  There is no mystery in how the machine works, really.  A very crude analogy is how they used to put a dark blue filter on the camera to simulate night scenes in movies.  It was cheaper and more practical to shoot during the day hours.  However, if you looked closely, you would see everything casting shadows despite the supposed night time. 

But just like early moving pictures fooled the viewers, I am sure this machine will create a very interesting soundstage effect that eventually the listener may become able to discern. 
Adrian,

I know what you are saying and it is might be true. Well, it might be true in terms of artificial soundstage reproduction as soundstage is the artificial subject itself. Still, if the K-Audio device works in trim of spatial improvement then it might be interesting as we have a lot of room to go in spatial audio. The spatial information is recorded, preserved and reproduced by “other” means. The mainstream audio does not deal with spatial complexity of recordings. Too complex, too expensive, too difficult to sell, too difficult to monitor…. etc, etc…

I certainly do not automatically presume that K-Stereo devise might operate at the level of “imaging without soundstage”. Looking at what they say and promise it looks that their awareness still is confided in soundstage prison. However, they say what they are able to sell and in the language that might be understood by their consumer.  They name a frustration around which the audio person’s mind is rotating – namely “a wide and deep soundstage”  - and they offer a devise that produces an improvement in that area.

Does the K-Stereo screw something else? Does the K-Stereo deliberately or not affects the spatial presentation?  I do not know. However, I very much welcome any ideas that toy in this direction. I like idea of microphone that “process” the near-sound and far-sound with a certain level of “smartness” (similar to what out hearing does). I like electronics that deal with space like a hot scooper deal with ice-cream. I like loudspeakers that destroy division between the “beginning of soundfield” and “end of the soundfield”… So, to me, the more devices that expand our “dangersness” in spatial reproduction the merrier. You might be correct and many of them will be usable juts conditionally or be just turn out to be plainly bad but it is how the experience is building itself up – with exposure to many different opportunities, trying to educate ourselves with what “works”, why it “works” and what might be the algorithms for success…
