PD-501HR

Enjoy high-resolution audio without the need for a PC connection. CD Player with 5.6MHz DSD Disc Native Playback

Introduction

The PD-501HR is a high-quality disc player with 5.6MHz DSD file native playback and up to 24bit/192kHz PCM on recordable DVD discs. Featuring unique VACS (Vibration Acoustic Control Structure) to control vibrations, separate power supplies for analog and digital sections, the PD-501HR really is an uncontested disc player.

Specification

Unique Vibration Control Mechanism "VACS" Vibration Acoustic Control Structure
While reading signals from a rating disc, vibrations may cause a read error and negatively affect the sound quality by missing some of the original data on the disc. To eliminate vibrations and reach perfect data reading, the PD-501HR employs a unique vibration control mechanism, VACS, for a smooth rotation. After dozens of evalution tests the VACS instrument was chosen and fixed to the drive of the unit in order to achieve the best possible performance.

Cirrus Logic's Flagship DSD-Supported DAC CS4398
A celebrated CS4398 by Cirrus Logic is utilized to achieve 120dB of dynamic range. The CS4398 also employs un-damped volume control and a Mismatch Shaping Technology to eliminate distortion caused by capacitor mismatching.

JRC NJM5532 for Operational Amplifier on Analog Section
The field-proven and well-reputed JRC's NJM5532 operational amplifier has been applied to the analog circuits.

6-layer Circuit Boards to Simplify Signal Paths
In order to reduce the signal paths throughout the circuits, each part has been carefully laid out on 6-layer glass-epoxy motherboards. This design reduces and simplifies the signal paths and helps improve the sound quality.
Separated Power Supply Units for Digital and Analog Sections. Cleaner Power Supply by Schottky Barrier Diodes
Separate power supply units for the digital and analog sections help prevent digital noise that can leak across the sections over the current. Schottky Barrier Diodes are also employed on the rectifier circuit to supply cleaner current by eliminating rectification noise.

Excellent Audio Performance
By engaging various technologies and know-hows learned over decades the PD-501HR is one of the highest performing CD players with 20-80kHz of frequency response, 116dB of S/N ratio, 118dB dynamic range, and 0.004% of THD on PCM playback
