AudioQuest Spreads its wings with their USB DAC
AudioQuest, the high-quality audio and video cable manufacturer, is speading its wings into high quality audio from portable and home computers. DragonFly is AudioQuest's cool new USB Digital Audio Converter (DAC) for your stored digital music.
High-Fidelity Sound … From Any Computer
Today’s computers are a digital hub capable of delivering a nearly infinite amount of Internet- and computer-based music and video content. However, with their tiny budget, the analog and digital audio circuits in your computer are not designed with the quality of parts and sophistication of circuitry which would enable the computer to perform as a high-fidelity audio source component, fully honoring the fragile nature of audio data. DragonFly is an affordable and easy-to-use sonic solution that delivers far superior sound by bypassing the computer’s built-in sound card.
DragonFly is a sleek, flash drive sized Digital-Audio Converter (aka, “DAC”) that connects to a USB jack on a Mac® or Windows® PC, turning any computer into a true high-fidelity music source. Whether you’re on the go or at home, listening to ear buds or connecting your computer to a stereo system, DragonFly lets you hear all the emotional expression and nuance that makes your favorite music, or movies, so enjoyable.
