Talking about fuse directionality, Hifi Tuning has a logo with a diode symbol in it. At some point people began believing this diode-arrow was the factory tested recommended direction of the fuse. But it was not, it is just a logo.
Personally I do hear a difference in a direction, but I also believe it diminishes after some power on.
