@stereo5I agree, sometimes things do not add up. It just reinforces the point that your room is the single biggest factor sometimes.
I had a pair of 7" Scanspeak revelators with an aircirc tweeter and high end crossover--the VR-33's gave overall a better performance, including the bass. So go figure. I also owned Magnepan 1.7's and enjoyed them very much. But they would never perform close to the front wall like the 33's do.
@uberwaltz I did own a pair of Triangles years ago. I liked them. If memory serves me, I would say from the midrange up the two are not too dissimilar. I think the 33's may be a bit more organic with a sweeter high end however.
