Precision Engineering for CD Playback

At the heart of the DP-470 is a precision CD drive mechanism engineered for exceptionally stable and quiet operation. A large three-layer bridge provides excellent vibration isolation, while an elastic damper protects the optical pickup from resonance. A powerful magnetic chucking system and smooth-loading disc mechanism further contribute to accurate, reliable playback.

Digital-to-analogue conversion is handled by the ESS ES9026PRO DAC combined with Accuphase’s MDS+ architecture, using four parallel conversion circuits to improve performance and reduce noise. Together with Accuphase’s proprietary ANCC technology, optimised component placement and improvements to the power supply, the DP-470 achieves a signal-to-noise ratio of 120 dB, dynamic range of 117 dB and channel separation of 114 dB.

Advanced DAC Performance

The DP-470 is also a highly capable standalone DAC. Its upgraded USB input supports DSD up to 11.2 MHz using DoP and native DSD up to 22.5 MHz via ASIO, allowing high-resolution digital sources to benefit from the same sophisticated conversion circuitry used for CD playback.

Styling has also been refined with design cues taken from Accuphase’s flagship players, including an intricately finished gold-anodised disc tray and revised front-panel controls. The new RC-150 remote control completes a player designed to combine traditional CD enjoyment with the flexibility demanded by contemporary digital audio systems.

Who is this for?

The Accuphase DP-470 is ideal for music lovers with a serious CD collection who want to hear those discs at their best, while still having the flexibility to use modern digital sources. Its high-quality transport, 4MDS+ DAC architecture and low-noise circuitry make it a strong choice for listeners who value refinement, detail and long-term build quality.
It also suits anyone looking for a premium digital hub rather than just a CD player. With USB, optical and coaxial digital inputs, the DP-470 can be used as a high-performance DAC for a computer, network player, TV or other digital source, making it well suited to a high-end two-channel system that combines physical media with contemporary digital playback.

What is the Accuphase DP-470?
The DP-470 is a high-performance CD player and digital-to-analogue converter. It combines a precision CD transport with Accuphase’s 4MDS+ D/A conversion system, while also allowing external digital sources to use its internal DAC.

What DAC does the DP-470 use?
The DP-470 uses four ESS ES9026PRO DAC circuits operating in parallel as part of Accuphase’s 4MDS+ conversion system. This is combined with Accuphase’s ANCC technology to reduce noise and distortion.

Can the DP-470 be used as a standalone DAC?
Yes. The DP-470 has USB, optical and coaxial digital inputs, allowing devices such as computers, network players and televisions to take advantage of its internal D/A converter.

Does the DP-470 support high-resolution audio over USB?
Yes. USB PCM playback is supported up to 384 kHz/32-bit. DSD playback is supported at 2.8, 5.6, 11.2 and 22.5 MHz, with DoP supported up to 11.2 MHz.

What digital inputs does the DP-470 have?
The DP-470 includes USB Type B, coaxial and optical digital inputs. It also provides coaxial and optical transport outputs for connection to external digital equipment.

What analogue outputs are provided?
The DP-470 offers both balanced XLR and RCA line outputs. Both provide a rated output of 2.5 V with an output impedance of 50 ohms. A phase selector is also provided for the balanced output.

What is the advantage of the DP-470's CD drive mechanism?
The transport has been engineered to minimise vibration and mechanical noise. It uses elastic dampers, a large three-layer bridge and an 8-pole neodymium chucking magnet to help maintain stable, accurate disc rotation and reading.

Can I connect the DP-470 to a television?
Yes. A television can be connected to the DP-470's optical digital input, allowing the player's internal DAC to convert the TV's digital audio signal for playback through a stereo system. The TV's digital output needs to be set to PCM.

Can the DP-470 be connected to an Accuphase voicing equalizer?
Yes. The coaxial or optical transport outputs and digital inputs can be used to connect a compatible voicing equalizer, allowing CD playback to be processed in the digital domain.

Does the DP-470 have adjustable output level?
Yes. The digital output-level control can be adjusted from 0 dB to -60 dB in 1 dB increments, making it easier to match its playback level with other source components.

Does the DP-470 include a remote control?
Yes. The DP-470 is supplied with the Accuphase RC-150 Remote Commander.
