Here's to hoping the live sound is better this year!
What's changed in the past 5 years to make it worse though? The FOH engineer has been the same at least as far back as ToT. Many people have commented that this was the worst sounding DT show they've seen in their respective venue, so I don't think that house stacks are to blame. Someone on GDT blamed digital PAs (I assume the mixboard specifically, as class-D amps are supposed to be incredibly good) for adding the ability to oversaturate the sound with effects.
