I suppose that someone ought to mention-so I shall-- the Carver Sonic Hologram. You can still find the devices around(they were crosstalk cancellation processors). They work really well, if you do not mind sitting really still in one spot (which of course you are going to have to do for any such system with only two speakers). And the nice thing is the Sonic Hologram sounds good- it does minimal damage to the music.
It is interesting--sort of tells you where the industry was and still is on surround and so on--that Martin Colloms writing about the Sonic Hologram in HiFiNews says that it definitely makes stereo better [and potentially much better] but that it is just too much trouble...
