Audioquest Dragonfly Copper USB DAC

AudioQuest DragonFly Copper – Portable 32-bit USB DAC, preamplifier and headphone amplifier

Product overview and audiophile standards

Since the launch of the first generation in 2012, AudioQuest's DragonFly series has stood for the symbiosis of ultra-compact form factor and uncompromising sonic performance. Over 300,000 units sold worldwide and top ratings in leading international hi-fi magazines, as well as recommendations in renowned publications such as the New York Times and Rolling Stone, attest to the technological success of this concept.

The AudioQuest DragonFly Copper continues this legacy. It elevates mobile digital-to-analog conversion to a new level through targeted material evolution and optimized circuit designs – developed for music lovers who demand sonic fidelity as standard.

Technological Evolution: Efficiency meets pure dynamism

The DragonFly Copper was designed for discerning listeners who want to experience the full signal integrity of their audio sources, whether on the go or at work. At the heart of its architecture is a newly developed 32-bit ESS Sabre DAC with an integrated headphone amplifier . This combination delivers significantly increased output power—twice that of its predecessors. This ensures a stable power supply and precise control of even demanding, high-impedance headphones, while simultaneously maximizing sonic detail resolution.

Alongside the performance increase, energy efficiency has been optimized: A highly advanced microprocessor from Microchip Technology reduces power consumption by 25% . This noticeably conserves the battery resources of connected mobile devices and guarantees long, uninterrupted listening sessions on smartphones and tablets without compromising the thermal stability of the transducer. At the same time, the optimized component architecture ensures a reliable and stable supply chain.

Innovative RF protection through copper plating

A crucial factor for the audiophile purity of the signal is the consistent elimination of high-frequency (RF) interference. The DragonFly Copper's housing features a highly conductive, copper-clad structure . This technology, inspired by the RF-dissipating sheaths of the high-end AudioQuest Mythical Creatures cable series, acts as an effective shield against electromagnetic interference. The physical result is a drastically reduced noise floor, minimized distortion, and a deep, clearly defined soundstage with maximum dynamics.

Universal connectivity and intuitive integration

The converter fully complies with the stringent USB Audio Class (UAC) standards. For the user, this means maximum interoperability in the sense of true plug-and-play: no additional driver installations are required. The DragonFly Copper works seamlessly with Apple® and Windows® PCs as well as directly with iOS® and Android™ devices. It processes all common audio formats – from standard MP3s to high-resolution Hi-Res audio streams .

Volume control is direct and precise via the respective source device (smartphone, tablet, or computer). Thanks to its versatile output stage, the DragonFly Copper not only drives headphones with ease but also delivers a clean, high-level signal for preamplifiers, integrated amplifiers, or active speaker systems.
