Mick Survance of Quintessence Audio in Morton Grove, IL knows his brands well. Wilson Audio, Dan D'Agostino Master Audio Systems, Clearaudio, DS Audio, dCS, Transparent, Bassocontinuo, Sonus faber, Boulder, Critical Mass Systems, Hana, and Kubala-Sosna: these are among the major, time-honored brands that fill the homes of many audiophiles with means.

Each of these rooms had several elements in common: premium equipment, meticulous set-up, and heavy black draping that, while necessary to reduce multiple issues in narrower air-walled spaces (which were nonetheless larger than my music room), also reduced three-dimensionality and air. It was thus a wonder that individually as well as collectively, Quintessence's showcases produced some of the best sound I encountered at the show.

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."

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).

Harmonic Resolution Systems (HRS) unveiled its new, significantly less expensive EXR-1921-4V audio stand ($7795) at AXPONA. (I'd originally seen this stand at Definitive Audio's private Music Matters event in Seattle.) Put to good use in the Ultra Fidelis Room, it joined HRS's SXR-1921-5V audio stand ($11,550/frame), M3X2-1921 isolation base ($3995), R3X-1921 isolation base ($1975), and Vortex V150 isolation feet ($1630/set) to support a system that included Vandersteen M5HPA High Pass Amplifiers ($16,800/pair) and Kento Carbon loudspeakers ($41,700/pair)...
