THX and Massdrop Partner to Launch World’s Most Linear Amplifier with THX AAA™ Technology

San Francisco, CA (January 9, 2018) – THX Ltd., renowned for the certification of world-class cinemas and consumer electronics, and Massdrop, today announced the Massdrop-Made 789 Desktop Headphone Amplifier featuring THX Achromatic Audio Amplifier (THX AAA™) technology.

The THX Achromatic Audio Amplifier (THX AAA) delivers the ultimate no-compromise audio experience by delivering the world’s highest fidelity audio signal, achieving higher peak output power, and maximizing battery life.

THX AAA reduces harmonic, intermodulation, and crossover distortion by 20-40 dB to guarantee a realistic and fatigue-free listening experience. It accomplishes this using a patented feed-forward topology to null conventional distortion and noise mechanisms, resulting in the world’s most linear amplifier. 
THX AAA enables maximum output power and sound pressure level (SPL) for greater dynamic range. In addition, THX AAA has highly efficient power management delivering significantly longer battery life. THX AAA technology is a flexible solution that can be easily scaled into any amplifier design for mobile or desktop, according to its fidelity, output power, and price point. The Massdrop products are excellent examples.

“When Massdrop approached us with a request to deliver a more powerful version of our THX AAA amplifier, we developed THX AAA-789, an exclusive high-current version with bridged output stage to meet the needs of this unique product,” said Russ Schafer, GM and SVP of Technology, THX Ltd. “We’re excited to partner with Massdrop to deliver an unparalleled audio experience to consumers with the launch of their latest product featuring THX AAA technology.”

The Massdrop Desktop Headphone Amplifier utilizes a bridged THX AAA-789 amplifier design for incredible output power (2 x 6000mW, 16 Ω) and low noise (136 dB SNR) with the world’s lowest distortion (-140 dB THD @ 300Ω, 2V). These no-compromise performance figures make the THX AAA-789 amplifier design capable of driving any headphones – including high impedance, high current, and high sensitivity types.

“THX and Massdrop are an ideal pairing: a classic brand with renowned technology and a community-first platform bringing that technology to market at an accessible price point,” said Will Bright, Head of Custom Products, Massdrop. “We couldn’t be more excited to announce this collaboration at CES and we can’t wait to ship these out for community feedback.”
