I don't know but they are brighter and "righter" if you will. I had other high dollar cables from Nordost,Kimber(KCTG),AQ Jag,MIT and Cardas. The HF on the Antis in my setup was more present,extended and the cleanest I tried. They livened up my warm sound to here it is more balanced. The connectors on them are modest at best as well compared to nice WBT's. I don't know that the dielectric is that high but if you say so. I'd like to try Mapleshade ribbon in plastic. Thanks for the post.
