I want to know the answer to the following question:
What magazines provided reviews for audio equipment?
All the background I'm provided with is that "After 1949 a variety of improvements in recording and playback technologies, especially stereo recordings, which became widely available in 1958, gave a boost to the "hi-fi" classification of products, leading to sales of individual components for the home such as amplifiers, loudspeakers, phonographs, and tape players.". Is that enough to answer the question?
