HiFI Fuses ?

Remember that IsoClean fuses are directional (big difference), cheaper($25@), and in the opinion of me and many who have tested both, sound better.

Ah yes, directionality would not matter were the connections in the component to not involve ground, but alas they do and so directionality matters. The neutral is not just the opposite flow of the hot. Anyone who has ever reversed the direction of a fuse and heard the difference could have told you this.

It is another matter on speaker wires. Again directionality matters, but that is not the topic here.

inpep---, so the neutral does no duty relative to serving as a ground often for the circuit and the chassis? Also stop switching the discussion to speaker-wires. They have nothing to do with this thread.

All that I can say to both you and Metro is that you should listen first and consider afterwards whether your understanding of circuit design can cope with what you hear. I know you hold desperately to the predilection that fuse direction cannot matter and want no evidence that you are wrong.

Inpep___, I have no need to provide you with evidence any more than you have to provide it that ac within components is the same as in speaker wires and phono wires. If you have personal experience that you can hear no difference in fuse direction that should be satisfactory for you, but don't pretend that those who hear a difference cannot be given your expertise in understanding electronics.

I have no idea how a direction is established with the IsoCleans or holds on other fuses. I did ask the IsoClean people at CES, but they just smiled. I do know, however, that when I put them in counter to the correct direction with the hot wire toward the transformers, they do not sound as good as the other way around.

Metro04, I don't mean to be confrontational, but certainly you have encountered performance improvements that make little sense from a EE perspective. I know full-well that we have different systems, rooms, tastes, and hearing. There is little evidence that can "prove" why power cords sound different, why interconnects sound different, why Sun Mook Mpingo disks work, etc. If some people don't hear such differences and don't, I attribute this to all of the above. I very much resent those who hear no differences dismissing those who do as not understanding "physics" or as delusional. It is entirely possible that they don't understand "physics" and that their personal biases keep them from hearing the differences.

If I hear a demonstration of a device or tweak that works, I don't want "proof" that it does. I would like to have some inkling of how it works, but concede that this is of secondary importance. When Lloyd Walker first told me to switch the direction of the fuse in my Walker modified AHT phono stage, my reaction was to be dismissive, but I tried it. He was right. I was also dismissive about dc voltage drainage and minimizing it by switching the ac cord. This also proved, at least on many components, to be quite important. I could go on and on.

inpep..., actually I see insisting that there be an explanation for why something should sound better as an indication of a closed mind. If something sounds better good science should seek to account for this even if it means going further than normal electrical engineers credo. I am with Benie in a practical sense relative to my audio system, although I would really like to know why the effect of the IC vanishes after a while and why the Mpingo disks don't always improve the sound of the component, and why an isolation transformer can help in many respects while hurting the sound in other respects. etc.
