iFi Audio iDSD Diablo 2 Portable DAC/AMP

The Diablo 2, draped in Devilish Red, takes the reins from the Diablo-X, showcasing a myriad of improvements, including enhanced headphone output power, support for lossless Bluetooth codecs, xMEMS technology, iEMatch, a USB-C input, upgraded circuitry, and more.

As an audiophile based in Denver, you're likely to appreciate the Diablo 2's versatility for both home and mobile setups. With a robust 5,180mW output and balanced dual-mono circuitry, this portable DAC/Amp stands out as the most potent headphone amplifier in its class.

Diabolical Innovation. Shattering Boundaries.

Setting a new standard, the Diablo 2 is the world's first portable DAC/Amp featuring Bluetooth 5.4, supporting aptX Lossless—the exclusive Bluetooth codec for lossless CD-quality streaming. Its predecessor pioneered xMEMS solid-state micro-speaker technology, offering a 15µsec mechanical response, flat phase response, and a silicon diaphragm for enhanced performance.

Partnering with xMEMS, iFi integrates this groundbreaking technology into the Diablo 2, utilizing the piezoelectric effect to create paper-thin solid-state speakers. Press the NOS button for a power boost, with three modes catering to various headphone sensitivities.

Ruling all Bluetooth codec and music formats.

The Diablo 2 boasts Bluetooth 5.4 technology, supporting aptX Lossless with a maximum bitrate of 1,200kbps. With Qualcomm's QCC518x Bluetooth audio chip, it covers all Bluetooth formats, including aptX Lossless, aptX Adaptive, aptX, LDAC, LHDC/HWA, AAC, and SBC.

Dual Core Burr Brown chipset ensures Bit-Perfect DSD and PCM support at high sample rates, future-proofing your audio experience.

Wings of Inferno. Devil in the details.

Customize the Diablo 2 with four wings for horizontal or vertical positioning. Enhanced cooling with twenty-two rails and a Volume Lock switch on the front panel prevent accidental adjustments. Mode selection, Bluetooth pairing, and dual USB-C ports at the back streamline functionality.

Sound So Moving. Even the Devil May Cry.

Featuring PureWave, Servoless DirectDrive, OptimaLoop, and Advanced Jitter Reduction Technology, the Diablo 2 delivers pure, detailed, and emotionally resonant sound, challenging desktop DAC/amps.

Diablo’s Energy Sources.

Power the Diablo 2 with battery or mains. Battery power ensures clean and stable DC current, while the iPower2 power supply with Active Noise Cancellation II cancels incoming EMI and RFI noise, making it more than 10 times quieter than typical audiophile power supplies.

In the realm of DAC/Amps, the iDSD Diablo 2 reigns supreme, ensuring your headphones should be scared.
