Try it on your source instead, weird as it seems when I put some aftermarket powercord on my ARC SP-16 it sounds bright if the source wasn't treated as well. So start at your source, of course IMHO.
I tried Cardas Quadlink 5c power cord and it had rolled off highs, not bright, it was dark and euphonic.
