Know before you buy
The Diablo-X is the first portable DAC/amp designed to support xMEMS solid-state speaker technology. This allows it to drive next-generation xMEMS drivers with ultra-fast mechanical response and flat phase, alongside its high-performance capabilities for traditional headphones.
Yes, it functions as a high-fidelity DAC/amp for traditional gear as well. It features three power modes—xMEMS, Turbo, and Normal—to ensure you can properly drive everything from sensitive IEMs to demanding high-impedance headphones.
It is highly capable, supporting bit-perfect playback for PCM up to 768kHz and DSD up to 512. It also includes full MQA decoding, making it a versatile choice for high-resolution streaming services.
The balanced, differential circuit design, combined with iFi's PureWave and OptimaLoop technologies, significantly reduces noise and crosstalk. This results in a cleaner, more precise soundstage with an unadulterated signal path.
The device uses a 4800mAh battery, with power consumption varying significantly based on the mode used: 5W in Normal, 8W in xMEMS, and 12W in Turbo. It charges via a USB-C port that is compliant with the BC V1.2 standard for up to 1000mA charging current.
While it is designed as a portable unit, its robust output power and high-end DAC architecture make it an excellent desktop solution. You can connect it to your computer via USB or use the S-PDIF input for other digital sources.
