I have to confess I am really bored with the whole conspiracy thing.
No SQ versions were used on these releases.
Abbey Road provided me with the Quad of 6 Wives and tell me it is from a tape. Why would they lie about it? (sensible answers only please) There is no reason whatsoever, especially as we are freely admitting when vinyl sources are used (as on King Arthur) and the decoded Quad of King Arthur we got sent was unusable as it sounded nothing like the stereo version sonically - and I mean nothing like it. So we hunted around and found a better quality CD-4 version. So AFAIK (and again, ABbey Road would not risk their name & reputation telling Lies, Andy Walters is a very highly thought of ME and also very good at his job - he would not lie about sources as he has no need or reason to and for that matter, neither do UMGi - after all, what's in it for them?
I like a good conspiracy theory as much as the next man, if not more than the next man but the emphasis here is on a good conspiracy theory whereas this is simply beyond nonsense.
I shall say nothing more on this now as there is little point
