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?

FWIW we have gotten good reports on some of the boutique fuses from our customers. No-one has ever asked about directionality, and all our fuse positions are AC circuits. Since AC has to go in both directions, it follows that directionality is impossible. In fact, if the fuse were in any way directional, it would heat up and fail almost instantly!

IOW the directionality thing is a myth.
