Just another person adding to the chorus...
My group watched some of the shows in both 341 and 541. The sound was just terrible. Booming echoes, little clarity, the space consumed almost all the high volume impacts and the AC hum was constant. Considering the price of tickets even on the 20 yard lines, this is an embarrassment for DCI. Tonight we'll be sitting 443 at $80 per ticket, which will likely be even worse.
I've been to finals every year since 1999, and next year will be a tough choice. I can't imagine that opening the roof would make much difference. On the plus side, the folks in Allentown shouldn't have any trouble selling tickets.
