I wonder, since this clearly was an error, if they would remix and re-release it in the future. Rush was not happy with the mix of Vapor Trails and they re-did it.Using a number of different systems is a good and common practise. Things that sound great on the system you're mixing on might not reveal deficiencies other listening environments do, so you might back and forth a bit to make sure it translates well to other systems. Some classic monitors, like the NS-10, which at least in the old days, were the go-to monitors for mix, didn't really sound that great at all. But they were revealing, and the engineers learned to mix on it and knew the speakers inside and out. If you really know your system you can make good mixing decisions on them, even if they aren't perfect sounding.
As I remember it, Shirley took the mix and applied scratch mastering compression and limiting to it, so Steve could listen to it. Steve approved of the mix and they sent it out to mastering. They got it back and the engineer had attempted to fix what he thought was wrong with the mix. Steve basically said "this isn't our mix!" and decided they should go with the car scratch master.
