It's like hearing the name of an old friend and then seeing him, in your mind's eye, as he was when you were both much younger: Whenever talk turns to Boulder, Colorado–based PS Audio, I can't help picturing that company's Model IV preamplifier, of the early 1980s—most likely because that was the preamp I longed to own at the time. (Tragically, I couldn't afford to buy it, so I struggled on with my NAD 1020.)

I've always considered the high end to be industrial art. People who favor a certain brand are saying, in a way, "I like that designer's interpretation. I like his or her art."—David Wilson

Last March, I had a rare experience akin to hearing the same recording through two different systems. I heard Andris Nelsons conduct the Vienna Philharmonic Orchestra in the same program—Haydn's Symphony 90, and Brahms's Variations on a Theme by Haydn, followed by his Symphony 3—in two very different venues: UC Berkeley's Zellerbach Hall and, 50 miles north, Sonoma State University's Weill Hall.

"It's not your average gal that drinks bourbon neat, walks around with a pocket atlas and drives a big white gear van. I thought she was charming and awfully funny."

When we next hear of her, she's in Nashville as part of a husband-and-wife folk/country duo, The Gabe and Amy Show, who released a single, "Blankets of Love," b/w Johnny Cash's "Big River."

Snatching my prize for best sound on the third floor, the world premiere of the new Wells Audio Innamorata Signature amplifier ($13,000), enhanced by the new crystal technology in Jack Bybee's A/V Signal Enhancers ($119.95) and Bybee Technologies power cables ($1500), blew me away. Whoever expected, on Reference Recordings' new Kansas City Symphony recording of the suite from Prokofiev's Love for Three Oranges, such impeccably detailed, superbly controlled full-range sound in such a small room?

Sundays customarily draw a smaller attendance at shows, but CAS's Sunday across from San Francisco International Airport was especially slow until, surprisingly, things speeded up shortly before the runway was in sight. Either lots of audiophiles spend their Sunday mornings in church, or they're too occupied with family, brunch with friends, or hangovers to get a move on before noon. Happily, things were not at all slow in the room shared by Burwell & Sons and Raven Audio . . .

Mincing no words, Audioengine's Brady Bargenquast declared, "Bluetooth usually sounds like cat shit. Therefore, when we designed our wireless B1 Premium Bluetooth music receiver ($189), which just started shipping last week, we did four things to ensure good sound quality and satisfactory listening . . .
