AudioQuest - DragonFly Black
xxx Brand: Audioquest
Product Code: AudioQuest - DragonFly Black
Please note: Due to unprecedented demand, there are delays in shipping both DragonFlys Black and Red. Please be irritated with AudioQuest rather than with your dealer as we work to fill backorders as quickly as possible. Thanks for your patience.
The Original DragonFly
Launched in 2012, press and public alike have enthusiastically embraced AudioQuest’s multi-award-winning DragonFly USB digital-to-analog converter/preamp/headphone amp as the rare audio product that bridges the gap between die-hard audiophiles and mainstream music lovers.
DragonFly plugs into a computer’s USB port to bypass the computer’s compromised audio circuitry and deliver cleaner, clearer, more naturally beautiful sound to headphones, powered speakers, and complete audio systems.
Small, affordable, easy to use, and remarkably effective, DragonFly was named Stereophile’s 2012 “Computer Audio Component of the Year” and 2012 “Budget Component of the Year;” Tone Audio’s 2012 “Digital Product of the Year;” Computer Audiophile’s 2012 “Computer Audiophile Product of the Year;” AudioStream’s “Greatest Bits;” and What Hi-Fi?’s 2014 “Product of the Year.”
Perhaps most memorably, DigitalAudioReview.net’s John Darko quipped: “A DAC with the DragonFly’s performance at the DragonFly’s price point is as rare as rocking horse sh*t.”
We couldn’t have said it better.
The Next Generation: DragonFly Black & DragonFly Red
While the original DragonFly defined the market for micro-DACs, its USB power draw made it compatible with computers only. Music lovers have craved a more portable version—one that could be reliably used with Apple and Android smartphones and tablets.
We’re delighted to present two new options that do just that: DragonFly Black and DragonFly Red.
Convenience and performance are no longer mutually exclusive. With DragonFly Black and Red, any computer, laptop, tablet, or smartphone can be used as a true high-fidelity music player, allowing music lovers to enjoy beautiful sound wherever they go, whenever they please.
AudioQuest, Gordon Rankin, and Microchip: A Beautiful Partnership
AudioQuest and DragonFly designer Gordon Rankin worked alongside Microchip Technology to develop a new high-performance, full-speed USB microcontroller solution that delivers improved signal-to-noise ratio and significantly lower power consumption.
Drawing 77% less current than the previous microcontroller, the new Microchip PIC32MX microcontroller enables true compatibility with Apple and Android smartphones and tablets.
Further, we simply cannot overstate the significance of Gordon Rankin’s contributions to AudioQuest. The new DragonFly models embody many of Gordon’s most innovative, creative, and elegant digital-audio solutions to date.
Improved 32-Bit Digital Performance
For greater overall performance, the new DragonFly models also incorporate improved 32-bit ESS Sabre DAC chips—the 9010 in Black and the higher-performance 9016 in Red—both of which employ minimum-phase filtering for naturally detailed, more authentic sound. While DragonFly Black uses the same high-quality headphone amp and analog volume control found in DragonFly v1.2, DragonFly Red includes the latest ESS headphone amp and a bit-perfect digital volume control that resides on the 9016 DAC chip itself—a sophisticated implementation that ensures maximum fidelity, dynamic contrast, and signal-to-noise ratio.
DragonFly Black will output 1.2 volts—enough power to successfully drive all preamplifier input circuits and a wide range of today’s efficient headphones. Meanwhile, with its higher 2.1-volt output, DragonFly Red will be compatible with a wider range of headphones, including power-hungry, low-efficiency models.
While the DAC chips we’ve selected are remarkably powerful and sophisticated, we’ve intentionally limited DragonFly Black and DragonFly Red’s processing capabilities to 24-bit/96kHz resolution. This makes using the DragonFlys as simple as it’s always been: they’re fully compatible with PCs without having to download and install new drivers.
Most importantly, DragonFly is designed to honor the music you already own and love. Whether you’re listening to Spotify, YouTube, Tidal, ripped CDs, or state-of-the-art high-resolution files, DragonFly will deliver a more emotionally compelling and enjoyable experience.
Free Desktop Application for Software Upgradability (for DragonFly Black and Red only)
In addition, the new DragonFlys will be software upgradeable through a complimentary Windows or OS X desktop application. As new developments arise in music player applications, streaming protocols, or other associated software, DragonFly users will be able to incorporate those updates to their existing devices.
Only the Beginning
Introduced to the media at the 2016 Consumer Electronics Show, DragonFly Black and DragonFly Red were named “Stars of CES” by What Hi-Fi? Magazine. But this is only the beginning.
We look forward to building stronger, more meaningful connections between music enthusiasts and the artists, albums, songs, and videos they love. Our hope is that with DragonFly Black, DragonFly Red, and future AudioQuest digital products, more people than ever before can enjoy beautiful music—wherever they go, whenever they please.
