Your broad pronouncements of what others should do seem presumptuous to me. Rather than living in the world of "shoulds", I would recommend you try the realm of "ears on" experience and try some cables to hear the difference (or not) for yourself. Experience trumps "theory", IME.
I'm an engineer, and I would have sworn that all of this cable nonsense just shouldn't, just couldn't make a difference. But sometimes when I have tried them there was absolutely no doubting the differences and the musical improvements in my system. Reluctantly, I have put some serious money into wire, and my ears are glad I did. That's my experience. You just cannot beat trying something yourself, rather than simply accepting conventional wisdom.
