Exactly Josh, good post.
Example of what you're saying; While attending Cedia this past year, I arranged to meet Mark Seaton and get a listen of his Catalyst based 7.4 rig he provided at a Datasat product launch (high end theater processing) at the Conrad hotel on Saturday night. Well, like most anything time was tight for setup and the Datasat folks utilized Dirac automated optimization to balance and tune the rig/room.
I got a good seat up front and the reps began their presentation about this extraordinary processor. They played some various clips, including BluRay concert footage of Rush live in concert. Upon completion, they opened up for Q&A, specifically asking about our perception of the system balance, etc. I was first to respond being polite, yet trying explain that the concert clip illustrated how far off the system EQ was. The other clips I had no frame of reference. But I explained having significant FOH experience, the balance was off,...way, way off. I elaborated using terms like lifeless, and anemic. I expressed that ballpark, the range somewhere below 200hz needed a ramp up of at least 10-20dB
They offered me a chance to recalibrate the EQ curves but I deferred to others there that were also interested in reshaping the response, but they were actually interested in buying one. With limited time, I thought I'd let those with the deeper pockets play with the thing, .... at somewhere around $15k-$20k, I'll stick with Integra myself. It is a bad ass, killer piece however.
Eventually, the balance and subsequent impact was much improved over the course of the evening. The acoustics were not as good as they could have been, thus the target curve interpreted the reverberant energy in a manner whereby there wasn't nearly enough bass to the mix. I mean come on, a Catalyst based 7.4 system with four SubMersives,....not counting the (8)8's in the surrounds, the mains and subs had (6)12's and (8)15's, this thing possesses some impact,...let's hear it!
And yes, as Josh alluded to, mixing live affords one the opportunity to increase the punch, impact and overall warmth of the mix of the associated frequencies, yet retain a nice balance and smooth intelligible midband for vocals etc, with the absence of any harshness.
Here's an overview pic of that demo evening, by this time of the night, the rig sound much, much better. Problem was many people had already left. We had fun though!;
