Here is a case where the SM salvages a title: George Harrison All Things Must Pass (CD-2001 Remaster). This CD is a reverberant mess with DPLIIx Music and even worse with Logic7. Although the title remains in dire need of De-Spectorization, it is actually a listenable surround sound experience with Involve 4(.1). (Note that the quieter songs are still the most listenable.)
