but yeah, the upgraded BMW Individual Audio in my M3 is pretty damn good also. Dirac technology really works and makes even compressed music from Sirius and my iPhone sound great.

I just looked it up, and found out that the new Acura RL does have DVD-A playback ability. I need go to a dealer and play with it to feed my curiosity.

The systems they have in the Lexus and S8 are particularly excellent, although I have a feeling the generous sound insulation built into those luxo-barges are one of the main contributing factors in the sound quality. My M3 is less insulated but still sounds almost as good.
