The first test I recommend when testing a new cable type, is to wire both speakers to one amp channel and first verify that all image is dead center. If it is not, stop, do not proceed.
If perfect, then wire one speaker with the new cable. If all the image remains perfectly centered, stop. The cable made zero difference with these speakers.
If some of the image content shifts to either side, or becomes a non sharp centered image, then you have spotted a difference in response.
If that occurs, reverse the cables and re-try. If the change follows the wire, you can decide if you like what the new cables do, or not. If the change does not, you are chasing a perception ghost.
