I usually use Mogami too, but I lashed out on some of this:
Of course you need to dress the ends yourself… exactly the same as using Mogami.
I think that the Benchmark has SpeakOn connectors??
If so Neutrik SpeakOn is easy, and their stuff is nice to work with.
I am not sure that the cotton is better than Mogami, but it gives you some other option to consider.
I went for cotton as there is no teflon and a lower dielectric constant than the plastic insulation. So I considered it like a po-man’s battery biased AQ speaker cable… Just rather than a battery, I am using a dielectric with does not polarise.
