Heavenly Sound. Devilish Power

The iFi iDSD Diablo 2, dressed in Devilish Red, succeeds the Diablo-X, boasting a slew of enhancements such as increased headphone output power, support for lossless Bluetooth codecs, xMEMS technology, iEMatch, a USB-C input, improved circuitry, and more.

As an audiophile, you likely use different systems for home and mobile setups. The Diablo 2 offers the best of both worlds with its powerful 5180mW output and balanced dual-mono circuitry, making it the most powerful headphone amplifier of its size.

Ruling All Bluetooth Codec and Formats

The Diablo 2 features the latest Bluetooth 5.4 technology, supporting the new aptX Lossless codec with a maximum bitrate of 1200kbps. In comparison, aptX Adaptive has a maximum bitrate of 420kbps, while LDAC offers a higher bitrate of 990kbps.

The Diablo 2 used Qualcomm’s new QCC518x Bluetooth audio chip, is qualified to Bluetooth 5.4, supports all (as of Nov. 2023) Bluetooth formats including: aptX Lossless, aptX Adaptive, aptX, LDAC, LHDC/HWA, AAC and SBC.

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

Diabolical xMEMS Innovation

The predecessor of Diablo 2 pioneered support for xMEMS solid-state micro-speaker technology, enhancing IEM and headphone performance with several unique benefits:

  • 15µsec mechanical response, 150x faster than typical drivers
  • 2° flat phase response for precise sound and precise +/- 1° phase matching for enhanced spatial sound accuracy
  • Speaker diaphragm made of silicon, 95x 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 tech into the Diablo 2. It utilizes the piezoelectric effect to create paper-thin solid-state speakers by converting electrical energy into mechanical, exciting a silicon membrane to generate powerful acoustic sound waves for enhanced output.

Wings of Inferno

The Diablo 2 comes with x4 wings that you can customize to position it horizontally like a desktop DAC/amp, or vertically to save space. Additionally, it features 22 rails for improved cooling performance, with 8 of these rails being compatible with the Diablo wings, enabling desktop stand use.

Lovely thing ;-)

Drives my DCA Stealth with complete ease. Bluetooth is very handy for watching movies.
As always, Bloom was stellar to deal with. My only source for high-end head-fi.
