Warm sounding power cord for for CD player to suppress digital glare on vocals.

I would look elsewhere in your system for a solution. 

Power cords are not tone controls.  And whatever effects they may have on tonality will be dependent on a complex and essentially unpredictable set of interactions between the technical characteristics of the particular cord, the design and technical characteristics of the specific component that is being powered, the characteristics of the incoming AC, whatever ground loop conditions may exist between the component it is powering and the other component(s) it is connected to, how that cord is physically routed in relation to the physical routing of other cables and cords in the system, the sensitivity of other components in the system to the specific characteristics of whatever digital noise may be coupled into the AC wiring from that specific component, etc. etc.

I suspect that Peter was thinking along the same lines when he made his joking suggestion :-)

IMO, FWIW.  Regards,

The best way IMO is with the use of warm sounding interconnect cables from CD player to pre-amp.

almarg is right about power cords.

The warmest low priced interconnect I know of is Cardas Cross.

Try that for a start.

Why three identical posts?

I agree with Al, and some system details would help. Perhaps time to upgrade your digital rig? Or another part of your system? Cables should be the icing and not the cake.

Warm cables will just make the glare (and everthing else) warmer. 

Al is correct, and I never doubt Peter
