Focused on High-End Music Playback: Denon DCD-1700NE SACD/CD Player Features Advanced AL32 Processing Plus and DAC Master Clock Design

If you want bells and whistles on your SACD/CD player, look elsewhere. The Denon's DCD-1700NE focuses on the essential components, engineering, and build necessary to achieve remarkable high-end sound. DCD-1700NE specializes in ultra-high-precision disc reading, maintaining signal purity via minimized paths, vibration-defeating mechanisms, and optimal conversion via its DAC Master Clock Design. The latter treats the 32-bit TI 1795PCM DAC as the master when clock signals are supplied: suppressing jitter, reducing phase noise, and enhancing accuracy.

Contributing to the player's excellent measurement specifications, the internal circuitry features separate power transformers for the digital and analog sections, resulting in clean, transparent sound free of interference. Denon also created an original drive complete with a high-grade Suppress Vibration Hybrid Mechanism to achieve stalwart stability, eliminate internal and external resonance, and further ensure accuracy.

Equipped with Advanced AL32 Processing Plus – analog-waveform reproduction technology that uses unique data-interpolation algorithms to restore data lost during digital recording – DCD-17000NE plays SACDs and CDs with detailed, expressive, rich sound. You can also spin DVD R/RWs embedded with up to 5.6MHz and 24-bit/192kHz files. No matter the media insert into DCD-1700NE, you will enjoy music with engaging emotionalism and vibrancy.

Weighing nearly 20 pounds, DCD-1700NE comes with a remote control and connectivity that includes a gold-plated analog output, optical output, and coaxial ouput. Pure Direct Mode further speaks to this unit's commitment to audio quality. Simply put, DCD-1700NE is the difference between striving for and attaining gripping performance and settling for what's already been done.

Advanced AL32 Processing Plus
DCD-1700NE features Advanced AL32 Processing Plus, the latest version of Denon's analog-waveform reproduction technology that utilizes unique data interpolation algorithms and also supports high-resolution sound sources. 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. By carefully restoring data 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.

TD-505 Disc Drive with S.V.H. Mechanism
DCD-1700NE's disc drive design contains a high-class S.V.H. (Suppress Vibration Hybrid) Mechanism. Signal paths are shortened to an absolute minimum and circuits miniaturized to ensure that excess current or noise does not occur. The S.V.H. Loader of hybrid construction gives stability to the disc drive so that the disc can be read with utmost accuracy. In addition, the mechanism's low center of gravity suppresses any vibration occurring inside the mechanism due to disc rotation, and the mechanism structure also effectively suppresses external vibration. By eliminating unwanted vibration, servo-related operations are minimized. And by minimizing unnecessary controls and current consumption, digital signals can be read from the disc with optimum accuracy under stable conditions.

Direct Mechanical Ground Construction
The integrity of musical signals deteriorates when the latter are subject to internal vibration caused by disc rotation or the power transformer, or to airborne vibration caused by sound pressure from speakers. To guard against such influences, Denon engineers designed a vibration-suppression structure called Direct Mechanical Ground Construction. In this design, the power transformers – a source of vibration – are placed close to the feet of the DCD-1700NE where unwanted vibration is funneled to the ground and prevented from affecting nearby circuitry. Also, by placing the drive mechanism low in the center of the chassis, the low center of gravity effectively absorbs internal vibration caused by disc rotation and protects the mechanism from external vibration.

DAC Master Clock Design
To accurately synchronize digital circuits, DCD-1700NE's DAC Master Clock Design treats the DAC as the master when clock signals are supplied. Positioning the master clock adjacent to the DAC suppresses jitter and ensures optimum precision in D/A conversion. 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. DCD-1700NE employs a clock oscillator to dramatically reduce phase noise. The clock power circuit is vastly improved to bring out the full potential of the high-quality clock's performance. A conductive polymer capacitor with outstanding high-frequency impedance characteristics is located at the base of the clock's power source, and an ultra-compact film capacitor different from layered ceramic capacitors placed close to the clock to achieve an improved S/N ratio and a transparent sound with superior spatial expression.
