AXPONA 2023

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.

There's nothing quite like starting off the show with a million dollar system. Holding court in the huge Schaumburg D partition of the Convention Center, the imposing Estelon Extreme Mk II bi-amped loudspeakers ($269,000/pair) received their juice from two Vitus Audio MP-S201 Mk I stereo amplifiers ($230,000/total) via Crystal Cable Art Series cabling ($330,000). But they were just the start of a system where each amplifier required three power cables, put out up to 500W/pc into 8 ohms and 1000W into 4, and weighed more than I can type without getting back spasms. (Okay: Each weighs 125kg. I don't dare convert that to lb.)

Two months ago, at the audio expo in Tampa, I stumbled upon a pair of most intriguing French speakers. The $8000/pair Diptyque 107 is a medium-sized planar magnetic whose designers, Gilles Douziech and Eric Poix, make no secret of their love for Magnepan. All the same, the duo has sought to improve on that company's famed panel technology, mostly by addressing a perennial shortcoming of such dipoles: their lack of deep bass.

As I think I wrote somewhere, it's one thing to hear equipment at a show, another thing to hear it at home. I meant to imply that, of course, at home is the only way to truly hear a piece, in your reference system.

But at AXPONA, where George Counnas (center) and Carolyn Counnas (right) debuted their new Zesto Audio Eros 500 Select KT-150 equipped, class-A monoblocks, with Zesto Audio's Leto Ultra II preamp, which I reviewed in January 2021, I was flummoxed at the beauty of sound, extravagance of liquidity and detail, and nearly spiritual physicality the system endowed to a variety of music.

Grandinote owner/designer Massimiliano Magri (above) joined his North American distributor Reinhard Goerner at AXPONA for the premiere of the Grandinote Premier Mach 8XL loudspeaker ($30,800–$33,000/pair, depending upon finish). According to Grandinote's endearingly "English as a second language" website, the Mach 8XL's eight full-range drivers utilize a special treatment behind the drivers' membranes that prevents cone break-up. The drivers roll-off above 13kHz, allowing a super tweeter that handles harmonics above 7kHz to come to the fore. Rather than employing a crossover—the Mach 8XL has none—drivers are modified to create "a solution in the middle between bass reflex and transmission line."

Several surprises awaited in the AXPONA room sponsored by Gary Leeds's Hear This, North American distributor of WestminsterLab, and Von Schweikert Audio in association with Lampizator, NA and Small Green Computer. (Bonus points if you can read that out loud on one breath.) First was the "hard launch" of equipment from WestminsterLab: the Rei monoblock ($32,900/pair), which despite the title is not recommended for summer hikes in Yosemite, and Quest balanced preamplifier with full carbon-fiber component shielding upgrade ($25,100, or $22,900 in basic configuration). Next were the speakers—not the usual behemoths usually transported to shows by Von Schweikert Audio, but rather their smaller Endeavor SE ($27,000/pair plus eight Critical Mass Systems footers that cost $650 each).

Jeffrey Catalano of Lower Manhattan lives in an ancient building near the South Street Seaport where ghosts of seaman and slaves mingle with investment bankers and tourists. Catalano's High Water Sound is the place where every New York City area audiophile dreams of being invited, cause it's here where this mad audio wizard (and former jazz drummer (1957 Ludwigs) and jazz LP collector, like moi) cooks up the magnificent sounds that appear, like magic, at every show where High Water Sound presents. Year after year, show after show, as consistent as Big Ben.
