Against recent used GBP comparables, £260 sits well below the £412 25th percentile and far under the £479 median, so this looks like a strong buy rather than merely fair. It is not just cheap; it is cheap relative to how these usually trade, which makes it stand out as a genuine bargain if the listing is genuine and the length/termination match what you need.
This is one of AudioQuest’s better-known interconnects, valued for a clean, low-noise, highly resolving presentation that suits revealing systems. The upside here is simple: if the cable is authentic and in good shape, you’re getting a premium-tier interconnect at a price that leaves a lot of room versus the market, with no special caveats needed beyond the usual check for correct connectors, intact sleeving, and unmolested terminations.

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.
