AudioQuest Diamond HDMI Cable

Audioquest designed Diamond HDMI to be the absolute best possible high definition interface available on the market. Built with pure silver conductors, heavily plated silver HDMI connectors and Audioquest's patented Dielectric Bias System, Diamond is the finest HDMI cable we've ever had the pleasure of listening to. Lightning fast, Diamond has explosive speed, truly unleashed dynamic range and a level of dynamic shading unlike anything we've ever experienced. Diamond's timbral accuracy puts other digital cables to shame, with a natural and neutral tonal balance which preserves the intention of any recording.


Diamond uses only 100% pure silver conductors. Extremely expensive to implement, pure silver conductors offer the finest possible conduit for electrical signals. Protected and enhanced by Audioquest's Patented DBS system, the silver conductors in Diamond offer a revelatory insight into any recording. Diamond is a directional cable, AQ listens to every primary signal conductor used in Diamond to determine proper conductor orientation, this simple test yields a surprising improvement to sonic performance. 


Diamond is terminated using a solderless cold-weld process which eliminates distortion and improves reliability and longevity. Diamond receives high-performance silver plated connectors for superior connectivity and signal transfer.  The DBS System is integral to the cable and the batteries need only be checked every 6 months.

HDMI v1.4

While the focus of the Indulgence Series HDMI cables is ground-breaking audio, video performance is hardly an afterthought. All Indulgence HDMI cables are High Speed compliant up to and including 5 metres and all will transfer 1080P/120HZ/4K/3D video. All Indulgence HDMI cables deliver 100% of the data required for 120Hz/240Hz/600Hz displays. All AudioQuest Indulgence series HDMI cables are 100% QC tested to pass 1080p at every length and all contain the 5th twisted pair for the new Ethernet and Audio Return Channel options.

Critical Twist (Half-Speed Mastering) 

Audioquest winds all their HDMI cables at half the speed of other manufacturers; winding the cables slower allows the conductors to be more precisely placed, creating greater consistency, reliability and performance. Solid Polyethylene insulation ensures stable conductor geometry while minimizing insulation induced phase distortion. 

Diamond HDMI will pass 3D video at lengths of up to 10 metres.
