Funny, I've been having the exact same issues with my Gallos lately. I used to have them on top of polycrystal amp stands, which only raised them about 3 or 4" higher than normal, and the sound was quite nice. I recently got a pair of the Bright Star Audio Isorock 3's, and replaced the amp stands with the Isorocks. Bass was definitely improved, and resonance was decreased, but they were just firing far too high above my listening position.
Part of the problem was the fact that the front spikes were on top of a persian rug (which sits on top of the wall-to-wall carpeting underneath), while the rear spikes were simply resting on the carpet. This created a roughly 1" difference that further rake the tweeters towards the heavens. So just two days ago I switched the front (large) spikes with the rear (short) spikes, and the tweeter/midrange is now much more directed towards my ears/listening position. I found that the sound opened up tremendously, though it does seem a little "upfront" now. I guess I'm going to have to continue experimenting.
