"I've got a great idea, RL," said John Atkinson to me one fine fall morning five years ago, as we relaxed over cappuccino and croissants in the slowly rotating editorial suite of the imposing Stereophile Tower that---surmounted by a heroic statue of J. Gordon Holt, thumb down, lip curled, great bronze cigarette glowing triode-red---rises like a Tube Trap of the Gods to dominate the downtown skyline of our round brown town of La Villa Real de la Santa Fe de San Francisco de Asis. In a paroxysm of the editorial euphoria that comes upon him when he suddenly envisions page after page of Stereophile copy which he himself does not have to write, JA then outlined for me the annual list of the Greatest Performances recorded in the Greatest Stereo Sound that has since become the "Records To Die For" we all love and hate---one of Stereophile's most entertaining, annoying, and downright fun features.

"My car is supercharged, not turbocharged, so you see there's no throttle lag," explained Yves-Bernard André as he reversed at what seemed like 80mph up a narrow cobbled Paris street. "D'accord," I mumbled, afraid to loosen the white-knuckled grip I had on the passenger grab handles. Yves-Bernard's car may have been pointing the right way down the one-way street, but it was not actually traveling in that direction. Okay, so it was 2am and the good residents of the Dix-septième Arrondissement were busy stacking Zs (en français, "emplier les ronflements"). But I still didn't think we would've been able to explain the logic of the situation to the gendarmes (les flics, en français).

Lee de Forest filed for a US patent on his "Audion"—the first triode—on October 25, 1906, but never could explain why it worked (footnote 1). It was up to Armstrong and Langmuir, in their pioneering work, to place the hard-vacuum triode on firm scientific ground. When the US entered World War I in April 1917, the Army had to rely on French tubes. Six months later, Western Electric was mass-producing the VT-1 receiving tube and the VT-2 transmitting tube. However, it was only in the decade following World War I, as designers became conversant with the triode amplifier, that many of the crucial elements of tube amplification were nailed down. Technical issues such as coupling two gain stages and selection of optimal coupling impedance were already resolved by the mid-1920s. The triode ruled supreme until the tetrode came along in 1926, followed in 1929 by the pentode from Philips's research laboratories in Holland.

Anyone who's ever looked for it knows how rare audio-friendly living space is. Perhaps someday an enterprising developer will build Audiophile Acres---a whole subdivision of audio houses or soundproofed condos that'll meet these needs---then stand by while hordes of long-suffering audiophiles stampede the sales office, frantically waving down-payments in their sweaty hands.
