The Diablo 2 is the world’s first portable DAC/Amp with Bluetooth 5.4, it supports aptX Lossless, the only Bluetooth codec for lossless CD-quality streaming without sacrificing audio quality.The predecessor of Diablo 2 pioneered support for xMEMS solid-state micro-speaker technology, enhancing IEM and headphone performance with several unique benefits:A 15µsec mechanical response, 150 times faster than typical drivers.A 2° flat phase response for precise sound and precise +/- 1° phase matching for enhanced spatial sound accuracy.A speaker diaphragm made of silicon, 95 times stiffer than plastic, reducing speaker break-up and delivering clearer mid-high frequencies.Due to the high voltage requirements of xMEMS, iFi has partnered with them to integrate this technology into the new Diablo 2. It utilises the piezoelectric effect to create paper-thin solid-state speakers by converting electrical energy into mechanical energy, exciting an integrated silicon membrane to generate powerful acoustic sound waves for enhanced audio output.Click here to read more about the xMEMS earphones application.“It’s got a NOS fogger system and a T4 Turbo, Dominic.”Struggling with your power-hungry headphones? Press the NOS button, and our Diablo goes into beast mode. The Diablo 2 offers three power modes: Normal for IEMs, Turbo for mid-sensitivity headphones, and Nitro for demanding headphones, boasting a 19.2V maximum output.A switch underneath activates iFi’s iEMatch technology. This feature is tailored for high-sensitivity headphones and earphones, greatly benefiting your in-ear monitors (IEMs). It removes background noise and increases the usable volume range.The Diablo 2 accommodates a wide range of headphones, from IEMs to power-hungry over-ears. It features a 6.3mm single-ended headphone socket and a 4.4mm balanced output. Additionally, a 3.5mm to 6.35mm adapter is included for versatile connectivity.Ruling all Bluetooth codec and music formats.The Diablo 2 features the latest Bluetooth 5.4 technology, supporting the new aptX Lossless codec, which provides a maximum bitrate of 1,200kbps.

DirectDrive removes the need for coupling capacitors, ensuring purer audio.OptimaLoop employs tailored multiple feedback paths in amplifiers, refining gain control and reducing distortion. The enhanced GMT femto-precision clock with Smart storage cache minimises phase noise for cleaner sound.Diablo 2 is the most formidable DAC/Amp on the planet. Your headphones should be scared.Diablo’s Energy SourcesThe Diablo 2 can be powered by battery or mains.Battery power provides ultra-clean and stable DC current, avoiding mains electricity issues like dips, spikes, and noise inducing RFI/EMI pollution. However, there are sonic downsides due to low output voltage and inconsistent output impedance as batteries discharge.The bundled iPower2 power supply features Active Noise Cancellation II, effectively cancelling out all incoming EMI and RFI noise and making it more than 10 times quieter than most audiophile power supplies.To make less efficient headphones, like planar magnetics, sing, the voltage needs to be stepped up from 3.7V to +/- 15V. We use a step-up converter operating at 1.2MHz – a frequency far beyond audibility and easier to filter than a typical switch-mode supply, ensuring high linearity and ultra-low noise.

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 a form-fitting DragonTail female USB-A to male USB-C Adaptor.All DragonTails use AQ's Carbon-level USB cable. AUDIOQUEST, GORDON RANKIN: A BEAUTIFUL PARTNERSHIP Like all previous DragonFly 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. WHY THE "SLOW ROLL...?" Cobalt employs ESS's new flagship ES9038Q2M DAC chip. While the chips used in DragonFlys Black and Red are unbeatable for the price, the minimum-phase slow roll-off filter in the 9038 results in naturally expressive sound that is always emotionally engaging and never fatiguing—a beautiful combination of warmth and detail that we find equally exciting and soothing. KILLING THE NOISE In Cobalt, we've taken what we've learned from our recent research and development in noise dissipation to employ power-supply filtering specifically designed to dramatically reduce the increasingly prevalent noise from WiFi, Bluetooth, and cellular signals. Successfully combating this noise is absolutely crucial to the preservation of the lowest-level musical details, particularly when it comes to high-res audio—and especially when applied to a portable-audio device such as DragonFly. BIT-PERFECT VOLUME CONTROL AND 2.1-VOLT OUTPUT Cobalt features the same ESS Sabre 9601 headphone amp and bit-perfect volume control that give DragonFly Red its unique combination of power and grip over the music. This solution ensures maximum fidelity, thrilling dynamic contrast, and excellent signal-to-noise ratio. The 2.1-volt output makes Cobalt and Red compatible with a wide range of headphones, including power-hungry, low-efficiency models. FIRMWARE UPGRADEABLE DragonFlys Black, Red, and Cobalt are firmware upgradeable via our free Desktop Device Manager. In today's fast-paced digital world, longevity in a hi-fi component is increasingly rare—at any price.
