Thanks all. Cambridge Audio duly purchased from Richer Sounds in Maidstone. Had a quick listen but had forgotten to take own CD. Bloke in shop asks what I listen to. After much horsetrading over this basic question (and no, they didn't have any stripped-down Italian speedcore) we settle on a classical CD. "What track?" "Oh, Chopin will do" says I. "Right you are, track 4".
It is only once it blasts out the shop that I realise I should have kept the glasses on to read the CD case: it is funny how you can empty a HiFi shop on a Saturday morning with a good dose of "la marche funèbre"...
