I would agree with that...it isn't the best DTS mix, nor is it among the best discs I've herad, but it is still quite good. Compared to some of the better ones I have, the vocals in the center seem to lack a bit at times - the front blend isn't quite right, almost like being there live but not in the best seat... It isn't nearly as good as the DVD-As, but I didn't expect it to be either. I felt they played better when I saw them in person, though the sound at the show wasn't exactly great either (not related to their performance though...).
I know exactly what you're saying. I don't know if it is the mix or the way they played, but they didn't sound "on the money" on some of the tracks on the disc, like it was their first show with no rehearsal or something. They didn't sound like that at the show I was at.
The one track I like the best is Hate Song. During the solo, the guitar pans all the speakers rapidly and it sounds great. A nice little effect that you would obviously not hear at a show, but fun none the less. They did that also on Arriving Somewhere, But Not Here as well.
