The Devil in the Detail
Pure Sonic Performance
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 here.
And with MQA now available over S/PDIF, you can take advantage of any MQA CDs in your collection.
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
Power that does not corrupt.
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.
Crucial components for maxed out performance, more below.
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.
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 twin XLR balanced interconnect cable to connect the iDSD Diablo to an amp and speakers (or a pair of active speakers) with balanced XLR inputs.
We’ve also added a short (15cm) USB-C to USB-A audio cable, as well as an extension cable plus a USB-C charging cable and an adapter to connect headphones with a 3.5mm jack to the 6.3mm single-ended output.

- shipping fees will vary depending on international carrier(s)3, and will be displayed during checkout.
- do be aware of additional import tax/VAT that may apply.
Due to recent changes in U.S. trade regulations, additional tariffs are being imposed on products manufactured in China and imported into the United States. As many of our audio products are made in China, orders shipped to U.S. addresses may be subject to an added tariff charge at checkout, reflected as a "U.S. Import Tariff Surcharge". Please note that this surcharge amount is determined by U.S. import policies and may vary significantly depending on product categories and any future policy adjustments. These charges are necessary to ensure compliance with U.S. customs requirements and to allow us to continue serving our U.S. customers reliably.
