By Ken Kessler and Dr. Andrew Watson. GP Acoustics International Limited, 2011. $89.99. Hardcover, 12" by 12" by 0.9", 216 pp. ISBN 978-988-15427-4-8. Available from selected KEF dealers and Amazon.com.

Ken Kessler's latest "coffee-tabler" (my favorite publishing-industry insider neologism) celebrates the 50th anniversary of the founding of KEF Electronics by documenting the history of the venerable loudspeaker manufacturer. While the book doesn't quite start with a bang, it does start with an evocative vignette. The year was 1979, the place the ballroom of Buckingham Palace. Her Majesty the Queen, about to present KEF's founder, Raymond Cooke, with the medal representing his having been made an Officer of the Most Excellent Order of the British Empire (OBE), inquired, perhaps formulaically, "This is for loudspeakers?"

From the Mouth of the Sun's "Sitting In a Roofless Room," from the new album Woven Tide, released by Experimedia.

Back in the late 1980s, it seemed a good idea: Separate a CD player's transport section from its D/A circuitry so that each could be optimally designed, and, as D/A technology improved, the sound of your CD player could be upgraded by replacing the outboard D/A processor. The catch was that the transport and D/A chassis needed to be connected with a serial data link: S/PDIF in optical or electrical flavors, or balanced AES/EBU. To minimize the number of cables required, the format of that link embedded the clock data within the audio data, which rendered the link sensitive to interface timing uncertainty, or jitter.
