Against your recent comparator set, £50 lands below the 25th percentile of £54, so this reads as a strong deal rather than just a fair one. It also sits well under the £80 median, with enough margin that a buyer has some cushion even if the market for this sort of accessory is a bit niche.
What makes it worthwhile is the utility: it’s a purpose-built comparator for checking how different amplifiers stack up in the same system, which is exactly the kind of box serious hobbyists use when they want quick, controlled comparisons. At this level, the main upside is simple: useful specialist kit at a sensible entry price, especially if it’s complete and working cleanly. If condition is genuinely unknown, I’d still want a quick confirm on switches, sockets, and channel matching before committing.
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.
