.[quote user="Keith McAlpine"] It'll never happen. Sadly What hi-fi, which is otherwise a very good and well written mag, is crammed full of audiophoolery and loaded with the ads of the suppliers of it. There have been 2 blind tests on mains leads on the web though, both of which show that mains leads don't make a difference. [/quote].
I have read the results of what I believe to be one of the tests that you mention, I don't agree that it necessarily shows that "mains leads don't make a difference ". In a blind test of unidentifiable mains leads carried out by some 20 odd people, some people preferred the sound of a standard mains cable, some preferred the sound of a branded one and some preferred the sound of a home made mains cable created by the test organiser. There was a second standard kettle lead included to see if anyone could identify the matching cable. Some identified the branded lead as being the same as the reference kettle lead, some the home made one and some actually got the kettle lead.
The results could be equated to those achieved by random guesswork, or it could be used as evidence as you state that "mains leads don't make a difference " or it could be used as evidence that different brands and models of hi-fi equipment react to cabling in different ways. However, I must query, why, if "mains leads don't make a difference" were any differences notiiced at all?, remember they didn't know what any of the cables had cost and therefore had no "audiophoolery" or psychotic self-delusion to fool them, this being the case, all the cables should have sounded the same
