Offered is „Diamond Ethernet cable in 0.75 m“ by AudioQuest as second-hand device from the category „Ethernet digital streaming cable“ on audio-markt.de - the online market place for high-end. The advert with the number 1882776669 ends on 09.12.2026 at 15:52 o'clock.
Across 18 comparable EUR listings, the median asking price is €661, with the middle half spanning €507–€775. At €700, this sits modestly above median but comfortably below the 75th percentile, so it looks fair rather than ambitious—especially if “good” means clean, complete, and fully functional.
The Diamond is AudioQuest’s premium interconnect, valued for its solid Perfect-Surface Silver conductors, substantial shielding/noise-dissipation measures, and, on relevant versions, the 72V DBS system. It is aimed at revealing systems where source and DAC quality justify a high-end cable, and reported strengths include clarity, precise treble, firm bass, and strong dynamic contrast. Check the exact termination and length, confirm the DBS battery pack is present and working where fitted, and verify connectors are clean; with those basics covered, €700 is a sensible enthusiast buy.

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.
