QED was founded in 1973 by Bob Abraham and Ian Vine. Over the years, the two partners have constantly revolutionized their favorite fields, radically changing the perception of individuals of Hi-Fi c bles. It is now assumed that audio/video content in a hi-fi or home cinema system is as important as an amplifier or speaker. In order to better understand the importance of a plant, it is best to translate the situation into another field: that of the automotive industry. The logic is that since you do not equip a small city car with Formula 1 wheels, why should you do the opposite? With a hi-fi or home cinema system, it's the same. The quality of a cble always affects the rendering of an installation, and this QED has understood it well. As early as 1978, the manufacturer marketed its loudspeaker system, and there was a general awareness of the essential role that connectors play in a system.
