iFi Audio Micro iDSD Diablo – High-Performance Portable DAC & Headphone Amplifier

iFi Audio Micro iDSD Diablo

The iFi iDSD Diablo is a reference-grade portable USB DAC and headphone amplifier built for purists who want raw, uncolored sonic performance. Designed with a fully balanced, differential dual-mono signal path (iFi PureWave) and precision clocking (GMT femto) to tackle jitter at the source, Diablo focuses on one thing: delivering exceptionally clean, powerful drive with outstanding detail retrieval. Dual Burr-Brown DAC chips and a high-performance XMOS digital engine enable “bit-perfect” playback across high-resolution PCM, DSD, DXD, and full MQA decoding, while the analog volume control keeps listening smooth and precise. With selectable Eco / Normal / Turbo power modes and serious output on tap, iDSD Diablo can confidently power everything from ultra-sensitive IEMs to demanding full-size headphones—at home or on the move.

What It's Good At:

• Driving virtually any headphone with high-voltage, high-current output and three selectable power modes (Eco/Normal/Turbo).
• Purist, uncolored playback—no Bluetooth or DSP-style sound shaping to distract from “straight-wire” performance.
• Ultra-low distortion, high resolution thanks to fully balanced PureWave circuitry and precision regulation across critical stages.
• High-res format flexibility with PCM up to 768kHz, DSD up to DSD512, DXD, and full MQA decoding support.
• Quiet, stable performance with upgraded jitter control (GMT femto clock + buffering) and low-noise power design.
• Travel-ready complete kit including iPower 5V supply, iTraveller case, balanced XLR cable, and essential adapters/cables.
