Since 1979 Technical Brain has been dedicated to research and development of audio equipments as well as high quality audio repair and maintenance services.

With our expertise in audio gained from many years of experience, we launched our innovative audio system TB-Zero series in 2005 and have won great critical acclaim in Japan and beyond.

TB-Zero series is designed to be thoroughly faithful to sources.
Our ultimate goal is to recreate a sense of occasion in real music making.

 
Technical Brain launched a family of emitter resistance-less amplifiers in 2002.
(JP Patent No. 4284102)

In order to achieve true linearity and high-speed response, we made emitter resistance-less circuits which had zero-ohm emitter resistors and eliminated all contacts starting with the relays of the protection circuit, both of which affected sound quality a lot.
In addition, we derived power cables directly from a large size Flat Wire power transformer with large EI-core (20kg).
These innovative technologies affecting the sound quality attracted attention and attained a reputation as amplifiers of good sound quality.
Recently, several manufacturers have launched some amplifiers imitating our concept.
This must be the proof that our creative challenges have been appreciated.
It is our great delight that many people share and use our patented technology and ideas to improve their sound quality.
I would like to express my sincere gratitude for a lot of music lovers who bought our products after listening and audio specialized magazines which awarded a number of prizes to Technical Brain since the amplifier's launch in 2002, despite Technical Brain was an unknown amplifier maker.
Technical Brain will continue to make new evolution for further innovation. I hope you will look forward to this.

Naoto Kurosawa, Technical Brain Ltd.
