Well, I've heard the same rap from some regarding the Revel F-30, which sounds more like the Studio than you might imagine.
In my experience with Revel F-30's, I found set-up and room treatments to be even more critical than I had anticipated. Having treated my room properly and spent a LOT of time with set-up, I believe that the rap on the F-30's "brightness" may be due to folks failing to spend the many hours required for set-up.
I suspect the same holds true for the Studios.
Of course, just my opinion.
