    New AudioQuest DragonFly Cobalt

    The official press embargo is over and we can release details of the new AudioQuest DragonFly Cobalt. Mine arrives on Wednesday via FedEx. I can't wait to connect my cans and give it a workout. Until then, here is the official press release and accompanying information from AudioQuest.

    AudioQuest Introduces High-Performance Portable USB DAC: DragonFly Cobalt 

     

    In 2012, the original AudioQuest DragonFly thoroughly disrupted the DAC market. For so many casual enthusiasts who had never previously considered the possibility of improving their digital-audio experience, DragonFly was nothing short of a revelation. Meanwhile, even the most experienced audiophiles were compelled to reexamine long-held notions of what a DAC could and should be. Stereophile’s Art Dudley enthusiastically summarized, “DragonFly is fun: It’s a thumb in the eye of those tea-pinky tyrants who would tell the rest of us what is and is not high end. I can think of no more recommendable product in digital audio.” 

     

    In the early months of 2015, AudioQuest surpassed its previous achievements with DragonFlys Black and Red—two sensational models that offered improved performance-to-cost ratios with unprecedented sound quality, free firmware updates, and, of course, the biggest news of all, compatibility with Apple® and Android® smartphones. 

     

    And now comes DragonFly Cobalt ($299.95 US)—AudioQuest’s new flagship DAC. Cobalt takes what music lovers around the world have come to expect from the multi-award-winning DragonFly family—naturally beautiful, seductive sound—and strips away fuzz and fog that weren’t even noticeable until Cobalt removed them.

     

    How is this possible? Like the critically acclaimed DragonFly Red, Cobalt has the robust 2.1-volt output to drive almost any headphone, uses a bit-perfect digital volume control for outstanding signal-to-noise ratio, enables seamless compatibility with Apple and Android devices, and is an exceptionally competent and affordable MQA renderer.

     

    Cobalt’s precedent-setting performance is made possible by multiple significant upgrades:

     

    • New, more advanced ESS ES9038Q2M DAC chip with a minimum-phase slow roll-off filter for more natural sound.
    • Microchip’s superb PIC32MX274 microprocessor draws less current and increases processing speed by 33%.
    • Improved power-supply filtering that specifically increases immunity to WiFi, Bluetooth, and cellular noise.
    • Includes AudioQuest’s new DragonTail USB-A (female) to USB-C (male) adaptor to easily accommodate the increasing number of electronic devices that feature USB-C ports. 
    • Contoured enclosure measures just 2.26” x 0.73” x 0.47” (57.5mm x 18.6mm x 11.9mm), making the latest DragonFly 10% smaller than its predecessors.

     

    Like previous models, Cobalt uses Gordon Rankin’s precedent-setting StreamLength® asynchronous-transfer USB code. Further, in Gordon’s monoClock® technology, a single ultra-low-jitter clock generated from the ESS ES9038Q2M DAC chip runs the ESS chip functions as well as all microcontroller functions. This superior clock enables DragonFly Cobalt to provide greater resolution and clarity than DACs with multiple clocks.

     

    With AudioQuest’s DragonFly USB DAC, music appreciation and exploration are limitless: Plug into an Apple or Windows® computer or connect to an iOS® or Android mobile device. Play YouTube or Vimeo videos. Go hunting on Bandcamp or SoundCloud. Explore playlists on Spotify or Pandora. Stream high-res audio from Tidal or Qobuz. No matter the choice of musical pleasure, DragonFly delivers beautiful sound to earbuds, headphones, desktop speakers, or complete audio systems, unraveling the emotional expression and nuance that makes music and movies so enjoyable. Now, more than ever before, naturally beautiful sound is right at your fingertips—however you want it, whenever you want it. 

     

    The first 10,000 units of DragonFly Cobalt will come packaged with vouchers for trial subscriptions to the outstanding Tidal and Qobuz music-streaming services. Cobalt customers can begin their musical journeys with two new AudioQuest playlists—On an AudioQuest and Making Connections—available on Tidal and Qobuz, respectively.

    I have a more question about usability. What exactly happens when we are listening to music with the dragonfly cobalt and we have a incoming call and we want to listen to it. Does the DAC (1) silence the music automatically (2) pass trough our sound, if the headphones have mics...

    On the iPhone the Cobalt (or the Red) will not be seen at all by the phone when it comes to calls. If you receive a call, you will have to pick up the phone as you would if you had nothing connected to it, the earpiece and microphone in the phone would be the ones used. You don’t need to disconnect the Dragonflys to pick up a call. I would expect the same behavior with all USB-connected DACs.

    I'd love to upgrade. Anybody interested in buying my Red?

    Definitely an upgrade. Better than Jitterbug+Red (which I use on my Macpro).

    Thanks. I may just be too lazy to find a buyer for my Red. I’m not good at the reselling business.

    I was as well. Superphonica here has been great, sold two items already - simplifies the whole process. I am keeping my Red probably just to leave on my macpro.

    About 60% of the slider in Audirvana give or take, for all my headphones

    The current supplied to the load has to come from somewhere.

    @Archimago makes a reference to the "Wowza" hype review articles from Headphonia, Darko.Audio, MajorHiFi, Audio Advice, Hi-Fi+, and The Audiophiliac Guttenberg.  I have never found the reviews from those mentioned to be useful except to point out features (usually found in the manufacturer's press releases) and to provide nice pictures.  If they are not shills, they really should be.

    Thx @Archimago for this analysis. The clipping at 100% volume is a really bad bug if it is common to all units. Jeez... I compared the Cobalt to the Red with my headphones only - HD600/HD650/AKG K701/AKG K702/Denon AH-D2000/Noble Kaiser 10 custom IEMs. Obviously never hit 100% volume. I found the Cobalt to sound a bit smoother and punchier than the Red frankly, or should I say I found the Red to be slightly more “grainy on the highs” for lack of a better description. I did find - as mentioned elsehwere - that the Cobalt draws more, not less current, so more power, which is in line with it being more punchy I suppose.

    Mine clips at full volume only with a load of 5 kΩ or less, so there's apparently some variability. It's still bad.

    Archi says if you run it at 98% volume you get around the problem. So not so serious, IMO. The more serious issue is if the $300 version is not as good on only just as good as the $200 one.

    Or the $100 one, in some cases.

    I would regard this as an awful bug. Having said this, it is good to know that with a high impedance load (>5kOhm) it doesn’t clip. In most cases where you’d want to set the volume to 100%, you’d be going to an additional amplification stage, and most those would be pretty high impedance (>>5kOhm). Thx for checking this.

    I think this is a pretty darn awful bug, frankly. WTF???

    Archimago's sample clips even with a 1 MΩ load. There appears to be some variation in production.

    Saw a firmware update for both Cobalt (v1.10 latest) and Red (v1.07 latest). 

     

    Anyone tried this? Any differences?

     

    Thx.

    Haven't tried it yet. We will publish two reviews of the Cobalt this week. One subjective and one objective.

    No mention of a Cobalt update on the AQ website.

    I run the updater on Mac and it said there was an update to v1.10. This might actually be wrong, as I also run it for the Red and said there was an update from v1.06 to v1.07 - but v1.07 is fairly old (I just realized this), and I have surely updated to v1.07 whenever it came out (I am a serial updater... :) ).

     

    What firmware is reported for your Cobalt on the AQ app?

    I haven't checked, but the 'bcdDevice' field in the USB device descriptor says 1.10. That field matches the firmware version on the Black.
