My personal opinion: a) 3D sound from 2 speakers Rubbish. Unless energy is arriving from the general direction of the supposed source, the best any system can do is present some psycho-acoustically confusing cues that attempt to fool the brain, but sadly (for the 2-channel snake-oil folk) the brain usually wins and tells you it is confused.
b) 3D sound in headphones Better. With customized HRTFs and a virtualized 3rd order ambisonic system (18 speaker feeds - 3 rings of 6) or simply really good binaural recordings this can work very well, source material dependent. If you want 3D sound, then you are going to need considerably more channels than 2. - Neil On Jul 8, 2011, at 2:09 PM, Bearcat M.
