Hi Fi News

A beyond-cool look at the world of high-end audio design for passionate collectors, obsessive audiophiles, and design fans At a time when sales of vinyl records have hit a 25-year high, and analog technologies are providing the kind of extraordinary audio experiences that our increasingly digital world has started to remove, Hi-Fi is essential reading. This unique book explores just how, when, and why the world fell in love with the look, feel, and sound of top-of-the-line audio equipment. Hi-Fi traces this fascinating evolution from the 1950s to today (and tomorrow), taking readers right up to the current renaissance of all things analog and the emergence of cutting-edge designs for die-hard audiophiles.
