"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."
