The problem speedbump, is that the controlled tests that have been done, and unfortunately there have not been a lot, are not very supportive of the theory there are easily noticeable differences between cables. My own work under contract in acoustics (speakers), showed we could swap cables and assuming level matching, differences were not noted. Customers (companies) would even bring in their latest toys and were disappointed to not reliably detect differences.
It may not be obvious across my posts, but I have said that I am not advocating the cheapest speaker cables, and that design does matter to a point and it takes a level of cost to get there, but that cost is really quite low, and does not require exotic wire, exotic materials, exotic connectors, etc. I truly believe that if silver was the color of copper and copper was the color of silver, people would claim copper sounded "brighter". The power of self suggestion is strong, people extend that claim to digital cables even though there is no correlation in properties. Ditto when people say a cable is "fast" or totally expanded my sound-stage. No, you probably just had dirty contacts or a loose connection but that is a harsh reality to accept. I could make a speaker cable that acted as a tone control, but it would be cheaper to use a few $ of passives. This is just speaker cables. When you get into interconnects, even though the signal levels are low, the relatively high output and input impedance compared to the cable properties means the cable, exception for noise rejection, has even less room for vendor / vendor differences though that does not stop them from making up reasons, all which sound good, and if true, would actually be pretty easy to measure, but they never do, just like they never do public controlled listening tests.
