Perhaps you'd like to explain exactly how would one go about this. In the case of The Guess Who's American Woman, the Q8 is said to have a channel error, yet the SACD transfer from the master tape has the same channel assignment. So it is really a mistake? What other point of reference is there besides the master tape? If there's no way to verify the correct channel assignments, should the reissue label just guess for themselves and hope for the best? Or should they play it safe and stick to what's written on the tape box, however illogical it may seem?
Not so long ago, everyone was so sure that The O'Jays' Ship Ahoy had a channel error, but it turned out that all the diagonally-panned instruments were intentional.
For me, if an quad SACD release features the same channel assignments as the old quad vinyl/tape release, then it's a win. If you like it better with channels switched around, fine, but the bottom line is that it's out there, and it's not like anyone's obligated to release these things...
re the diagonals, really good point, well made! i too thought they must be Sony SACD cockups for the longest time.. but then i found the channel assignments seemed to be the same on the SQ LP when decoded through the Surround Master and started to smell a wee channel assignment rat!! squeak squeak! time to get out the traps and shove the cat off the couch!
subsequently i somewhat stuck my neck on the block/ass on the line and some thought i must be borderline bonkers for suggesting those Ship Ahoy diagonals may have been intentional after all ("oh you don't do diagonals on SQ it'll make your decoder go schizoid!" etc.).. turns out Philadelphia Intentional, i mean International's, Quad remix blokey in charge Arthur Stoppe himself (no less!) said he and his fellow engineers mixed stuff using the diagonals to present a sort of phantom Centre position (i.e. a middle of the room Centre position, not Centre Front, not Centre Back, not Left Centre, not Right Centre but just "Centre" because the only other way to do so would be putting the same sound at equal energy into all 4 channels simultaneously and that would make your SQ setup go tits up, everything would cancel out to a momentary lapse of sound and all reason and logic would go to hell in a handcart!! maybe
err, where were we!? oh yeah! Guess Who!! whoops! sorry, i got carried away on a ship... a-hoyyyyyyyyy...!!!!
