If you do a Google search for "loudspeaker" combined with "full-range," "line source," "one-way," and "modular," you'll get results that match some, but not all, of the characteristics of the Ruel Audio R7. The Audience ClearAudient 16+16 comes the closest, with 16 drivers firing forward and 16 to the back, but its small full-range drivers are supplemented with eight 6x9" passive radiators, and it does not have modular construction. Plus, it appears not to be in production. For that matter, Google misses Ruel, but it has been granted a provisional patent.

It's day five of our planned month-long stay à Paris, late April through most of May. My wife is here for work—for me, it's strictly for pleasure—and we're enjoying Paris's rich, sensual goodness: food, museums, architecture, coffee, people, food. And yet, earlier today, when we were out for a walk—we've been walking close to 10 miles each day, exploring the city—I realized that my life here has been missing something important.

People often ask me how I listen to music when I travel. I play MP3s on my iPhone.

That answer always surprises, and sometimes disappoints: "You listen to MP3s?"

The response is moderately tempered when I add that I use good in-ear monitors (IEMs)—either Westone ES50s (ca $995) or Jerry Harvey Audio Laylas (ca $2725), both with eartips made from molds of my ear canals.

The Toronto Audio Video Entertainment Show (TAVES) has changed its venue. The show that now bills itself "North America's ULTIMATE Technology & Hi-Fi Show" has moved from the suburban Sheraton/Best Western location of the past two years to the Toronto Congress Centre, near the airport.

Why the move? Suave Kajko, President of TAVES, cites several reasons: the venue wanted to literally double the price for the large rooms; the Best Western hotel was the source of many complaints from exhibitors, and, in any case, is scheduled for demolition, and the show was bursting at the seams in terms of space (they didn't have enough space for booth exhibitors).

How many times have I asked myself what the purpose of music is? And what music really is, and what exactly I am trying to convey. What feelings? What ideas? How can I explain something that I myself cannot fathom?—Gabriel Fauré, letter to his wife, August 31, 1903

In writing reviews for Stereophile, I face a challenge. Whether I'm evaluating an audio component, a recording, or a live performance, I'm confronted by the fact that, when all is said and done, no one fully understands why or how the sound of a particular component, composition, or artist can affect us as powerfully as so many of them do. How and why music and sound moves us remains, fundamentally, a mystery.
