It began for me in the late 70's with the good, old Hafler ambience extraction circuit which extracted an ambient rear channel signal by subtracting the L & R channels. Once I implemented that in my system, the increase in spatial aspects was so dramatic that I never went back to simple two-channel playback. I scrapped the Hafler approach years ago and now use a simple, modern AVR as a secondary amp that I feed the standard stereo signal from my preamp and set to surround mode to feed the two rear speakers. The AVR basically does what the Hafler circuit did (extracts the L-R signal) and amplifies it for the rear speakers. I have independent volume control of the rears and control of the delay time so I can set the effect to optimize the soundstage for any given stereo program. This approach has worked so well for me that I've never made the move to a discreet multi-channel system. The advantage is that it works with my very large stereo library of recordings as well as downloaded stereo files. I really have no desire to move to discreet m-ch since I get some much realism from this system.
I do agree, though, that a properly set-up discreet m-ch system is the best way to experience the advantages if one is starting from ground zero. Good luck!
