At this time Armstrong was responsible for 80% of the locally recorded hit records for major labels including EMI, RCA, Mushroom and Fable. In 1974 the studios were sold to the Age Newspaper Group and the name of the company was changed to Armstrong Audio Video (AAV). The studio's success continued into the 1980s. Young engineer Doug Brady joined the staff and started his career at AAV by recording and mixing Australia's highest selling record of all time: John Farnham's "Whispering Jack", going on to win ARIA Engineer of the Year three times. James "JIMBO" Barton was also added to the roster. He went on to work with Julian Menndelson & Trevor Horn, multi-platinum Queensrÿche and won a Grammy Award for Best Live Recording for Eric Clapton's "Unplugged". Other renowned acts who recorded at AAV in this period include U2, Paul McCartney, Madonna, Bob Dylan, Split Enz, Crowded House and Australian Crawl. In the 1990s the audio operations of AAV were acquired by a staff consortium headed by producer-engineer Ern Rose and the company's name was changed to Metropolis Audio. A controlling share was later acquired by another audio-visual company, Celtex, but this company eventually got into financial difficulties and Metropolis was abruptly closed down by the building's owners in 2006. In the meantime Edensound Mastering had taken residence in the famed 180 Bank Street building and directors Martin Pullan and David Drew took the opportunity to take over the lease and return the studio to its original Armstrong name. Doug Brady returned as a partner in the business having recorded numerous giant albums and recording projects as a freelance including the music for the Sydney Olympic Games in 2000. After a massive revamp including the installation of a vintage Neve console, Armstrong Studios today continues to be one of the foremost recording facilities in the southern hemisphere.
