Some believe that Dolby Atmos, Apple's spatial audio variant, and other immersive technologies are the wave of the future. While the best way to determine what the future will bring is to live long enough to render the future the present, Jim Austin and I independently dipped into Focal Naim's impressive self-contained 7.2.4. Dolby Atmos Theva exhibit, staged within their larger exhibit space, to get a taste of what's available right now.

Credo Audio Switzerland's Cinema LTM loudspeakers ($199,995/pair) may have towered above all else, but the gear from EMM Labs and their lower priced Meitner Audio line, van den Hul, VPI Industries, and DS Audio displayed in another "give it all you've got" large room was nothing to scoff at. Though I've grown tired of the overblown sound on Gary Karr's LP, Adagio di Albinoni, I was awed by the midrange beauty of Sara Barreilles's voice on a 24/88.2 file of "Goodbye Yellow Brick Road." The recorded sound of this live performance seemed uncannily real, and the soundstage was awesome.

Air-walled exhibition rooms are one of the biggest challenges at audio shows. With no solid surfaces, many exhibitors in the large rooms on the first and second floors of the Schaumburg Convention Center had no choice but to struggle to put their best face forward.

Dynaudio and Octave probably had it better than most because, at the end of a row in Utopia D, presumably two of their walls were solid. Their sound on their biggest system certain was solid and all-of-one piece, yet extremely smooth. It had lots of life and flow, especially if you listened to LP and sat in the first row where the sound was at its tube splendor wettest and the low bass clearest.

I'm not one for abusing punctuation, as in ending every sentence of a press release with an exclamation point. (It happens more frequently than you may wish to know.) But when MBL named its top-of-the-line loudspeakers X-treme ($398,000/pair), they weren't kidding. These speakers are as huge as they are imposing.

The room was noisy, and the switching between selections a classic case of trackus interruptus. Nonetheless, the ability of Atohm's GT1 bookshelf speakers ($4499/pair) to convey bass far more powerful than one might reasonably expect from speakers of their size left me smiling. I was smiling as well because the first demo track chosen to display this wonder was one I occasionally reference for color, texture, and speed: Yosi Horikawa's "Bubbles" (16/44.1Tidal/First World Records).

Trigger warning: If sky-high prices for audio gear make you gnarly, this AXPONA report (and many others) won't lift your mood. Just the MasterBuilt-brand cabling in dealer Scott Walker Audio's room carried a heart-stopping six-figure price tag.

The space, featuring Von Schweikert Ultra 7 speakers ($180,000/pair), wasn't especially small or large. Let's call it a Goldilocks room. Leif Swanson, Von Schweikert's chief designer, said that the brand's products had often been demoed in big expo rooms, which occasionally scared off potential buyers who assumed that the speakers needed a jumbo-sized space to sing. Not so, says the company.

Room 352 at AXPONA, where cable constructors Shunyata Research and speaker builders Clarisys had joined forces, was something of a feast for the senses. The Clarisys Minuet speakers ($38,800/pair) look like high-tech heaters in a 1940s film noir, and I mean that in the best possible way—I love how they seem simultaneously retro and thoroughly modern. They sounded wonderful too.

Masimo must have been the biggest, most valuable company at AXPONA by far. Its market valuation is slightly north of 10 billion dollars. The NASDAQ-listed firm had more than two billion in revenues last year. And yet it's a safe bet that most expo-goers who saw the Masimo name on one of the demo rooms thought, "Who?"

Colorado's Ayre Acoustics jammed a big system into a small room at APXONA, wall-to-wall attendees barely leaving space for Ayre's president, designer, and Chief Ayre-Head Ariel Brown to press the flesh and discuss the gear.

I probably spent much of my time at AXPONA with a severe case of resting bitch face, as I'm usually concentrating hard. There's a lot to cover, and a thousand facts to get straight. But during system auditions, I occasionally smiled too, sometimes unintentionally making eye contact with exhibitors who were excited to see that I was excited.

That's what happened in the Linkwitz room, where CEO Frank Brenner and noted Linkwitz evangelist Charles Port were demoing the company's LX521.4 open-baffle speakers.
