Determining current flow to install "audiophile" fuses.


There are 4 fuses in my Odyssey Stratos amp. I recently returned some AMR fuses because they rolled off the highs and lows a little too much for me. Mids were excellent though. Anyway, I'm getting ready to try the Hi-Fi Tuning Classic Gold fuses, as they are on clearance now for $10/ea. Are they any good? However, I have read that they are a directional fuse? Can anyone confirm this? If that is the case, does anyone know the current flow for the Odyssey Stratos? Or, does anyone know how figure out current flow by opening up the top and looking at the circuitry?

To Atmosphere:

As a long time manufacturer of amplifiers and pre- amplifiers I hope you will share in detail the feedback your customers have conveyed to you concerning which fuses improved the sound and which did not. 

I think this information would be especially useful to the OTL community to which you and I belong. My amp is an Eddie Current Zana Deux - tube based , as are your OTL products. Your providing this information does not constitute a manufacturer's endorsement.

Your right Al I sped red it, and my apologies to mlsstl. The voodooist's know it's aimed at them.

Well, I was the first to answer the OP and said I couldn't think of why a fuse could be directional.
Since then, I called McCormack (I own a DNA-1)and spoke at length with Pat, who said that I should try the fuses in both directions and see if there is a difference. (He did think there is a difference)..
I bought the last few Hifi Tuning Star Sapphires still available for the Power Mains.
To me, yes, there was a difference in sound, a significant change, mostly for the better.
So, after a few days, I will try reversing the fuse and will post my observations.
No, it won't be a scientific test, but I consider my audio system a pleasure/hobby.- Though it would be nice if there were a scientific explanation. 
My only gripe is that many of these companies are upgrading their fuses, AND then increasing prices to somewhat unreasonable amounts.-Perhaps that should go on another thread....
Excerpt from the introduction of Zen and the Art of Debunkery:

"As the millennium turns, science seems in many ways to be treading the weary path of the religions it presumed to replace. Where free, dispassionate inquiry once reigned, emotions now run high in the defense of a fundamentalized "scientific truth." As anomalies mount up beneath a sea of denial, defenders of the Faith and the Kingdom cling with increasing self-righteousness to the hull of a sinking paradigm. Faced with provocative evidence of things undreamt of in their philosophy, many otherwise mature scientists revert to a kind of skeptical infantilism characterized by blind faith in the absoluteness of the familiar. Small wonder, then, that so many promising fields of inquiry remain shrouded in superstition, ignorance, denial, disinformation, taboo . . . and debunkery.

• Put on the right face. Cultivate a condescending air certifying that your personal opinions are backed by the full faith and credit of God. Adopting a disdainful, upper-class manner is optional but highly recommended.

• Employ vague, subjective, dismissive terms such as "ridiculous," "trivial," "crackpot," or "bunk," in a manner that purports to carry the full force of scientific authority.

• Keep your arguments as abstract and theoretical as possible. This will send the message that accepted theory overrides any actual evidence that might challenge it -- and that therefore no such evidence is worth examining.

• By every indirect means at your disposal imply that science is powerless to police itself against fraud and misperception, and that only self-appointed vigilantism can save it from itself.

• Portray science not as an open-ended process of discovery but as a pre-emptive holy war against invading hordes of quackery-spouting infidels. Since in war the ends justify the means, you may fudge, stretch or violate the scientific method, or even omit it entirely, in the name of defending it.

• Reinforce the popular fiction that our scientific knowledge is complete and finished. Do this by asserting that "if such-and-such discovery were legitimate, then surely we would already know about it!"

• Deny the possibility of phenomena for which no plausible explanations have been advanced. Ignore such contrary examples as the existence of disease prior to the discovery of microbes, the sun's copious production of energy long before the discovery of nuclear fusion, and the stubborn persistence of gravity despite our stubborn ignorance of its inner workings."
