>>Simply_q: "Because I'm a human being. And like all other human beings, I'm just as susceptible to perceiving differences even when none exist in any actual physical sense."
Yup, pretty well documented that the human mind is real good at tricking its owner. No mystery at all. In fact, hearing a difference or not hearing a difference is pretty much what is supposed to happen, depending on your POV going in, whether there is a change or not.
>>tbg: "It always amazes me that people will not just try changing the direction and seeing if it makes a difference."
But people who say they hear a difference never confirm with a blind test. It's so easy to pull the fuse, toss it up in the air so you don't know which way it's facing, install and listen. Nobody seems to do this, and based on what we know about the way we perceive the world around us this amazes me.
You guys who say that those who have never tried do not know. I agree. But those of you who have tried and have heard do not know either...just my opinion.
