There was once an Englishman named H.A. Hartley, who was a contemporary of H.G. Baerwald, P.G. Voigt, P.K. Turner, and other men whose first two names are lost to us. Hartley was a capable designer and audio theorist, not to mention a gifted lecturer and writer—his literary achievements include a book on astrology (footnote 1), of all things—and he's often credited with coining the expression high fidelity. Most important of all, in 1928 H.A. Hartley teamed up with the aforementioned P.K. Turner to create an audio manufacturing company known as Hartley Products, Ltd. The Hartley company made electronics and loudspeakers, the latter of which included full-range coaxial drivers using energized field coils and, later on, quite powerful permanent magnets—just like their countrymen at Lowther Loudspeakers, Ltd.
Analog maven Wally Malewicz is no stranger to these pages. His first commercial product, a cartridge-alignment tool called the WallyTractor, became a hit among the vinyl cognoscenti after Michael Fremer wrote about it in "Analog Corner" in the November 1998 Stereophile, and Malewicz's full kit of Wally Analog Tools was the joint winner of our Accessory of the Year award in 2002.
My opinions keep changing—more evidence of life before death, I suppose—including my thoughts on audio-system hierarchies. I used to think that preamps were among the most sonically influential components, certainly more so than power amplifiers. I'm not so sure anymore (footnote 1).
Yet another of the best systems I've ever heard at a hi-fi show was an exhibit by some former distributors for the English manufacturer Exposure Electronics, at a Chicago Consumer Electronics Show in the late 1980s. The exhibitors seemed to believe it was better to impress with a humble product than to overwhelm with a full-bore assault, because they limited their display to a single amplifier: the then-new Exposure X (as in "10") integrated, mated to a record player comprising a Linn LP12 turntable, Ekos tonearm, and Troika cartridge, and a pair of Linn Kan loudspeakers.
