QED X-Tube, XT-40 Aircore Speaker Cables 3mt Pair of QED XT40 Reference Speaker Cable with X-Tube Technology, terminated with Airloc Banana Plugs. Copper cable 99.999%. Wire gauge 12 AWG. What Hi-Fi?

Priced at A$185, this like-new QED Performance Digital coaxial cable is significantly overpriced compared to the typical used market, where the median sits at A$67 and the 75th percentile caps out at A$90. The asking price is more than double the 75th percentile and nearly triple the median, making it an ambitious listing that fails to reflect standard value for this product line in Australia.
While the QED Performance Digital series is well-regarded for its robust construction and reliable signal transmission in digital audio setups, paying A$185 for a used cable offers no meaningful upside to justify the cost. Unless this listing includes rare custom lengths, original packaging, or a significant warranty not typical for used units, it represents a poor buying opportunity compared to the abundant A$52–A$90 range available from other sellers. Save your money and look for a unit closer to the A$67 median.
Independent perspective — not a price guarantee. Always verify condition, accessories and provenance before purchase.
QED: British Audio Cable Pioneer
Quality Electronic Design was founded in 1973 by Bob Abraham and Ian Vine, establishing itself as a British specialist in audio and AV connectivity. The company emerged from a philosophy that cables deserve serious engineering attention—a radical notion at the time. QED's landmark 79 Strand cable, released in the mid-1970s, became widely recognized as the world's first specialist loudspeaker cable and fundamentally shifted industry perception by demonstrating that cable design could measurably impact audio performance.
QED's product portfolio centers on audio and audiovisual cables and connectivity solutions. The brand has built its reputation through rigorous engineering principles, extensive measurement protocols, and computer-aided design techniques applied across speaker cables, interconnects, and related components. This scientific approach has earned the company numerous industry awards and established it as the market leader in premium cable design.
Positioned in the high-end and mid-tier segments, QED commands respect among knowledgeable audiophiles and home cinema enthusiasts who prioritize technical rigor and proven performance. The brand occupies a unique space as both a heritage player with five decades of innovation and a contemporary technology leader. QED remains headquartered in the UK and maintains distribution internationally, appealing to buyers who view cables as legitimate audio components worthy of investment rather than commodity items.
