FX isn't the one to compare to, it's Superconductor bi-wire that is the contender, and it is much more neutral and forgiving with whatever kind of equipment you are using. It won't be as forgiving if you are using Cardas interconnects but that is because it reveals the faults of the IC's, not that there is a problem with the speaker wire. JPS is neutral which can reveal characteristics of the Cardas, use JPS Superconductor 2 interconnects and it will prove that out very well.
