I hope that members outside the UK can view these http://www.bbc.co.uk/music/articles/9dd5bda0-f21f-44e6-8bce-df281b97b6bb Unless you are into music synthesizers I would recommend skipping straight to No.4 in which they analyse why the newly launched Sony Walkman sounds so good, both with a spectrum analyser and a demonstration of the magnets used in the headphones. No.5 seems to indicate that personal Stereos were as common as Smartphones are today. At least the people using them can see where they are going. I wonder what happened to the MiniDisc vending machine in No.9? £2 a track sounds excessive but was probably comparable to a CD single and you did get the lyrics as well !
