Sony SA-Z1 nearfield active speaker system

On top of a desk, an audio system must be able to deliver satisfying sound in a nonoptimal environment: a flat, reflective plane (the desktop) cluttered with keyboard (or maybe a laptop computer); a mouse; assorted papers, books, and trash; and, perpendicular to that, another flat, reflective plane (the computer display), which, if it's not a tiny laptop screen, will block some of the soundwaves emanating from the speakers. Such sonically inhospitable spaces can consign 3D stereo imaging (and other desirable sonic traits) to the realm of the imagination.
