listening tests reveled larger differences in sound quality than could be explained by the differences in resistance. I mean, come on, guys, all audio circuits are AC. The resistance is not necessarily the reason why sound is different according to direction, it is evidence. Nevertheless, the lowest resistance direction of the fuse always correlates to best sound quality. See, that’s not so hard, is it?
OK, why don't you copy and paste and post here where it says there was any difference in the fuse direction?
