To faithfully reproduce the original sound, the DCD-520AE is endowed with a wide range of audio technology that Denon has developed & 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 & 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 & achieve low impedance. Denon engineers used rigorous listening tests to select the DCD-520AE’s high-precision 32-bit/192 k Hz D/A converter. This converter & the audio circuit design that Denon has developed over many years masterfully reproduces the delicate nuances of music in the audio signal.
