The posts here certainly aren't going to tell the whole story about blind tests; whole books have been written about them and they have long ago been discounted by the mainstream scientific community as a reliable measure of whether a perception is valid or not. Why don't flat earth society members start a "power cords don't work" thread and leave the rest of us alone? The answer is pretty clear.
The fact that they can't be satisfied with merely posting their own listening experiences ( which they have yet to do here, btw) says quite a bit. A very wise engineer once said, "If you haven't listened yourself, you don't HAVE an opinion." The best and most civil advice is to listen for yourself. Borrow a cord and it won't cost you a dime. It'd be great if the debate were to end with that but and we could return to sharing what we love, but this will probably degenerate into the usual, pointless p***ing match. Is it any wonder the hobby is shrinking?
