What direction should Hi Fi tune fuse be installed


What direction should Hi Fi Tuning fuses be installed? They have a little arrow and I would think it would point the direction of AC flow but maybe it points to the AC source?? SEEMS to sound better that way. I know someone will say put it the way it sound better but i have 3 fuses here. That is 6 possible ways. Not in the mood for that. The arrow must mean somethuing. What about Furutech? Thoughts welcome. keith

I know this: a few decades ago, I had some Monster Cable ICs with directional arrows. I had changed something on my stereo and had the ICs off of it. These ICs were going from preamp to amp. After reconnecting everything, I sat down to listen; but something didn't seem right. I couldn't put my finger on it; but it was enough to prompt me to get out of my chair and check everything. I found one of the two IC cables was plugged in backwards, ie. the arrow on the cable was pointing the wrong way. I corrected the orientation and sat back down to listen. Everything was good. That blew me away. I became more open minded about cables and other tweaks after that. I have not, however, gotten motivated to trial fuses.
If the impedance of Cu wire is slightly different in the direction of the draw vs. the other direction, then I would think that this difference is measurable. Perhaps fuse and cable companies know this and measure this; but for the sake of competitive advantage, do not care to reveal it. If wire impedance is slightly higher in one direction than the other, then it could follow that signal noise is slightly lower pending orientation of the wire. Lower signal noise could be perceived as better sound quality.

So who among these esteemed EE's could perform these delicate measurements? And be willing? Or is it nonsense?
Tonywinsc, Mapleshade use to make power cords that had ribbons whose draw was one way for the hot and the reverse for the neutral. I still have some somewhere in my boxes. Other companies copied them. Kondo use to make both silver and copper wire with the draw known. Synergistic Research zaps their fuses on their Tesla coil and does so both ways.
Tonywinsc, in the case of the Monster IC's (and most similar IC's) directionality as shown by the arrows has to do with the fact that the shield is only connected (grounded) at one end and not the other. I think we are talking about something else as concerns fuses.
Yes, I know. I was just sharing an antidotal story about my discovery of the impact of subtle things on the quality of the sound.
