Otherwise, he'd tell you that a heavy damping material was what you need. Of course, if it takes out the harshness, since music is sometimes harsh, then naturally you need a new moving-coil to put it back in. Unfortunately, he's actually a little behind the times. The most recent research has conclusively demonstrated that the best platter-mat material is a foot-diameter sheet of diamond. You see, the diamond has the same resonant frequency as the stylus, and .... -- Jim Crandell, C. S. Dept., The University of Texas at Austin {ihnp4,seismo,ctvax}!ut-sally!crandell
