Cobalt is the new RED! Yes, the new color is Cobalt blue, and the unit has an automotive finish with silver lettering. Like before the DragonFly has a protective endcap, a contoured enclosure and it also comes in a leatherette travel pouch. It’s a nice package, and it gets even better as you now also get a DragonTail USB-C adaptor! All DragonTails use AQ’s Carbon-level USB cable.
Design wide the new Cobalt doesn’t look like the RED and Black anymore and with it’s smoother lines it looks smaller and more sexy.
The DragonFly Cobalt’s native resolution still goes up to to 24-bit / 96kHz and it has the same 2.1V output like the RED. It’s a direct-coupled, high output which supplies enough power to easily drive the widest range of headphones. When used as a line-level device (volume set to 100%), DF Cobalt’s 2.1 volts provide enough power to drive all preamplifiers, integrated amplifiers, or receiver inputs.
The headphone amp used is the same one as the one in the RED version, the ESS Sabre 9601. The microchip now is the PIC32MX274 and it has the same features as Red and Black, but reduces current draw and increases processing speed by 33%. Impressive!
The DAC Chip in the Cobalt is the ESS ES9038Q2M, with minimum-phase slow roll-off filter for more natural sound. The RED uses the ESS ES9016 and the Black the ESS ES9010. It’s evolution!
The Cobalt comes with an improved power-supply filtering, specially designed to reduce WiFi, Bluetooth, and cellular noise. Of course you can still use the Cobalt with your desktop pc, portable PC and your mobile and it still offers MQA rendering! (see video above)
Size-wize the Cobalt is a tiny bit smaller and it measures 12mm (h) x 19mm (w) x 57mm (l). The RED and BLACK measure 12mm (h) x 19mm (w) x 62mm (l)
The Cobalt’s price has been set at $299€ or £269. It’s more but it’s newer, better and you get a DragonTail USBC to USB adapter on top of it
Full DragonFly Comparison
AudioQuest has been so kind to publish a clear overview of all the available DragonFly models and you can find that here: DragonFly Cobalt_ComparisonChart_white_6.20.19
The amplifier section is the same so it all comes down to the faster processor, better power supply and especially the new DAC section.
The first things you notice is how clean and clear the new Cobalt is delivering the sound. And not only that, it does it without any effort making it sound wide, natural and realistic.
Compared to the RED, the Cobalt sounds better, more precise, more wide and spacious but also more natural and clean. The separation is better, the sound stage wider, the extension better in all directions and the presentation more airy. Bass is a bit less thick, the mids more spacious, the treble more energetic and further extended. The Cobalt is superior to the RED on a technical level. Red is more punchy, more in your face, the mids more narrow/intimate, the treble less present.
The tuning is more neutral but to the natural and musical side. The Cobalt can’t be called a warm or dark sounding unit at all, it’s nothing like that. It’s neutrality with a high level of musicality and presented in a natural way with a lot of headroom.
I’ve been listening to it mostly with the brand new Vision Ears Elysium as well as the Earsonics EM64 and it’s dead silent with a pitch black background. Changing the volume of the Cobalt (64-Bit Bit-Perfect Digital Volume Control) is also perfectly noiseless.
I’ve been going back an forth between the RED and Cobalt using the transfer zone function in ROON, and after a lot of listening and switching, I have to say I really do prefer the Cobalt over the RED. In this case for me it’s clear already: the Cobalt really is an improvement of the RED.
Now does it mean you need to upgrade? No, not really as the RED still is really good as well. The Cobalt is a bit better though, and if you like technicalities you’ll for sure prefer the latest version. Some on the other hand will prefer the typical tuning of the RED over that of the new Cobalt. The Cobalt should be at your dealer very soon so I advise to go check it out and demo it. Take your Black or RED with you and do the test yourself.
We’ll of course do a lot more listening and testing with the Cobalt before we publish the full review, but it’s safe to say that AudioQuest with the Cobalt has another winner in their hands. One which audiophiles like us will enjoy for years.
Full review soon, but for now it’s all looking good. Well done AudioQuest.
