iDSD Diablo-X: Simply eXceptional

At the heart of iFi iDSD Diablo-X beats the specially selected Burr Brown® True Native chipset in a dual-core configuration, treating you to the ultra-high-resolution that is 2nd to none. The iDSD Diablo-X uses cutting-edge tech to work with MEMS headphones. The bias, equalization, and amplification have all been specifically crafted to bring out their best.

This aggressively curvaceous headphone amp spiced up with deep bass and fully balanced circuitry will take you for a ride through the world of ultimate performance you'll never forget. The pure performance iDSD Diablo-X, designed for true audiophiles, aims to keep sound as close to its natural form as possible.

Packed under the hood of this all-new model is turbocharged Bit-Perfect octa-speed DSD512 and double-speed DXD (705.6/768kHz), making iDSD Diablo-X's super-speed not mere hyperbole.

Thanks to iFi-designed, cutting-edge technological innovations such as Direct-Drive® and Headamp Turbo®, devilishly powerful iDSD Diablo-X drives ultra-sensitive IEMs just as well as the most demanding over-ears with an unswerving authority.

Matching Bi-polar transistors welcome you to the addictive symphony of natural sound with incredibly low distortion (THD+N = 0.00002%.) Equipped with iFi custom ultra-low noise Op-amps, iDSD Diablo-X will take your music to the sonic stratosphere.

xMEMS eXplained

The xMEMS microspeaker technology uses the 'piezoelectonic' effect to create a paper-thin solid-state speaker. These micro-speakers offer great potential to push the boundaries of IEM and headphone performance.

As xMEMS themselves say, “The inverse piezoelectric effect is created by applying electrical voltage to make the piezoMEMS contract or expand, converting electrical energy to mechanical energy which excites an integrated silicon membrane to move air and generate acoustic sound waves… xMEMS’ piezoMEMs actuators offer an increased range of movement enabling rich, loud audio."

Unadulterated Performance

The Diablo-X focuses on pure performance with much attention given to the power supply circuity.

Battery power provides ultra-clean and stable DC current avoiding house power issues of dips, spikes and noise-inducing RFI/EMI. BUT there are sonic downsides resulting from low output voltage and inconsistent output impedance as batteries discharge.

In order to make less efficient headphones like planar magnetics sing, the voltage needs to be stepped up from 3.7V to +/- 15V. A step-up converter running at 1.2MHz is used (a frequency far beyond audibility that is easier to filter than a typical supply), enabling high linearity and ultra-low noise.

Clean, Pure, and Powerful

This unit outputs such clean and pure sound. And the unit has massive amounts of power. This is the nicest transportable DAC/Amp I've owned. My set up is 2021 MacBook Pro streaming Tidal, headphones Focal Stellia. Highly recommended!
