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?

Actually they aren't. For the very reason that we observe in your results with the Red fuse. You cannot extrapolate or generalize your negative results to make some grand statement such as, "I tried the fuse and didn't hear anything, therefore it doesn't work." Capish? Now, if a lot of folks reported negative results I might be inclined to say, well, the preponderance of the evidence is starting to turn against the whole fuse and fuse directionality thing.  Alas, such is not the case.

Math drives all the science:

The audiophile fuses industry consists of 2 parts:

Part A: CONSUMER:
Portion will "hear" somethin' and be happy and portion won't and ask for refund. The "happy" portion will generate income.

PartB: LEGEND:
Purchase fuse from mouser.com or few stones from BB&B or piece of rubber from Home Depot, attach the story or legend or other terminological abomination to get as many as possible for "happy" portion to get maximum profit.

Everyone knows that selling 'air' is most profitable -- just need to know how piece of penny can bring hundreds of $$

Got that right czarivey.

This is just a shill fest, for fuse manufacturers or retailers, who are cleaning up on the gullible here, with "expectation bias" (love that saying Ralph you need to patent it) or the too lazy to return for a refund crew.

Dam wish I was devious enough to think it up. Maybe I can sell stick on resonant dots that have been cryo’ed!!!!!

Well I did try reversing directions and heard nothing so yes I can.

Don’t be scared......

You've done nothing but run your mouth.

Phew, what a discourse...
I have to say I am on the side of Oregonpapa, I have no electrical engineering experience either, but I have to say switching to the Hifi Tuning fuses made a difference to the sound my stereo produce. I only bought the fuses on the recommendation from SMc, and because the model was being discontinued and was on sale.
Would I have bought an $80-100 dollar fuse? No Way!
Since there are many variables that could have affected the sound (even the contacts of the fuse), I can't say for sure if it did something on its' own.
But, for my old ears, it did change something, mostly for the better.
As for reversing fuses, I would like to do this, but am now working more than playing, so it has to wait. Also, I don't think I can make a scientific/unbiased report when I have to power down the amp, replace the fuse and restart everything-every little change adds another unknown to the equation.
