It's been said that CBS was pretty cheap with production at the time and used the SQ vinyl stampers much longer than they should have...
This would make sense. An interesting side note, I did leave SQ mode on my Sansui QRX 7001 when compared with the Tidal version and it decodes nicely... I know Lotus has only quad masters, but is it possible the version of Santana III on Tidal is in fact an SQ version by some coincidence? Other than not hearing weird "phasy" sounds I don't know how to tell.
