About the iFi Audio iDSD Diablo

Jeff Miller

Clear sound and pristine power in a travel-friendly design

Maximum sonic performance. That's what informed every design choice for the battery-powered iFi Audio iDSD Diablo DAC/headphone amp combo. The beauty is in its simplicity. Sure, there's a lot of cutting-edge tech and high-grade circuitry under the hood. But it doesn't feature all the extra DSP modes and tweaky controls found in other iFi gear — like the micro iDSD Signature. Instead, this piece is designed to preserve audio purity.

Product Research


Overview: The iFi-Audio iDSD Diablo is a bright red transportable DAC (digital-to-analog converter) and headphone amplifier with USB and S/PIDF digital inputs, balanced and unbalanced headphone outputs, and a balanced line output. You can use it with your smartphone or tablet, your home or office computer, or a home disc player with a digital output. The iDSD Diablo and all its accessories can be stored in the iTraveller travel case. It measures 2-3/4" x 1" x 6-5/8", and weighs just over 11-1/2 ounces.

Digital-to-Analog Conversion: The iDSD Diablo plays Hi-Res audio in the native format, including DSD (up to 512 MHz), DXD (up to 768 kHz), and PCM (up to 768 kHz). It also fully decodes MQA (Master Quality Authenticated) tracks up to 384kHz, performing the full three unfold decoding process. It uses dual Burr-Brown True Native® DAC chips and the XMOS 16-core processing chip. With iFi-Audio's GMT (Global Master Timing) femto-precision clock and intelligent memory buffer, digital jitter is virtually eliminated. The iDSD Diablo transportable DAC supports the following audio formats:

  • DSD: 512, 256, 128, 64 MHz (Octa-/ Quad-/ Double-/ Single-Speed DSD)
  • DXD: 768, 705.6, 384, 352.8 kHz (Double / Single-Speed DXD)
  • PCM: 768, 705.6, 384, 352.8, 192, 176.4, 96, 88.2, 48, 44.1 kHz
  • MQA decoder

PureWave: iDSD Diablo utilizes a new, balanced, symmetrical dual-mono design called PureWave, which fully separates the left and right channels to reduce noise and crosstalk. PureWave uses short, direct signal paths, providing a pure sonic performance.

LED Indicator: The iDSD Diablo has an LED beside the volume control that indicates the sampling frequency received from the source. The LED color scheme is as follows:

  • Yellow: PCM 44.1, 48 kHz
  • White: PCM 88.2, 96, 176.4, 192, 352.8, 384, 705.6, 768 kHz
  • Cyan: DSD 64, DSD 128
  • Red: DSD 256, DSD 512
  • Green: MQA
  • Blue: MQA Studio
  • Magenta: Original Sample Rate (MQB)

Headphone Amplifier: The iFi-Audio iDSD Diablo has a powerful headphone amplifier that can drive most headphones and in-ear monitors. There are two headphone outputs: a 4.4mm Pentaconn balanced output, and a 6.3mm (1/4") single-ended output. A 3.5mm-to-6.3mm adapter is provided for your 3.5mm-equipped headphones and IEMs. The iDSD Diablo can provide up to 166 times more output power, compared to a typical laptop headphone output (4980mW vs 30mW). Using the front panel switch, you can choosing one of three settings to get the right amount of output for your headphones or IEM:

  • Eco: lower output for high-sensitivity IEMs
  • Normal: for medium-sensitivity headphones
  • Turbo: highest output to drive the most demanding headphones

Combo S/PDIF Input: The iDSD Diablo has a combination S/PDIF input that accepts both electrical (coaxial) and optical signals, via the 3.5mm connector (Toslink mini plug adapter supplied).

Note: The S/PDIF port supports PCM signals only up to 192kHz.

USB Input: The iDSD Diablo has a male Type-A USB 3.0 input that can be used with your smartphone, tablet, or home/office computer. The male connector is used rather than a typical female USB port because of greater mechanical integrity. A 39" USB 3.0 male-to-female Type-A cable is provided for connecting the iDSD Diablo to your laptop. You will need an Apple CCK cable for connecting your iPhone, or an "OTG" cable for your Android device, if desired.

Balanced Output: The device is equipped with a 4.4mm (Pentaconn) balanced line output on the rear panel. This allows you to use the iDSD Diablo as a balanced DAC for connecting to active speakers or a stereo amplifier. Included with the device is a 4.4mm-to-dual XLR adapter to make it easier to connect with an amp or powered speakers.

USB-C Power Port: The rear panel has a USB-C (5V) power port for charging the device's internal battery. A full recharge with a standard charger (5V 1A) takes approximately 12 hours to complete. With a high-powered charger (5V 2.5A), such as the supplied iPower AC adapter, the recharge would take approximately 6 hours. An LED indicator beside the charging port displays the battery status:

  • White: >75%
  • Green: >25%
  • Red: >10%
  • Red (flashing): <=10%

Battery Power: The iDSD Diablo is powered by a built-in 4800mAh Lithium-polymer battery. When fully charged, the battery life is dependent upon the selected power mode. In the Eco Mode, you can expect approximately 12 hours of battery life. In Normal Mode, approximately 9 hours is expected. In Turbo Mode, battery life is expected to be approximately 6 hours.

iPower AC Adapter: Bundled with the iDSD Diablo is the iFi-Audio iPower ultra-low noise power supply. You'll need the supplied adapter (USB-C to DC barrel connector) to connect the power supply to the DAC. iPower can be used to charge the built-in battery, or to power the device with household current. iFi-Audio recommends using battery power to assure that you get ultra-clean and stable DC current.
