Threshold of a Dream SACD

I have recently picked up "Children's Children's Children" and "Question of Balance" on SACD by the Moody Blues. They are indeed SACDs (but no center channel - obviously taken from the Quad versions). Days of future past and threshold of a dream are also advertised as SACD 5.1 (says on the package label). The "In search of the lost chord" is advertised as stereo - is that stereo SACD or just ordinary CD Audio. I am very curious but will end up getting it either way for the bonus disk and remastered sound

Thanx inadvance
