Accuphase DP-570S MDS SA-CD Player

Accuphase DP-570S Super Audio CD and CD Player with MDS+ DAC and External Digital Inputs

The finest single-box disc player Accuphase has built at this price tier, now with ANCC noise canceling at its analog core and a transport mechanism that rivals far more expensive machines.

A Generational Step Forward From the DP-570

Accuphase does not issue revised models lightly. When the Yokohama-based manufacturer adds the letter S to an existing product name, as it has done with the E-800S, A-48S, C-3900S, and now the DP-570S, it signals a specific class of engineering improvement rather than a cosmetic refresh. In the case of the DP-570S, the defining addition is ANCC: Accuphase Noise and Distortion Canceling Circuit. This technology, which was not present in the DP-570, applies a secondary sub-amplifier in the current-to-voltage conversion stage of the DAC section. The sub-amplifier monitors the main amplifier's output for residual noise and distortion components and actively subtracts them from the signal. The result is not a marginal tweak. Across all listening levels, but particularly at the quiet, low-signal passages where digital artifacts most readily surface, the DP-570S retrieves a quality of inner detail and spatial information that the DP-570, for all its considerable merits, could not consistently deliver.

The MDS+ Architecture: Four DACs Operated as One

The digital-to-analog conversion engine at the heart of the DP-570S is Accuphase's MDS+ system, an acronym that stands for Multiple Delta Sigma Plus. At its core sits the ESS ES9028PRO chip, a high-specification converter manufactured by ESS Technologies. Rather than operating a single chip in conventional fashion, Accuphase drives all four available outputs from the ES9028PRO in parallel per channel, yielding a total of four parallel DAC circuits across the stereo signal path. Running multiple delta-sigma converters in parallel is not simply an additive exercise. Because each converter's noise and distortion errors are statistically independent, combining their outputs causes the errors to partially cancel one another while the signal reinforces. The mathematical improvement in noise floor, linearity, and distortion approaches the square root of the number of parallel circuits, which in the case of four circuits means performance that approaches twice the level achievable from a single converter. The ANCC stage then takes this already refined output and applies active cancellation of the residual noise that even the parallel MDS+ topology cannot fully eliminate, pushing the DP-570S's signal-to-noise ratio to 121 dB and total harmonic distortion plus noise to a measured 0.0006 percent.

Mechanical Engineering as Acoustic Engineering

Accuphase has long maintained that the mechanical behavior of an SA-CD and CD transport is inseparable from its sonic performance. The argument is not abstract: a laser pickup reading a spinning disc at high speed is subjected to continuous vibration from the disc rotation itself, from the motor driving the disc, and from the chassis resonances that propagate through the player's structure. Any instability that reaches the optical pickup introduces timing errors in the data stream, and those timing errors degrade the accuracy of the downstream conversion regardless of how refined the DAC may be. The DP-570S addresses this problem at every level. The SA-CD and CD drive assembly is mounted on a three-layer base plate recessed into the bottom of the chassis, creating a low center of gravity that reduces the lever-arm effect of chassis vibration on the mechanism. High-carbon cast iron insulators beneath the chassis provide a combination of mass and internal damping that absorbs and dissipates energy rather than reflecting it back into the structure. The disc loading mechanism uses elastic dampers developed through Accuphase's own materials research to isolate the objective lens and actuator from resonances generated during loading and playback. A five-layer bridge cover, spanning the entire traverse mechanism, shields the transport from both acoustic and mechanical interference from outside the player. The disc motor itself is an outer rotor brushless DC design, chosen specifically because it generates less mechanical vibration and operating noise than conventional motor designs. The disc tray, machined from a solid aluminum block and finished with hard-anodized satin treatment, operates on high-quality steel bearing shafts that allow it to open and close with a degree of quietness and precision that immediately communicates the quality of the machine beneath.

The Direct Balanced Filter: Separate Signal Paths From DAC to Output

The DP-570S provides both balanced XLR and single-ended RCA outputs, and the design philosophy governing these outputs is worth understanding before you configure your system. Many players share a common analog signal path after the DAC stage and then passively convert or split to provide both output types. The Accuphase approach is fundamentally different. The Direct Balanced Filter circuit maintains completely separate signal paths for the balanced and line outputs from the moment the signal leaves the current-to-voltage conversion stage. Each output type has its own dedicated filter amplifier assembly, optimized specifically for its operating conditions. The balanced output uses a true differential topology with separate normal-phase and reverse-phase amplification, while the line output runs an independent single-ended circuit. This means that connecting to either output does not compromise the integrity of the other, and that the balanced output is a genuine differential signal rather than a pseudo-balanced conversion of a single-ended stage. Both outputs deliver 2.5 volts at 50 ohms, a level carefully chosen to interface cleanly with the input sensitivity of most high-end preamplifiers. A rear-panel phase selector switch allows the balanced output polarity to be inverted without rewiring, an important practical feature in systems where absolute phase consistency across sources matters.

