CBS Labs published many technical articles about the development (including listening tests) of the SQ matrix.
Sansui also published some articles about the development of the QS matrix.
In 1974 and 1977 the BBC published listening tests of SQ and QS (links are elsewhere in QQ). Both SQ and QS didn't do very well in terms of sound localization.
CBS Labs, Sansui and the BBC all had/have a fairly high level of credibility on audio and technical matters in general.
Anyone have any ideas as to why both CBS and Sansui (through listening tests and other scientific measurements) concluded their matrix systems offered good performance whereas the BBC tests showed this to be questionable?
