I have the extreme phone standard mat and am looking to compare it/replace it with the herbies mat. I've enjoyed the sound of the extreme mat for the most part, but have not enjoyed the residue it's left on some of my records. (I figured out quickly enough to unclamp the record when done listening, as a few great records were stained with a dot pattern residue that's tough to come off. If you do this it doesn't leave the stain.) If you get a good buy on one it might be cool to audition it with another mat, etc. to see which you prefer.
