While my primary reaction is against the dim, mediocre ponderance of relative importance of anything audio, especially variables that don't compete against each other, I also automatically thought about the slew of confounds that were dismissed in Stehno's bold conclusion based on a single experience. Then I think about how one can compare the degree of room goodness with the degree of speaker placement goodness and how one can compare rooms when "optimal" placement was not achieved in one, which got me to my own experience. A half-dozen rooms and god knows how many spots for the Revelations, I have to conclude the differences between rooms were not fully made up for by placement and vice versa. With the best place I could find in each room, which is easy because my speakers are very predictable in placement, the better room sounded better.
Without being concerned about the problems in Stehno's comparison, his conclusion could be reversed, or could be called a tie between room and placement by using a different logic, a logic that includes the amount of effort he put in to placement.
