Way to go Debbie downer. I'm with Tom on this one all the way. My only question would be will 31 drum mics be enough?
I'm with Art on this one.
Yes modern processing can help a SINGLE cabinet (at least at ONE listening position), but it can nothing with multiple devices covering the same audience area that are more than 1/4 wavelength apart.
A single stack would be much better sounding-but also not as loud.
And (sad to say) it does not matter how good it sounds if people cannot hear it.
So you have to have a combination of BOTH.
Of course there was something to be said for having a whole "wall of sound" coming at you-even if it did not sound great (in terms of audio fidelity)-it WAS ROCK AND ROLL and that was the whole point.
Often the "experience" exceeds any quality considerations. This is true in many aspect of our lives-not just sound system.
Fun is fun-even if it is not perfect. And sometimes the "imperfections" are what make it fun and memorable.
You can take from that what you want but I'm just sayin'----------------
