Portable Headphones Amplifiers

Devilishly brilliant The iDSD Diablo, with its sleek new design and fiery red finish, sits proudly at the top of our range of portable/transportable DAC/amps. It is built for purists – the true headphone enthusiasts who crave pure, unadulterated sonic performance. Just like a racing car designed for uncompromising speed, the iDSD Diablo sets aside sonic tailoring as well as Bluetooth connectivity to focus on pure sonic power. Prepare for a riveting ride as it will drive any headphone on the planet with aplomb. Put simply, the iDSD Diablo is our best ever transportable amplifier designed to deliver reference level sound. ‘Bit-perfectly’ wicked We use two Burr-Brown DAC chips and the new 16-core XMOS chip to process the data received via the USB and S/PDIF digital inputs. This means the iDSD Diablo can handle up to PCM 768, DSD 512, 2xDXD. Both PCM and DSD remain ‘bit-perfect’. It also provides full MQA decoding! Check out our MQA set-up tutorial (using the highly acclaimed NEO) for Tidal, Roon and Audirvana Positively pure Balanced, differential analogue circuit design reduces noise and cross-talk within the signal path by fully separating the left and right channels. The iDSD Diablo benefits from further refinements to our balanced, symmetrical dual-mono topologies with short, direct signal paths. We call this PureWave. Negative feedback is used in amplifier circuits to compare the output signal with the input signal and correct errors. BUT there are drawbacks. iFi turns the negatives into positives with OptimaLoop. Read more on these technologies below. Diabolically dynamic Able to drive all manner of headphones with ease, the iDSD Diablo delivers up to 5000mW of prodigious power, propulsive energy and engaging dynamics, coupled with a remarkable ability to resolve fine texture and detail. With 3 settings, you can adjust power and gain to suit your daily driver or track day supercar! Turbo – ramps up the level of drive for current-hungry headphones Normal – for most over or on ear headphones Eco – dials down the power to suit high-sensitivity in-ear monitors The iDSD Diablo’s focus on pure, unadulterated performance, means much attention has been applied to the power supply circuity. Battery power provides ultra-clean and stable DC current avoiding the issues of mains electricity – dips, spikes and noise-inducing RFI/EMI pollution. BUT there are sonic downsides resulting from low output voltage and inconsistent output impedance as batteries discharge. These issues are fully tackled by the iDSD Diablo’s design. In order 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 running at 1.2MHz – a frequency far beyond audibility that is easier to filter than a typical switch-mode supply, enabling high linearity and ultra-low noise. Formula 1, iFi style. High-bandwidth power supply circuity is dedicated to each critical part of the iDSD Diablo’s design, with independent linear regulation delivering excellent PSRR (Power Supply Rejection Ratio) performance. The headphone amp stage eschews IC regulators in favour of Panasonic OS-CON capacitors, delivering 2320uF between them. The DAC section benefits from an ultra-low-noise regulator with additional passive filtering, reducing high order harmonic distortion and, in turn, jitter. Even the USB input stage benefits from dedicated regulation and multi-stage filtering, and the microprocessor control circuitry (often a local source of digital noise) has separate regulation, too. Hooking up with the Devil… At the front of the unit, alongside a standard 6.3mm single-ended headphone socket, resides a 4.4mm Pentaconn output for headphones offering balanced connection. At the back are two digital audio inputs: USB-A and a S/PDIF socket that accepts both electrical and optical signals, the former via a 3.5mm connector and the latter via a supplied adapter. The USB-A input features a ‘male’ connector, rather than a typical ‘female’ port for greater mechanical integrity.  A separate USB-C charging port is also provided, along with a 4.4mm Pentaconn balanced output to connect to an external amp. Accessories galore As befits a reference-level product, we’ve included a whole host of accessories in a luxurious travel case, the iTraveller. As the iDSD Diablo may be powered from the mains, as well as by its built-in battery, we’ve included our super silent, noise-cancelling iPower 5V AC/DC adapter to ensure optimal sound quality. Also included is a 4.4mm Pentaconn to XLR balanced interconnect cable to connect the iDSD Diablo to an amp and speakers (or a pair of active speakers) with balanced XLR inputs. Other supplied connectors include a high-quality USB-A audio cable, a USB-A to USB-C charging cable and an adapter to connect headphones with a 3.5mm jack to the 6.3mm single-ended output.

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. AudioQuest believes that today's digital devices should evolve as technology itself evolves, thereby delivering musical pleasure for many years to come. Our Desktop Device Manager will also allow you to identify your DragonFly's serial number and software version to ensure that the device is up to date. BEAUTIFUL SOUND IN A SMALLER PACKAGE... AND NOW WITH A TAIL All this goodness is packed into a sleek new case that measures just 2.26" x 0.73" x 0.47" (57.5mm x 18.6mm x 11.9mm), making the latest DragonFly 10% smaller and even a bit more pocket-friendly. Finally, to easily accommodate the increasing number of electronic devices that feature USB-C ports, DragonFly Cobalt comes with AudioQuest's USB-A to USB-C adaptor. THE REST OF THE DRAGONFLY FLEET: DRAGONFLYS BLACK AND RED While the original DragonFly created a new category of portable DAC, its USB power draw made it compatible with computers only.
