CBS had specific goals for the development of their SQ matrix (full LF/RF and LB/RB decoded channel separation, for example).
In another thread, there's a lot of discussion about the SM in QS decode mode providing very good fake surround sound from a large number of stereo sources.

Any info about what sort of listening tests/evaluations Sansui did to arrive at their "magical" QS decoding equations - a more detailed history (similar to the surround sound investigations that CBS did to arrive at SQ)?
