Stereo equipment manufacturers have stepped right through the looking glass and are beckoning those with bulging wallets to follow them into the land of the mirror image. In their newest wonderland they have improved illusions to offer; so discard that antiquated stereo system you bought last year and prepare yourself for the latest reflections on the state of the art.

Recorded and reproduced sound, especially in stereo, is an audio illusion. REO Speedwagon aren’t really playing live in your living room (I hope), it just sounds like it because of a collection of electro-mechanical gizmo's relating to the two ears you hear with. Stereo sound depends on your two ears, and the fact that your brain associates certain distances and dimensions to particular sounds as they beat on your ear drums. Like the motion in TV and movies, the collective effect of the sound is an illusion that is quite convincing.
