Other way around I think you'll find... GEs have always done that. I used to prefer to fly Ansett wherever possible over TAA in the old days because I couldn't abide the whiny sound of the A300, it was like a constant droning while especially on decent and approach. DC-10s which mainly had GE CF6 also had that sound.
