This sign may not look auspicious, situated as it is over a trash basket. But this poster next to the exit stairs of the Kieferngarten stop of the U-Bahn, Munich's equivalent of the Bay Area Rapid Transit (BART) system's network of underground and overground trains, was essential for people walking from the train to Munich High End's home in the MOC.

Nor was it the only sign I encountered. Many subways stops—even the airport—displayed large posters announcing the annual well-attended Munich High End audio show.

Alexander Melnikov: Fantasie: 7 Composers, 7 Keyboards; Nielsen: Symphonies 2 (The Four Temperaments) & 6 (Sinfonia semplice); Beethoven: Violin Concerto in D Major (cadenzas by Jörg Widmann); Fragment from Violin Concerto in C Major; R. Strauss: Also sprach Zarathustra & Debussy: Jeux.

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."

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.

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.
