When the OA21s amplifier was created by us 40 years ago , we simply did not know it would become an ONIX legacy.

We didnt know that a simple and ageless design with three knobs , would be cherished by hundreds of thousands.


Then OA21 matured and became a part of many families and their memories


Like a well known watch, or a world renowned car, both beginning with the letter " R " , we use the same suppliers

When you appreciate what you are buying, we know our job is done, and your memories start .
