Musical Surroundings’ impressive setup included the new entry-level Rockport Atria II loudspeaker ($26,500/pair). More efficient than its predecessor thanks to a new tweeter waveguide—itself trickled down from the top of the line, and intended to create a more uniform dispersion pattern and allow for better driver integration—the speaker has also been re-voiced. “It sounds radically different,” said Musical Surroundings’ Garth Leerer. Alas, without knowing how many more rooms I had to visit before flying home, I simply had too many unknowns ahead to pause long enough for a decent audition.
