In an era where streaming dominates headlines and convenience often trumps craftsmanship, Accuphase quietly reminds us of something important: great disc playback is far from obsolete. With the DP-570S, the Japanese high-end specialist delivers a SACD/CD player that doesn’t cling to the past—but instead refines it, integrates it, and elevates it to modern reference level.
This is not just a disc spinner. The DP-570S is designed as a serious digital hub, equally at home playing SACDs as it is serving as a high-performance DAC for external digital sources. For listeners with carefully curated disc libraries who also want seamless integration with modern digital systems, the DP-570S hits a rare sweet spot.
Accuphase has always treated mechanical engineering as an essential part of sound quality, and the DP-570S is a textbook example. The custom SACD/CD drive is mounted on a multi-layer base with an exceptionally low center of gravity, reducing vibration at the source before it ever reaches the signal path. Add the high-carbon cast metal isolating feet and a carefully damped disc-loading mechanism, and you get a transport that feels calm, controlled, and utterly unflustered in operation.
In real listening terms, this obsessive mechanical stability translates into effortless playback—free from the subtle timing errors and micro-instabilities that can blur musical detail.
MDS+ DAC with ANCC
At the heart of the DP-570S sits Accuphase’s latest MDS+ (Multiple Delta Sigma) D/A converter architecture. Four delta-sigma converter circuits operate in parallel, averaging out errors and lowering noise, distortion, and non-linearity. It’s a classic Accuphase solution: not chasing exotic chips, but refining topology and execution.
This is further enhanced by ANCC (Accuphase Noise and Distortion Cancelling Circuit), which uses an additional sub-amplifier to actively suppress unwanted noise components. The payoff is most obvious in quiet passages—where low-level detail, decay, and spatial cues remain intact instead of dissolving into digital haze.
Fully balanced analog stages
On the analog side, Accuphase employs its Direct Balanced Filter design, with completely separate signal paths for balanced and unbalanced outputs. Each output has its own dedicated amplifier stage, minimizing crosstalk and preserving signal purity regardless of which connection you use.
A phase selector for the balanced outputs adds welcome flexibility, making system matching easier in complex high-end setups. It’s a small detail, but exactly the kind of thoughtful engineering Accuphase users expect.
While disc playback is clearly the soul of the DP-570S, its versatility is what makes it truly modern. In addition to SACD and CD, it can play data discs containing PCM and DSD files—and it also functions as a full-fledged external DAC.
Connectivity is comprehensive: USB Type-B for computer audio, HS-LINK for ultra-low-jitter integration with compatible Accuphase components, plus coaxial and optical S/PDIF. PCM signals are supported up to 32-bit/384 kHz via USB and HS-LINK, while DSD playback reaches up to DSD256. This makes the DP-570S just as relevant in a contemporary digital system as it is in a traditional disc-based one.
There are even digital outputs for those who want to insert external processors—such as voicing equalizers—into the signal chain.
Everyday usability
Despite its serious engineering, the DP-570S is refreshingly easy to live with. The clear front-panel display shows not only track and time information, but also sampling rate and bit depth—useful feedback for those who like to know exactly what’s playing. Programmable playlists allow custom track sequences, a feature that becomes invaluable with large disc collections.
Operation is smooth and intuitive, whether from the front panel or the supplied remote.
The Accuphase DP-570S is a statement—not loud, but deeply confident. It treats disc playback not as a nostalgic indulgence, but as a legitimate, modern source worthy of the same attention as high-resolution streaming. By combining a meticulously engineered transport, a reference-grade MDS+ DAC, and extensive digital connectivity, Accuphase has created a player that feels timeless rather than dated.
For listeners who still treasure their SACD and CD collections—and want them to coexist seamlessly with modern digital sources—the DP-570S is exactly the kind of component that makes long-term sense.
