Interesting, I thought it was quite different even after just one listen.Overall there’s not a ‘massive’ difference I could tell… But it’s starting from such a high bar… Some cool moments still though and was pleasantly surprised with a new real mix on track 4 - India.
Right from the beginning, the main guitar figure in "More Than This" that used to be in the rears is now in the front. As others have said, the center speaker is used a lot more aggressively to isolate the bulk of the drums, bass, and lead vocal. I can perceive phantom images left and right of center (for things like tom hits, some guitar parts, etc), which would suggest that the level of the center channel is as intended, but I did find the vocals slightly too hot in places. It also seems a bit 'wetter' than the 5.1 mix, perhaps because most of the reverbs and delays are now relocated to the height speakers.
