ACCUPHASE DP-570S

The Accuphase DP-570S is not merely a SACD/CD player, but a true manifesto of Japanese audio engineering, capable of transforming digital playback into a fully immersive sensory experience. The solid aluminum tray moves with millimeter-precise fluidity, and the disc, cradled in its precision mount, begins to spin smoothly, delivering each note with a dimensionality and naturalness that only reference Japanese players can offer. It is the ideal device for those seeking the quintessence of analog sound within the digital domain.

Accuphase’s proprietary transport mechanism is the result of decades of research into optical playback. The three-layer base plate, equipped with high-carbon cast-iron dampers, lowers the center of gravity and fully isolates the optical assembly from external vibrations. The DC brushless motor with external rotors eliminates any mechanical interference, while the solid aluminum disc tray with high-quality steel axles ensures flawlessly smooth loading and unloading. The five-layer bridge cover encases the mechanism like an acoustic shield, isolating it from noise generated by high-speed rotation.

At the heart of the DP-570S lies its digital-to-analog conversion section, where proprietary 4MDS+ (4 Multiple Delta-Sigma+) technology deploys four DAC circuits per channel in a parallel configuration, utilizing a pair of 32-bit ESS Sabre ES9028PRO converters for a total of 64 operational DACs. Supported by the ANCC circuit (Accuphase Noise and distortion Cancelling Circuit), the player achieves extraordinary performance: THD+N of just 0.0006%, signal-to-noise ratio of 121 dB, dynamic range of 118 dB, and channel separation of 117 dB. These figures allow every SACD, CD, or DSD file to be reproduced with surgical precision, delivering an incredibly defined and three-dimensional soundstage.

The listening experience offered by the DP-570S is remarkable. Every detail emerges clearly, from the fastest transients to the decay of a crash cymbal, from the breath of a cello to the resonance of a soundboard, with a naturalness and depth that make listening engaging even at low volumes. The Dual Direct Balanced Filter transmits balanced signals on separate paths, eliminating mutual interference and preserving timbral purity even in the most complex orchestral passages. Native support for DSD up to 22.5 MHz and PCM up to 32-bit/384 kHz allows playback of high-resolution master recordings without any degradation, including DSF, DSDIFF, WAV, and FLAC files burned on DVD-R, with the same fidelity as commercial SACDs. The HS-Link Ver. 2 interface separates RAW data from the clock, eliminating jitter and ensuring a fully synchronous audio chain.

The player features audiophile-grade XLR and RCA outputs, and digital inputs including USB Type-B, S/PDIF coaxial, optical Toslink, and HS-Link, making it versatile as a DAC for external sources such as streamers, music servers, and computers. The digitally adjustable level control down to -80 dB allows direct connection to power amplifiers, removing the need for preamplifiers, while the phase inversion function optimizes coherence in complex chains.

Weighing 19 kg and with a carefully designed internal layout, separating analog, digital, power, and logic control sections, the Accuphase DP-570S requires a stable, well-ventilated rack. The power supply, featuring an oversized toroidal transformer and custom 15,000 µF Nippon Chemi-con capacitors, provides a constant energy reserve even during the most demanding musical passages.

The DP-570S embodies half a century of Accuphase know-how: since 1972, every component has been designed, tested, and hand-assembled in Yokohama laboratories, following strict quality principles that ensure reliability and longevity. Owning a DP-570S means possessing a piece of audio history, capable of maintaining its sonic and emotional quality for decades.

Compared to other reference SACD players such as the Esoteric K-05XD or Marantz SA-10, the DP-570S stands out for its proprietary transport and 4MDS+ architecture with 64 operational DACs, ensuring superior linearity and microdynamics. Unlike solutions like the dCS Bartók, which combines DAC and streamer, the Accuphase prioritizes the purity of the physical SACD/CD source while integrating advanced digital features without compromise.
