1x pair QED Signature 40, analogue interconnect, RCA-RCA, 3m length.rnrnMint condition in original boxrnrnRRP 399
Timing matters a bit here because this is a long-running QED cable range rather than a current flagship, but that doesn’t hurt value if the condition is genuinely excellent. At £140, it sits well above the usual used GBP market here: the median is £76, the 75th percentile is £85, so this is clearly ambitious rather than a bargain.
What saves it is the product itself: QED’s Signature line is well regarded for a clean, open, lively presentation with good build quality, and a 3m run is practical for real systems. If the termination is original and the cable has been well kept, there’s still appeal here for someone who wants a tidy, reputable interconnect. Still, at this price I’d want confirmation of exact connectors and any proof it’s been stored/usefully handled, because the premium over the market is hard to justify otherwise.
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.
