After all the tweaking was complete, I became fully aware of a highly transparent, wide, and deep soundstage, featuring well-defined image outlines. On a well-recorded choral track such as “Shenandoah” by Cantus, I was startled by the 3D presentation of individual voices. It became clear that the AMG One could deliver a spatial impression that most solid-state amps can only dream of. Bass extension and impact were superb. Upright bass pitch definition was spot on, while tympani strikes took off with satisfying punch. Even in a fairly large room, power reserve was adequate for the DeVille. Transient speed and control were also noteworthy, which accounted for vinyl surface noise being non-intrusive.
