Denon DCD-2500NE Silver Super Audio CD Player

Denon is one of the few brands that continues to improve its Hi-Fi components and accumulates, updates and implements its Hi-Fi audio technologies. The 2500 NE series is designed to meet today's audio listening requirements, with the involvement of both distinguished veterans and young talented engineers who have followed Denon's achievements and the experience that has been accumulated over many years and decades of the company. The main objective of the DCD-2500 NE is to provide the main functions of a CD player: ultra-high-precision reading of files and transmission of high-resolution audio to the amplifier. To achieve this goal, the signal paths were made minimally short and entire circuits were reduced. The developers also upgraded the suspension mechanism and chassis of the Drive to eliminate vibration – an avid enemy of CD players, and achieve the most vibration-resistant playback. Information on the disk is now read with perfect accuracy and purity, and a high-level signal is transmitted to the electronic circuit of the Advanced AL 32 processor. In addition to reading CDs and Super Audio CDs, the DCD-2500 NE It can also play high-resolution audio recordings up to PCM 192/24 or DSD 5.6 recorded on DVD R/RW.
he design of the DCD-2500 NE disc Drive includes an improved S. V. H. (Suppress Vibration Hybrid) mechanism, also used in Hi-end players. The circuit that controls the readout and converts the signals read from the disk has been improved. Signal paths have been shortened to an absolute minimum, and electrical boards have been designed to prevent excessive current or noise. Various parts of the mechanism are made of durable materials, such as stainless steel with a copper coating used in the body of the mechanism to increase strength, cast aluminum - for the disk Drive, steel with a thickness of 2 mm - for the suspension of the loading mechanism. Improving the properties in general, suppressing unwanted vibrations and scattering resonant points allows you to achieve high vibration stability. In addition, the low center of gravity of the mechanism suppresses any vibrations that occur inside the mechanism when the disk rotates. Thanks to the elimination of unwanted vibrations, the number of remote-controlled operations is also reduced, in addition, by minimizing unnecessary controls and energy consumption, digital signals can be read from the disk with optimal accuracy under stable conditions.

The DCD-2500 NE uses a DAC Master Clock Design clock generator to accurately synchronize digital circuits. As a master clock device directly adjacent to the digital-to-analog converter (DAC), it suppresses jitter and provides optimal D/A conversion accuracy. In addition, the quality of the synchronization device that connects solid-state operations is extremely important to ensure the maximum potential of the digital audio circuit. Thus, the DCD-2500NE player uses a clock generator to significantly reduce phase noise, which is a frequency offset. The power supply network of the synchronization device has also been significantly improved to ensure high-quality operation potential of such a device. To get the sound quality that you are famous forDenon, a conductive polymer capacitor with stunning high-frequency impedance characteristics is placed at the base of the sync device's power supply, and an ultra-compact film capacitor, different from multilayer ceramic capacitors, is placed next to the sync device to achieve improved signal-to-noise ratio and crisp sound with excellent spatial expression. The DCD-2500NE features two syncing oscillators, one for each sample rate (44.1 kHz and 48 kHz), which can switch between frequencies to completely eliminate jitter.
The DCD-2500NE also has custom parts, such as electrolytic capacitors and high-quality polyphenylene sulfide capacitors, which were jointly developed with part manufacturers through repeated listening tests. All these elements are responsible for the stability and reliability of the power supply, resulting in a delightfully balanced sound.

The "simple and direct" design philosophy was best implemented in all DCD-2500 NE circuits. The circuitry was designed from scratch to make the signal paths as short as possible and to ensure that the original sound is accurately reproduced over the sound range. As a result, interference between the circuits, between the left and right channels, as well as side effects on audio signals are minimized, so that a clear, transparent sound is reproduced.
