I hit the ground running Sunday morning, with many rooms to visit but only six hours to do so. I started with the 16th floor suite featuring horn speakers from German company Avantgarde. Pink Floyd's "Another Brick in the wall" was playing on the humongous, four-way Trio XD horn system ($150,000 with four bass horns) and the kick drum did indeed kick me in the chest. (Peak spls, measured with the Studio Six iPhone app, reached 102.3dBC, slow.) Rest of the system included Esoteric source and amplification, Transparent cabling, and an HRS racks. There weren't any colorations that could be laid at the feet of the horns, though voices were projected forward in the soundstage. An extraordinary sound and a great way to start the day.

I remember the sound character of early (1990s) Audio Physic loudspeakers. They were the first radically slender floor-standers. They generated humongous soundstages, and precise imaging was their raison d'être. Users would position the speakers extremely far apart, usually on the long wall. They used plenty of toe-in, crossing the speaker's direct waves in front of them. Finally, the listener would sit closer to the speakers than the distance between the speakers. Their side-firing woofers made tight-ish bass, but, if memory serves, their midrange, though quite clear, was less rich and dense than I prefer.

"The core audiophiles, they are aging," the collective subconscious of exhibitors on the 15th floor seemed to say. "Since they're attempting to bask in the glow of their golden years, they don't want to hear anything in their sonic sanctuaries that might expose them to the harsh realities of the present day. Hence, we shall warm up the sound, add a few tablespoons of sugar, and ensure that everything sounds as safe, warm, and cuddly as those TV commercials for assisted living communities."

With very few exceptions, the 4th floor of the Renaissance Schaumberg was filled with fine to extraordinary sounding rooms. The sound was so good that Jana Dagdagan and I returned to the floor on Day Two to shoot video in three of the rooms. You'll see what fun we had (in very cramped quarters) when the video appears down the road…
