This is a NEW version of the GTX DR receptacle.
The basic body style and features are retained, and the conducting parts are made of pure copper. The difference for the NCF version is that it makes use of Furutech's Nano-technology to obtain better performance. NCF stands for Nano Conductor Formula. This is a NEW from Furutech pure copper AC receptacle like the original GTX, but here the part is manufactured with Furutech's NCF technology, which translates into even higher performance that is obvious to the listener at even the first blush of music.
