Anyone use CD tweaks

I have just received a John Blue CD mat, which sits on top of the cd, without any preconceived expectations I noticed a signifant improvement, music sounds more distinguised, more detail, voices and wind instruments sound more natural. Overal the music sounds quieter (less background noise) and the music is more coherent, also less sibilance. Slightly better separation, it is as good as an expesive component upgrade in some regards and better because it eliminates the digital harshness of cds. Currently I am listening to Enya Watermark and am thoroughly enjoying the music, first impressions; the sound is more analogue, and more detailed in an unobstrusive way. It cost me US$40.00, and the material is very light, about 3 grams, so it should not affect the motor. I like it so much that I see it as essential to cd player use. Note the cd player sits on thick marble and I use small mahogany pucks, that only touch on the rubber part of my feet, not the aluminium, since that is the only way it is effective in my system.
