple Delta-Sigma Plus) uses four parallel ESS ES9028PRO DAC circuits per channel, with each converter processing identical data simultaneously and the outputs combined to cancel uncorrelated conversion errors and thermal noise through statistical averaging. The four-parallel configuration uses four of the ES9028PRO's eight internal DAC channels per channel — equivalent to the approach used in the DP-570 — but the DP-570S adds ANCC at the critical I-V conversion stage between the DAC current output and the voltage output feeding the filter amplifier. ANCC detects residual noise and distortion components at the I-V converter input and injects a precisely calibrated inverted-polarity cancellation current, pushing the DP-570S's noise floor and distortion figures beyond what the MDS+ parallel architecture alone achieves. Vumetre, who heard the DP-570S at its debut, described it as far superior to the DP-570 in terms of noise reduction and fluidity.  The Direct Balanced Filter maintains completely separate circuitry for the balanced XLR and single-ended RCA outputs from the DAC through the output stage, preventing mutual interference between the two output paths for maximum performance on both.\u003c\/p\u003e\n\n\u003ch2\u003eRefined Transport, Digital Hub Capability, and System Integration\u003c\/h2\u003e\n\u003cp\u003eThe DP-570S uses a custom-developed SACD\/CD transport mechanism mounted on a multi-layer base plate with an exceptionally low center of gravity, reducing mechanical vibration at the drive before it can propagate into the electrical circuits and introduce noise or timing errors into the digital audio signal. The refined, more rigid transport mechanism compared to the DP-570 provides even quieter and more accurate disc reading across both the CD and SACD layers. Beyond disc playback, the DP-570S functions as a comprehensive external DAC with USB Type-B input for computer audio at PCM 384kHz\/32-bit and DSD 22.5MHz, HS-LINK for ultra-low-jitter integration with Accuphase digital components including the DG-78 voicing equalizer, and coaxial and optical S\/PDIF inputs for standard digital sources. Digital outputs allow the DP-570S to route its transport output to an external processor including the DG-78, enabling room correction to be applied in the digital domain before D\/A conversion. Programmable playlist functionality allows tracks to be arranged in a user-defined playback order, stored independently for multiple discs. The balanced output phase selector provides polarity inversion of the balanced XLR output independently of the single-ended output for system phase matching. For Accuphase systems in Buffalo, NY combining the DP-570S with the C-3900S preamplifier, DG-78 voicing equalizer, and A-48S or P-7500 power amplifiers, HS-LINK provides bit-perfect digital integration throughout the signal chain.\u003c\/p\u003e\n\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMDS+ DAC with ANCC (New for

is a high-end SACD\/CD player and external DAC from Accuphase of Japan, available at Vinyl Sound Buffalo. It is the fifth generation MDS+ player and successor to the DP-570, featuring four parallel ESS ES9028PRO DAC circuits with ANCC active noise cancellation at the I-V conversion stage — a first for this product line — a refined custom SACD\/CD transport, Direct Balanced Filter output, USB Type-B and HS-LINK digital inputs for PCM 384kHz\/32-bit and DSD 22.5MHz, digital transport outputs for external voicing equalizers, and programmable playlist functionality.\u003c\/p\u003e\n\n\u003ch3\u003eHow does the DP-570S differ from the DP-570?\u003c\/h3\u003e\n\u003cp\u003eThe Accuphase DP-570S advances over the DP-570 primarily through the addition of ANCC (Accuphase Noise and Distortion Cancelling Circuit) to the MDS+ DAC's I-V conversion amplifier stage, which was not present in the DP-570. ANCC detects and actively cancels residual noise and distortion components at the I-V converter, significantly reducing the DP-570S's noise floor and distortion figures below the DP-570's already low levels. The transport mechanism is also refined and more rigid for quieter and more accurate disc reading, and the digital conversion now supports DSD 22.5MHz via USB — higher than the DP-570's DSD maximum. MusicWorks UK described the DP-570S as improving upon the much-loved DP-570 with an upgraded digital board and revised MDSD conversion stage, extracting even more detail and refinement from discs.\u003c\/p\u003e \n\n\u003ch3\u003eCan the DP-570S be used as an external DAC with a streaming device?\u003c\/h3\u003e\n\u003cp\u003eYes, the Accuphase DP-570S functions as a full-capability external DAC for streaming devices, computers, and network players. Its USB Type-B input accepts PCM at up to 384kHz\/32-bit and DSD at up to 22.5MHz from any USB audio device. The HS-LINK input accepts digital audio from compatible Accuphase components at up to 384kHz\/32-bit PCM or DSD256. Coaxial and optical S\/PDIF inputs accept standard digital audio from streamers including Bluesound Node, Eversolo, and Technics. All digital inputs pass through the same MDS+ DAC with ANCC as disc playback, providing reference-level digital-to-analog conversion for streaming sources.\u003c\/p\u003e\n\n\u003ch3\u003eWhat is the HS-LINK digital connection and what does it enable?\u003c\/h3\u003e\n\u003cp\u003eHS-LINK is Accuphase's proprietary high-speed digital interface that provides bit-perfect digital audio transmission between compatible Accuphase components at up to 384kHz\/32-bit PCM or DSD256 without the jitter limitations of standard S\/PDIF coaxial or optical connections. In the DP-570S, HS-LINK is used both as an input from other Accuphase digital sources and as an output to connect the DP-570S's disc transport to the Accuphase DG-78 voicing equalizer for digital domain room correction processing before the signal is converted to analog. This digital processor loop, using the DP-570S's digital outputs and the DG-78's digital input and output, allows room acoustic correction to be applied to disc playback without any additional analog-to-digital conversion.\u003c\/p\u003e\n\n\u003ch3\u003eWhat SACD and CD formats does the DP-570S support?\u003c\/h3\u003e\n\u003cp\u003eThe Accuphase DP-570S supports standard SACD single-layer, SACD\/CD hybrid discs, standard CD, and data discs containing PCM or DSD audio files. For SACD playback, the player decodes the DSD signal from the disc and converts it through the MDS+ DAC with ANCC for analog output. For CD playback, the 16-bit\/44.1kHz PCM signal is processed through the four-parallel ES9028PRO MDS+ converter. Data disc playback supports high-resolution PCM and DSD file formats burned to standard optical disc media, extending the DP-570S's playback capability beyond the CD and SACD catalogue.\u003c\/p\u003e\n\n\u003ch3\u003eWhere can I buy the Accuphase DP-570S in Buffalo, NY?\u003c\/h3\u003e\n\u003cp\u003eThe Accuphase DP-570S SACD\/CD Player is available at Vinyl Sound USA Inc. in Buffalo, NY, your authorised Accuphase dealer serving Western New York and the United States.
