Shocking 3D sound in 2 channel


I've had it happen a few times where my brain actually thought the center image was real. Somehow the imaging lined up so well that my brain sensed physical objects in front of me - not just a believable illusion.

Can all speakers do this if set up right? Are there some that do this without fail? Was I just imagining it?

Accurately recording the ambient information of an actual venue and music event, takes careful mic placement and is the most fragile(easiest lost)of what is contained in your audio signal. Your entire playback chain, source to ear, is responsible for it's preservation. On the other hand; Amused to Death, and quite a few other albums, were mixed/recorded using a system called QSound, which(via an algorithm) enables even a simple and inexpensive system to throw images that can amaze and entertain: (http://en.wikipedia.org/wiki/Q-Sound)
BTW: I've heard crappy pressings of the Amused to Death CD(exact same Columbia UPC 074644712728) that miserably failed to reproduce 3D effects, when compared with a good disc, on a system that performed wonderfully. SO- If you do try the Roger Waters, and it doesn't perform as expected; it may not be your system.
Mr Moon- An easy case to make, in general(ambiance recovery/vinyl vs CD). I'm guessing your friend has quite a record collection? Would they be interested in adopting a new son?
The following provide tests, with which one may determine whether their system actually images, or reproduces a soundstage, as recorded. ie: On the Chesky sampler/test CD; David explains in detail, his position on the stage and distance from the mics, as he strikes a tambourine(Depth Test). The LEDR test tells what to expect, if your system performs well, before each segment. The Chesky CD contains a number of tests, in addition to the LEDR. (http://www.chesky.com/various-artists--jazz-sampler-amp-test-volume-1.html) (http://www.audiocheck.net/audiotests_ledr.php) BTW; The shape of your ears' pinnae is also a variable, regarding your ability to perceive images/locate sounds.