A Complete External DAC and Digital Hub

The DP-570S is not a disc player that happens to have a USB input. It is a genuine digital hub designed to serve as the primary source component in a reference-caliber system regardless of whether you are spinning physical media or processing high-resolution files from a computer. The digital input suite includes Accuphase's proprietary HS-LINK connection, a USB Type-B port, coaxial S/PDIF, and optical S/PDIF. Via USB and HS-LINK, the player accepts PCM signals at resolutions up to 384 kHz and 32 bits and DSD signals up to 22.5 MHz one-bit natively, with DoP support up to 11.2 MHz. The coaxial input handles PCM up to 192 kHz at 24 bits, and the optical input accepts PCM up to 96 kHz at 24 bits. For users who own compatible Accuphase components such as a voicing equalizer, the HS-LINK digital outputs and transport outputs allow the digital signal from the DP-570S to be routed through external processing and returned before the final conversion stage, enabling room-correction and acoustic correction to be applied in the digital domain without introducing an additional analog conversion step. The player's display shows the current sampling frequency and quantization bit depth for any input, giving you immediate confirmation of the resolution of whatever source is playing.

How the DP-570S Compares to the DP-770

The natural question for a buyer considering the DP-570S is how it relates to the DP-770, which sits above it in Accuphase's current disc player lineup and carries a US list price of $26,575. The DP-770 introduces the MDSD architecture, a further evolution of the parallel delta-sigma principle that increases the number of parallel DAC circuits and applies more aggressive noise shaping. The DP-770 also uses a more elaborate chassis construction with additional vibration isolation layers and a heavier overall mass of 22 kilograms compared to the DP-570S's 18.4 kilograms. The gap between these two machines is real and audible under serious listening conditions, and the DP-770 represents a meaningful step upward in measured and perceived performance. That said, the DP-570S with ANCC closes that gap substantially compared to the original DP-570 without ANCC. For a buyer whose system is built around an Accuphase or other high-quality preamplifier in the $10,000 to $20,000 range, the DP-570S will reveal everything that preamplifier and the downstream amplification are capable of communicating. The DP-770 becomes the logical next step only when the rest of the system has been optimized to a level where the DP-570S becomes the limiting factor, which is a genuinely high bar to reach.

Frequently Asked Questions

Does the Accuphase DP-570S include a built-in phono preamplifier?

No, the DP-570S does not include a phono preamplifier of any kind and is not designed for direct connection to a turntable. It is a disc playback and digital conversion component. If you are building a system that includes both vinyl and disc playback, you will need a separate phono stage, either as a standalone unit, as a module installed in a compatible Accuphase integrated amplifier, or as a feature of a preamplifier such as the Accuphase C-47 or the optional AD-2900 module for the C-2900. We are happy to discuss phono stage options that complement the DP-570S at any price point.

Does the DP-570S come with a cartridge?

The DP-570S has nothing to do with cartridges and does not ship with one. It is a Super Audio CD and CD player, not a turntable. The included accessories are a remote commander (RC-150), an AL-10 RCA audio cable, a two-meter AC power cord, and a USB driver disc with setup guide for customers who intend to use the USB input for computer audio. There is no cartridge, stylus, or tonearm of any kind.

What is ANCC and why does it matter?

ANCC stands for Accuphase Noise and Distortion Canceling Circuit. It is a proprietary Accuphase technology that places a secondary sub-amplifier alongside the main amplifier in the current-to-voltage conversion stage that follows the DAC output. The sub-amplifier monitors the main amplifier's output, identifies the noise and distortion components that have been added by the main amplifier's own circuit behavior, and feeds those components back in inverted form so they cancel out before reaching the output. The practical benefit is measurable and audible: the DP-570S achieves a signal-to-noise ratio of 121 dB and total harmonic distortion plus noise of 0.0006 percent, and low-level musical information such as decays, reverb tails, and fine spatial cues comes through with a clarity that requires careful listening to fully appreciate. ANCC was not present in the original DP-570, making it the most significant sonic advancement in the S upgrade.

How does the DP-570S compare to the Accuphase DP-770?

The DP-770 is the next model up in Accuphase's current disc player range and carries a US list price of $26,575. It uses the MDSD converter architecture, a more advanced implementation of the parallel delta-sigma principle than the MDS+ system in the DP-570S, combined with additional vibration isolation engineering and a heavier, more heavily braced chassis at 22 kilograms versus the DP-570S's 18.4 kilograms. In a well-configured reference system, these differences are audible: the DP-770 offers a somewhat lower noise floor and finer low-level resolution under direct comparison. However, the DP-570S with ANCC has substantially narrowed the performance gap that existed between the original DP-570 and the DP-770. For most high-performance systems in the mid-to-upper tier of the market, the DP-570S will not be the limiting factor in what the system can communicate. The DP-770 becomes the more compelling choice when the rest of the chain, including preamplifier, power amplifier, and loudspeakers, has been optimized to a level where the DP-570S itself begins to impose a ceiling.

