I compared several years ago the then "new" lighter, clear acrylic platter to the "then" all black acrylic platter. My take as memory serves me, is that that the black acrylic had better bass extension but was softer through the top end. The clear platter otoh, wasn't as extended in the lows as the black platter but had more perceived extension at the top, possibly because of the loss of bass.
