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?

Exhibit A

Excerpt from post on Steve Hoffman's website, circa 2004,

"....but two good guys I respect and know are George Cardas and Bill Low of Audioquest. Here is what Bill Low says about directionality:

"Directionality: All cables are directional, from hardware store electrical cable to the finest pure silver cables. All AudioQuest cables are marked for direction. With other cables it might be necessary to simply listen to the cables in one direction and then the other. The difference will be clear-in the correct direction the music is more relaxed, pleasant and believable. While cable directionality is not fully understood, it is clear that the molecular structure of drawn metal is not symmetrical, providing a physical explanation for the existence of directionality.""

Haven't you been paying attention. All cables. Hel-loo!

Measure the voltage at the transformer, Theoretically, their could be more than one voltage coming off of different windings. When you find what the 1200 VAC is dropped from by the transformer, multiply that by your rated watts. This answer is the amps, or current.

Fuse directionality is not something exclusive to only high-end fuses.  I found that even cheaper fuses have a preferred direction.  One way to find out is to look at the cap ends with a magnifying glass.  I found that the majority will have the power rating stamped on one end, and the other will usually have an assortment of symbols.  Yes, I found the OEM fuses even sound better in one direction, but not the same as the high-end ones. I have the Hi-Fi Supreme fuses.   Before plunging, I tried ceramic fuses of the same rating as the OEM. They sounded a bit smoother than the OEM. I simply diagrammed on a paper the direction using the cap's indicators. So far,  its been consistent for each fuse.  They key is, one direction will sound smoother in comparison.
