Question about suitable fuse metals

@lcherepkai 👍👍  agree…for me it was a poorly wired outlet with old crumbling insulation which started to smell, turn brown and popped a breaker.  Wires/cords are most often the problem and should be inspected regularly.  

I am more concerned with damaged gear than the prospect of a catastrophic fire.  While there is the possibility that different conductors in the fuse will change the sound, any such changes would most likely be adverse, as compared to no fuse at all; your first experiment should be to bypass the fuse holder entirely.

The "magic" fuse (or insane elimination of same) efficacy myth stands to live on through the high end expectation bias fog as long as there are people who say thing like, "the new fuse let me see the facial expressions of the musicians." The fuse isn't in the signal path. Bigtwin is simply pointing out a reality.

larryi :  I'm certainly down with that possibility.  How would I go about completely bypassing the fuse holder?

wolf_garcia:  I'm not selling anything here.  I don't stand to gain by convincing you or anyone else that replacing the stock fuses with sold copper or titanium slugs improved the sound.  As you pointed out, "Bigtwin is simply pointing out a reality."

Well, that's exactly what I've done.  The reality is that by replacing the fuses with either copper or titanium slugs, I was able to hear more deeply into the sound and no, "the new fuse let me see the facial expressions of the musicians." did not occur.  However, listening to track #10, Emmeleia, from Into the Labyrinth by Dead Can Dance, it was not only easy to hear the inhalations as the singers took in breath, I could also clearly hear the parting of their lips after they closed their mouths, probably the wetting of their lips.  I've heard this in my system before but in a muted sort of way.  This was rather clear to my ear.  And this sort of insight occurred over and over again, listening to familiar discs.  Now, I suppose it could be some sort of expectation bias, if one exists that actually improves my hearing :)

Bigtwin:  I looked up your system and wow, that's a nice set up.  Sorry the audiophile fuse didn't benefit your system at all.  In my case though, I didn't try an audiophile fuse.  I tried a solid piece of 99.99% pure copper.  Maybe you should give that a try.

The only fuse experimentations I've ever done are:

1. When having to replace a fuse in my old (modded) Hafler DH220, I replaced the glass fuses with ceramic ones.  Not audiophile fuses, just different material.  I did, in fact, detect a slight difference for the better.  Maybe it was the ceramic, maybe they were just constructed with better materials, but the difference was there.  I have heard similar testimonials from others re: glass vs. ceramic.
2. I replaced the fuses on the back of my Maggies with sterling silver tube.  I do not blast them at high volume, so am not concerned with damaging the speakers.  Again, I noticed a difference.  The sound, while originally good, seemed to crystallize a bit, if that makes any sense.  If it doesn't............?  🤷‍♂️

All that said, this thread has induced an interest in swapping the silver tubing on the Maggies with copper tubing to see what difference it might make in the sound.  I expect there would be a discernible difference, perhaps adding some warmth?
