I've seen this LP mentioned a few times in the archives and I have come to the conclusion that this LP is not and never was in quad although the US release says it is. I have listened to the US LP, the original German pressing from 1970 and the CD reissue and all have equally bad separation in SQ, QS or vario-matrix modes. In fact , there is no difference between either in stereo, so I would have to conclude that the supposed "quad" mix on the US LP (1973) is the same mix as the 1970 release. I doubt that a pre-quad mix from 1970 could suddenly morph into a quad mix when released in 1973 when they both sound exactly the same. Any comments?
