Determining current flow to install "audiophile" fuses.

I don't think there is any fuse that doesn't have a direction that is best. Even when Syn. Res. zapped their fuses both directions on direction always sounded best. Why if there are real scientist here can they not explain why. The nonsense that it is AC current going through them is obviously wrong. 

Stop being engineers, real scientists would be finding out why there is a direction. If you don't bother, I will not be surprised, but I really don't care. It is everyone loss if you don't switch your main  fuse on your preamp and listen to it both ways.

Hi-Fi Tuning used to claim no directional difference, but I tried 10 of them and they were all the same direction. The same with the original SR fuses. Even cheap fuses are directional. I suspect the place to look is in how the fuses are made.

I really don't understand why anybody would bother to say that fuse direction doesn't matter. None of us who do hear a difference care what you think. And you, of course, don't care what we think. For about thirty years I heard this nonsense argument. Enough!!!

Wolf_Garcia, you are wasting your time. I took EE cources and took enough more physics courses to get a major. I know physics has not totally mastered natures laws, so you cannot say there is no physical explanation in EE for why fuses would differ. But the expensive SR Black fuse are both expensive and work quite well. Today I'm going to change the direction of the five of them in my line stage and amp. I am going to go with the best sounding direction.
