They also split the duties from one amplifier to a 2-piece system (the Receiver Audo Module, or RAM, and the Booster/Amplifier) for the Harman Kardon and Bowers and Wilkins systems.
Not sure if the change from MOST optic to ethernet would cause the difference in sound quality or if it would be more the way the 2 cars are set up differently.
