As Onkyo's first 1080p upscaling Super Audio CD and DVD Audio/Video player, the DV-SP506 is built on a platform of robust, performance-focused A/V processing and HDMI capability. HDMI is the pipeline through which your DVDs are transformed all the way to high-definition video quality. The DV-SP506 also delivers multichannel PCM audio and Direct Stream Digital (DSD) over HDMI. To enhance audio quality and system integration, the player draws on two proprietary Onkyo technologies VLSC and RIHD. Audio quality is further boosted by three high-end Burr-Brown audio DACs and an internal design that suppresses harmful vibrations.
