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?

I really didn't want to participate in this thread but it occurred to me that I had to replace more than a few fuses in my Marantz Reference components (about 6 or 7) and the odds that I put them in correctly, all oriented in the right manner, the first time around, are nigh well near impossible.
I learned my lesson and always ask designers for the correct direction.   

Once a new fuse sounded better installed in wrong direction.  System sounds good but seems out of phase.  Friends notice the same and new fuse was never brought up or crossed my mind .    Then corresponded with several owners of the same component and they all heard same with fuse in wrong direction.    I reversed direction, still sounds tight but after more hours, it opened up and sounded right again.

This wasn't the case in all components but usually with higher quality components.

You had to ask.

As they would never put it in writing, as then that could very well be liable.

You had to ask.
yes to save time.   I'll eventually find a prefer direction if it makes a difference in a component.

As they would never put it in writing, as then that could very well be liable.

After market fuses cover a wide range of products so totally understandable.   Some owner manuals warn against after market power cords too,

I've been using after market fuses forever and can hear fuse direction in some components.   I'm not interested in a debate ... over and out!

I'm not debating after market fuses, power cords or anything if they are used as such and are to the standards.

What I queried was that you had to "ask" the manufacturer, and that it was not stated in any doc or on their website about the fuses being directional, as this could be liable.

And I still challenge any member to show a publicly seen doc that a manufacturers fuse is directional.
