How high is your soundstage?

I have been having a lot of trouble getting my soundstage to sound the way I like it. Almost all of the systems I have heard generates a soundstage that is 1-5ft above the speaker itself. I really like this as it helps to make the speakers disappear. Sound seems to come from behind and to the sides of the speakers. Everytime I hear my friend's setup, I go home frustrated. In my setup, the soundstage is right at the tweeter level. To me, too much music is coming directly from the speakers. I do not hear anything behind or to the sides of speakers. In other words, my soundstage is narrow and shallow! I have tried a lot of different speaker/sitting positions to no avail. Nothhing I do raises the soundstage. I am pretty sure its my room.

So out of curiosity, I would like to know how high is your soundstage? Is it at tweeter height or above? If above, how much above?
