The study I'm referring to is I think available on Hifi Tuning's website. If it's not, it's easily found as I chanced on it while looking up Silver Star fuses, which I ended up buying.
I'm not writing a paper on fuses here, I mentionned it trying to be unbiased about the subject. The study did mention a slight difference in measurement depending on polarity but I don't remember what these measurements where.
I totally accept the existence this difference. I'm saying there's absolutely no way one can hear it. And I'll say it until proven wrong by proper demonstration.
As you say, I might not be able to hear the change a fuse produces. I'm totally fine with that and I accept the possibility. That's why I've asked other to try. But not to try the way they like. Only within the confine of a blind test.
All I can say about my hearing is that when I added Rollerblocks2+ under my cd player last week, I heard a very significant and positive difference. I'm suspecting if I can hear little balls under a component I would hear a fuse. Maybe I'm wrong.
So once more, I'll ask the question: did you validate your conclusions with a proper blind test? Within the context of this blind test, could you reliably identify an audiophile fuse? Could you reliably identify its polarity?
As far as I'm concerned, audiophile fuses are up there with voodoo-ish solutions, only topped by Acoustic Systems resonators, which are celebrated all over the net by reviewers.
None of them having done a blind test, at least not one they mention.

regarding measurements - unclestu 14:33:18 04/21/10 (0)
In the world of smells, the best "noses" can detect what amounts to a few parts per trillion, as determined by spectrographic analysis of a cubic volume of air. Usually human perception of scents is considered one of the weakest of the human senses. What would parts per trillion translate in terms of sound to such things as distortion, etc.?

So now, we come to that "slight" difference in measurement. I doubt if that magazine uses something like the best Rhode and Swartz test units. Their real time analyzer costs over 6 digits and there are maybe 6 to 8 units in existence worldwide ( US bureau of standards, NASA, and the military have one apiece). So in terms of the parts per trillion that a human, a bit skilled, nose can detect,l what equivalent is that "slight" difference. Accuracy to 6 decimal places is only to the millionth degree.

When you say "...did you validate your conclusion with a proper blind test" and "voodoo-ish solutions" is where I sharply disagree. It is fine, of course, for you to impose a blind test on yourself (incidentally, did you on the Rollerblocks, which I found of no value?), but you have no right to impose it on others. No one has designated you as the scam police.

I have tried many tweaks that I thought had minor benefit, some that do major harm, and some that I would not do without. But I am not to judge what others prefer. Otherwise I would say that 99 percent are using awful speakers or cannot hear.

  Hi,
  You misunderstand my point here.
  I'm not the scam police. I don't even care if people spend millions on audiophile fuses, it's good for the economy.
  But this forum is a place for sharing, and I thought it would be useful for people to submit themselves to a simple test. Your resistance to it, and other's, actually speaks volume. What's the risk, what's the downside of a blind test? We would all learn from it. Either I'm wrong or you are. I've said and repeated it: if I'm wrong, then fine.
  Re. the Rollerblocks, you're totally right, I make no exception and I should test myself. Except it's much more of a hassle, I would need somebody to help me and it would be time-consuming.
  The beauty with this fuse business is that it can be done on one's own. I see NO REASON not to do it, really.
  Now if you can't be bothered, if you're looking for peace of mind by having these fuses in, then it's totally fine.
  But saying "I hear a difference" doesn't mean anything if you haven't placed a bit more of a challenge on yourself.
