Accuphase DP-470 CD Player

Accuphase DP-470 CD Player

The newly announced DP-470 is the successor to the DP-450, which was released in 2021. It has evolved to meet the needs of today’s digital audio environment, not only by delivering higher-quality CD playback but also through enhanced USB DAC functionality and a revised circuit design.

The DP-470 is a next-generation CD player that brings out the full appeal of CDs while allowing users to enjoy a wide variety of digital audio sources with high sound quality.

Improved DAC Performance With Greater Detail

The DAC performance has been significantly improved through the use of ESS’s ES9026PRO DAC device, combined with Accuphase’s MDS+ system, which uses four circuits driven in parallel for greater precision and lower distortion. When paired with Accuphase’s proprietary ANCC technology, this design delivers performance that rivals higher-end models. Further improvements to D/A conversion accuracy have been achieved through optimised component placement and reduced power supply noise, resulting in an improved signal-to-noise ratio of 120dB, dynamic range of 117dB and channel separation of 114dB.

Accurate Reading

Vibration countermeasures in CD players that read audio data from rotating discs greatly impact the sound quality. By placing the high-rigidity drive mechanism as close to the base as possible, the DP-470 significantly reduces external vibrations from being transmitted to the traverse mechanism and protects the lens actuator that reads the discs. The high-quality elastic dampers that connect the traverse and disc loading mechanisms reduce the magnification of natural resonances in the lens actuator, improving reading precision.

Additionally, the chucking magnet is an 8-pole neodymium bonded magnet for high magnetic flux density and dimensional accuracy. This chucking magnet secures the turntable and disc evenly and firmly to enable uniform disc rotation without wobbling.

Quiet Operation

Creating a quiet listening environment is a vital component in enjoying music. Vibrations from spinning discs that are transmitted to the chassis resonate and amplify operational sounds. The elastic dampers that support the traverse mechanism inhibit vibrations from discs and greatly reduce chassis resonance. The three-layer large bridge surrounding the traverse mechanism also shields against vibrational noise from high-speed rotation. This technological development allows the DP-470 to operate quietly without being affected by disc rotation.

MDS+ (Multiple Delta Sigma) Type D/A Converter with Four Parallel Circuits

The MDS+ conversion principle is a revolutionary D/A conversion routing method that employs multiple delta-sigma type D/A converters connected in parallel for drastically improved performance. By passing output from the high-performance ES9026PRO DAC chip (ESS Technologies) through 4 parallel converter circuits, the DP-470 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 can also be minimized, a feat that conventional delta-sigma converters find extremely difficult to achieve.
