Power cord replacement suggestions

Like everything else in this hobby it's an experiment.  I'd try some from a brand (or two or three) that sells direct with a good trial period.  Triode Wire Labs gets consistently good reviews and one I'd definitely try.  Best of luck. 

I second those who say you must experiment; and williwonka has basically 
explained why. BTW there's nothing "fanatical" about better power cords-except the pursuit of ultimate quality by those attempting to provide the best, like MIT Cable for example .If you have 
a system capable of revealing the differences,listen to types of music where increased resolution, refinement and dynamics are important to you,  and if you have a suitable listening environment then -if you experiment- voila !  you will understand. Elementary my dear Watson. 

I also suggest beginning with the source components. Stiffening the smaller power supplies seems to yield the greatest improvements.

Ordered a graphehe cord for cdp.  Preamp cord is next, iffin' i like it.

droleg,

For your guidance, quote taken from your manual.  (I currently own the C-X7eMP)

"...Ayre C-5xeMP may be plugged directly into an
unswitched wall outlet. Although proprietary RFI
(radio-frequency interference) filtering is built into
the disc player, in some situations an AC power-line
filter (such as those offered by Ayre) may provide
additional sonic benefits..."

Goor luck with your new power cable!
