Unknown condition makes the price harder to judge, but at USD 120 this is a strong deal against the supplied market: below the USD 126 median and comfortably under the USD 110–166 middle range’s lower quartile threshold. If it powers up cleanly and includes the DragonTail adapter, the asking price looks like a bargain rather than merely fair.
The Cobalt remains a capable pocket DAC/headphone amp, with a refined ESS implementation, low output impedance, useful drive for many portable headphones, and compatibility with phones and computers. It supports PCM up to 24-bit/96 kHz and can also serve as a variable line output. Check for intermittent USB or 3.5 mm connections, confirm the indicator LEDs and playback, and verify the adapter is present—but at USD 120, even a cosmetically worn example deserves attention if fully functional.
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.
