I suspect, though not entirely sure, that a lot of folks simply look at peak SPLs in live events and feel comfortable when their own systems can go as loud, or even louder. But, from my standpoint, this not the entire picture on dynamics; dynamics include both scaling up and out; "up" as in how loud you can go, and "out" as in how much body to the sound is added at the same time. That scale-out is just impossible to achieve, but anyone feel free to tell me I need to get out more. And part of it, again, is limitations in the recordings.
BTW, If anyone has ever been to NYC's St. Patrick's Cathedral on 5th Avenue for Sunday Mass when the organ plays - and I assume most probably know how enormous that place is - you will likely be in suspended disbelief at the amount of power coming out of the organ, filling that entire gargantuan space. I feel it is a shocking experience, especially that body of sound, never mind the SPLs.
