Consider the validity of an argument that has to resort to condescention... "Well, if you can't hear a difference, your ears are ignorant." ...to make a point.
If cables made a real difference, there wouldn't be an argument. There would be clear and convincing evidence. The only evidence I see in the arguments made in the defense of high end cables is that they seem to function as an ego boost of some sort. That's fine for some folks, but my self worth is invested in things other than stereo systems, cars and designer clothing.
Relax. Nobody is atacking you.
Your quest for Ultimate Fidelity is possibly a lot easier than for those who do hear a difference.
