Diablo’s Energy Sources

The 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.

Devil in the details.

When examining the Diablo 2’s front panel, you’ll find a new Volume Lock switch next to the volume control, preventing accidental adjustments during transport.

At the back panel’s left side, there’s a switch for mode selection and Bluetooth pairing. On the right side, two USB-C ports streamline cable management—one for audio and the other for charging.

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. In comparison, aptX Adaptive has a maximum bitrate of 420kbps, while LDAC^TM offers a higher bitrate of 990kbps.

The Diablo 2 used Qualcomm’s new QCC518x Bluetooth audio chip, is qualified to Bluetooth 5.4, supported all* Bluetooth formats including: aptX Lossless, aptX Adaptive, aptX, LDAC^TM, LHDC/HWA, AAC and SBC.

*As of 10 Nov 2023. Check your device for Bluetooth codec support.

Dual Core Burr Brown chipset provides Bit-Perfect DSD and PCM support at sample rates up to 768kHz, DSD512, and Full MQA decoding. Even as Spotify is moving towards Lossless, don’t get left behind.

Diabolical Innovation. Shattering Boundaries.

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.