Does the DP-570S play SACDs?

Yes. Super Audio CD playback is a primary function of the DP-570S. The player uses a dedicated optical pickup with a 655 nm laser wavelength for SA-CD reading, separate from the 790 nm laser used for standard CD reading. It supports two-channel SA-CD in full native DSD resolution. It does not support multi-channel SA-CD, which is consistent with the design of virtually all current high-end SA-CD players that prioritize two-channel performance over multi-channel capability. It also plays standard Red Book CDs, CD-R and CD-RW discs, and data discs in DVD-R and DVD-RW formats containing WAV, FLAC, DSF, and DSDIFF audio files.

Can I use the DP-570S as a standalone DAC without playing discs?

Yes, and this is one of the most compelling aspects of the DP-570S as a long-term investment. The player accepts external digital signals through four input types: HS-LINK (Accuphase proprietary), USB Type-B, coaxial S/PDIF, and optical S/PDIF. Via the USB input, it accepts PCM at up to 384 kHz and 32 bits and DSD at up to 22.5 MHz one-bit natively. This means a computer, a network streamer with a USB or S/PDIF output, or any other digital source can route audio through the DP-570S's MDS+ and ANCC conversion stage and benefit from the same precision that governs disc playback. The front panel display confirms the input sampling frequency and bit depth in real time. You can use the DP-570S purely as a DAC for years after your disc collection is fully catalogued and ripped, and the machine will continue to perform at exactly the same level.

What cables and connections do I need to get started?

The DP-570S ships with Accuphase's own AL-10 audio cable, a one-meter RCA interconnect that connects the player's LINE output to a preamplifier or integrated amplifier. For most buyers, this cable is sufficient to begin listening immediately. If you prefer to use the balanced XLR output, you will need a compatible XLR interconnect such as the Accuphase ALC-10B or a third-party equivalent. If you intend to use the USB input for computer playback, a USB 2.0 cable with a Type-B connector at the player end is required, and the included driver disc should be installed on Windows computers before connecting. Mac users typically do not require a separate driver. If you plan to connect the DP-570S to an Accuphase voicing equalizer or another HS-LINK compatible component, the proprietary AHDL HS-Link cables are required and are available separately. We are glad to help you select exactly the cables you need for your specific configuration.

What is the output level control and when would I use it?

The DP-570S includes a digital output level control that adjusts the player's analog output from 0 dB down to minus 20 dB in one-decibel increments. This is not a substitute for a preamplifier and should not be used as a primary volume control for day-to-day listening. Its intended purpose is system matching: if you are replacing a source component that operated at a different output level, or if your preamplifier's gain structure places the volume control in an awkward range when connected to a full-level 2.5-volt source, the output level control allows you to trim the DP-570S's output to achieve a more comfortable operating range. It is also useful if you are comparing the DP-570S directly to another source in your system and want to level-match the comparison accurately.

What does the programmable playlist feature do?

The DP-570S allows you to program a custom playback sequence for the tracks on a CD or data disc. Rather than playing tracks in the order they appear on the disc, you can specify the track number and order you want before playback begins. This is particularly useful for listeners who curate their own listening experience from discs with mixed content, or for those who prefer to hear a set of tracks in a specific sequence that differs from the original program order. The feature is operated via the remote commander and the front panel display, which shows the total track count and playback program in real time. It is a practical convenience that reflects Accuphase's attention to the full listening experience rather than just the playback chain.

Does the DP-570S require any warm-up time before serious listening?

Like all high-quality analog circuit components, the output stages and filter amplifiers in the DP-570S perform at their best after the circuits have reached thermal equilibrium. Accuphase designs its products for long-term, continuous-use operation, and many owners leave the unit powered on at all times. The 18-watt power consumption makes this practical and economical. If the unit has been powered off for an extended period, an hour of warm-up at operating temperature is a reasonable expectation before the sound settles fully. The 230-volt version of the DP-570S includes an Eco Mode that powers the unit down after 120 minutes of inactivity; the 120-volt US version sold by All Elite Audio does not include this feature, leaving the idle-on decision entirely to the owner.

Where can I buy the Accuphase DP-570S, and why should I buy from All Elite Audio?

The Accuphase DP-570S is available exclusively through the brand's authorized dealer network in the United States. All Elite Audio is an authorized Accuphase dealer, which means every unit we sell is a genuine US-specification 120-volt model carrying the full manufacturer warranty and full eligibility for factory service. Purchasing through an unauthorized channel, including international sellers, eBay listings of foreign-specification units, and grey-market importers, voids the manufacturer warranty and may result in a unit wired for 220 or 230 volts. At All Elite Audio, you are buying the right product for your market, from a dealer who has made it our business to understand the Accuphase line in depth. We invite you to visit our showroom, hear the DP-570S in a properly configured system, and speak with our staff about how it fits into your specific equipment goals.
