It's a weird social psychology quirk. For whatever reason, the entire music industry has been captured by the delusion that mixing all the sounds louder is good. No one likes it, except for those guys. For reasons I'll never understand, the movie industry has been captured by the opposite delusion; they're going to pump dynamic range so high that you can only understand about half the dialogue in the movie. And of co…
The full dynamic range is nice if you actually want to experience it and have a system capable of reproducing it. A dedicated center channel with a few hundred watts of amplification behind it will cut through the ambient backdrop like a hot knife through butter. You can watch Transformers or MI3 at reference volume with crystal clear dialogue if you're willing to throw enough power at the problem.
Am I meant to then override that by increasing the center channel volume so it's louder than the other speakers?
Or raise the system volume?
