I once told Stereophile publisher Larry Archibald it might be worth, say, a 10% loss in sound quality with CD not to have to jump up and turn over the damned record. Sometimes a CD saves you from popping up twiceMahler's Fifth or Bruckner's Seventh on a single disc instead of three LP sidesor three timesMozart's Magic Flute on three CDs instead of 6 LP sides. That might be worth a 15% sacrifice.
