I tried several before but nothing really made consistent noticeable improvement.........until I used Herbies CD Mat.
This is thin rubber mat similar to surgical glove material that naturally sticks to CD surface, no slippage like other mats. Seems to actually improve sound slightly on a consistent basis, very reasonable price. I have used with several front drawer load Musical Fidelity CDPs.
