While Adam Worsfold and Anthony Brady were serving as apprentice electronic design engineers they redeveloped an early design from the archives of an underground vault at Thorn EMI.
The guys knew music could be sound better than it did amongst the sea of amps out there , so Anthony Brady and Adam Worsfold designed a new amp that was built the way it should be and sounded better than the rest. They created the legacy of ONIX AUDIO with the legendary ONIX OA21
They integrated components they sourced that had musicality being the founding principle of parts they used . Once a design was perfected to their ideals they appointed a single sales outlet. Brighton HiFi was a shop in the UK seaside town of Brighton and Craig Hill ( The salesman ) ran the shop with his father . It helped build ONIX AUDIO
IN 1984 ONIX AUDIO was born and history was made. They were disrupters of the 80s within the Hifi world . Ahead of the game in so many ways .
The first real product ONIX AUDIO Made is the now 40 years later the classic and iconic OA21 . It was unique starting the shoe box size amps , and it took the Hifi world by storm. The ONIX OA21 being the first all black 3 knob half size amp.
Many companies have since copied our original format throughout the years. It was the first shoebox size minimalist amplifier . It is known to be an ageless design , with pure black cosmetics and the iconic 2 huge knobs on the front with the third smaller knob in the middle . The ONIX DNA family theme is still carried on today in what we do and design at OA21
