Yes, they perform the same. The first one is made at the Mogami factory and sold at retail stores. The second cable is from a company that buys spools of raw Mogami cable and terminates them with connectors and sells them over the internet. WBC does professional quality work, I have bought their finished XLR cables. There is nothing wrong with either buying method, they both work. The only difference is that the factory made comes with a lifetime warranty, the WBC a 10 year warranty. Hardly anything worth being concerned about.
