This classy HiFi equipment that I encountered yesterday on the street made me think about the importance, at a certain point in time, of revealing certain technical characteristic. The presence of the graphic equalizer displayed on the device definitely gives some cachet and might have created some interesting conversations by users.

Revealing this sort of information is also intriguing as most users (in general perhaps not the target group of that device in its time) are not always versed in the art of tuning equalization. Perhaps the aesthetical effect is more fascinating; I remember a friend who use to like the representation of equalizer on his device as it looked "futuristic": are mathematical visualization still classy now?
