After a life spent designing developing and building truly special and legendary British audio electronics, Terry Clarke the creator, founder, and the very soul of our company asked the head of R&D Alex Cooper to build something extra special.

He asked him to direct us to create something to give back, something to take his sound to the home, a showpiece for the world, a sonic delicacy!


We´ve pioneered live and studio sound quality since the early 90s. It´s time to bring that audio expertise to the home audio roducts allow you to hear the sound as the artist intended; naturally, neutrally and accurately.
