While there's not much else I can do about SFX, there could be less dialogue in side channels than in JP/IT/FR audio, which I have.
Provided it's at the right pitch and nobody messed it up. Saying that because I checked the American dub for the final movie that someone uploaded on nyancats and, while the monologue in the opening isn't in side channels, the actual audio/music sounds like someone EQd the heck out of it compared to JP/IT/FR.
Of course the DE audio could always be worse/less useful...
