How to reduce power supply noise.

I'd like to hear ideas on reducing the power supply noise
within a CD player. I have found AC conditioning and isolation to make staggering improvemnts to CD playback in my Spectal based system and would like to turn attention to internal improvements.
I noticed the Spectral Audio interview with Robert Harley
indicated much work has been done on their new reference CD player to reduce noise and interaction even further than in past models. Can we do anything with noise, crosstalk & interference in existing CD players?

I've defeated all of the grounding plugs in my power cables with great results.

I'm thinking of improvements inside the CD-DVD players.

What power supply modification? What is done? I think more attention should be on interference and "crosstalk" within the system-certainly the Spectral interview suggested as much. If that "magic"cloth? that was supposed to block RFI & EMI ?? worked I'd wrap everything in it. That cloth didn't seem to work from post here but I imagine there are other things to isolate various digital areas--but what are they? There must be an electronics whiz reading this....
