    and when you've finished reading that, the next article on the list is "Why do fish smell fishy"

    Hmmm, notably they don't make mention of whether statistically significant results were obtained.

    Regards,

    The "paper" in question is an explanation on Tag McLaren's website explaining why Tag McLaren thinks you should buy a particular type of cable that is made by Tag McLaren. That doesn't necessarily invalidate the results, but it is reasonable to consider the issue of impartiality (or the possible lack of it).

    I am rather troubled by this bit:

    That sounds suspiciously as though, if the listeners report a difference, the engineers will accept that reported difference as absolute evidence of a change in the signal-bearing properties of the cable even if there is no measurable electrical difference to the signal - which is absurd.

    We also, of course, don't know anything about the rigour of the alleged "blind" conditions. Interestingly it is only the New Scientist summary that refers to "double blind" and not the main article. Either way, it's painfully obvious that this hasn't gone through anything remotely resembling the peer review process that an article would have to go through before being published by a scientific journal.

    Even some of the actual science seems a bit odd. I am troubled, for instance, by the idea that it takes several hours for dielectric molecules to align themselves correctly when you reverse the cable. Most solid dielectrics don't work by having the molecules in them change alignment. They're polymers - the molecules are too big to start swinging around like that, and aren't naturally polar in the first place. The dielectric response happens because of a slight change in the distribution of the electron clouds within each molecule, and that certainly won't take hours to happen....

    Not being of a scientific bent I am now wondering whether I should disregard the reasons why fish smell fishy too.

    A better thing to consider is whether, if someone shows you a motorcycle and tells you that, in his opinion, it smells fishy, would you automatically assume on the basis of this that it must actually be a fish rather than a motorcycle?

    If he had the title 'Dr' that would be even better!

    IMO if somebody wants to waste their money on cable blessed by a blind one legged albino pygmy it's their own lookout.

    sorry to go off topic further..... but did you know that if you use biodiesel (which often originates from scrap chippie oil) your exhaust will smell like fish and chips?

    As far as the thread...... anything is possible in science with the right motivation, scientific test doesnt necessarily garantee that the test was done correctly

    Is it just me, or is this thread getting ever so slightly off topic...?

    Just a tad! :D

    did one or two members not attempt some fairly scientific comparisons of cables? I'll have to go and have a dig but i could swear i recall seeing something perhaps a year ago
