Sabai, I know of several very good sounding speaker wires that cost $25,045. $22,000 dollars and $35,000. Two of the three have substantial shielding, much vibration control, and sophisticated metallurgy. One is a minimalist approach. This is basically an artistic approach to cabling, much like Gallup and other noted pollsters use. In contrast, academic survey researchers use careful random samples where we can be pretty confident that the sample is close to what the population is. High Fidelity, by contrast, is more scientific in maximizing the influence of magnets.
I seriously doubt that a DIY guy can challenge these efforts. Most of the manufacturers have evolved from DIYers. I have been through perhaps as many as fifty different cables, including some that I made myself out of speaker wires made into power cords and welding cables that I made into speaker wires that looked and sounded the same as a Minnesota manufacturer's early speaker wires.
Maybe mankind cannot make the "perfect" interconnect, power cord, or speaker wire, and maybe we never will be able to do so, but trial and error are what we now must rely on.
