Editor's Note: We are reprinting this 38 year-old "As We See It" essay because if you substitute the words "WiFi" and "cellphone" for "Citizen's Band" and "CB Radio," you will realize that not much has changed in the decades since, with our audio systems still awash in a bath of RFI.—John Atkinson

Although Citizen's Band radio may hold little interest for perfectionist audiophiles, there is a good chance that it may intrude upon our activities in some disastrous ways if we, and the audio industry in general, sit back and ignore what has been going on behind the scenes in Washington, DC.

It was with regret that I heard John Ulrick had passed away on May 20, 2015 due to complications from cancer. With Arnie Nudell and Cary Christie, John was one of the founders of loudspeaker manufacturer Infinity, a company that, with Audio Research, Magnepan, Mark Levinson, and Threshold, epitomized the nascent High End that emerged in the early 1970s. After leaving Infinity, John Ulrick started Spectron, to manufacture class-D amplifiers.

Just by chance, I met with the John Ulrick, in Los Angeles in late 1987, when he was doing some design consultancy on a switch-mode power amplifier to be used with the Sumo Samson subwoofer. As I had my Walkman Pro with me, I took the opportunity to tape some background from John about the birth of Infinity and about switching/pulse-width-modulated/class-D amplifiers—boy, can this man talk about switching amplifiers! The natural kickoff question was, How did Infinity get going?

Earlier this year I pried myself from my upstate-New York home long enough to visit Robert Lighton Audio: a beautifully decorated suite on the 12th floor of 37 West 20th Street in Manhattan's Chelsea district, in which an Audio Note Ongaku amplifier shares space with a Suzanne Guiguichon armoire, and from which the view of the Empire State Building is stunning.
