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

For my $$$ it stops with the new improved Audio Magic Super Fuse. I admit I have not compared the Super Fuse to any of the various HiFi Tuning Fuses, Furutech fuse, Isoclean fuse, Synergistic Research fuse, Acme fuse, Audio Horizons fuse or any other aftermarket fuse I might have overlooked.
I had all three Furetech, Iso Clean and Hi fi tuning and tried them all on the Expousre 2010s. As annoying as it is and stupid as it is they all had a different sound. Where does it stop?/
Audioman58, SR claims they zap them both ways on the Tesla coil and thus it doesn't matter. But now I guess they do recommend what I've always found best.
I have tried everybrand out there I have settled on the Synergistic research
Fuses they seem to be a bit more warm sounding with excellent layering of instruments. As far as direction I asked Ted Denny the owner of Synergistic
He stated going with the writing going in the direction of the current flow
Should sound best ,others have said differently,I have stuck with current flow and have not been dissapointed. I do clean all contacts first with 90%
Alcohol or Caig . Using the walker SST conductive paste is also an added
Bonus for all connectors.
Just curious,Geph0007. Have you noticed any real improvement in sound now that you have the fuses? I am vasillating on buying some.
One direction of ac goes through the transformer windings as they are drawn. Also one direction of ac is at the live end of the switch. All that I can say is that whatever the explanation, the directions of fuses sound different.
Not having experimented with it, I am not in a position to take a position on fuse orientation, but fwiw it should be pointed out that ac current does not flow in one direction, it oscillates back and forth in both directions.

For a long time Hi-Fi Tuning claimed there was no direction, but I always found there was, but it was predictable judging this from the printing on their fuses. With IsoCleans I have always found the arrow going with the hot side input is the best sounding, so I would confirm the current flow direction is the right direction for the arrow.

I should say also that when Synergistic Research tunnels fuses they do so in the direction of current flow. This greatly improves the sound as does painting the glass with AVM paint.
Put all of the fuses in. Then start listening to the music. Swap direction of the first fuse and listen again. Choose the direction that sounds best. Now move onto the second fuse and do the same. Finish with the third fuse in the same way. You should then have the best sound at the end and the fuses orientated the right way (assuming you can pick fuse direction on your system). I find it quite noticeable with fuse direction. I have a combination of Hi-Fi Silver Star fuses and Furutech fuses.
I just looked inside to see which side has the wires to the transformer and which appear to have nothing. keith
I use IsoClean fuses that have an arrow on the glass body of the fuse. I tried them both ways and decided that the sound was better with the arrow pointing in the direction of the current flow.

For mains fuses: With the power cabled unplugged from the IEC, use a test meter to check for continuity between the "hot" IEC prong and the fuse holder clips (with the fuse out) and then place the fuse with the arrow pointing toward the clip with no continuity in the fuse holder (AC flow direction).

For internal fuses, using a meter to check for continuity is more complex. It is usually best to try it both ways and decide which sounds better.

Good luck and Happy New Year!
