Do you "re-fuse?" (my 32nd most cerebral pun of the decade). Follow the rubber line. Now I feel I have to take every piece of my gear apart and see if the wires are "direction appropriate"...would an electron microscope be useful in detecting the optimal wire grain orientation direction? Damn...this is gonna take forever....
Fuses that matter.
I have tried six different fuses, including some that were claimed to not be directional. I have long used the IsoClean fuses as the best I have heard. No longer! I just got two 10 amp slow-blows WiFi Tuning Supreme fuses that really cost too much but do make a major difference in my sound. I still don't understand how a fuse or its direction can alter sound reproduction for the better, but they do and the Supreme is indeed! I hear more detail in the recordings giving me a more holographic image. I also hear more of the top and bottom ends. If only you could buy them for a couple of bucks each.
