Description

The Accuphase DP-570S SA-CD Player is a reference-grade digital source engineered for listeners who demand absolute precision and musical realism. Featuring a rigid, low-vibration SA-CD/CD transport and Accuphase’s advanced MDS+ D/A conversion with ANCC noise- and distortion-cancelling technology for exceptionally clean, natural sound. The DP-570S is designed to reveal the full depth and nuance of both SACD and CD recordings and offers balanced and single-ended analogue outputs alongside comprehensive digital connectivity, all housed in a beautifully finished chassis that reflects Accuphase’s renowned craftsmanship. The result is a refined, authoritative player that delivers effortless detail, tonal purity and long-term reliability at the heart of a truly high-end audio system.

Maximum stiffness – minimum vibration

The SA-CD/CD drive employs a high-stiffness construction that not only minimizes vibrations from internal rotation but also absorbs any external vibrations, whether large or small. The mechanical base is fully integrated with the massive and highly rigid chassis.

Floating type traverse mechanism.

Mechanical isolation between the traverse mechanism and the loading mechanism is provided by newly developed silicone type viscous dampers whose shape and material composition have been carefully optimized. Four of these are used to realise a floating design.

Dramatically enhanced quietness of operation.

Even though they may appear flat to the unaided eye, media discs often have slight eccentricities in dimensions and weight, as well as warping. When spinning at high speed, this leads to various types of vibrations and wind noise. Based on thorough research into these issues, the DP-570 features a strengthened rotation system and effective vibration frequency control, along with further improved vibration insulation. To combat wind noise, a larger bridge enabling air flow control is used, along with various other technology-based measures that result in a significant improvement in quietness. Disc rotation noise is reduced to about one third as compared to earlier designs.

Direct Balanced Filter configuration for analog filter.

The analog filter designed to remove so-called aliasing noise in the very high frequency range employs 5-pole Butterworth analog filters with extremely flat frequency response in the passband. In order to prevent unwanted interaction, completely separate low-pass filters are provided for the line and balanced signal paths.
