The DCD-2500NE is also endowed with custom parts, such as high-sound-quality electrolytic capacitors and polyphenylene sulfide capacitors, which have been co-developed with parts manufacturers through an extensive regimen of repeated listening te.
An aluminum plate has also been combined to the underside of the steel transformer base to strengthen rigidity.
Dedicated power unit for analogue audio circuitryA newly developed original Denon large-capacity (3300 F) block capacitor is used for the power unit of the analog audio circuitry after the D/A converter.
By carefully restoring data that was lost during digital recording, the resulting playback sound is highly detailed, free of interference, accurately localized, richly expressive in the lower range, and beautifully faithful to the original sound.
Independent digital and analog power transformersThe power units for the digital and analog circuits, whose signals have different characteristics, have separate transformers to eliminate mutual interference and noise.
These algorithms interpolate points that should exist before and after the points in large quantities of data to achieve a smooth waveform that is close to that of the original signal.
The DCD-2500NE is equipped with two clock oscillators, one for each sampling frequency (44.1 kHz and 48 kHz), that can be switched between the frequencies to thoroughly suppress jitter.
Advanced AL32 Processing PlusThe DCD-2500NE is equipped with Advanced AL32 Processing Plus, the latest version of Denons analogue waveform reproduction technology which utilizes unique data interpolation algorithms and also supports high-resolution sound sources.
A conductive polymer capacitor with particularly outstanding high-frequency impedance characteristics for Denons renowned sound quality has been placed at the base of the clocks power source, and an ultra-compact film capacitor that is different from layered ceramic capacitors has been placed close to the clock, to achieve an improved S/N ratio and a transparent sound with superior spatial expression.
The clock power circuit has also been vastly improved to bring out the full potential of the high-quality clocks performance.
The DCD-2500NE thus employs a clock oscillator to dramatically reduce phase noise that is the displacement of frequencies.
In addition, the quality of the clock, which becomes the reference for semiconductor operation, is extremely important for ensuring that the digital audio circuitry performs at its maximum potential.
Positioning the master clock immediately adjacent to the D/A converter (DAC) suppresses jitter and ensures optimum precision in D/A conversion.
By eliminating unwanted vibration, servo-related operations are minimized, and by also minimizing unnecessary controls and current consumption, digital signals can be read from the disc with optimum accuracy under stable conditions.
DAC Master Clock DesignTo accurately synchronize digital circuits, the DCD-2500NEs DAC Master Clock Design treats the DAC as the master when clock signals are supplied.
In addition, the mechanisms low center of gravity suppresses any vibration occurring inside the mechanism due to disc rotation, and the mechanism structure also effectively suppresses external vibration.
Improvements in high-mass, vibration-resistant properties and the dispersal of resonation points contribute to a high level of vibration resistance.
The various parts of the mechanism have been made with different materials such as a combination of stainless and copper plating for the top panel to strengthen rigidity, diecast aluminum for the disc tray, and 2mm thick steel for the mechanism brackets.
Signal paths have been shortened to an absolute minimum and circuits have been miniaturized to ensure that excess current or noise will not occur.
The circuitry that controls the pickup and decodes the signals read from the disc has been newly developed. (Suppress Vibration Hybrid) Mechanism.
