LATEST ADDITIONS

It's noon and a sunny 76º, and already people are setting up for the inaugural Florida Audio Expo at the Embassy Suites by Hilton Tampa Airport Westshore. No sooner do I walk into the Dynamic Sound Associates room than someone asks me if I can please hold three long and hefty Luminous Audio power cables. With those monsters hanging over one shoulder, I snap my first photo.

Peter J. Walker (1916–2003), founder of Quad Electroacoustics and designer of some of the most well-regarded products in the history of domestic audio, famously believed that a properly designed audio-frequency amplifier should have no sound of its own. As for suggestions that his Quad II amplifier (1953–1971) sounded better than most, Walker was unmoved: "We designed our valve amplifier, manufactured it, put it on the market and never actually listened to it."

The main inherent advantage of the full-range electrostatic loud speaker system is that it allows a single diaphragm to embody the conflicting attributes needed for optimal performance at both extremes of the audio range. Its thin-membrane diaphragm can be made exceedingly light, for superb transient response and extended HF response, yet it can be about as large in area as desired, for extended LF response.

Editor's Note: 24 years ago, in January 1995, we published the first issue of Stereophile Guide to Home Theater, a sister publication intended to appeal to the the growing number of home-theater enthusiasts. Stereophile's founder, the late J. Gordon Holt, had gotten early into the idea of accompanying movies with high-quality sound, and when I first visited his New Mexico home in January 1986, his system included an Advent NTSC-format video projector.

In the 1990s, while putting together one of my early hi-fi systems, I'd often visit New York City audio retailer Sound by Singer to gawk at their top-tier wares. On one such visit I noticed a serious-looking gentleman listening to Stravinsky's The Rite of Spring through a pair of Audio Physic's Step loudspeakers (accompanying electronics long forgotten). Sitting on their dedicated, minimalist-looking metal stands, the pint-size Steps were angled up 22° or so, to create a physical time alignment of the tweeter's and midrange-woofer's wavefronts. The Step looked odd—kind of scrawny. But these petite minimonitors projected music that seemed to exist entirely free of their cabinets, pulling off a sort of "disappearing" act I'd never before heard.

Friday, February 1, 2–5pm, and Saturday, February 2, 1–5pm, Big Kids Toys AV (1413 Garland Drive, Greensboro, NC 27408) is holding listening sessions. Products being showcased will include Luxman's L-505uXii integrated amplifier and new PD-151 turntable, as well as loudspeakers from Triangle, including the Magellan Cello, and the Esprit Australe EZ and Esprit Titus EZ.

In the late 1980s, when I began reviewing high-end subwoofers, they were big and heavy, difficult to move or find space for in a room. Their controls were always on an inconveniently positioned rear panel, and there were no built-in automatic room-optimization options or parametric equalizers. Velodyne's 105-lb, downfiring ULD-18 ($2570), ca 1989, was typical: Two people were needed to unpack and move it; it was powered by an outboard 400W amplifier, connected inconveniently with a speaker cable and an RCA-terminated interconnect for its servo control; and its controls were on the bottom of the cabinet. Changing its crossover frequency involved soldering new resistors onto a printed circuit board inside the amp.
