Hi Jase, sorry I have defected to the other side.
Making cables lead to reading up on materials to use and the contradiction that different materials and means of construction end up all, according to the different makers, resulting in improvements.
Then further reading lead to a lot of blind tests. I found that with speakers blind tests tend to find differences, with bit rates, amps and CDPs there are differences, but not so easy to spot. But with cables, nothing. One was a very well run test of mains cables and people reported hearing a difference between the same cable! (Four cables were disguised with the same covering and two were the same).
There are very good placebo, psychoacoustic and justification of purchase reasons why cables can be perceived to sound different. But that is in the mind and not the cable.
