And my point is that if the cables only present to you the illusion of "working" and you look no further, then you get stuck touting stuff that makes no sense, despite how real the situation seems to you. You're right that it is unrelated to my working for QSC. When I was a little kid used to think that magicians really could make people and inanimate objects float in defiance of gravity. Or make them vanish, despite the fact that matter cannot do such a thing. I learned since then that it is all illusion. That doesn't mean that I don't enjoy magic shows. Quite the opposite; seeing things that defy what my inner mind says is sensible is very entertaining. But I'm entertained, not fooled; I'm sure most who watch such shows are in the same boat, but there may be some true believers who think the illusions are real. The same thing goes with audio.
