What stilloints dont do is alter the sound characteristic.
If you try other solutions - I have not tried them all but they alter the sound somewhat - either toning it down or softening it which can still be beneficial as it can give the sound more calrity and definitiion - pieces of the music are more distinct in their own space and have more space around them - that is improving clarity to me.
Where as the stillpoints - do this but dont change the tonal character at all - they dont smooth the music - they actually do the opposite which is really surprising the music has more verve not sure thats the right word.
Each element of the music not only has more 2D space it also has more 3D space for example bass notes stand right out where before they were just blended in with the sound.
We used Paulo Nuttini - Iron Sky as a test song as it starts with pure bass line then stuff adds to the music. With the stillpoints the bass came forward in the space and was much clearer, fuller and defined. That was enough to hook me but there were other benefits also in treble and vocal the same
With the vocal in that song which is husky as you like with the Stillpoints the vocal had more character and you could hear much clearer the way Paulo was singing kind of from the throat - again this improved clarity to me. The vocal again stood out more as well from the other elements in the music - for me that imrpoved clarity.
Why is the happening - vibration gets added to the sound the same as a reflections do acoustically in a room. the more you remove the more clarity you get, especially for sensitive spacial cues that can give a sound a true 3D character.
I have only heard a truely 3D sound once - and that was a top end system not surpisingly on a full Stillpoints setup of about £15k
