What's unique about the brand

QED, founded in 1976 with the world's first specialist speaker cable, pioneered the idea that cables could significantly impact audio performance. The brand's X-Tube technology places conductive material around a hollow insulating rod to eliminate the 'skin effect,' while their cables use premium materials like Ultra-Pure Ohno Continuous Cast Copper and 99.999% oxygen-free copper to improve signal quality.
