I agree 100%. I've had a system in a number of different room sizes, shapes, ceiling heights, etc over the many years that I've been involved in this hobby. In some locations, I could hear the issues. Wasn't smart enough to do room treatment.
My son is a musician and has recorded in a studio and done his own recordings. He's way more knowledgable about the techie end of those things. He was absolutely convinced that I would benefit from room equalization, so I downloaded a trial version of Dirac Live and bought a recommended mic. He measured my room and we found that it actually measured pretty flat. We tried the room equalization and didn't like what it did. It seemed to flatten the sound.
At one point, we had the mic near the sitting position and we were getting a spike in the graph (I can't remember if it was a spike or a dip). It was weird. I had my laptop on the coffee table in front of me. I closed the laptop and the spike/dip went away. Pretty surprising because the mic was quite a bit higher than the laptop.
I'm sure I could benefit from room treatment, but I'd need to get someone knowledgeable to help me figure it out.
