It seems the obvious way to build a loudspeaker: one driver, no crossover, full range.

Instead, most speakers work this way: Complicated electronics split the audio signal into pieces, adding various colorations and phase shifts along the way. The pieces are distributed to different drivers, each of which adds another unique set of characteristics. We then expect these fragments of electronic signal to be brought together again in a continuous, coherent reproduction of music. We agonize over different cable routings or which contact cleaner to use, and yet we calmly accept this grotesque sausage-making way of building speakers. It's ludicrous.

I received a very kind note from Owen McCafferty, who, along with Ben Meadors, hopes to travel to Portland, San Francisco, Chicago, Cleveland, and New York City, meeting vinyl collectors, record store owners, and other vinyl enthusiasts, to discuss why vinyl is important. The duo will document their journey and publish a book detailing their experiences.

A week ago, when we first caught up with Owen and Ben, they were about $2000 away from the funds needed to support their Kickstarter project.

I was delighted to see so many people at the 2011 California Audio Show so attentively listening to music, as though listening to music on the hi-fi in 2011 is as much of an event as watching an episode of “True Blood” on Sunday night, or attending a concert at a music hall. Of course, we know that listening to music on the hi-fi is a special event, an active, enriching, and entertaining experience, worthy of our time and energy for the joy and nourishment it brings our minds and souls. It’s a lot of fun. If you were present at the California Audio Show, you experienced this.

While many exhibitors at the California Audio Show struggled with the sound of their rooms, employing careful, creative speaker placement and a variety of room acoustics treatments, SimpliFi Audio’s Tim Ryan seemed happy to ignore the room altogether.

Made in Sweden and now represented in the US by SimpliFi Audio, the DLS Flatbox on-wall loudspeakers come in five sizes (Mini, far right: $249 each; Midi, center: $349 each; Slim Large; Large; and XL, far left: $499 each), can be hung horizontally or vertically, and are available in variations of white and black cabinets and grilles. There are also three subwoofers, including the Flatsub8 ($799), used in the room. Partnered with Resolution Audio’s Opus 21 system and inexpensive DNM cables, the speakers threw a surprisingly wide stage, despite being mounted on temporary plywood walls. As we went up the line, I noted greater bass extension, but the Midi version seemed best balanced with the room and subwoofer.

Through a system built on all-Linn electronics (Akurate DS: $6990; Akurate Kontrol: $6500; Akurate 2200 power amp: $5200), Tannoy Definition DC8 loudspeakers ($3600/pair, in lovely Espresso Walnut finish), and MIT cables, we listened to a series of short excerpts of hi-res demo material, from female vocals to a familiar drum solo off the good, ol' Sheffield Track & Drum Record.

I walked into the Margules room and was welcomed by Peter Frampton’s funny cover of Soundgarden’s late grunge-era hit, “Black Hole Sun,” with all the fuzzy, phasey, talk boxy effects you might expect from Frampton held perfectly in check, well-focused within the wide soundstage.

The attractive Fritz Speakers Carbon 7 ($1750/pair) were matched with ModWright KWA 100SE power amplifier ($3995), ModWright LS 100 tube preamplifier ($3495), Esoteric SA60 universal disc player ($4995), Zesto Audio Andros PS1 MM/MC phono stage ($3900), and Thorens TD 309 turntable ($1900). WyWires provided the speaker cables ($1299), interconnects ($849-$1299), and power cords ($329). Room treatment was by GIK Acoustics and ASC. Steve Blinn Designs contributed the equipment rack ($1899). Billie Holiday’s Songs for Distingu&#233 Lovers (priceless) provided the mood.

We listened to a track from Nat King Cole’s Love is the Thing, a beautiful 45rpm reissue from Chad Kassem’s Analogue Productions.

There was a jovial, festive vibe in Philip O’Hanlon’s On A Higher Note room, featuring Luxman amplification and source components, Vivid loudspeakers, and music courtesy show attendee, Raymond.

As I walked into the room, O’Hanlon explained that Raymond had been knocking everyone’s socks off with his vinyl selections.

“As much as I like the music I brought, I’m also kinda sick of it,” O’Hanlon chuckled. “What’s next, Raymond?”

Raymond dug through his bag of vinyl and handed O’Hanlon a record. The charming host took that record and placed it on Luxman’s PD-171 belt-drive turntable ($6200, including tonearm and dustcover), the first turntable to come from the Japanese company in 28 years.
