The DVD-A1UD lets you play Blu-ray discs at the very highest level but the unit also offers Super Audio CD (SACD), DVD-Audio, DVD-Video and CDs in the impeccable picture and sound quality that is expected from a Denon player. With the combination of the newly developed, proprietary 4th generation Denon Link in conjunction with HDMI transmission technology, digital signals from discs can be transmitted with negligible jitter to produce a pure, high-quality sound, and the world’s first fully-balanced two channel transmission in a Universal Player has been made possible for analogue signals.
