Accuphase DP-570S SACD/CD Player

Accuphase DP-570S SACD/CD Player with DSD & PCM Playback

With a sophisticated design surrounding graceful disc loading, a solid disc drive, and a D/A converter employing unique low-noise, low-distortion ANCC technology, many years of accumulated expertise have created a highly evolved SACD/CD player. Ample input and output terminals, programmable playlists that allow you to enjoy music in your preferred order, and digital connections to a voicing equalizer add additional appeal. You will undeniably relish how the DP-570S recreates all your favourite songs.

Accurate Reading

Vibration countermeasures in SACD/CD players that read audio data from rapidly rotating discs greatly impact sound quality. The DP-570S uses a highly rigid SACD/CD drive mounted on a three-ply bottom plate with exceptional vibration dampening capabilities to create a low centre of gravity. Additionally, high-carbon cast iron insulators support the structure, preventing the housing from wobbling and significantly reducing external vibrations from reaching the traverse mechanism. The disc loading mechanism supports the traverse mechanism using elastic dampers born from research into shapes and materials. This reduces resonance in the objective lens and actuator that read the discs, thus improving reading precision. Music data is read accurately thanks to these vibration protection technologies and then sent to the digital processor.

Comfortable Listening Environment

Creating a quiet listening environment is a critical detail for any SACD/CD player. The motor that rotates the discs employs an outer rotor brushless DC motor to minimize vibrations and operating noise. The five-layer large bridge cover surrounding the traverse mechanism also shields against vibrational noise from high-speed disc rotation.

Smooth Disc Loading

Carved from an aluminium block and then finished with a hard anodized aluminium and satin treatment, the elegant and elaborate disc tray uses high-quality steel bearing shafts to open and close smoothly and quietly.

MDS+ D/A Converter with Four Parallel Circuits using ANCC

MDS+ drives multiple delta-sigma type D/A converters connected in parallel to provide drastically improved performance. By driving four outputs from a high-performance ES9028PRO DAC chip (ESS Technologies) in parallel, the DP-570S almost doubles (=√4) overall performance for distortion, noise suppression, linearity, etc. 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 minimized, a feat that conventional delta-sigma converters have extreme difficulty achieving.

The I-V conversion amplifier uses the low-noise, low-distortion ANCC (Accuphase Noise and distortion Cancelling Circuit) principle, further enhancing the effect provided by MDS+. ANCC is a technology that improves performance by using a sub-amplifier to cancel noise and distortion in the main amplifier.

Direct Balanced Filter Circuit

To output an ideal signal, the DP-570S uses a Direct Balanced Filter circuit with independent line and balanced output circuits.

Our Review

The Accuphase DP-570S is one of those players that feels luxurious before you’ve even hit play, with its silky, sculpted disc tray and beautifully damped, whisper-quiet loading setting the tone for a thoroughly refined listening experience. Under the hood, Accuphase’s serious engineering chops shine through: the highly rigid, low-centre-of-gravity drive, clever vibration control, and outer-rotor brushless motor all work together to keep the music data pristine before it even reaches the digital stage. And when it does, the MDS+ D/A converter - with four parallel ES9028PRO circuits and that clever ANCC noise-cancelling magic - serves up a sound that’s clean, natural, and effortlessly detailed at any volume. Add in generous connectivity, thoughtful touches like programmable playlists, and the unmistakable sense that every mechanical movement has been obsessively perfected, and the DP-570S becomes more than a disc player - it’s a wonderfully polished way to rediscover your favourite albums.
