Although I don't believe the articles intended audience was necessarily the audio playback crowd and aside from being something very well written about my favorite subject-audio, and how often does one come across that, I was particularly intrigued by a box that could provide 3D sound. It's been an elusive and kind of a grail type quest that I've encountered to varying degrees through various system changes. I had subscribed to the conventional wisdom that source was where it all starts and speaker/room relationships were key to gettin her done. If I'm to take the author at his word and ancillary equipment and room questions aside,my audio world view has been rearranged.  a '13 iPod MP3 blue toothed the Stones into the room?  Anyway the article is an archived one and little has come of this majik black box, that I'm aware of anyway and at least for now can rest but for how long who knows that all my hard work and money hasn't been misplaced. 
fourwnds,

       Dr. Choueiri of Princeton has a website devoted to his 3D audio research.  This is a link to the site:
