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

Well now that I know you have such a fine CD player, the glare you speak of is coming from the mastering of the CDs, and not player related. 
I can understand your search for a PC now, since I have noticed how they can have an effect on certain frequencies when used in a digital chain. It’s a lot of trial and error as you know.

Thanks lowrider. (Of course, I was trying here to learn from someone else's trial and error who was kind enough to let me know what they discovered.) Again, thanks to all the commenters.

Listening to the White Album now...good luck trying to tame bad recordings like that. Some Mullard tube saturation in the preamp was the only thing that made things like that more tolerable for me. 

The Beatles seemed to have wanted their recordings to sound like that. Imagine hearing hearing that stuff on the Altec monitors at EMI....

" I listen to older CDs (and the Bealtes) and there is definitely some glare in vocals on many of these recordings "

...:Powercord??
Is that too much of a whole bunch to ask just from powercord? 
How powercord even $$$$ can fix THAT?
I've just imagined anyone casual reading that LOL.

For older CDs all you need is tube buffer such as Musical Fidelity that will cost substantially lower than so mentioned powercord.

Any pc from Cardas.
