I have compared Feet of Silence against Magix again and it confirms my findings.
Changed 3 Magix under computer case into 3 Feet of Silence
I started by watching a movie and I couldn't hear what they said anymore, many times I needed to scroll back in the movie and watch again. I never needed to do that with Magix.
There was fake whiteness and blackness and it gave me a headache. There was a lot of information missing in the music. Feet of Silence color the sound too much.
Put back 3 Magix under computer case
Everything was cleaner, smoother and heavier. There was more bass and low-level detail. Attack and decay was longer which made it sound fuller and less empty, this made the background appear less black but more clean and smooth. Transients were very hairy and there was more information everywhere. I can't listen to music without Magix under my computer.
Magix and Feet of Silence combination (I don't like it anymore)
Under my computer case I used to have 3 Feet of Silence, wooden board, and 3 Magix under the computer case. I removed the Feet and wooden board, and it sounded warmer but the low-level detail didn't change much, it might have got a little worse. When using only 3 Magix, it showed the coloration of the isolation feet below it.
Under my CD transport I used to have the same setup, 3 Feet + wooden board + 3 Magix + CD transport. I did the same as with the computer except I added one more Magix to make it 4 Magix. There was an improvement in low-level detail and fullness. 4 Magix have better performance than 3 Magix + 3 Feet of Silence. When combining 3 Magix and 3 Feet it just gives a combination of both sound signatures which makes it sound a little blacker, but it's fake blackness.
Like I found out before, 3 Magix isn't enough to properly isolate the component. When using 4 Magix it makes it sound heavier and fuller with more information in the music.
