Audio quality is a core focus, with full support for Dolby TrueHD and DTS-HD Master Audio, delivering an immersive cinematic experience. The cable is HDCP compliant, ensuring seamless playback of encrypted content from Blu-ray players and streaming services, and features an Audio Return Channel (ARC) for synchronized audio-video transmission. Build quality is exceptional, featuring a full copper construction with tin-plated copper wire cores.
