What I can't figure out... And I'm not pointing a figure at any one person... Whenever a 'contentious' thread is started like this, why can’t the non-believers resist hitting the reply button? Replies which basically consist of “don’t waste your money it’s all a load of codswallop” don’t help the o/p do they? The o/p’s bound to know such questions polarise opinion, but surely he must hope that he’ll only get responses from people who share his views? Instead he has to scroll through irrelevant posts to find replies from people who are genuinely trying to answer his question. Is it too hard to look at a thread and say to yourself, “well I’ve nothing constructive to add because personally I think it’s a load of lobbox, so I won’t”? The same thing seems to happen on here with monotonous regularity, sad to say
Major,
Everyone is clearly free to believe what they will, however I do think it is appropriate to question the beliefs of posters in a public forum like this, particularly when the beliefs fly in the face of generally accepted engineering principles. Unchallenged, and repeated often enough, hearsay becomes accepted as fact.
While pretty much anything is possible, it is very unlikley that a short length of mains cable will make any audible difference to the sound of a hifi setup. It certainly won't change the tonal balance, at the very most, and in the case of a poorly designed amplifier (with inadequate input mains filtering and in the presence of significant RFI) it just may reduce the noise floor.
There are no independent studies on the web that I can find that give credence to the claims that mains cables can make an audible difference. Many manufacturers do however make heroic claims for their product, some of which get challenged. Most notable was Russ Andrews:

If any forum member can post a link to an independent study that shows that mains cables do indeed make a difference, I think that would help move the discussion forward.
