yeah, the total cable is 16awg, but it uses 2 x 19awg conductors for each leg. I was going to mention that the Audioquest power cord is quite stiff. If you want to completely strip the outer cover and then just use the individually insulated conductors, you're better off just getting straight chassis wire. Look at the Neotech 20awg Teflon OCC:

Or, if you want even better wire, try the Unicrystal OCC hookup wire from VH Audio:

Then just use as many conductors for + / ground that you need. Every time you double a wire, you increase the awg by 3. For example, 2 x 20awg = 17awg. 3 x 20awg would be something like 15.5awg. You can twist the wires or braid, then cover with heatshrink and/or techflex. This would be more flexible than the Audioquest NRG cable.
