Stereo was started in 1973 and is the oldest German hi-fi magazine on the market. Stereo has always focused on the pure audiophile perspective of listening to music, even when surround-sound and home cinema appeared. Today, Stereo is one of the three big hi-fi magazines in the German market. Stereo offers tests and other information such as, news, interviews and CD reviews. Although most of its work is devoted to high-end products, it also includes MP3-players and mini systems.
