Stop with your ranting! I KNOW that cables make a difference for me because me and my friend/roomate have done extensive testing, where we've had no idea which cable we were going to hear, and there was absolutely no order at all at which the cables changed. I could simply tell a big difference between a high-end cable and a cheap one. So could my roomate. I don't care what gibberish you throw at us - I know that it works because I can, under controlled testing, under scientific method, easily distinguish between two different cables.
Do I think "magic pebbles" work? No, but they have a very specific market of rich, gullible idiots. There are plenty of those out there. The people making that stuff are business men, and not audiophiles.
Everything you do to your audio system makes a change of some sort. With stupid "magic pebbles", the change is indestinguishable. With cables, however, it's quite obvious to me. Maybe you're losing your hearing. Maybe you've simply never performed such tests before. Maybe you have tin ears. I don't know the reason, but something tells me you've never tried out of your ignorance... and that's just what it is. Ignorance.
I give EVERYTHING one chance, at the very least. I make decisions on my own. Scientists do the same thing. The only things that are proven true are those that can be proven with mathematics, where an if-then statement can be converted into a 1=1 mathematic equation.
Use common sense here. In this discussion, you have no credible evidence for your theory. Some people in threads like this have given these claims about how they can tell the differences with ease. I'm among them. I, like you, thought that cables didn't make a difference -- then I actually tested myself. And... I know now that, after the extensive, unpredictable, and controlled testing, that I can conclude with a theory: Cables can make an effective, audible impact on your stereo system's sound quality.
However, you do not offer any kind of evidence - not even subjective evidence. Again, use common sense. You have nothing over others who think differently than you. You claim to have a lot of knowledge in the audio engineering field, but you haven't used your knowledge in one clear, identifiable, or intelligent way yet. Get going.
