Super Audio CD Player (2005-10)
The DCD-1500AE features AL24 Processing, an analogue waveform reproduction technology that Denon developed to reduce quantitative noise and support the higher resolutions and sampling of next-generation media.
AL24 Processing interpolates the recorded digital data so that it produces a waveform that is closer to the analogue waveform for the sound as it existed in the natural world. By reproducing in 24-bit quality the 16-bit signals recorded on CD, low-level signals such as those that occur at moments when the music quietly fades or starts are reproduced with greater clarity.
The DCD-1500AE includes the Original Drive Mechanism that Denon has been perfecting over many years for both dedicated and universal CD players. The three-phase brushless spindle motor has been designed with an extremely short shaft that not only suppresses mechanism resonance caused by high-speed rotation during Super Audio CD playback but also suppresses internal resonance caused by disc eccentricity, to create an ideal servo environment.
This design ensures superior disc reading accuracy and playability. It also incorporates a highly-acclaimed SVH (Suppression Vibration Hybrid) loader that features a hybrid construction combining multiple types of materials to further improve the disc drive's stability.
A 24-bit D/A converter is used to perform D/A conversion. High sound quality is made possible with an extremely simple configuration that uses only a pure analogue FIR filter in the output stage of the D/A converter. This D/A converter uses differential operation for each of the two stereo channels to further boost sound quality.
As in Denon's higher-end models, the DCD-1500AE uses the DAC as a master to supply clock signals to the various devices and ensure highly reliable oscillation accuracy. By frequency dividing signals from the master clock at a dedicated device, the DSD decoder that is vital for Super Audio CD playback and the DSD clock signal effectively minimize the adverse influences of jitter to achieve sound images with clear contours.
The unit includes a Pure Direct mode that turns off the display and digital signal output. When the pulse signals of the digital data and the display drive are turned off, adverse influences on the audio signal are eliminated to create a more favourable environment for enjoying the purity of music.
