There have been some interesting advancements in speaker cable engineering. I balk at spending that kind of money too but there is a free trial available.I will go the other direction now and say that testing $2,000 speaker cables is equally not worth the effort. Again, I am an engineer. Go get a job at any aerospace company and suggest any improvement to their planes. Get a job at a computer company and suggest a (technological) improvement to their computer. Unless you bring a good reason "why" they are not going to try your idea. I haven't heard a compelling argument for speaker cables beyond "reasonable diameter, decent materials." So I feel no duty to test them.
Check out the design theory.
