The Mystic Mat on my Kuzma had the effect of tightening images, ie in the lower mid/bass, there was better focus. This was the most obvious difference. Of course once you listen more, then you will notice that the background gets quieter, thus dynamics are enhanced. Even cymbals have greater clarity. Other mats just don't compare with this.
It does require the use of a clamp, so your spindle should be long enough to accomodate this.
