From a purely technical point of view, CD reproduction has the edge, most modern recordings utilise computer technology which carries through to the CD reproduction, with negligable loss of sound quality. Vinyl albums were usually made from analogue tape, and did loose some of the higher frequencies in the pressing stages. In terms of longevity and storage, CD's have the edge again - their compact size and durability ensures a longer life than vinyl which wears with age, no matter how carefully it is cared for. Purists insist that vinyl has a 'warmer' sound than CD, although the vast majority of listeners are either unable to detect the difference, or don't especially care to listen for it. The world takeover of CD's as the format of choice, and the sidelining of vinyl to dance tracks and die-hard enthusiasts demonstrates most people's preference.
