There's no place for fashion in epidemiology, aeronautical engineering, or the mining and storage of uranium. Fortunately, domestic audio is less serious, its goals more scattered and ambiguous, than those and a thousand other pursuits.

And so, throughout the 20th century, any number of trends in domestic audio popped up their heads, some remembered as fads, others as legitimate approaches to playback. Among the latter are amplifiers whose output sections operate in single-ended mode, in which the entire signal waveform is amplified by a single device.

One summer in the mid-2000s I purchased a pair of Cambridge Audio components for my red-headed, tango-dancing Texas girlfriend. She quickly saw through my ruse to install some solid hi-fi in her New Jersey home away from home—but eventually she acquiesced, and soon Michael Martin Murphey (she), the Beatles (me), and Miles Davis (us) filled our weekends with music. Inspired by a Sam Tellig column I read around that time, I paired a Cambridge Azur integrated amplifier and CD player with a pair of Triangle Titus XS minimonitors. The sound produced by this quartet was clean, precise, and altogether pleasurable—for a total of about $1300.

It was January 1986. Stereophile's then publisher, Larry Archibald, and I were driving in his diesel 'Benz sedan from Las Vegas to Santa Fe. We had shaken hands at the just-concluded Consumer Electronics Show on my replacing J. Gordon Holt as the magazine's editor, and now, during the 750-mile drive, we mapped out the strategy to take what was then an "underground," digest-format, somewhat irregularly published magazine to the position of dominance in audio publishing it still enjoys.
