AudioQuest is an American audio and video accessories company founded in 1980 by William E. Low and based in Irvine, California. The company began when Low, running a small hi-fi shop, started building custom audio cables, and it has since grown into a global brand distributing to dealers in dozens of countries with additional offices in the Netherlands. Its stated design philosophy centers on minimizing signal distortion rather than trying to improve the signal itself.

AudioQuest is best known for analog interconnects, speaker cables, and digital cables (HDMI, USB, Ethernet, and optical), along with power conditioning gear in the Niagara and PowerQuest lines. Cable families such as Rocket, Pegasus, and the flagship Dragon are long-standing fixtures in the high-end hi-fi world, and the company makes turntable accessories and phono cables aimed at vinyl listeners.

The brand is also widely recognized for its DragonFly line of portable USB digital-to-analog converters (DragonFly Black, Red, and Cobalt) and the JitterBug USB noise filter, products that brought AudioQuest into the headphone and computer-audio market beyond its traditional cable audience.

AudioQuest has 6 products cataloged on Equipboard, including Power Conditioners, Recording Snakes, and Home Headphone Amps & DACs.
