Determining current flow to install "audiophile" fuses.

I would bet that if you snuck into a "fuse-centric" audiophile's listening room and reversed all the fuses exactly nobody would know…the fun part starts when years later you tell 'em about it. 

I can rest my case…maybe.

There is no explanation needed when the "audio magic" light is lit, as geoffkait (and other supposed golden eared magicians) firmly believes the skeptics put up with "bad sound" as they dare to not consume the Kool Aid hard sold to the easily duped…how bad does atmasphere's rig sound? Must not be too good if he's a "directionality denier" which is ironic as he seems to know more about this stuff than most of us.

You really can't pose any argument or meaningful discussion with subjective opinion regarding magic fuses or any other technically questionable tweak…if somebody "feels" their hifi has an improved soundstage, instrument tonal quality, or any other improvement from a premium FUSE (!), it has to stand…among those who have had a suspicious relationship with SR fuses (seriously overblown prattle that should raise eyebrows implying a commercial connection with the manufacturer) the arguments regarding the cheapness of the product relative to other tweaks ("the BMW cost you 50 grand, why not spend $300 on valve stem caps?") is lame on it's surface. By asking potential buyers to spend hundreds or many hundreds of dollars on something costing 20 times what it should (relative to other, non precious fuses) since "you can return the item before 30 days," plays to the fact that most simply won't bother to return these things or will keep turning them around to test directionality or adding more break-in time because they really really want them to work. This desire to hear things that might not exist because you paid dearly for it, and ego driven desire to not be left out of some "extra sensitive hearing" club drive most audio silliness and distract from actually valid or perhaps useful information that keeps the hobby rolling along.

I recently removed my power amp fuse (cleaned the contact area) and when I put it back I forgot which direction it had been in, thus ruining my shot at trying to hear a difference…I will not remove it again soon as I don't like to move my 50 lb tube amp around…I just have to sit there and listen and wonder…are the electrons moving properly? Is the recent rabid promotion of SR fuses reasonable and/or logical? They are simply neither and play like they're commercially funded. 30 day refund or not, the heavy handed hype is simply too damn off-putting to get on board…illogical magical hifi tweaks come and go, and most seem like a sadly lame waste of time and (some people's) money.

Cleaning the fuse contacts might make your fuse do its job a little better, and the otherwise magical effect a 4000% profit margin tiny wire (an SR black fuse for example) is certainly El Placebo a Mundo. Putting a $112 sandwich on your gear would likely do the same, but at least later you can eat the sandwich.

Note the quotation marks around "many." How telling. There isn't even any actual evidence that SR "quantum tunnels" (man…nice choice of terms there SR, as not only does it not make sense, it sounds great!) anything with their silly claims of having their Chinese factory treat this tiny wire with "2,000,000 volts" of unobtainable juice, any rational explanation of why they would do this, or why the ratings on the fuses is apparently dangerously incorrect ("buy the higher rating just to be sure it works" has actually been suggested by the promoters of what is essentially a safety device). People's imagined claims that these fuses do something and then do it better reversed should be regarded as the weirdly imagined nonsense that it is, and the rabid promotion of these products by a few zealots is a shameful fraud. Buy a reliable Littlefuse and save the 100 bucks for some sandwiches…you'll feel like everything sounds much better...
