You will probably see less benefit since your speakers are tweeter-midrange where as the super 7 is mtm.
OK, here's my quick assessment --
I lifted the rear of my speakers about one-half inch and used Barbra Streisand's, "You Don't Bring Me Flowers" as my test track. Immediately, the imaging was improved, and when Neil Diamond cuts in, his voice is much deeper. No question about it. I said to myself, "that's gotta be all in my head." So I went back and forth. The difference was clear. Then I put on a few tracks that I'm more familiar with and can't say definitively it made a difference, but I didn't go back and forth with those songs. I heard enough to keep the rear of the speakers slightly elevated.
