The AH-D9200 comes with two high-grade audio cables for listening on multiple systems. Both detachable cables have undergone extensive testing in the Denon Shirakawa facility to ensure the highest quality for audio and the longest life. Use the finely crafted 3.0m cable with 6.3mm silver-coated jack with your HiFi system, or 1.3m OFC cable with 3.5mm plug from your portable digital audio player. The natural electric conductivity of silver creates a pure signal transfer and helps balance sound in high-frequency audio — listen with impeccable accuracy and quality.
