Mycrafts don't be so ignorant, Gee I guess the multi million dollar marketing and sales of high end cables is just a farce right??
If you go to the respective cable web sites you shall see what is the difference in each cable. You will never see a high end installer or competator using zip cord and manufacturers interconnects on there systems. Have you heard of words like signal loss, RF noise and digital Jitter- apparently not.
You can do and say what you want and so shall I. I can definatively tell you that every time I upgraded from stock crap it improved the dynamics of the system, maybe you need to have the wax cleaned out of your ears mycraft.
