and extremely low-noise power supplies, the Microchip® microcontrollers achieve
unprecedented levels of eciency and signal-to-noise ratio, regardless of bit- or
sample-rate. Meanwhile, signicant advances in DAC chips have allowed us to surpass
the performance of even our multi-award-winning DragonFly Red.
DragonFly Cobalt uses monoClock® technology and the StreamLength® asynchronous
USB code*.
With monoClock® technology, a single ultra-low-jitter clock generated from the ESS
ES9038 DAC chip runs the ESS headphone amplier as well as all microcontroller
functionalities. This single ultra-low-jitter clock enables DragonFly Cobalt to produce
greater resolution and clarity than DACs that employ multiple clocks.
StreamLength® asynchronous USB code ensures improved delivery of the audio
samples to the DAC chip. It produces low jitter, low resource load, minimal packet
errors, world-class audio playback, and reliable connectivity between our DAC
and any computing device compliant with USB Host Mode (as set forth by the USB
Organization). StreamLength® is compatible with the USB Audio Class (UAC) and
requires no additional drivers, making DragonFly virtually plug-and-play for Apple™,
Windows™, iOS™, and Android™ users.
Additionally, DragonFly is software upgradable. In today’s fast-paced digital world,
longevity in a hi- component is increasingly rare—at any price. AudioQuest believes
that today’s digital devices should evolve as technology itself evolves, thereby delivering
musical pleasure for many years to come. With our free Desktop Device Manager
