iFi Audio iDSD Diablo 2

iFi Audio iDSD Diablo 2 DAC and Headphone Amplifier

The iFi Audio iDSD Diablo 2 is a portable DAC/amp designed for audiophiles seeking pure, unaltered sonic performance. It features an elegant design with 22 grooves that aid in heat dissipation. This device is crafted for true audio enthusiasts, offering a range of features that enhance the quality of your audio and deliver a rich, immersive listening experience.

The Diablo 2 Redefines Power in a Portable Format

With an increased headphone output power of 5,180 mW, the Diablo 2 stands at the pinnacle of compact headphone amplifiers. Its balanced dual-mono circuitry delivers exceptional audio performance, whether you’re at home or on the go. For audiophiles juggling between different setups, the Diablo 2 becomes a valuable ally, offering the best of both worlds.

Bluetooth 5.4 and aptX Lossless

The Diablo 2 is the world’s first portable DAC/amp to incorporate Bluetooth 5.4, with support for the aptX Lossless codec. This technology enables lossless CD-quality streaming, providing a wireless experience that doesn’t compromise audio quality. Whether you’re commuting or at home, the Diablo 2 ensures advanced connectivity and unmatched sonic fidelity.

xMEMS: A Revolutionary Technology

The Diablo 2’s predecessor introduced xMEMS semiconductor micro-speaker technology, and the Diablo 2 takes it even further. With an ultra-fast mechanical response of 15 µs, a silicon diaphragm 95 times more rigid than plastic, and a flat phase response of 2°, the benefits are manifold. Music enthusiasts will enjoy enhanced spatial sound precision and clearer mid-high frequencies.

Power Modes and iEMatch: Optimal Customization for All Headphones

The Diablo 2 offers unparalleled flexibility with three power modes: Normal, Turbo, and Nitro. Whether you’re using IEMs, medium-sensitivity headphones, or demanding headphones, the Diablo 2 adapts to your needs. The integration of iEMatch technology eliminates background noise, delivering an exceptional listening experience for high-sensitivity headphones and earphones.
