My 2 cents: if the selling point of this cable is the Litz braiding as the review seems to imply -- it might as well have none.
This helps for the skin effect, which is non-existent as 60Hz. But worse, the power cable only carries one frequency, so it makes a Litz braiding quite useless. The idea is, when you send a multiplexed signal (that is, many frequencies together), the skin effect makes the resistance of the cable be larger for higher frequencies. In effect, it tones down the higher frequency (think of it as a low pass filter). Now if you have 1 frequency, it seriously does not matter, just increase the power at the input if you can.
To rephrase, the review is correct when saying that Litz increases the bandwith. But here, we have a signal (power signal) with a bandwith of zero!
So why would one want this cable -- that is, for rational reasons?
