I'm guessing they probably had intentions of doing a 5.1 remix after how well the 5.1 SACD of Toys in the Attic came out so they probably recalled the few thousand copies of this stereo SACD and had them destroyed. It seems like a handful must've ended up in the distribution center of one of those music wholesale blowout companies, and from there to the wider public. I've heard a bit of this SACD and to anyone lusting after it, I'd say save your energy (and money) - it was mastered for SACD by Dave Donnelly )the same guy that did the over-loud Chicago expanded CD remasters for Rhino) and it has at least 2dB of dynamic range lopped off compared to the old CDs. Whatever he did to the SACD didn't improve it, it just exaggerated the boxy, midrangey sound of the original mix.
To bring this back on topic, I've noticed that every version of the quad mix, including the SQ LP, the Q8 and the quad version on Tidal has a very noticeable treble response issue in one of the front channels for the final two songs (Lick and a Promise and Home Tonight) which makes the lead vocals, amongst other things, lead heavily to one side. I used to think it was just an issue with the copy of the Q8 I had, but given that it's even on the Tidal version I have to conclude there must've been some kind of tape alignment issue or something during the quad mix. So if you're doing your own conversion or remaster of the quad mix, look at treble-matching (ie make the bad one sound like the good one) the front channels for the last two songs, it greatly improves the sound of the mix.
