This is a mature, older-generation cable, so timing only really matters if you want this exact voicing and build rather than chasing the newest release. At £450, it sits a touch below the £479 median and under the £626 upper quartile for recent UK comparables, so this reads as a fair-to-good buy rather than a bargain-basement steal.
That still makes sense for a well-regarded interconnect like this, since the appeal is usually its very low noise, strong detail retrieval, and polished, high-end presentation in a system that already deserves it. A clean example at this price is worth a look; just confirm length, termination, and that both ends are original and undamaged, because with cables the right spec and condition matter as much as cosmetics.
Independent perspective — not a price guarantee. Always verify condition, accessories and provenance before purchase.
Founded in 1980 by Bill Low in Irvine, California, AudioQuest traces its roots to 1978, when Low, a hi-fi store manager and avid enthusiast, began crafting superior audio cables to overcome the signal degradation he observed in existing products. Dissatisfied with subpar materials and construction, he prioritized advanced conductors like 6N copper, innovative insulation, and precise geometries, quickly earning acclaim after demos at events like the 1979 Summer CES. This passion-driven origin propelled AudioQuest from a cable innovator—first U.S. company to advance signal transmission in 1985—to a global force in high-performance audio.
While renowned for its expansive lineup of analog, digital, and AC power cables, including HDMI for video, AudioQuest has broadened into USB DACs and headphone amps, highlighted by the multi-award-winning DragonFly series launched in 2012. The brand also offers Niagara and PowerQuest power conditioners, alongside custom-install solutions, all engineered to maximize system fidelity without venturing into amplifiers, speakers, or turntables.
AudioQuest commands a premium position in the high-end market, supplying thousands of specialist retailers across 60 countries as the dominant cable provider for discerning audiophiles. Its relentless innovation, from conductor purity to dielectric design, delivers tangible performance gains, cementing a reputation for value and musicality that serious hi-fi buyers trust.
