To faithfully reproduce the original sound, the DCD-520AE is endowed with a wide range of audio technology that Denon has developed and refined over the years. For a sound that surpasses the quality expected in its class, Denon engineers have carefully selected parts for the audio section, the power unit and other areas on the basis of their contribution to high sound quality. The patterns for the digital circuits have been specially designed to provide maximum protection from unwanted radiation and achieve low impedance. Denon engineers used rigorous listening tests to select the DCD-520AE?s high-precision 32-bit/192 kHz D/A converter. This converter and the audio circuit design that Denon has developed over many years masterfully reproduces the delicate nuances of music in the audio signal.
