When I set-up my M60s, I put a level on them and they looked real close. But looking at them now for several weeks, they just seemed to be leaning forward a little. Just for giggles I tried putting quarters under the front legs to angle them up, very slightly. I am astounded at the improvement of the highs. I felt my jaw drop, literally, several times while listening to my "new" speakers. What I thought were good speakers I now believe to be fantastic speakers! (Hmmm, you don't think I'm imagining it after investing all that money, do you? ;o) Seriously, try it. You might like it.
