Lots of people here know more about cables than I do so maybe greater wisdom will chime in. But yes, I think certain cable brands- like Cardis- are generally thought to deliver a "warmer" sound, so might pair well with speakers that are on the bright side. I think Focal perfectly illustrates how subjective all this is - Focals are very detailed and transparent. Some folks find them bright but obviously many more love the sound-one of the most popular brands in the marketplace.
I think you are right to give all your new equipment time to settle in before making another move.
Good luck!
