Simple and classic designed amplifier, grown up son of the classic OA21s defining our brand ONIX

( 1990 Review of OA21s HERE)

Appreciated throughout time and always part of the family. Many electronic designs has changed over and over but the OA21 is timeless. It was perfect from day one . Like a well known watch or a world renowned car, pure and perfect by simplicity its great build will last the life of the music you enjoy .
