this round robin thing isn't working; i'm not comparing apples and apples. rather, i'm going to have to break it down into sets: some renders are "bright", others are "dark" and still others sound very compressed, almost "tinny". comparing them against each other isn't producing a total order. once i can break it into sets, i can compare apples and apples and then figure out which one i prefer as a base sound.
i can't isolate it as a single factor, either. that's why i couldn't get it right. if i take the model down on one and up on the other it will have a similar effect as if i do the opposite thing....
