Cleaning up AC power definitely helped my problems in that regard. The JPS Digital AC cord is one popluar remedy here on the 'Gon, in the filtered AC cord area. An AC power input balancing transformer or other line conditioning has reportedly been successfully implemented (although I did not require them - just the filtered cord).
RF stoppers on the output interconnects may be a useful troubleshooting tool, but should not be left installed permanently (they excessively round off the HF's & transients). Ferrite filtering ring &/or Highwire Powerwrap on the AC cord may do well for you however.
I also realized improvement with Nordost Pulsar Points placed in between the CDP's baseplate & whatever type of shelf that you're using (if any). In my case that would be a Zoethecus Z-Slab, (Mapleshade or Black Diamond are some other popular shelf options). But you'll need to experiment in order to to determine what works best with your own unique combination of player, cabling, & equipment rack in any case.
