Yes...I am still here!
The actual gauge of the power cords, as with all of our cables are difficult to specify. Gauge standards are specific to wire based conductors. A pure Graphene conductor, for example, is about 1,000,000,000 gauge, but has lower resistance than a pure Silver wire the diameter of a basketball. We employ wire based backbones of 9 gauge, then add Carbon Fiber, Graphene, and Liquid Ceramic. What does this come out to in wire based terms? No idea. You cannot express composite conductors in terms that do not apply. There simply is no standard for composite conductors because everything is based on data used to computer model materials and cutting edge composites cannot be modeled because they are too radical and no data exists. This is why composites used in commercial airliners are 25 year old, because they can only model materials they have extensive history and data for. I model everything in my head and do no prototypes. The first Matrix cables produced were direct to production. I plugged them in and verified "Yep...that is what they are supposed to perform like." "Let's go..."
As some brilliant Audiophile once said "The proof is in the lisnin..."
