Doubling a Set of Speaker Cables

While reading a "professional "review of the Daedalus Audio Ulysses Floorstanding Speaker, the reviewer is adamant about the improvement TWO sets of speaker cables connected to each speaker - regardless of the brand - makes.

This is something that crossed my mind long ago, prior to reading it now, but I’ve never realistically considered trying it nor have I ever come across this in a review. At face-value it seems to me this technique would do more harm than good. I’m wondering if there are any folks on the forum using this technique of two sets of cables (and as mentioned in the article this is irrespective of bi-amping or merely using a smaller gauge) and if so, can/do you vouch for any "improvement" one should expect.

Thanks.
