THE VERDICT

THX’s portable DAC/amp delivers dynamic and spatially precise sound. Paired with the right headphones, it’s a compelling option for portable high-res playback

Home theater enthusiasts know THX for its certification program, an initiative responsible for the familiar logo emblazoned on all manner of gear for nearly three decades, along with the Deep Note trailer heard in certified movie theaters and on home video releases. Surprisingly, the company never released its own “THX” product, a situation that now changes with the arrival of the THX Onyx portable DAC/headphone amplifier.
