I worked at a big Japanese retail store that had a large audio/video department from '84-'87, when I was nineteen. I also worked, concurrently, at a high-end audio store from about '85-'87. Back then some of the big names were Threshold, Counterpoint, Spectral, SOTA, Linn and Infinity.
The owner of the high-end store was from the far east and was a classical music lover. He happened to own the building it was in and decided to convert it to a radio broadcasting station with a small music hall for the preservation of a classical music. Twelve years later I revisited the building when an opera singing friend had a performance there. I suppose the music never left the building.
