JPS vs Harmonic Technology IC cables

I want to know if anyone could compare the JPS Superconductor 3 vs. the Harmonic Technology Magic Ling 2.
I need a balanced IC between pre to power amplifier.
Please let me know your experiences in your systems.
I own a pair of Original Superconductor Speaker cables and was thinking about upgrading to the SC 3's. Does anybody have any experience with the two cables? Is it worth the hude increase in money to get a little more sonics, soundstage and clarity from buying the 3's? or Is the improvement in sound drasticaly better? Any help would be appriciated. Thanks, Erik
