THX Achromatic Audio Amplifier

World’s Most Linear Amplifier Technology for Headphones and In-Vehicle Audio Systems

THX Achromatic Audio Amplifier (THX AAA™) ensures the ultimate no-compromise headphone audio experience by delivering the world’s highest fidelity audio with infinitesimally low levels of noise, distortion and power consumption.


Patented feed-forward error correction topology that nulls conventional distortion mechanisms

Reduction of harmonic, intermodulation, and crossover distortion by up to 40dB, resulting in a realistic and fatigue-free listening experience

Enables maximum output power for greater dynamic range and sound pressure level (SPL)

A convenient modular solution which includes power supply, and can operate from a single 3.6V battery

Minimal bias current and highly efficient power management to optimize and extend device battery life

Scalability that allows incorporation into any headphone or in-vehicle amplifier design, with the flexibility to match the required fidelity, output power, and price point
