Reference THX Analog Headphone Amplifier

Mytek Audio just announced their new Liberty THX AAA™ HPA , an analog headphone amplifier featuring THX Achromatic Audio Amplifier (THX AAA™) , which is said to be the most linear amplifier technology available today. The company says the Liberty THX AAA™ HPA, “provides astonishing musical accuracy, unprecedented dynamic range, as well as infinitesimally low levels of noise and distortion.” Further adding, “Liberty THX AAA™ HPA is a reference grade device for both the musically passionate headphone enthusiast, and for sound engineers in professional audio environments.”

Mytec boasts the Liberty THX AAA™ HPA allows the user to hear music with maximum transparency and detail and with minimum impact of the amplifier on the original sound. This is achieved using THX’s patented feed-forward error correction circuit topology which allows the THX AAA™ based amplifier to reach its maximum output power rating (1 ampere and voltages reaching 25Vp-p) while exponentially reducing noise and distortion levels. Unlike the competition where increased output power is typically accompanied by proportional amounts of noise and distortion, the Liberty THX AAA™ HPA encounters a reduction in distortion by up to 40dB.

Liberty THX AAA™ HPA uses the highest quality gold plated connectors and a selection of the highest grade parts, including an oversized 60-watt toroid power transformer, separate low noise power regulators for left and right channels, and a large bank of low impedance power supply electrolytic capacitors. Multiple protection circuits are in place to ensure that the output relays are disabled during ‘power up’ until all power supplies reach full voltage and proper stability, and during faulty conditions like overloads and short circuits.

As a result, Mytec says Liberty THX AAA™ HPA can drive any pair of headphones available today.

About Mytek Audio

Mytek was founded in New York City by Michal Jurewicz in 1992. He began working at Manhattan’s famed Hit Factory recording studio in 1989 with the likes of Paul Simon, Billy Joel and Barbara Streisand, recording to analog tape. Here he learned the “ins and outs” of what a great recording was supposed to sound like and which equipment was necessary to achieve this. Famously, he repaired a room full of broken equalizers, amplifiers and compressors that were just too complex for the other technicians to handle. It was this reputation that landed him a job as Skyline Studios’ tech engineer. Skyline was the home of legendary music producer Nile Rogers and the preferred studio for the likes of Mariah Carey and James Taylor.  

While at Skyline, Michal developed solutions to help improve the workflow and sound quality of the new digital systems. It was here that Mytek  was born 1992. From the very beginning, artist and producers praised the sound quality of Mytek’s  equipment. Soon almost every NYC recording studio had a “Mytek  Private Q” headphone monitoring system and those using Mytek’s  first analog-to-digital converters produced recordings that didn’t suffer from the harsh sound that was so typical of the digital recordings from the 1990’s.

Since then Mytek has continuously innovated; From pioneering 18, 20, 24 and now 32-bit PCM recording to being part of the “DSD Super Audio CD Project” and today helping to develop MQA mastering and playback. Most recently, as digital audio and internet distribution began to evolve together, the barrier of audio quality between the professional studio and the home has vanished. It was with this eye towards the future that Mytek began designing playback equipment for music lovers, not just music makers. Today the same equipment used to create timeless music is accessible for a lifelong enjoyment of music. Michal Jurewicz has consistently demonstrated that a proper understanding of how to digitally encode music in the recording studio results in a cutting edge ability to design the award winning DACs used today by Mytek for digital music playback. Convenience, design and sound quality are all at the heart of everything Mytek  does.  

Mytek  currently maintains two physical locations for Sales, R&D, Support and Distribution: Mytek Audio Headquarters in Brooklyn , New York and Mytek Europe  Corporation, the EU Branch in Warsaw, Poland.
