Description

Accuphase DP-570 MDS SACD Player

Equipped with quiet and smooth disc loading, the high rigidity and low centre of gravity of the SACD/CD drive vastly improves readability, while the MDS+ type D/A converter with four parallel circuits accurately reads disc information and converts analogue signals. It also supports a digital connection with a voicing equaliser and provides a programmable play list feature that lets you enjoy listening in the order you prefer. Enjoy listening to the Accuphase DP-570, the next step in the pursuit of the ideal disc playback experience.

Accurate Reading:- A high-rigidity SACD/CD drive mounted on a triple layer bottom plate with exceptional vibration reduction properties and all supported by high-carbon cast iron insulators. This configuration creates a strong integrated structure that suppresses the effect of external vibrations on the traverse mechanism. Four newly developed high-quality butyl “elastic dampers” connect the traverse and disc mechanisms, drastically reducing external vibrations from being transmitted to the traverse mechanism and protecting the lens actuator that reads discs. Music information is read accurately thanks to these vibration protection technologies and then sent to the digital processor.

Quiet Operation:- Vibrations from spinning discs are typically transmitted to the chassis, which then resonates and amplifies the operational sounds. The “elastic dampers” on the traverse mechanism greatly reduce chassis resonance. The five-layer large bridge cover surrounding the traverse mechanism also shields against air-vibration noise from high-speed rotation. This improvement allows the DP-570 to operate quietly without being affected by rotation.

Smooth loading:- Carved from an aluminium block and then finished by a hard anodised aluminium and satin treatment, the elegant and elaborate disc tray uses steel bearing shafts to open and close smoothly and quietly.

MDS+ type D/A converter with four parallel circuits:- The MDS+ (Multiple Delta Sigma+) conversion principle is a revolutionary D/A conversion routing that employs multiple delta-sigma type D/A converters connected in parallel for drastically improved performance. By driving four outputs from a high-performance ES9028PRO DAC chip (ESS Technologies) in parallel, the DP-570 almost doubles (=√4) overall performance for distortion, noise, linearity, and more. Because the improvements provided by the MDS principle are independent of signal frequency and level, output signal noise at very low levels is also minimised, a feat that conventional delta-sigma converters find extremely difficult to achieve.

Direct Balanced Filter circuit:- By making the line output circuits and balance output circuits independent of each other, the Direct Balanced Filter circuit does not affect the output signal even with two preamplifiers connected.

High-precision clock playback:– The high-performance (digital) audio interface chip AK4118A (Asahi Kasei Micro devices) drastically reduces jitter for high-precision clock playback.
