British firm QED must surely be the first specialist high-fidelity audio cable company in the business. It started way back in 1976 with a speaker cable. Back in those days, people often used astonishingly thin and inefficient wires for their speakers.
Since then, QED has broadened its portfolio to include a full range of analogue audio and digital interconnects, including optical and HDMI.
QED is distinguished from many other cable specialists by surprisingly reasonable pricing for its entry level range. And for offering products that can solve difficult problems for some installations, such as the active HDMI cable which supports 8K @ 60Hz, 4:4:4 resolutions, available in lengths of up to fifty metres.
